Full Stack Engineer

Full Stack Engineer Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further. ABOUT THE ROLE We are looking for a Senior Software Engineer to help transform our advanced robotics stack into a dependable product ready for the real world. This is a deeply technical and hands on role. You will write production code, integrate subsystems, and work directly with robots in both simulation and real hardware environments. You will be part of a focused team responsible for the application level software that connects control, navigation, perception, learning, and platform systems. Your work will ensure that these components operate as a coherent and reliable system that users can interact with seamlessly. This role involves close collaboration with engineers across multiple domains. You will contribute to architectural decisions, build prototypes, and iterate quickly. It is well suited to someone who enjoys working close to hardware and solving practical, cross disciplinary challenges. WHAT YOU’LL DO - You will develop and maintain application level software for humanoid robots. - You will integrate software components from controls, navigation, computer vision, reinforcement learning, and platform teams. - You will contribute to the structure and evolution of the application architecture and its interfaces. - You will work closely with the product and engineering teams to define priorities and deliver robust features. - You will debug complex robotic systems in both simulated and physical environments. - You will support on site validation efforts when needed and contribute to field testing. WHAT WE'RE LOOKING FOR - You have at least five years of experience in robotics or a closely related field. - You are highly proficient in C++ and have experience delivering production grade software. - You have a solid understanding of robotic subsystems including control, perception, navigation, and learning. - You are familiar with ROS or ROS2 or equivalent middleware platforms. - You are comfortable reading, understanding, and integrating code from a range of other engineering teams. - You have experience debugging systems on hardware and enjoy hands on problem solving. - You are a strong communicator and collaborative team member, able to work effectively across disciplines. WHAT WE OFFER - Meaningful time off to rest and recharge: 23 days of annual leave (accrued), 15 days of paid sick leave, and paid company holidays. - Fully funded private healthcare for UK employees, with broad provider access, virtual and in‑person care, and strong mental health and serious illness support. - Equity included–we believe builders should share in what they build. - Pension scheme with a total 8% contribution (5% employee, 3% employer) on full earnings. - Free daily breakfast, catered lunch, and snacks in‑office. - Collaboration with top‑tier engineers, researchers, and product experts in AI and robotics. - Freedom to influence the product and own key initiatives.
