Produce and ship high-quality, well-documented code

• We highly value the analysis phase on software delivery. We're putting a heavy emphasis on upfront technical designs, team reviews, and smart slicing. You can expect to focus on quality, which we believe drives the velocity our customers need.
• We think success comes from a space where you're given time, support, and autonomy to improve yourself, our systems and our processes. Our lean toolbox enables you to monitor your constant improvements (Kaizen, PDCA) in a collaborative way with your peers and manager.
• Our engineers, working in cross-functional teams, dedicate themselves to one feature at a time.
• We value the efficiency and productivity of our engineers: that’s why we provide each of our engineers with licenses for Cursor or Copilot, enabling them to focus on what they do best – coding innovative solutions

Skills and AI tools this role asks for
Questions you could be asked
- What's a project where you used Copilot hands-on?
- Walk me through how you've used Cursor in your day-to-day work.
- What are the limits of Go that you've run into, and how did you work around them?
- What's a project where you used Ruby hands-on?
- Walk me through how you've used Kotlin in your day-to-day work.
Adapt your resume
- List these exact terms on your resume: Copilot, Cursor, Go, Ruby, and Kotlin. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
