Our Littleton, CO team uses engineering talent to design and deploy cutting-edge power distribution, embedded monitoring and control, power conversion, and camera-based solutions, revolutionizing space flight. Join us to expand humanity’s presence in space.

About the role

Redwire Space Missions, LLC in Littleton, CO has an exciting opportunity for a Contractor – Electronics Test Engineer (all senior levels) for up to 6 months, with potential follow-on work. We seek an experienced Electronics Test Engineer to lead the bring-up, functional, and design verification testing of spacecraft power electronics boards. This highly hands-on role requires a methodical troubleshooter who can work beyond strict test procedures, identify root causes of anomalies, and collaborate closely with design engineers. This position focuses exclusively on board-level testing.

Responsibilities

• Perform board-level bring-up, functional, and design verification testing on spacecraft power electronics boards.
• Methodically troubleshoot issues using schematics, layouts, component data, and design intent.
• Analyze anomalies and drive root-cause identification (component failures, layout concerns, firmware interface issues, power sequencing errors, etc.).
• Use bench instrumentation to validate power rails, heater drivers, analog front ends, digital interfaces, and protection circuits.
• Execute tests in situations where procedures are evolving; develop and refine test steps as required.
• Document findings clearly and provide actionable feedback to design engineering teams.
• Support failure analysis, corrective actions, and re-testing as needed.
• Collaborate with software, systems, manufacturing, and other functional teams to ensure design maturity and production readiness.

Requirements

• BS Degree in Electrical Engineering.
• Minimum 8+ years of hands-on experience testing and troubleshooting complex electronic PCBs.
• Proven ability to isolate and diagnose hardware issues down to component-level root cause.
• Direct experience testing power electronics (e.g., DC/DC converters, power sequencing, protection circuits).
• Strong familiarity with standard bench instrumentation (oscilloscopes, SMUs, electronic loads, DMMs, power analyzers).
• Comfortable working onsite in a lab environment with flight hardware.
• Experience working with SMPS, Load Switches, Op-Amps, and Comparators.
• Experience with FPGA, microcontroller, or microprocessor-based control and telemetry interfaces.
• Ability to travel as needed, up to 10% on average.

Desired Skills

• Master’s degree in Electrical Engineering.
• Strong proficiency interpreting and working directly from schematics and board layouts.
• Ability to work with incomplete test documentation and adapt procedures during bring-up.
• Experience testing or bringing up spacecraft power modules (PCU, PDU, BMS/BCPM, heater drivers) or similar flight-class power systems.
• Demonstrated expertise troubleshooting high-reliability power electronics, including nuanced failure modes (e.g., control-loop instability, sequencing transients, marginal component derating).
• Experience diagnosing complex mixed-signal interactions, such as analog front-end drift, ADC sampling artifacts, logic-level timing collisions, or firmware handshake issues.
• Ability to assess and validate protection circuitry behavior under edge cases: current-limit foldback, soft-start anomalies, OV/UV trigger thresholds, fault-latching logic.
• Strong capability in identifying latent design defects (not just overt failures), including component tolerance stacking, thermal coupling issues, or layout-induced noise paths.
• Knowledge of EMI/EMC design practices and grounding/shielding techniques.
• Experience methodically troubleshooting and resolving issues and anomalies in accordance with root cause corrective action (RCCA) process.
• Experience working cross-functionally with design engineering to refine schematics, update component selections, or propose design corrections based on board-level findings.
• Excellent written and verbal communication skills with the ability to generate clear design documentation and review materials.
• Ability to distill complex technical data into digestible presentation material for customers and executive leadership.
