Senior Hardware Test Engineer Job at Karmanplus in Broomfield

Position

Senior Hardware Test Engineer

Location

Broomfield, CO

Position Type: Full-time, On-site

Mission

High Frontier – Validate the Hardware That Powers Deep Space Exploration

Join our mission to kickstart the space resource economy! With our prototype mission “High Frontiers” targeted to launch early 2027, we are looking for hands-on electrical engineers to develop the avionics that will power the first commercial asteroid mining satellites.

Every team member at Karman+ contributes across disciplines. You’ll play a hands-on role in building a deep space mission, applying your technical expertise while mentoring newer engineers. Your units will operate millions of miles from Earth, powering the technology that makes space resource extraction possible.

What it takes to be successful in this role

As a Hardware Test Engineer at Karman+, you’ll help ensure our boards and boxes are fully validated prior to system integration. Working closely with design engineers you will translate requirements into tests, evaluate test gaps and propose solutions to fill them, and work closely with all team members to ensure hardware excellence.

Expect to perform a mix of tasks including test equipment scripting using python, test procedure drafting and execution, and test rack and fixture development. When needed you will design your own PCBAs, or select an off the shelf solution, applying the proper solution where needed.

What You’ll Do

• Own box-level validation of in-house designs prior to handoff to the Assembly, Integration & Test (AI&T) team for system integration.
• Ensure full test coverage by collaborating with design engineers—translate requirements into tests, identify gaps, and propose solutions.
• Develop and maintain automated test tools—script test equipment, build racks, or design simple interface boards and fixtures as needed.
• Lead validation efforts for multiple avionics boxes and mentor junior test engineers as the team grows.
• Author test plans, procedures, and reports to ensure traceability and compliance with mission requirements.

What You Bring

• 5+ years of experience in hardware test with demonstrated hands-on experience.
• Strong understanding of fundamental electrical engineering concepts and ability to apply them to practical problems.
• Ability to develop and execute unit-level test plans from scratch. Experience with unit-level thermal vacuum, vibration, and thermal testing.
• Hands-on experience using and scripting standard lab equipment including oscilloscopes, multimeters, power supplies, and function generators.
• Proficiency with Python or an equivalent scripting language for test equipment automation.
• Strong debugging and troubleshooting skills, with the ability to systematically isolate and resolve circuit issues.
• Ability to design simple test fixtures or interface boards, and experience with tools such as LTSpice for simulation prior to fabrication.
• Experience leading technical discussions and design reviews.
• Excellent written and verbal communication skills for documentation and cross-functional collaboration.
• Demonstrated ability to work across disciplines with a diverse group of engineers.

Technical Environment/Tools

The following tools are used by our team

• Scientific Computing: Python, Maxima
• Simulation: LTSpice, Simetrix
• Scripting: Python
• Operating Systems: Primarily Windows, some *nix for code development

Requirements

• Foundational experience in design and hardware for spacecraft or aerospace.
• BS or MS in engineering, aerospace engineering, or related technical field.
