Thank you for exploring opportunities at Ribbit! We look forward to speaking with you.Note: the Careers page is under maintenance; actual details and interview process may differ slightlyNote: We read everything that comes our way. Let your outstanding résumé (cover letter and design portfolio encouraged but optional) do the talking. For significant questions or comments, contact us at CompanyFounded in 2020, Ribbit builds and operates autonomous airplanes. We develop technology that enables uncrewed gate-to-gate operations, having completed hundreds of autonomous flight hours on different aircraft, flown 10 K+ hours in simulation, and secured flight authorities for remotely and optionally piloted flight. From defending sovereignty to delivering food and medical supplies, we are a trusted partner that businesses and governments rely on to test, operate, and deploy affordable autonomous aircraft. You can check out our videos here.We believe that technology should be developed for and with the customer. In 2023, we signed our first federal contract with the Government of Canada, during which we performed Canada’s first autonomous gate-to-gate flight between two airports. Since then, we have won several additional contracts, including contracts with the National Research Council of Canada (NRC) and the Department of National Defence (DND) spanning platform, mission, and collaborative autonomy. We pride ourselves on knowing the customer better than themselves, serving them better than anyone else, and ensuring they succeed in a world with everyone else.This year alone, we performed the world's first demonstration of collaborative teaming between an autonomous airplane and an autonomous helicopter. We also deployed Canada's first optionally piloted aircraft with a military callsign. We are now building novel autonomous aircraft for DND and Canada's allies, aligning our immediate defence clients with a backlog of interest across northern wholesalers, public safety agencies, freight forwarders, and humanitarian organizations.



Autonomy is reshaping the way we move, understand, and protect the world.Our team has years of experience with piloting, commercial drone operations, and autonomous mobile robotics—we're concentrating the world's best software, robotics, and aeronautical expertise to pursue our mission of making air transportation accessible to everyone. If you’re up for the challenge, we want to hear from you.Position OverviewAs a Senior Flight Controls Engineer, you will collaborate with peers to:Lead development of flight control for autonomous fixed-wing aircraft. You will shape its architecture and roadmap, lead design reviews, and hold the bar on code qualityOwn the aircraft modelling behind the control system, including trim and operating-point models, actuator and propulsion models, and the simulations used to design and verify control lawsStay hands-on: design and tune control laws yourself, write production C++, and review the hardest changesRepresent control in design reviews with the navigation, state estimation, hardware, and flight-test teams, and mentor the engineers who join the teamWork with flight-test engineers and safety pilots to plan and fly test campaigns, tune control laws during and after flights, and turn pilot feedback into improvementsYour key objectives will include:Building and maintaining high-fidelity models of real aircraft from first principles (6-DOF equations of motion, aerodynamic coefficients, mass and inertia, propulsion and actuator dynamics), refined by system identification from flight dataTrimming and linearising the aircraft across its envelope, and using the results to design, analyze, and schedule control laws (e.G. stability margins, robustness to model uncertainty)Designing and tuning control laws for automatic takeoff and landing: ground roll, rotation, crosswind technique, glide-path tracking, flare, touchdown, rollout, and go-aroundDesigning energy management and lateral path following (e.G. TECS, L1 or similar nonlinear guidance) that hold up in wind and turbulenceImplementing envelope protection and failure handling (e.G. stall,
