Cbf Jobs (NOW HIRING)

We are seeking an Applied Scientist to join Compass. In this role, you will develop the core Control Barrier Function (CBF) algorithms that form the mathematical foundation of the Compass safety system. You will ensure they don't just work in theory but perform reliably on real robots under real-world conditions.

You will push the boundaries of concepts central to CBFs: computing robust invariant sets, designing hybrid system formulations that handle contact transitions and mode switches, and developing backup-set approaches that leverage learned policies and multiple controllers. A key challenge of this role is bridging the gap between the mathematics of set invariance and the realities of hardware, including sensor noise, model uncertainty, computational budgets, and discrete state transitions. You will ensure that these algorithms are not only provably correct but also implementable within a safety-critical architecture that must be certified by a third-party.

You will contribute directly to the next generation of CBF theory and its practical deployment across Amazon's diverse robot fleet.
Key job responsibilities
Develop and implement novel CBF algorithms that provide formal safety guarantees while minimizing conservatism to maximize the permissible operating envelope for each robot platform
Compute and refine invariant sets for complex, high-dimensional robotic systems, developing scalable methods that go beyond what existing analytical approaches can handle
Design formulations for hybrid dynamical systems, handling discrete mode transitions (e.g., contact/no-contact, stance/flight phases) with provable safety across switching boundaries
Address the theory-to-practice gap by developing methods that are robust to model uncertainty, sensor noise, actuation delays, and computational latency
Create reduced-order and full-order dynamics models with both white-box and black-box approach
Implement real-time optimization solvers that execute within the tight timing budgets of safety-critical control loops
Develop formal arguments and documentation sufficient to support third-party safety certification of algorithms
Validate algorithms through rigorous simulation and hardware experiments, characterizing failure modes and quantifying safety margins
Contribute to the theoretical foundations of CBFs through publications at top-tier controls and robotics venues
Collaborate with perception, planning, locomotion, and manipulation teams to accommodate the needs of upstream and downstream systems

About the team
Work with the inventors of control barrier functions on a novel, universal approach to safe autonomy: one that scales across mobile robots, manipulators, mobile manipulators, and future robot platforms with dynamic stability.

You'll push the boundary of safe performance by integrating safety with motion planning, RL, and foundation models, ensuring that safety is never a blocker to robot performance. Your work will underpin robots operating alongside people at Amazon's unprecendented scale.
