About the RoleWe're looking for an
Applied Scientist to turn Sprinter's hardest logistics problems into optimization models and decision systems that get the right clinician to the right patient at the right time. Sprinter runs a two-sided operation - clinicians on one side, patients who need care at home on the other - and we must match supply to demand across large regions under complex constraints.
As an Applied Scientist, you will take ambiguous operational problems and shape them into well-posed tasks, strong baselines, and honest evaluations. The algorithms you build will answer questions like which clinician sees which patient, in what order, given drive time, appointment windows, and clinical constraints; how many clinicians to staff in each region next month; and how long a visit will take or whether a patient is likely to cancel.
This role sits at the intersection of research and engineering, blending scientific rigor with a deployment-oriented mindset. It also requires close cross-functional partnership with operations, product, and engineering stakeholders. The ideal candidate is a scientist-engineer who reasons from first principles about uncertainty and constraints, reaches for the simplest model that works, and can move from a formulation on the whiteboard to a decision that runs in production.
Hybrid & Office ExperienceWe operate on a hybrid schedule, working from the office Monday through Thursday, with Fridays designated as work-from-anywhere days.
We care deeply about work-life balance and are happy to provide flexibility when life happens. We ask that employees be in the office Monday through Thursday to collaborate with their teams while maintaining flexibility where it matters most.
Lunch is provided every day, and the entire team takes an hour to eat together. It's one of the ways we stay connected outside of meetings. You'll usually find us playing a board game before getting back to work.
What you will do:Modeling & Optimization- Turn ambiguous operational problems into well-posed optimization, forecasting, or simulation tasks.
- Build strong baselines and improve on them efficiently, adding complexity only when the value justifies it.
- Develop solutions across operations research, optimization, and machine learning, choosing the right tool for the problem.
- Run careful analysis and iterate toward decisions that improve real operational outcomes - cost per visit, clinician utilization, patient access, and visits completed.
Evaluation & Scientific Rigor- Design offline evaluations, simulated backtests, and live experiments that predict real-world operational impact.
- Find the gaps between a model's assumptions and messy operational reality before they reach production.
- Choose metrics suited to stochastic, constrained, and partially observed operational systems.
- Interpret and communicate results effectively to cross-functional stakeholders.
Collaboration & Delivery- Partner with Engineering to productionize optimization and decision systems reliably.
- Work with operations partners and SMEs to validate assumptions and review where decisions break down.
- Explain tradeoffs, uncertainty, and limitations clearly to product and leadership.
What you have done:- Strong foundations in operations research or optimization: modeling, algorithms, experimental design, and honest evaluation.
- Strong Python and SQL, the standard optimization and ML libraries, and the ability to run your own experiments end to end.
- Fluency with AI coding assistants (e.g., Claude Code, Cursor) in your day-to-day development workflow.
- Ability to turn an ambiguous problem into a well-posed optimization or forecasting task, discover and analyze related literature, and adapt/apply those methods to our tasks.
- Judgment about how uncertainty, constraints, and edge cases behave in real-world operational data.
- Interest in operations collaboration and applied healthcare impact.
What gives you an edge:- MS or PhD in operations research, industrial engineering, computer science, applied math, statistics, machine learning, or a related quantitative field; exceptional applied experience can substitute.
- Depth in a relevant area such as vehicle routing, scheduling, stochastic optimization, discrete-event simulation, queueing, or demand forecasting.
- Experience shipping optimization or decision systems that reached production and had material real-world impact.
- Hands-on experience with supply-and-demand matching in a marketplace, dispatch, or field-operations setting.
- Fluency deciding when an exact optimization approach beats a heuristic or learned one, and vice versa.
