PhD jobs in Spain: where researchers work, what they earn and which residence permit they need in 2026

A PhD holder in Spain works in one of three places: a university, a research centre such as CSIC, or the R&D unit of a company. All three are open to a foreigner with a residence permit, permanent posts included: the law does not require citizenship. A postdoc on a national programme earns from €31,200 to €40,000 a year, a professor from €40,000.

What PhD holders do in Spain

Spanish science is bigger than many expect. According to INE, the country had 184,382 full-time-equivalent researchers in 2024, and R&D spending reached €23,931 million, or 1.5% of GDP. More than half of that money, 55.8%, is spent by companies. Universities account for 24.9%, and public research bodies for most of the rest.

That gives three routes after the defence:

• University. 92 universities, 50 of them public, with 141,887 teaching and research staff. The career runs from a Profesor Ayudante Doctor contract to a permanent post.
• Research centre. CSIC and other public research organisations (OPIs), plus regional institutions such as ICREA in Catalonia and Ikerbasque in the Basque Country. The way in is through postdoctoral programmes and tenure-track contracts.
• Company. Pharma, biotech, energy, data science, engineering. The state subsidises employers who hire PhD holders, which is a useful argument in salary talks.

The academic route has a feature worth knowing in advance. Only 3.6% of staff at Spanish universities are foreign nationals, and 73% of staff at public universities work at the same university where they defended their thesis. So a foreigner usually comes in not through an ordinary departmental competition but through national talent programmes, described below.

How a foreign doctorate is recognised in Spain

Spanish higher education has three levels: Grado, Máster and Doctorado. A foreign doctorate is not homologated in Spain; instead it is declared equivalent to the Doctor level. This is called a declaración de equivalencia, and the decision is taken not by the ministry but by a university of your choice (Royal Decree 889/2022, second additional provision). What matters:

• The university compares the programme and the thesis. It usually asks for the diploma, a transcript with hours, a copy of the thesis with the committee, a CV, a sworn translation and an apostille. Each university has its own rules and fee. A decision takes up to six months.
• Once one university has declared the degree equivalent, another will not review it again. If you are refused, you may apply to a different university.
• Equivalence covers only the doctorate. It does not recognise your bachelor or master degree, and it gives no professional rights such as the right to practise medicine.

Many routes do not need equivalence at all. For the Ramón y Cajal and Juan de la Cierva calls, a foreign diploma is simply attached as a copy. A private company only needs the diploma itself, because researcher is not a regulated profession. Whether equivalence is needed for ANECA accreditation and a permanent-post competition depends on the rules of that procedure, so start it when your goal is a professorship. How ordinary degree recognition works is covered in our article on degree recognition in Spain.

University: from Ayudante Doctor to Catedrático

The ladder is set by the Organic Law on the University System, LOSU (Ley Orgánica 2/2023). There are two permanent civil-service bodies: Profesor Titular and Catedrático. Next to them are employment contracts, and a foreigner usually starts with one of these.

For accreditation to a permanent post, the law requires research or teaching experience outside the institution where the thesis was defended. Someone who defended abroad and works in Spain usually meets this condition automatically.

The key provision for a foreigner is Article 88.2 of LOSU. The general civil-service rule admits only EU citizens as funcionarios, but for universities the law makes an exception: foreigners lawfully present in Spain take part in accreditation and in competitions for Titular and Catedrático on the same terms as Spaniards. You need a residence permit, not a passport.

The law sets no general Spanish-language requirement, but universities promote their regional languages. In Catalonia, staff at public universities have to certify Catalan (Decree 128/2010); visiting professors are exempt, and the university may give new staff time to meet the requirement. The Basque Country, Galicia and Valencia have their own rules, so check them with the university before applying.

Research centres: CSIC and tenure-track

The largest employer of researchers outside universities is the Spanish National Research Council, CSIC, together with the other public research organisations (OPIs). They are governed by Science Law 14/2011 as amended in 2022. Permanent posts here are three civil-service grades: Científico Titular, Investigador Científico and Profesor de Investigación.

The usual way in is a tenure-track contract (contrato de acceso de personal investigador doctor): three to six years, with a review after the second year leading to the R3 certificate (established researcher). The certificate exempts you from part of the exams for a permanent post, and at least 25% of OPI places are reserved for R3 holders.

Here a foreigner has an easier time than in most public bodies. Article 26 of the Science Law expressly admits foreigners lawfully present in Spain to permanent-post competitions and allows EU and non-EU nationals to sit the exams in English. Selection is based on the CV. A researcher with an international reputation may also be offered a separate investigador distinguido contract for a term agreed by both sides.

Postdoctoral programmes in 2026: where to apply

The State Research Agency, AEI, runs annual calls that are the main way in for a foreigner. The money goes to the host centre for your contract, and you choose the centre.

Ramón y Cajal has a detail that helps foreigners: the requirement of 24 months of work outside the host centre is considered met if you obtained your doctorate entirely abroad. An ERC grant holder may receive up to 30% above the minimum salary. The María Zambrano and Margarita Salas programmes, often mentioned in older guides, ran in 2021–2023 and no longer hold calls.

How much researchers earn in Spain

There is no single salary: the state sets the base pay, while regions and universities add supplements. Below are the official 2026 table of the University of Salamanca and the minimums from the AEI calls.

The university figures exclude seniority supplements and the bonuses for assessed research periods (sexenios), which raise income noticeably over time. Other universities pay more or less because of regional supplements. For comparison with average pay in the country, see our article on working in Spain.

