Sr. Test Engineer

Senior Test Engineer Contract 40 hours weekly 6-12+ Months The Senior Test Engineer will architect and lead development of integrated hardware and software test platforms that generate Electrical Ground Support Equipment (EGSE) for validating flight hardware. You will define and implement validation strategies, establish test architectures and standards, and ensure flight units meet performance, reliability, and mission requirements throughout development and qualification. Key Responsibilities Lead design and implementation of EGSE systems, including selection of commercial-off-the-shelf (COTS) instruments, design of custom test enclosures, and specification of cabling and connectors. Develop automated test frameworks and scripts to exercise functional, performance, and reliability requirements for Units Under Test (UUTs). Define validation plans, test procedures, and acceptance criteria; execute test campaigns and document results. Interface EGSE hardware with UUTs (typical UUT : SBC with custom analog / digital I / O boards for C&DH in cPCI form factor; EPS boards on custom backplane for power switching and battery / solar management). Collaborate with design, firmware, and systems engineering teams to ensure testability, traceability, and timely defect resolution. Design and verify signal integrity and power delivery solutions to support high-speed interfaces and reliable operation. Support environmental, EMC / EMI, vibration, thermal-vacuum, and flight-acceptance testing as required. Mentor junior engineers and contribute to process improvement and test documentation. Required Qualifications BS in Electrical Engineering (or related) and a minimum of 10 years of relevant experience. Strong software skills : expert-level C and LabVIEW development; scripting experience (Python, Java, or JavaScript). Hands-on experience with traditional and automated test equipment : programmable power supplies, oscilloscopes (high-speed), function / arbitrary waveform generators, frequency counters, logic analyzers, electronic loads, and DAQ systems. Experience with test management and version control tools (e.g., JIRA, TestRail, Git, Perforce). Proven experience designing test hardware, including cable / harness design and integration. Strong troubleshooting and debug skills at system and board level. Familiarity with communication and bus protocols : SpaceWire, Ethernet, USB, SPI, PCI, UART, and SERDES Preferred Qualifications Experience with high-speed signal integrity practices and power distribution design for test systems. Familiarity with VxWorks integration and writing test code for SBC platforms. VHDL experience for FPGA programming and integration with test systems. Prior involvement in environmental, EMC / EMI, or flight-acceptance testing. Experience creating automated regression suites and CI / CD for hardware test flows. Prior work on spaceflight or avionics program
