Staff Research Engineer (LLM Pre-Training)
At JetBrains, code is our passion. Ever since we started back in 2000, we have been striving to make the world’s most robust and effective developer tools. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create.
We are working on an ambitious new platform that provides AI capabilities to all JetBrains products. Our platform is based on models developed in-house for writing and coding assistance, as well as integration with our strategic partners.
We are looking for a Research Engineer who can contribute to training foundation models for coding tasks. You’ll be working on developing Large Language Models from scratch and deploying them into production environments where they will be accessible by end users across the globe.

JetBrains runs a Flexible Hybrid model, so most roles are tied to one of its 15 offices across Europe (including Amsterdam, Prague, Munich, Berlin, Belgrade, Warsaw, Madrid, London, and Cyprus), the Americas (Foster City, Marlton, and Waltham), and Shanghai. Even roles posted as remote are usually locked to a specific country, so check the location listed on a job before applying.
No. JetBrains hires across engineering, design, UX research, marketing, sales, and operations, and its careers page is explicit that you do not have to write code to be a match. Every hire, technical or not, is asked to complete a test assignment, which is how the team sees the actual skills a role needs in action.
Alongside hybrid flexibility and up to 30 days a year working abroad, JetBrains provides in-office meals, snacks, and drinks, a gym subsidy, a learning and development budget for conferences, books, and courses, and a top-spec equipment setup. Health, dental, vision, mental-health support, pension, and parental leave are included, though the exact coverage depends on the country you are based in.
It runs in stages: an application with a CV and short cover letter, an application review, a recruiter call, and a team interview. You are then given a test assignment, for any role and not just engineering, which can usually be done from home. Potential teammates review it, followed by a final interview and a reference check with three contacts before a decision is made.
JetBrains looks for people who raise the standard around them, care about why the work matters, and are comfortable owning decisions without close supervision. Having stayed private and profitable for more than two decades, the company builds without short-term external pressure, so it suits people who want the space to take their time and get things right rather than chase quarterly targets.
