Senior ECAD Librarian at Humanoid (US Boston, MA)Senior ECAD Librarian

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 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further.

Humanoid's Core Platform Electrical team designs and releases the PCBs that power our humanoid robots — from sensor interface boards to power distribution and compute carrier cards. As we scale from prototype to production, keeping our Altium component library clean, consistent, and traceable has become mission-critical to design velocity and quality. We're looking for an ECAD Librarian to own and grow our Altium Designer component library. You'll be the go-to owner for schematic symbols, footprints, and component data across our Boston, Vancouver and London EE teams, ensuring every part that goes into a design is accurate, manufacturable, and properly tracked from draft through production. This is a foundational role for a small, fast-moving hardware organization — your work directly reduces respin risk, rework, and time lost to bad footprints or duplicate parts.

• Own the Altium component library. Create, validate, and maintain schematic symbols, PCB footprints, and 3D models for new components requested by EE designers in Boston and London.
• Enforce library standards. Apply and evolve our standardized approach to symbol sizing, footprint conventions, reference designator (REFDES) schemes, and naming conventions for passives, ICs, and mechanical library items (per our library rules and guidance documentation).
• Manage the component lifecycle. Administer part status workflow (Draft → Preliminary → Production) in Altium, ensuring only vetted, verified parts are promoted for use in active designs.
• Component data integrity. Verify manufacturer part numbers, approved alternates, and Part Choices are correctly attached to library parts; keep footprint/pinout data accurate against datasheets to prevent field errors (e.g., mis-pinned footprints making it into fabricated boards).
• Traceability & "Where-Used." Support where-used traceability for components, symbols, and footprints so the team can quickly identify PCB exposure when an issue is found with a given part or footprint.
• Cross-functional support. Work closely with EE designers across the #chapter-ee community to add, retire, and validate components on request, and communicate library changes that may affect in-flight designs.
• PLM/ERP alignment. Support the ongoing effort to integrate Altium component data with our broader PLM system (Teamcenter) and part numbering scheme, working with the EE and supply chain teams.
• Bulk library cleanup. Partner with engineering on periodic bulk edits and standardization passes across the existing library to reduce duplication and inconsistency.
• Documentation. Keep library rules, statuses, and conventions current in Confluence so the standards are discoverable and followed consistently by all designers.

• Hands-on experience with Altium Designer, including schematic library and PCB footprint creation (Altium 365 / Managed Components experience a plus).
• Strong attention to detail — comfortable cross-referencing datasheets, verifying pin counts, pad geometry, and package dimensions before a part goes into a design.
• Familiarity with component lifecycle/PLM concepts (draft/preliminary/released states, where-used traceability) and how they connect to manufacturing quality.
• Understanding of standard component conventions: reference designator schemes, tolerances (e.g., 1% resistors, 10% capacitors), automotive/AEC-Q200 grading where relevant, and approved manufacturer/supplier alternates.
• Comfortable working across a distributed EE team (Boston and London) and prioritizing incoming library requests.
• Bonus: experience with Teamcenter or another PLM system, or prior exposure to integrating ECAD libraries with enterprise PLM/ERP.
• Bonus: experience in a hardware startup or fast-scaling engineering org where library hygiene had to be built from the ground up.

• Comprehensive health coverage for US‑based employees, including fully paid medical, dental, and vision insurance, with virtual care and employee assistance resources.
• Meaningful time off to rest and recharge: 23 days of PTO (accrued), separate sick leave, and paid company holidays.
• 401(k) retirement plan with 4% employer match.
• Competitive equity: stock options with meaningful upside as we scale.
• Free daily catered lunch, snacks, and drinks in‑office.
• Collaboration with top‑tier engineers, researchers, and product experts in AI and robotics.
• Freedom to influence the product and own key initiatives.

For this role in Massachusetts, the expected base salary range is $100K–$140K USD per year; your placement in that range depends on how your experience maps to our internal leveling.
