Senior Validation 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 an experienced Validation Engineer to own the in-house test infrastructure that validates our humanoid robots. This is a foundational, hands-on role: you will not just run tests; you will build the rigs that run them.

You will be the engineer who walks into a conversation with a systems owner, leaves with a clear picture of what needs to be tested and what equipment that requires, then turns around and gets it built — sourcing parts, designing mechanical and electrical components, and commissioning the rigs on the validation floor.

What You'll Do

• 1. Test Rig & Jig Arrangement (Core Focus)

  • In-House Validation Rigs: Lead the arrangement of test rigs and jigs for in-house validation of subsystems and full robots. You decide what gets built, what gets bought, and how they integrate into the validation workflow.

  • Test Rig Development: Design and build custom mechanical jigs and fixtures to stress-test specific sub-systems (e.g., repeating arm movements, actuator loading, cable flexing, end-effector cycling).

  • Commissioning: Bring each rig from a CAD model to a working setup on the floor — wiring, instrumentation, data capture, and first article validation.

  2. Scope & Requirements Definition

  • Systems Owners Engagement: Work directly with the owners of each robot subsystem (actuators, manipulators, perception, power, etc.) to define what needs to be validated, at what coverage, and with what fidelity.

  • Supportive Test Equipment Specs: Translate validation needs into concrete requirements for supportive equipment — PCB test beds, mechanical fixtures, instrumentation, data loggers — and decide what we build vs. buy.

  • Validation Plans: Convert the resulting scope into validation plans that align with the product release roadmap.

  3. Procurement & Supplier Coordination

  • Parts Sourcing: Identify, evaluate, and order parts and equipment from external suppliers — from standard COTS components to custom fixtures.

  • Vendor Management: Manage relationships with suppliers of test equipment and custom fabricated parts; negotiate lead times that align with our test schedule.

  • Cost & Lead Time: Own the budget and lead-time picture for the validation infrastructure you build.

  4. Mechanical & Electrical Rig Design

  • Mechanical Design: Design mechanical components of test rigs in CAD — fixtures, frames, motion stages, mounts — to a quality where they can be fabricated and assembled without rework.

  • Electrical Design: Design the electrical side of the rigs — wiring, power distribution, sensor integration, basic control electronics — including schematics and BOMs.

  • DfX for Test Rigs: Apply manufacturability and reliability principles to your own rigs, so they remain trustworthy for the months or years they will be in service.

  5. Reliability & Compliance Support

  • Life-Cycle & Endurance Testing: Support long-term endurance and life-cycle tests (HALT/HASS, MTBF) where the rigs you build are the enabling infrastructure.

  • Regulatory Awareness: Understand what each validation activity contributes to certification (EMC, environmental, safety) and design rigs that produce certification-grade data where required.

  Qualifications

  Must-Have:

  • Experience: 5+ years in hardware validation, test engineering, or test equipment development, preferably in robotics, automotive, or aerospace.

  • Rig Design: Proven hands-on experience designing and building test rigs and fixtures — from concept through commissioning.

  • Mechanical Design: Strong CAD skills (SolidWorks, Fusion, NX, or similar) and a working knowledge of mechanical components (linear stages, bearings, motors, actuators) and basic machining/fabrication processes.

  • Electrical Design: Comfortable designing the electrical side of a rig — schematics, wiring harnesses, power distribution, sensor integration. You can spec and wire up a DAQ from scratch.

  • Cross-Functional: Track record of working closely with system/component owners to translate validation needs into testable infrastructure.

  • Procurement: Experience sourcing parts and equipment from external suppliers, including custom fabrication.

  Nice-to-Have:

  • Data Acquisition: Proficiency with DAQ systems (LabVIEW, National Instruments, Dewesoft) and common sensors (accelerometers, thermocouples, load cells, encoders).

  • Regulatory Knowledge: Familiarity with certification processes (UL, CE, FCC) and standards (IEC 61000 for EMC, IEC 60068 for Environmental).

  • Robotics: Prior experience validating robotic systems (manipulators, legged platforms, AMRs).

  • Python: For automating data collection and basic test orchestration.

  • PCB Test Beds: Hands-on experience designing or commissioning PCB-level test fixtures.

  The Equipment You Will Build & Manage

  • Custom Mechanical Endurance Rigs (arm cyclers, joint loaders, cable flex testers)

  • PCB Test Beds and Functional Test Fixtures

  • Sensor & Actuator Characterization Stations

  • Battery and Power Test Setups

  • Data Acquisition and Logging Infrastructure

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.
