The Crown Is Yours
As a Fullstack Engineer, you'll tackle complex features across the stack - from dynamic microfrontends to high-throughput, event-driven services. In this role, you'll design and build within a distributed architecture where reliability, scale, and long-term maintainability matter. Working closely with Engineering, Product, and Design teams, you'll deliver resilient solutions that hold up under real production load. You'll be trusted to solve tough technical challenges, support critical systems, and mentor engineers while raising the bar for speed, quality, and system design.
What you'll do as a Fullstack Engineer

• Design, build, and maintain fullstack features within a distributed, event-driven architecture using .NET and React.
• Own technically complex work from design through implementation, deployment, and long-term support.
• Develop APIs, microservices, and microfrontends that enable fast, reliable product experiences.
• Write clean, well-tested, and performant code with an eye toward scalability and maintainability.
• Investigate and resolve production issues using observability tools and system logs.
• Collaborate closely with engineers, product managers, and designers to plan and deliver solutions.
• Review peer code thoughtfully, offering feedback that improves clarity and quality.
• Utilize AI tools like ChatGPT, Copilot or Claude AI.

What you'll bring

• Bachelor's degree in computer science or any suitable combination of education, experience, and training.
• 2+ years of experience in C#/.NET development with a strong understanding of object-oriented principles.
• Proficiency with modern JavaScript frameworks - React, Angular, or Vue is a plus.
• Familiarity with distributed systems, asynchronous communication patterns, and Docker, Kubernetes, and AWS.
• Experience with SQL or NoSQL databases.
• Strong understanding of system design principles, scaling strategies, and architectural trade-offs.
• A collaborative approach to reviewing code that elevates team performance.
• A bias for action, sound technical judgment, and a team-first mindset.
• Good level of verbal and written English for clear communication within a global team.
