Senior Software Engineer - Secure Manufacturing

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.

We're scaling from prototypes to manufacturing, and the process maturity needs to match. This role owns the secure manufacturing pipeline - the procedures, tooling, and controls that take a bare board in an untrusted CM facility and turn it into a cryptographically enrolled, OTA-ready device that our cloud fleet trusts. You'll be the bridge between our secure boot/firmware teams and the cloud control plane, connecting them at the point of manufacture.

• Design the secure manufacturing station - Architect the hardware, software, and network stack (HSM, key injection, AWS Private CA) for factory floor provisioning stations. Integrate the secure boot fuse/flashing flow from our secure boot/firmware team.
• Build the provisioning toolchain - Own the automation pipeline that takes a bare device through identity provisioning, enrollment, firmware flashing, calibration, and functional test.
• Bridge device and cloud identity Enroll every device into a registry with correct credentials for OTA, session heart beating, and deployment tracking.
• Own the End-Of-Line (EOL) test framework - Work with globally distributed teams to define pass/fail criteria for devices leaving the line: sensor calibration, actuator checks, and initial OTA health check.
• Work with contract manufacturers - Translate security requirements into CM-executable procedures; threat-model the factory for key leakage, firmware tampering, and supply chain substitution.
• Maintain chain of custody - Link each physical serial number to its provisioned identity, calibration records, test results, and firmware version at manufacture.
• Collaborate across teams - Work daily with a globally distributed team of firmware, cloud, manufacturing, systems and operational team members.

• 10+ years of experience which includes manufacturing engineering, with a comparable depth of experience developing test tools and frameworks. Plus experience working with networking in a manufacturing environment, and time focused on secure device provisioning and/or secure manufacturing processes. Ideally 3 years at a Staff level or equivalent.
• PKI and device identity - Experience with X.509 certificate life cycles, mTLS, device authentication and attestation, and managed CA services like AWS Private CA.
• AWS infrastructure - S3, IAM, ECS, KMS, CloudHSM and Secrets Manager for secure provisioning workflows.
• EOL test and calibration - Hands-on experience defining manufacturing test frameworks, experience with hardware test fixtures.
• Scripting and automation - Advanced skills in Python or Bash for developing production-grade provisioning tool chains.
• Advanced skills and understanding of Rust, Bazel, Systemd
• Embedded Linux systems - Experience with NVIDIA Jetson Orin/Thor platforms.
• Secure manufacturing design - Ability to design secure processes for untrusted or semi-trusted offshore CMs and air-gapped station design.
• Experience managing quality gates with contract manufacturers
• Hardware root of trust understanding - General understanding of secure boot chains, TPM/Trust Zone, cryptographic key injection, certificate provisioning, and eFuse programming.

• 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 employer match.
• Equity included-we believe builders should share in what they build.
• 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 California, the expected base salary range is $260,000-$320,000 USD per year; your placement in that range depends on how your experience maps to our internal leveling.
