You’ll take ownership of development from concept through delivery, contributing to architectural decisions and helping define long-term technical strategies.

Benefits

  • Supportive community of skilled, thoughtful professionals invested in your growth
  • Emphasis on sustainable work-life balance and personal well-being
  • Free moving assistance and access to sick child care services
  • Shared car program and office space available for personal events
  • Internal training, community-led tech discussions, and access to extended learning programs like Cloud Academy
  • Over 300 hobby groups—from archery to winter swimming—funded and supported by the organization

Preferred Qualifications

  • Familiarity with SwiftUI
  • Interest in creating refined animations in collaboration with motion designers
  • Experience with C++ or Flutter
  • Background in fullstack development
  • Knowledge of Finnish is beneficial but not required

Company Culture

Work in a low-ego, low-hierarchy environment where curiosity and adaptability are valued. The team prioritizes inclusion, professional development, and meaningful collaboration. With a strong commitment to diversity and equity, everyone is encouraged to bring their whole self to work. If you’re unsure whether you meet every requirement, we still encourage you to apply—what matters most is how you contribute to the team’s success.
