Summary
T2S Solutions is seeking a Hardware-in-the-Loop (HWIL) Engineer (Power & Mechanical Systems) to support system-level integration, validation, and verification of spacecraft, payload, and ground systems in HWIL environments. This role focuses on power systems, mechanical integration and physical test architectures, bridging detailed hardware knowledge with system-level test objectives. The ideal candidate understands how hardware behavior impacts software, operations, and mission performance.

Key Responsibilities

• Design, configure, and maintain HWIL test architectures that accurately represent operational power and mechanical interfaces.
• Integrate power systems including regulated supplies, load banks, protection devices, harnesses, and distribution hardware into HWIL environments.
• Lead mechanical integration efforts for HWIL setups, including fixture design, mounting strategies, and structural considerations.
• Support hardware bring-up, fault injection, and anomaly investigation during testing.
• Collaborate with systems, software, power, and mechanical engineers to ensure test fidelity and coverage.
• Execute and refine HWIL test procedures, including power cycling, failure modes, and recovery scenarios.
• Monitor and analyze power, thermal, and mechanical performance data during tests.
• Maintain configuration control, documentation, and test records for HWIL assets.
• Apply independent technical judgment to assess system behavior, troubleshoot complex issues, and make informed decisions during HWIL testing.

Required Qualifications

• Bachelors degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or a related technical field
• OR equivalent extensive hands-on experience supporting system-level hardware integration and test.
• Working knowledge of DC power systems, power distribution, protection, and instrumentation.
• Ability to read and reason electrical schematics, wiring diagrams, & mechanical drawings.
• Understanding of system integration and verification concepts
• Strong troubleshooting skills and engineering judgment.
• Ability to work independently while collaborating across engineering disciplines.
• Security clearance or ability to obtain one (if applicable).

Preferred Qualifications

• Experience with HWIL, SIL, flat-sat, iron-bird, or system-level testbeds.
• Familiarity with spacecraft or aerospace hardware and flight-like test environments.
• Exposure to test automation, scripting, or data analysis tools.
• Understanding of thermal control concepts and environmental test preparation.
• Experience supporting verification & validation (V&V) activities for mission-critical systems.

What We Offer

• System-level role at the intersection of hardware, software, and operations
• Opportunity to influence test architecture and mission readiness
• Collaborative engineering environment with high technical standards
• Competitive compensation and comprehensive benefits
