About Humanoid
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're looking for a Mechanical Engineer Tech Lead to own the mechanical design of our robotic end effectors and lead the technical direction for the mechanical engineering team. You'll lead mechanisms and assemblies end to end — from requirements and concept through CAD, manufacturing drawings, test and evaluation, and production hand-off — while mentoring engineers, driving design reviews, and working closely with electrical, firmware and prototyping teams. This is a hands-on leadership 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
- Lead Technical Direction: Own the mechanical design strategy and architecture for end-effector products, setting technical direction and ensuring consistency and quality across the team.
- Lead Design & Reviews: Lead design reviews and mentor mechanical engineers, raising the technical bar across the team.
- Lead Requirements Development: Work directly with customers and internal stakeholders to gather and define requirements, translating them into clear design specifications.
- Own Mechanical Design: Design and guide 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.
- Own Test & Evaluation: Define and lead test and evaluation plans to validate designs against requirements, including structural, environmental and durability testing.
- Apply DFM/DFA: Apply design-for-manufacture and design-for-assembly principles as designs move from prototype to production.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We're Looking For
- Degree in Mechanical Engineering, Mechatronics, or a related discipline, with 6+ years' experience in mechanical design for robotics, hardware, or complex electromechanical products.
- Proven track record of successfully delivering complex electromechanical or robotic systems from concept through to production.
- Proven experience leading or mentoring mechanical engineers and driving technical direction on complex electromechanical products.
- Experience leading requirements development and test/evaluation planning with customers or stakeholders.
- Proficiency in 3D CAD (Siemens NX preferred), 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.
- Practical understanding of DFM/DFA principles and comfort working iteratively in a high-paced engineering environment.
