Full Job Posting

What You'Ll Build

  • Define, develop, and document manufacturing processes for electromechanical hardware assemblies and products from NPI through volume production.
  • Own the DFM (Design for Manufacturability) and DFT (Design for Test) review process, partnering with hardware and firmware teams to ensure designs are production-ready before each build phase.
  • Oversee tooling and drive tooling qualifications with the CM and suppliers.
  • Create and maintain manufacturing documentation, including BOMs, work instructions, traveler documents, test specifications, and process control plans.
  • Lead process qualification activities. Ensure manufacturing processes are documented, repeatable, and in control before production transitions.
  • Support cost reduction through process optimization, cycle time reduction, and make-versus-buy analysis.
  • Work closely with firmware engineers to align manufacturing test fixtures, programming stations, and functional test procedures with firmware release schedules.
  • Flag integration risks between firmware milestones and build readiness. Drive resolution across engineering and operations before they become production issues.
  • Develop and maintain end-of-line test and functional test procedures, including ICT, functional verification, and firmware flashing and validation steps.
  • Manage the technical manufacturing relationship with our CM. Serve as the primary manufacturing engineering interface for process questions, quality issues, and build readiness reviews.
  • Own the manufacturing impact assessment and implementation of ECRs (Engineering Change Requests) and ECOs (Engineering Change Orders), working across the CM, supply chain partners, and Engineering.
  • Participate in and own manufacturing metrics and improvement strategies within QBRs.
  • Drive yield improvement initiatives. Investigate production failures through structured root cause analysis and work with suppliers, Engineering, and Quality to implement corrective actions.
  • Establish and track manufacturing KPIs, including first-pass yield, cycle time, scrap rate, and test escape rate.
  • Build the quality and yield feedback loop that gets sharper with every build.

What We'Re Looking For

  • 10+ years of manufacturing engineering experience on hardware products, ideally at a company that scaled from NPI through volume production.
  • Strong background in high-volume electromechanical assembly, PCBA, injection molding, casting, and system-level integration.
  • Experience developing and owning manufacturing test strategies, including ICT, functional test, and firmware programming and validation. This includes the design and coordination of test fixtures.
  • Demonstrated experience working cross-functionally with firmware and software engineering on test fixture requirements and programming station design.
  • Hands-on contract manufacturing management experience, including overseas CMs.
  • Experience with DFM and DFT reviews and driving design changes to improve manufacturability and testability.
  • Proficiency reading and working with electrical schematics, PCB layouts, BOMs, and mechanical drawings.
  • Experience leading builds from prototype through production ramp.
  • Strong quality engineering background, including PFMEA, control plans, SPC, 8D and root cause analysis, and IPC standards.
  • Experience with wearables, consumer electronics, or ruggedized hardware programs.
  • Familiarity with contract manufacturers in Taiwan, mainland China, or Southeast Asia.
  • Ability to generate clear and concise updates to all levels of internal and external stakeholders, including at the executive level.
  • Detail-oriented, self-motivated, and able to respond quickly to a fast-moving and ever-changing environment.
  • Proficiency with ERP systems for BOM management and manufacturing order tracking.
  • Proficiency with PLM systems (Arena, Propel, or similar).
  • Experience with battery pack and optical subassemblies.
  • Prior experience as an early manufacturing hire at a hardware startup that scaled from early volumes to full production. You've been through the zero-to-scale journey and know what breaks first.
  • Mandarin or Vietnamese language proficiency.
  • Experience shipping products with meaningful firmware complexity, where hardware and firmware release cycles had to stay in tight lockstep.

What Success Looks Like

  • First 60 days. You know our product cold, including the BOM, the test architecture, our current CM relationship, and our firmware release cadence. You've built relationships with our critical CM contacts and identified the top three manufacturing risks we need to address before our next production ramp.
  • First 6 months. You've driven measurable improvements in first-pass yield and cycle time. Our manufacturing documentation is complete, current, and trusted by both Engineering and the CM. Our test and firmware integration is running smoothly through release cycles without last-minute fire drills.
  • First 12 months. You're the internal authority on how Ironsite manufactures. Our processes are documented, our yields are strong, and our CM relationship is healthy. When we scale to hundreds of thousands of units, we're set up to do it because of the systems you put in place.

• San Francisco Bay Area (on-site)

  • Base salary: $225k-$250k per year, commensurate with experience
  • Significant early-stage equity
  • Full benefits including health, dental, vision, and 401(k) with 6% match
  • Daily catered breakfast and lunch
  • Office in San Francisco, next to Oracle Park and the Caltrain
