Continuous improvement

  • Surface gaps, propose improvements, and help elevate engineering practices on the team.
  • Identify opportunities to improve speed, reliability, and developer experience.
  • Contribute to building technical clarity, documentation, and internal knowledge.

Why you’ll love this role

  • You’ll directly accelerate the roadmap for one of Keep’s most impactful product areas.
  • You’ll own meaningful features and see your work ship to production quickly.
  • You’ll join a fast-paced team where trust leads to autonomy and growth.
  • You’ll collaborate closely with engineering leadership and influence product decision-making.
