We’re looking for a Senior Fullstack 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 the 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 takes 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.

- Define and align feature architecture with the Head of Engineering to ensure consistency and scalability.
- Ensure features meet Definition of Done, with appropriate unit, integration, and end-to-end test coverage.
- Support incident response and production issue resolution as per team standards.
- Actively contribute to team knowledge sharing and coach colleagues in technical best practices - potentially as a Tech Lead.
Essential Qualifications:
- 5 years of proven experience in building secure REST APIs using ASP.NET, as well as developing solid front-end applications with React are non-negotiable must haves.
