Simulation Engineer

Full Time, San Francisco

About Us

Navier is building the boat of the future! We are a fast-growing startup in the maritime space led by MIT engineers with a passion for boating. Our DNA is one part maritime, one part Silicon Valley tech and one part aerospace. Our first product, the Navier 27, is a hydrofoil electric boat speedboat that is 90% more efficient than a traditional speedboat. And, it flies above the surface of the water avoiding discomfort and motion-sickness in rough weather (not to mention foiling is a super cool experience).
While Navier 27 will initially be sold to boating enthusiasts, our aspiration is to create radical disruption in waterborne transportation. We believe that achieving a step-function decrease in the operating cost of small vessels - making them as cost effective to operate as a car - will unlock a compelling and meaningful opportunity in transportation. That is, a scalable interurban mobility solution for our congested coastal cities.

Role Description

The Navier boat flies like an aircraft through the water, using a flight control system and control surfaces on the hydrofoils to actively maintain its balance. A key part of the flight control system development is a high fidelity simulation environment that lets us test our control laws before deploying them on the water. You will play a key role in developing this simulation environment, including the hydrodynamic model of our foil system, models for the sea state, and models for the boat’s sensors and actuators. You will also be actively involved in testing the flight control system, and collecting data that may be used to refine the simulation.
We are an early stage startup. You will begin as an individual contributor within a small close- knit team leading the development of a major component of our product. As a rapidly growing company we expect this role to evolve over time with opportunities to manage a team as we grow our headcount. The ideal candidate is passionate, driven, and excited about playing a key role in bringing our first product to market.

  • Develop a simulation environment that models the dynamics of our vessel, foil system and other wave body interactions
  • Develop models for the sensors and actuators used in the flight control system
  • Connect the simulation environment to the control law for both software-in-the-loop and
    hardware-in-the-loop testing
  • Work closely with our flight controls engineers developing the boat’s control law
  • Analyze flight test data and use it to refine the simulator

  • Experience with low-order aero- or hydrodynamic modeling methods (e.g, AVL, XFOIL)
  • Previous experience working on dynamic simulation environments for boats or aircraft
  • Strong coding abilities in C++ and Python.
  • 3+ years of relevant industry experience.
  • Enjoys working with a high degree of autonomy and solving challenging and loosely defined problems
  • Able to work in a fast-paced early startup environment
  • Is comfortable spending time on a boat on occasion to perform real-world testing


  • Experience with software like GHSport or other stability analysis tools for naval engineering
  • Familiar with ROS, PX4, or other autonomous systems and autopilots
  • Previous experience working for aerospace, automotive or marine industries
  • Passion for, and experience with boats / maritime
