Our customer is our own operations team, which puts engineering and the field about as close together as they can get. We push design changes to flying hardware roughly once a week while scaling production at the same time.\nToday every part of that loop is owned by full-stack engineers who each design a part, own its tooling, and tweak it based on field performance. That has worked so far, but manufacturing throughput and tooling maintenance have grown into a full-time load that can no longer share a desk with design iteration. This role exists to take that load.\nManufacturing and Production turns engineering designs into repeatable, high-quality production. We build mechatronic hardware assemblies - PCBA, electronic sensors, ballast, and an adjustable inflatable balloon.\nBoards arrive populated from our suppliers. On our floor, we assemble the PCBAs into the electronics assembly, test it, and then build up the mechanical hardware, ballast, and balloon around it. The work is manual to semi-automated, and it has to hold together while the designs underneath it keep changing.\nWe are running about 1,000 units a month and doubling roughly every six months. Most hardware teams get design lock before volume. We don't, and the manufacturing system has to work anyway.\nOwn manufacturing engineering for parts as they come off the design team.\nYou will take on process, tooling, and production responsibility so design engineers can stay on design and bring-up. You will decide which parts of a design are stable enough to tool up and document, and which need to stay flexible - and you will be able to explain why. Above all, you will design the processes that turn a weekly-changing design into a build that runs the same way every time.\nThis is a hands-on individual contributor role reporting to the Head of Manufacturing.\nKey Outcomes\nProduction processes that are designed, documented, and stable enough for the floor to run without the design engineer standing next to them\n\nDFM feedback delivered early and often, so manufacturability is settled before a design hardens - and design changes that reach the floor without breaking it\n\nClean design-to-manufacturing handoffs, including for parts not yet at full design lock, with judgment applied to what gets systematized and what stays flexible\n\nFunctional, end-to-end test fixtures and protocols that catch defects at the electronics assembly stage rather than at final build\n\nJigs, fixtures, and assembly aids that raise throughput and repeatability across electronics integration and mechanical assembly\n\nEquipment and workstations owned from first request through ramp - specification, sourcing, vendor buy-off, installation, and handoff to production\n\nStation layout, line balance, and capacity modeled ahead of demand, so the floor is ready for the next doubling before it arrives\n\nA manufacturing backbone built from the ground up - work instructions, revision and change practices, production documentation - extending the lightweight in-house system already in place\n\nCycle time and first-pass yield that hold as volume doubles\n\nCore Responsibilities\nProduction processes that are designed, documented, and stable enough for the floor to run without the design engineer standing next to them\n\nDFM feedback delivered early and often, so manufacturability is settled before a design hardens - and design changes that reach the floor without breaking it\n\nClean design-to-manufacturing handoffs, including for parts not yet at full design lock, with judgment applied to what gets systematized and what stays flexible\n\nFunctional, end-to-end test fixtures and protocols that catch defects at the electronics assembly stage rather than at final build\n\nJigs, fixtures, and assembly aids that raise throughput and repeatability across electronics integration and mechanical assembly\n\nEquipment and workstations owned from first request through ramp - specification, sourcing, vendor buy-off, installation, and handoff to production\n\nStation layout, line balance, and capacity modeled ahead of demand, so the floor is ready for the next doubling before it arrives\n\nA manufacturing backbone built from the ground up - work instructions, revision and change practices, production documentation - extending the lightweight in-house system already in place\n\nCycle time and first-pass yield that hold as volume doubles\n\nSkills & Qualifications\nRequired\nBachelor's degree in Mechanical, Manufacturing, Mechatronics, or a related engineering field\n\n3+ years in manufacturing engineering, with a track record of launching assembly line processes, equipment, and/or new products\n\nDemonstrated process development experience - processes you designed, documented, and put into production\n\nStrong DFM fundamentals, applied in direct partnership with design engineering\n\nExperience taking electromechanical or mechatronic products from prototype into production, including electronics assembly and functional test\n\nExperience designing functional test fixtures and test protocols\n\nProficiency in CAD for fixture, tooling, and workstation design\n\nAble to work on-site in Redwood Shores\n\nNice to have\nHave run electronics assembly integration and in-line functional test\n\nHave worked in high-mix, rapid-iteration environments where the design was still moving\n\nKnow standard process documentation practice - PFMEA, control plans, DOE, SPC\n\nAre strong on GD&T and tolerance analysis for mechanical parts\n\nHave specified, sourced, and bought off production equipment with outside vendors\n\nHave managed suppliers and incoming quality for outsourced parts (3D-printed, laser-cut, PCB/PCBA)\n\nHave stood up quality, yield, inspection, or documentation systems from scratch\n\nHave applied Lean or structured continuous improvement to a real line\n\nBenefits\n401(k)\n\nHealth, dental, and vision insurance 100% covered\n\nUnlimited PTO\n\nEquity\n\nOffice food and beverages (minimum 2x catered lunches and dinners a week)\n\nSalary\n$120,000 - $200,000 plus equity.
