  • 7+ years of engineering experience with a strong track record of shipping high-quality, high-complexity systems at scale

  • Experience working closely with a cross-functional product team

  • Excited to primarily be an individual contributor with a high degree of ownership

  • Comfortable operating in an early-stage, fast-paced environment with real ambiguity and agency

  • Impact-driven, with a bias towards action and ownership

  • Customer-centric approach and a fast working pace

Bonus points for:

  • Experience building B2B software and/or fintech software

  • Experience at seed or early-stage startups (for example, being a first-3 engineer at a company)

  • Experience building and maintaining open source software

  • Previously started a company or launched personal projects
