• Create tools and editor extensions to speed up workflow across the team.
• Review, code, document, and collaborate across disciplines.

Requirements and skills:

• 5+ years of software development experience.
• Strong Unity and C# skills (C++ experience is a plus).
• Solid fundamentals in back-end and networking for games.
• Practical, data-driven approach to performance and reliability.
• Team-oriented, with strong problem-solving and communication skills.

Language: Excellent English (written and spoken). No Swedish required.

Location: On-site at our office in Uppsala. No remote or hybrid work.

How to apply: Send your CV, portfolio/GitHub, and a brief about your shipped titles and specific contributions. Links to builds, trailers, or tech write-ups are great.
