Job description
Fleetline writes optimization algorithms for enterprise trucking fleets. We work with some of the largest fleets in the country and are rapidly scaling our operations. **A bit about us** - Scaled from 0 to $Xm in contracts in under eight months; month-over-month growth is still increasing - Lean team of 12 based in New York City; everyone deeply cares about the company’s mission, our clients, and each other. That care translates into high standards, close relationships, and intensity. - Backed by a large seed round from top investors like BoxGroup, Base10, and more. **About the role** - 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 - In office in New York City is required. **What we’re looking for** - Has experience writing optimization algorithms (MILPs, ML, DP, RL, stochastic models, heuristics, or similar) - A 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 Pedigree is not important. We’re looking for people who are intelligent, gritty, curious, and good at moving quickly.
