Manufacturing Process Engineer

As a Manufacturing Process Engineer, you will turn complex electro-mechanical products into safe, reliable, repeatable production lines for Zipline’s aircraft, docks, and logistics hardware. You will own assigned final assembly and feeder sub-assembly lines from process definition and tooling through validation, production release, and sustainment.

This work connects aerospace-quality manufacturing with reliable field operations and rapid production growth. You will help scale output from tens to thousands of units per week over the next 1–3 years while meeting safety and reliability expectations. Your initial priority is to bring a complex electro-mechanical sub-assembly in-house and validate its production line within months.

This opening sits within our manufacturing engineering team; the exact focus will reflect your strengths and the team’s needs. Rare travel between sites may be required during ramp and sustainment. Nights or weekends may be needed to support critical production ramps or outages.

• Own assigned assembly lines and feeder subassemblies from process definition, tooling, and pilot builds through validation, release, and sustainment.
• Design, procure, install, and commission fixtures, gauges, tooling, workstations, and ergonomic operator flows.
• Define and validate assembly sequences, PFMEAs, control plans, SPC, capability studies, first-article processes, and release criteria.
• Investigate production issues and escapes, validate root causes, and implement corrective and preventive actions.
• Improve first-pass yield, throughput, takt time, equipment reliability, downtime, and cost of poor quality against agreed targets.
• Lead design-for-manufacturing decisions that balance assembly time, inspection, cost, safety, and field reliability.
• Create SOPs, work instructions, and training materials; train and qualify technicians and line leads.
• Coordinate capacity, layouts, equipment, and readiness with Design Engineering, Quality, Supply Chain, Maintenance, and Operations; deliver a validated pilot line and stabilize production.

• 2+ years of hands-on manufacturing engineering experience designing, building, and sustaining assembly lines for complex electro-mechanical products, with a track record of scaling volume by an order of magnitude.
• 5–7 years of relevant experience preferred.
• A BS in Mechanical Engineering or a related field is required; an advanced degree is a plus.
• Practical mastery of PFMEA, control plans, SPC, capability analysis (Cp/Cpk), first-article processes, and production validation.
• Experience designing and validating custom fixtures, jigs, and tooling, with proficiency in 3D CAD; Siemens NX is preferred.
• Experience with MES/ERP and statistical tools such as Minitab, JMP, or Excel to measure and improve yield and process capability.
• Demonstrated cross-functional DFM decisions that balance cost, manufacturability, safety, and field reliability.
• End-to-end project ownership with minimal oversight, including planning, budgeting, procurement, commissioning, and sustaining production lines.
• A hands-on approach to manufacturing, careful attention to process details, clear communication of tradeoffs under schedule pressure, and a commitment to safety and quality.
• Accountability for ramp milestones and agreed yield, throughput, and cost targets, with a structured approach to preventing production escapes and meeting release criteria.

• Deliver a validated pilot line for the assigned electro-mechanical assembly, with documented process controls and demonstrated Cp/Cpk targets.
• Achieve first-pass yield and throughput targets established at project start and reduce key PFMEA failure modes through validated process improvements.
• Meet the established production-release window and stabilize yield and throughput through cross-functional execution and sustained corrective actions.

The starting cash range for this role is $104,000 - $170,000. Please note that this is a target, starting cash range for a candidate who meets the minimum qualifications for this role. We are always open to negotiation.
