Senior Supplier Development Engineer I/II – Electrical

ABOUT ROCKET LAB Rocket Lab is the end-to-end space company building rockets, spacecraft, and critical subsystems that keep the world connected, protected, expand humanity’s reach to the Moon, Mars, and beyond. We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us. SUPPLY CHAIN Rocket Lab’s Supply Chain team is responsible for the flow of all materials, products, and components through the business. With many of our own products functioning as critical components to our own and our customers’ missions, the Supply Chain team has a direct impact on the success of our rocket and satellite programs. They set up the assembly kits that enables our technicians to put together our Electron rockets, manage inventory, look after shipping and receiving, manage direct and indirect procurement, and inspect and ensure that all of our materials and products are compliant and up to standard. They are the chain that links our teams together, and are critical to our success. SENIOR SUPPLIER DEVELOPMENT ENGINEER I /II - ELECTRICAL Based out of Rocket Lab's headquarters in Long Beach, CA, the Senior Supplier Development Engineer I/II – Electrical is the primary technical owner of the supply base for a broad portfolio of electrical hardware. This role is responsible for leading the end-to-end industrialization of suppliers from source selection and process qualification through NPI, PPAP, and production ramp, thereby ensuring that every supplier can deliver conforming hardware at rate, on cost, and on schedule. This is a hands-on, supplier-facing role requiring deep commodity knowledge across electrical domains, including but not limited to PCBAs (Printed Circuit Board Assemblies), wire harnesses, connectors, sensors, power systems, and electro-mechanical assemblies. The SDE operates proactively at the intersection of design, manufacturing, procurement, and quality. They are the ultimate internal advocate for supply chain manufacturability and capability. WHAT YOU’LL GET TO DO: • Lead end-to-end supplier industrialization for electrical hardware from source selection and process qualification through NPI, PPAP, and rate production ramp. • Partner with procurement and engineering to identify, evaluate, and select suppliers based on process capability, quality systems, and capacity across PCB manufacturing, SMT (Surface Mount Technology), wire harness assembly, connector production, and electro-mechanical integration. • Conduct supplier capability assessments during qualification phases, evaluating tooling maturity, measurement systems, process controls, and workforce qualification against program requirements. • Lead Design for Manufacturability (DFM) reviews with design engineering at the earliest program stage, providing actionable feedback on PCB layout, component selection, trace routing, tolerance stack-ups, and design characteristics that drive cost or quality risk. • Own the APQP process at suppliers, driving completion of all quality planning deliverables — process flow, PFMEA, control plan, MSA/GR&R, and dimensional results — on schedule and to the required standard. • Drive the PPAP program as a production readiness gate; define required submission levels, disposition supplier packages, and ensure process capability (Cpk) is demonstrated on critical and significant characteristics to enable at-rate production. • Lead First Article Inspection (FAI) activities at suppliers and in coordination with internal quality teams; ensure all findings are resolved to closure within project timelines. • Identify systemic performance gaps; own supplier improvement plans and drive measurable progress against quality, cost, delivery, and capacity targets. • Lead root cause and corrective action (RCCA) for supplier quality issues and escapes, applying structured problem-solving methods (8D, 5-Why) and validating that corrective actions are robust and sustained across all applicable parts and production lines. • Apply lean manufacturing and statistical quality tools — including SPC, Cpk trending, and process audits — to drive continuous improvement across the electrical supply base and eliminate sources of recurring defect. **(This position can be hired as a Senior Supplier Development Engineer I or Senior Supplier Development Engineer II)** QUALIFICATIONS YOU’LL BRING AS A SENIOR SUPPLIER DEVELOPMENT ENGINEER I • Minimum 5 years’ experience working in a regulated industry (Aerospace, Medical, Automotive, Industrial, or similar). • Bachelor’s degree in Electrical Engineering, Manufacturing Engineering, or a closely related technical discipline. • Working knowledge of APQP, PPAP, PFMEA, control plans, MSA, and statistical process capability (Cpk/Ppk). • Experience conducting DFM reviews and translating design intent into manufacturing and quality requirements. • Ability to read and interpret engineering drawings, schematics, wiring diagrams, and PCB layouts. QUALIFICATIONS YOU’LL BRING AS A SENIOR SUPPLIER DEVELOPMENT ENGINEER II • Minimum 8 years’ experience working in a regulated industry (Aerospace, Medical, Automotive, Industrial, or similar). • Bachelor’s degree in Electrical Engineering, Manufacturing Engineering, or a closely related technical discipline. • Working knowledge of APQP, PPAP, PFMEA, control plans, MSA, and statistical process capability (Cpk/Ppk). • Experience conducting DFM reviews and translating design intent into manufacturing and quality requirements. • Ability to read and interpret engineering drawings, schematics, wiring diagrams, and PCB layouts. WHAT MAKES A GREAT CANDIDATE: Beyond technical qualifications, we are looking for someone who: • Owns problems all the way to resolution — doesn’t hand off and walk away. • Is proactive at suppliers, not reactive; identifies risks before they become escapes. • Can translate complex engineering requirements into clear, actionable supplier expec
