We’re an experienced team that values concrete results, clear thinking, and craftsmanship. We love complex problems and shipping polished software with great people.

Our Culture

At Hamina Wireless, we believe great work comes from ownership, curiosity, and action. We're looking for teammates who learn continuously, take initiative, and collaborate openly. You’ll work alongside people who care deeply about what they build, and about the people building it.

• Work closely with product and design to turn user needs into robust APIs and elegant UI experiences.
• Write clean and reliable code that scales.
• Shape our architecture and contribute to decisions on how we build and deploy our systems.
• Optimize performance, reliability, and scalability across the stack.
• Collaborate across disciplines. You’ll have plenty of opportunities to dive into new areas and shape the product end-to-end.

What We’re Looking For

Must‑have

• Results‑driven and passionate about solving customer problems.
• Solid experience building full-stack applications with TypeScript, React, Node.js and PostgreSQL.
• Ability to design and implement APIs, modular systems, and maintainable codebases.
• Excited about integrating AI tools into your daily work.
• Good taste and an eye for detail.

• We encourage exploring and learning new technologies and techniques like 3D and AI tools.
• Work in a collaborative environment where initiative, curiosity, and craftsmanship are valued.
• A tight‑knit, pragmatic, and talented team that enjoys what they do.
• Flexible work culture centered around trust and autonomy. We value meeting teammates in person, but you don't have to come to the Helsinki office every day.
• Competitive compensation and benefits.
