About the role

Responsibilities

  • Build and scale core optimization algorithms used directly in production.
  • Write optimization systems (e.g. MILPs, LPs, heuristics, etc.).
  • Build and maintain data pipelines that operate at real production scale.
  • Move quickly from idea → implementation → customer usage.
  • Contribute to long-term product and technical direction.
  • Willingness to do whatever is needed technically, from deep algorithm work to integration and tooling.
  • Comfortable being forward-deployed: talking to customers, understanding constraints, and solving concrete problems.

Requirements

  • Experience writing optimization algorithms (MILPs, ML, DP, RL, stochastic models, heuristics, or similar).
  • Generalist who can operate across the stack when needed.
  • Ships code fast and often; not a perfectionist.
  • Comfortable working in ambiguity with incomplete information.
  • Extremely hardworking when part of a strong, mission-aligned team.
  • Background may include top startups or big tech, ex-founder / founding engineer experience, or serious side projects that are shipped and live.
  • Comfortable with Python and TypeScript.
