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 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further. ### About the Role We're looking for a Senior Mechanical Engineer to design and iterate end effectors for our robots and the human-worn devices operators use to interface with them. You'll own mechanisms and assemblies end to end — from concept and CAD through to manufacturing drawings and production hand-off — working closely with electrical, firmware and prototyping engineers. This is a hands-on role where you'll balance rapid iteration with rigorous engineering fundamentals, in a high-paced environment where designs evolve quickly and priorities shift fast. What you'll do Own Mechanical Design: Design mechanical components, assemblies and enclosures end-to-end using 3D CAD (Siemens NX), from concept through to manufacturing-ready drawings. Integrate Mechatronic Systems: Integrate cameras, sensors, PCBAs and other mechatronic devices into mechanical assemblies, working closely with electrical and firmware engineers. Balance Design Trade-offs: Weigh weight, durability, ergonomics and manufacturability requirements to arrive at the right solution for each design. Select Materials & Processes: Choose appropriate materials and manufacturing processes, including 3D printing, CNC machining, sheet metal and injection moulding. Prototype & Iterate: Rapidly prototype and refine designs based on testing, trials and feedback from engineering and customers. Engage with Customers: Work directly with customers to develop requirements and test plans that shape design decisions. Apply DFM/DFA: Apply design-for-manufacture and design-for-assembly principles as designs move from prototype to production. Support Validation: Plan and support mechanical validation and testing, including structural, environmental and durability testing. What we're looking for Degree in Mechanical Engineering, Mechatronics, or a related discipline, with 5+ years' experience in mechanical design for robotics, hardware, or complex electromechanical products. Proficiency in 3D CAD (Siemens NX preferred, or strong willingness to learn), including GD&T and tolerance stack-up analysis. Experience designing for 3D printing, CNC machining, injection moulding and sheet metal, with hands-on rapid prototyping experience. Experience integrating electromechanical assemblies — cameras, sensors, PCBAs, connectors, cable routing and enclosures. Experience working with customers or stakeholders to develop requirements and test plans. Practical understanding of DFM/DFA principles and comfort working iteratively in a high-paced engineering environment. Nice to have FEA/simulation experience for stress, fatigue or thermal analysis Experience designing wearable or human-worn hardware Exposure to small-batch or production manufacturing hand-off ### What We Offer Competitive equity: stock options with meaningful upside as we scale. 30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas–New Year shutdown). Private healthcare, including virtual and in-person care. Pension scheme with 8% total contribution (5% employee, 3% employer) on full earnings. Free daily breakfast, catered lunch, and snacks in-office. Work at the frontier - collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics. Real ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one. --- Data: alder (https://alderhq.app).
