Senior GNC Engineer at Boundary Layer Technologies (W19)
High speed container ships using hydrofoils.
About Boundary Layer Technologies

We make high speed hydrofoil cargo ships that compete with air freight.

About the role

The Company

Boundary Layer Technologies is building the future of zero emission maritime transport, starting with hydrofoiling electric passenger vessels. We are backed by Y Combinator, Fifty Years VC and Lower Carbon Capital and have built a world leading 26' fully electric hydrofoil prototype. We are a company of builders where rapid iterations and fast learning is in our DNA.

We are looking for a Senior guidance, navigation and controls engineer to own development and testing of the GNC systems on our hydrofoiling craft. 


  • Design and implementation of flight control system for electric hydrofoil vehicles. 
  • Provide analysis and guidance to other teams on flight dynamics, vehicle loads, actuator loads and sizing. 
  • Develop a sensor suite and develop the filtering and state estimation algorithms  Improve existing and develop the GNC workflow - simulations, hardware-in-the loop testing, integration, flight test, and post analysis for continual and efficient improvement. 
  • Improve our existing flight control software, sensors and state estimation on prototype hydrofoil craft Pamplemousse. 
  • Analysis of flight data and written and verbal communication of results Support testing activities 

Required skills and experience

  • Degree in engineering or physics (advanced degrees preferred)
  • Previously implemented flight controls on at least one functioning flying vehicle (drone, fixed wing aircraft, rocket, hydrofoil or similar, multiple vehicles preferred)
  • Proficient in  Matlab, Simulink and their embedded auto coders (C/C++ and Python preferred)
  • Familiarity with fixed wing vehicle physics (experience with hydrodynamics and hydrofoils preferred)
  • Familiarity with sensors, avionics, and state estimation 
  • Compared real world test data with simulation data to improve plant models 

Please still consider applying even if you don't match every listed expectation, as we are big believers in learning and growth. Here at Boundary Layer Technologies, we know that diverse perspectives foster the innovation we need to be successful, and we are committed to building a team that encompasses a variety of backgrounds, experiences, and skills.


No one has made hydrofoils this large before, let alone out of carbon composites.
