Mid-level Software Developer (Ionic/Angular/.NET) — MVP → Big Launch

At apeirum , we turn bold visions into digital realities—with focus, sharp execution, and zero waste. We’ve partnered with a small start-up where the MVP is live and we’re now gearing up for the big launch . If you love building great software, take initiative, and use AI tools to work smarter and deliver faster, this is your runway. TASKS - WHAT YOU'LL BE DOING Design, develop, and maintain applications using .NET (preferably) or another object-oriented language. Apply SOLID principles and design patterns to produce clean, maintainable code. Implement and integrate REST APIs . Work with relational databases (SQL Server, MySQL, PostgreSQL) — ideally with Entity Framework . Write and maintain automated tests to ensure code quality. Collaborate with the frontend team and contribute to Angular apps ( React knowledge is a plus). Leverage AI-assisted coding and productivity tools to speed up development, improve quality, and optimize workflows. Own your tasks: work autonomously and proactively solve problems. Contribute to infrastructure discussions and help improve our technical processes. REQUIREMENTS - YOU'RE GREAT FIT IF YOU Hold a Bachelor’s or Master’s in Computer Science, Software Engineering, or a related field. Have 3–5 years of professional software development experience (mid-level). Communicate clearly and confidently in English . Are motivated and love creating software that makes an impact . Care deeply about product quality and the value it delivers to users. Are product-minded —you think about the why , not just the what. Work self-driven and thrive in small, async, distributed teams. See challenges as opportunities and are ready to grow into more responsibility. Nice to haves: Experience with Domain-Driven Design (DDD). Broader infrastructure knowledge and willingness to dive into DevOps-related topics. TECH STACK OVERVIEW Frontend: Angular & Ionic (React experience is a plus) Backend: C#, .NET Core, Web API, Entity Framework Cloud: Swiss-hosted Supabase Database & Backend Services: SQL (SQL Server, MySQL, PostgreSQL) and Supabase Bonus: Python MINDSET & COLLABORATION Strong problem-solving skills and critical thinking . Passion for AI-driven productivity —you actively use AI tools to accelerate development, improve quality, and explore new possibilities. Comfortable in a fast-paced, startup-like environment with a problem-solving, AI-first approach. HOW WE WORK (AND WHY IT'S FUN) AI-assisted, pragmatism-driven: Use AI tools where they add speed/quality; use classic engineering where it’s better. Small team, big ownership: Autonomy, clear goals, and direct impact from design to deploy. Ship → learn → iterate: Tight feedback loops from MVP to launch with real users. BENEFITS 23 days of holidays Learning budget (courses/conferences) Top-tier hardware Flexible hours Remote work (default) Yearly strategic off-site READY TO MAKE AN IMPACT? We’re after someone who thrives in a fast-paced, product-driven environment— adaptable, curious , and eager to solve real problems with smart, modern tools . If that’s you, we’d love to hear your story. Apply: Send your CV and 1–2 links (GitHub, demo, or a short write-up of a feature/service you shipped—bonus if you used AI-assisted tooling). No perfect match? If you bring strong .NET fundamentals (and ideally Ionic/Angular ) with a builder mindset, we still want to hear from you.
