Wire Harness Electrical Engineer II

About Firefly Aerospace

Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24‑hour notice and the first company to achieve a successful Moon landing. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join the team and help fuel its successful trajectory into space.

Role Summary

Electrical Engineers in the Interconnect team develop electrical wiring interconnect systems (EWIS) that distribute power and electrical signals within avionics hardware, instrumentation, and payloads. The role involves working in small, collaborative groups through all stages of component and system design, manufacturing, and testing, taking ownership of projects and collaborating on design, analysis, manufacturing, testing, and final integration of components on launch vehicles and spacecraft.

Responsibilities

• Develop and integrate EWIS designs on launch vehicles and spacecraft.
• Understand and implement industry guidelines and requirements for wire harness development and design.
• Generate schematics, wire diagrams, 3‑D CAD routing, 2‑D assembly drawings, technical documentation, and reports to support flight, qualification, and test‑lab harness assemblies.
• Coordinate requirements and interfaces between engineering disciplines, production, and integration.
• Make development decisions based on technical merit, risk, cost, schedule, and quality assurance.
• Support design reviews by presenting design, analysis, and test results, demonstrating that component design and manufacturing meet flight requirements.
• Partner with engineering and production teams to generate ideas, creative designs, and continuous improvements.
• Tailor aerospace harnessing standards and guidelines to create internal design standards and requirements for cable assemblies, shielding, integration, and vehicle‑level implementation.

Qualifications

• Required: Bachelor of Science (BS) in electrical engineering with 1‑3 years of experience in a related engineering discipline.
• Familiarity with test equipment used to verify harness design and assembly.
• Knowledge of harness design, fabrication, and installation standards such as IPC/WHMA‑A‑620, NASA‑STD‑8739.4, and MSFC‑SPEC‑494.
• Experience selecting connectors, backshells, wires, and other harness components.
• Understanding of electrical grounding requirements and implementation of system‑level grounding via wire harness design.
• Effective verbal and written communication skills.
• Ability to work well in a team, be proactive, and execute with minimal guidance.
• Detail‑oriented and able to manage multiple concurrent tasks.
• Desired: Bachelor of Science in electrical engineering with 3+ years of experience, or Master of Science with 1+ year of experience.
• Proven ability to generate end‑to‑end interconnect schematics, wire diagrams, and harness assembly drawings.
• Experience with 3‑D CAD design, 2‑D drafting, and PLM software such as Siemens NX, Capital, and Teamcenter.
• Hands‑on experience with harness assembly and shielding integration.
• Understanding of basic subsystems of a space‑rated vehicle and avionics interfaces.
• Experience with instrumentation and high‑speed digital communication protocols.
• Hands‑on experience integrating electronics and harnessing in airborne vehicles.
• Knowledge of range safety, flight termination, and tracking system requirements such as RCC 319, RCC 324, and AFSPCMAN 91‑710.

Benefits

• Generous health, dental, and vision plans with low deductibles.
• Parental leave.
• Educational reimbursement.
• Short‑term disability.
• Flexible PTO options.
