• Build relationships across global engineering teams and influence the wider technical roadmap.
• Mentor colleagues and take an active part in engineering interviews to scale the team.

Required profile

• Significant experience building web-based applications.
• Experience managing web architecture at scale (20k requests per minute and above).
• Experience breaking down large pieces of work and guiding implementation choices for a team of engineers.
• Curiosity to grow in areas outside your main expertise.

Required skills

• Proficiency with AI coding tools such as Claude Code, Codex and Cursor across the full software development lifecycle.
• Backend expertise in Go, Ruby/Rails, Python, Scala and/or Rust.
• Relational databases (PostgreSQL, MySQL) and NoSQL backends such as Redis, DynamoDB or ElasticSearch.

What we offer

• Competitive salary and equity options.
• A low-hierarchy, high-ownership environment with flexible working and continuous learning.
