Candidate FAQ
The questions candidates ask most often about this role - answered upfront.
Who is Accuris?
Accuris is an engineering intelligence company - formerly S&P Global's Engineering Solutions division and an integral part of the engineering ecosystem for more than 60 years. Our products - Engineering Workbench (EWB), the EMS platform and Goldfire - turn the world's largest repository of engineering standards and technical knowledge into connected workflows. They are used by engineering teams at Boeing, NASA and SpaceX, among many others - including the teams behind programs like NASA's Artemis.
What team would I join?
An Engineering Workbench engineering team in Gdansk, working with hiring manager Oleg. The team builds full-stack features - C#/.NET Core services with Angular frontends - across backend services, APIs and web applications, side by side with QA, DevOps, Product Owners and Business Analysts.
What do you look for?
Solid fundamentals and genuine curiosity: clean C#/.NET work, an understanding of how your code behaves in production, comfort across the stack (Angular included), and real stories about problems you owned end-to-end. We value honesty about what you know deeply versus what you have only touched.
What does the process look like?
Three stages: (1) an intro call with Mateusz (recruiter screen), (2) a ~1-hour conversation with the hiring manager covering technical topics and ways of working, and (3) a panel with two team members - one technical deep-dive, one focused on collaboration and culture. The whole process typically takes about 2-3 weeks, there are no take-home assignments, and you receive feedback after every stage. Interviews are conducted in English.
Where would I work?
Gdansk, Poland, on a hybrid model (3 days per week in the office). We are opening a brand-new office in the Alchemia complex in central Gdansk in Aug/Sep 2026. Gdansk is Accuris' second engineering hub after Denver - you would be joining at the greenfield stage and helping shape it.
What are the benefits?
Salary: 18 000 - 19 000 PLN gross/month (UoP) + annual bonus. On top of that, an employment contract (UoP - we hire for the long term), a private medical package, a Multisport card, life insurance, a 2 000 PLN annual wellbeing allowance, and all necessary equipment provided.
