Electro-Mechanical Engineer (Engineering / Design Team)

Location: Natick, MA

As a senior-level mechanical engineer to join the Design & Analysis Team, you will have primary responsibility for PPU chassis design. This role requires full ownership of the PPU mechanical system: chassis, covers, slices, interfaces, fasteners, and sustaining engineering. The engineer must integrate electrical, thermal, structural, and manufacturing constraints into robust, flight-ready designs. In addition to their own design work, this person will also mentor and provide oversight to junior engineers working on similar technology.

How you will make an impact:

• Chassis & Packaging Ownership – Responsible for chassis architecture (covers, slices, interfaces), with strong grounding in DFM/DFA and material properties.
• Electrical Coordination – Be able to collaborate daily with electrical engineers and translate board requirements into mechanical solutions.
• Thermal Design (Space Environment) - We are an aerospace company.
• Bring an understanding and knowledge of conduction and radiation as the primary modes of thermal transfer in spacecraft environments.
• Experience with thermal conduction paths through chassis into heat pipes/spacecraft panels.
• Knowledge of thermal vias as a primary method of CCA heat extraction, and how to interface them mechanically (gap pads, preload, flatness).
• Familiarity with surface finishes, coatings, and emissivity for thermal radiation management.

• Mechanical Analysis Skills – Steinberg analysis for CCAs, shock and vibration survivability, and spacecraft-specific load cases.
• Sustaining Engineering – Experience with non-conformances (NCR/MRB), ECO implementation, and supporting hardware through production.
• Cross-Functional Collaboration – Effective at working with design, analysis, manufacturing, supply chain, and QA to deliver flight-ready hardware.
• Proficiency with GD&T and compliance with ASME Y14.5 drawing standards.
• · Experience producing cavity sketch layouts and specialized mechanical drawings for PPU packaging.

Nice to Haves:

· Knowledge of spacecraft radiation effects on mechanical/electrical interfaces (trace degradation, shielding).

· Familiarity with heat pipe integration into panel-level designs.

· Background with NASA, ECSS, or MIL-STD design standards.

· Experience balancing lightweighting vs. robustness in spacecraft hardware.