Working for a company: R&D, pharma, data

Companies spend more on research than universities and the state combined, and the state helps them hire PhD holders. Knowing these tools helps in negotiations: hiring a PhD costs the employer less than it seems.

• Contribution rebate. With a permanent full-time research contract, the employer pays social security for the researcher at a 40% discount for three years (Royal Decree 475/2014). Up to 15% of working time may go to teaching.
• Tax credit. The company reduces corporate tax by 25% of its R&D spending and by another 17% of the cost of qualified researchers working exclusively on R&D (Law 27/2014, Article 35).
• Torres Quevedo. An AEI subsidy to a company or technology centre for a three-year contract with a PhD holder.

Company vacancies are advertised in the usual way, and to work for a private employer a foreigner needs a permit, covered in the next section. If you plan your own technology company rather than employment, look at the startup visa.

Which residence permit a researcher needs

Both main routes for researchers are permits under Law 14/2013, and both are handled by UGE, the Large Companies and Strategic Groups Unit. Filing is online, and decisions come faster than at an ordinary immigration office.

• Research residence permit (Article 72). For researchers and scientific staff at universities, centres and companies, and for lecturers at universities and business schools. Issued for three years or for the length of the contract, renewable for two. When the contract ends, you may stay in Spain for up to 12 months to find a new job or start your own project. Since 7 August 2026 doctoral candidates are also processed on this basis; details are in our article on the research residence permit.
• Highly qualified professional permit (Article 71). Suitable when a company hires you as a specialist rather than as a researcher. There is a national version and the EU Blue Card; the term is three years, renewable for two.

Family members come with the researcher under the same law and may apply at the same time. After five years of lawful residence you can apply for permanent residence in Spain, and years on these permits also count towards citizenship. The full list of grounds is in our overview of Spanish residence permits.

Taxes: the Beckham regime and planning before the move

A researcher who moves to Spain under an employment contract can apply for a special tax regime, the Beckham regime (Article 93 of the Personal Income Tax Law). A contract with a university, centre or company qualifies, and so does civil-servant status. The law also names specialists working in training, research and development, if that work brings more than 40% of their income.

One condition applies to everyone: you must not have been a Spanish tax resident in the previous five years. The application is filed within six months of registering with social security, so the decision has to be taken before the move, not after. For a researcher with capital this matters even more: under the Beckham regime salary is taxed at 24% up to €600,000, while income and assets abroad are not taxed in Spain. How taxes work for wealthy families outside this regime is covered in our article on taxes in Spain for wealthy families.

Where to find research jobs in Spain

• EURAXESS Spain: the European job portal for researchers, with a Spanish section and relocation help.
• The AEI website: Juan de la Cierva, Ramón y Cajal and Torres Quevedo calls and their deadlines.
• University and CSIC portals: contract and permanent-post competitions; competitions for civil-service bodies are also published in the BOE.
• The websites of ICREA, Ikerbasque and regional talent programmes.
• Direct contact with a group leader. Postdoctoral programmes require a host centre, so agreement with the group usually comes first and the application second.

Key points on working in Spain with a PhD

• Jobs are in three places: universities, research centres such as CSIC, and company R&D units.
• Citizenship is not needed even for permanent posts: LOSU and the Science Law admit foreigners with a residence permit.
• A university declares a foreign doctorate equivalent, but AEI postdoctoral calls and company jobs do not require it.
• The main entry points are Juan de la Cierva and Ramón y Cajal; the 2026 calls take applications in November and December.
• The residence permit is the research permit or the highly qualified permit, both through UGE, with family and a path to permanent residence after five years.
• The Beckham regime is open to a researcher with an employment contract, but the decision is made before the move.

If you already have an offer from a Spanish university, centre or company, write to us: in a consultation we will go through the residence route, your family and taxes before the move.

Frequently asked questions

Do I need to have my foreign PhD recognised to work in Spain?

Not always. For the Ramón y Cajal and Juan de la Cierva programmes a foreign diploma is attached as a copy, and a private company only needs the diploma itself. Equivalence to the Doctor level is granted by a university of your choice; it matters mainly for those aiming at a university professorship.

Can a foreigner become a Profesor Titular or Catedrático in Spain?

Yes. Article 88.2 of LOSU admits foreigners lawfully present in Spain to accreditation and permanent-post competitions on the same terms as Spaniards. You need a doctorate, ANECA accreditation and a residence permit; citizenship is not required.

Do I need Spanish to work at a Spanish university?

The law sets no general requirement, many research groups work in English, and at CSIC the exams for permanent posts can be taken in English. In practice, though, teaching requires the language, and in Catalonia staff at public universities have to certify Catalan.

How much does a postdoc earn in Spain?

Under the 2026 AEI calls, the minimum salary of a Juan de la Cierva postdoc is €31,200 gross a year, and of a Ramón y Cajal researcher €40,000 gross a year. The host centre may pay more than the minimum.

Which residence permit does a researcher with a Spanish contract need?

Usually the research residence permit under Article 72 of Law 14/2013, which covers universities, research centres and company R&D units. If a company hires you as a specialist, the highly qualified professional permit or the EU Blue Card fits. Both are processed by UGE.

Can a PhD holder use the Beckham regime?

Yes, if they move under an employment contract with an employer in Spain or as a research and development specialist, and were not Spanish tax residents in the previous five years. The application is filed within six months of registering with social security.

Can I stay in Spain after my research contract ends?

Yes. A holder of the research residence permit may stay in Spain for up to 12 months after the research ends to find a new job or start their own project.
