Jobbeschreibung

Job profile

We’re looking for a Senior Full‑Stack Engineer who brings deep technical expertise and a collaborative mindset to our product development team. You will work with a modern microservices architecture, building scalable backend services using ASP.NET Web API with C#, and intuitive frontend interfaces using mainly React and TypeScript. This is a hands‑on engineering role with a 50/50 front‑/backend focus, ideal for someone who likes to take ownership, thrives in a dynamic product team, and enjoys mentoring others. This role could easily become a Tech Lead role in a foreseeable future. If you’re passionate about designing high‑impact software in a cloud‑native environment, we’d love to hear from you. Poland‑based role offers remote flexibility, but we value in‑person collaboration. Our team meets in Poland for at least one week each quarter, so we request all applicants to be located in Poland. This is not a globally remote role. Poland residency is required. Contract form is Umowa o Pracę (brutto).

What you will be responsible for

1. Collaborate proactively in refinement sessions with product and tech teams to ensure clarity and feasibility of features.

2. Design, implement, and maintain scalable web APIs using ASP.NET and microservices architecture principles.

3. Develop responsive user interfaces with React and TypeScript that enhance usability and performance.

4. Work closely with Product Owners to clarify feature requirements and ensure business context is well‑understood.

5. Define, design and align feature architecture with the Head of Engineering to ensure consistency and scalability.

6. Ensure features meet Definition of Done, with state‑of‑the‑art unit, integration, and end‑to‑end test coverage.

7. Support incident response and production issue resolution as per team standards.

8. Actively contribute to team knowledge sharing and coach colleagues in technical best practices – potentially as a Tech Lead.
