Senior Supplier Development Engineer I/II – Electrical

Rocket Lab Corporation • Long Beach, CA

3d • Onsite

About The Position

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.

Requirements

• 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.

Nice To Haves

• 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 expectations.
• Builds genuine working relationships with supplier technical teams and earns trust through competence.
• Communicates with clarity and urgency across internal engineering, procurement, quality, and program management.
• Thrives in a fast-paced, resource-constrained environment and makes high-quality decisions under schedule pressure.
• Brings intellectual curiosity about manufacturing — enjoys spending time on the shop floor understanding how things are made.

Responsibilities

• 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.

Benefits

• Employees may also receive company equity and access to a robust benefits package including: top tier medical HMO, PPO & a 100% company-sponsored medical HSA plan option, dental and vision coverage, 3 weeks paid vacation and 5 days sick leave per year, 11 paid holidays per year, flexible spending and dependent care savings accounts, paid parental leave, disability insurance, life insurance, and access to a 401(k) retirement plan with company match.
• Other perks include: Discounted employee stock purchase program, subsidized EV charging stations, onsite gym, food and drinks, and other discounts.
