• Lead mechanical integration and verification of high-reliability payload assemblies, subassemblies, and flight hardware
• Execute mechanical build tasks, precision alignments, torque/tolerance verification, and hardware fit checks
• Coordinate environmental testing (vibration, shock, TVAC) and assess mechanical performance throughout test campaigns
• Identify mechanical integration risks, develop mitigation plans, and drive rapid issue resolution
• Work closely with Optics, Electrical, Systems, and AIT teams to ensure structurally and thermally compliant integrations
• Refine mechanical procedures, integration tooling, and test setups to increase efficiency and hardware consistency
• Support readiness reviews, data packages, configuration audits, and delivery milestones
• Drive continuous improvements in build processes, mechanical verification approaches, and interface control

YOU’LL BRING THESE QUALIFICATIONS AS SENIOR ENGINEER II:

• Active U.S. Government Security Clearance with TS/SCI eligibility
• Bachelor’s degree in Mechanical or Aerospace Engineering; advanced degree preferred
• 8+ years hands-on experience integrating and testing mechanical hardware for space or high-reliability systems

• Working knowledge of GD&T, tolerancing, precision mechanical alignment, and hardware inspection
• Experience with environmental test preparation and post-test mechanical inspection

YOU’LL BRING THESE QUALIFICATIONS AS PRINCIPAL ENGINEER:

• Active U.S. Government Security Clearance with TS/SCI eligibility
• Bachelor’s degree in Mechanical or Aerospace Engineering; advanced degree preferred
• 12+ years hands-on experience integrating and testing mechanical hardware for space or high-reliability systems
• Strong experience with CAD tools (SolidWorks) for interface interpretation and integration planning
• Working knowledge of GD&T, tolerancing, precision mechanical alignment, and hardware inspection
• Experience with environmental test preparation and post-test mechanical inspection

THESE QUALIFICATIONS WOULD BE NICE TO HAVE:

• Experience integrating EO/IR payloads or opto-mechanical assemblies
• Familiarity with contamination control, materials compatibility, adhesives, and fastener systems
• Experience developing mechanical integration procedures or test plans
• Prior experience supporting hardware qualification or acceptance testing

ADDITIONAL REQUIREMENTS:

• Specific vision abilities required by this job include close vision, distance vision, peripheral vision, depth perception, and the ability to focus
• Regularly required to sit, use hands and fingers, operate computer keyboard and controls, and communicate verbally and in writing
• Must be physically able to commute to buildings
• Occasional exposure to dust, fumes and moderate levels of noise
• Ability to regularly perform hands-on hardware integration in lab/cleanroom environments
• Ability to support extended or off-shift work during key test milestones

WHAT TO EXPECT

We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work and out-pace. We pride ourselves on having each other’s backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.
