Electro-Mechanical Engineer; Engineering​/Design Team

About Busek

Busek is a leader in innovative space propulsion technologies, specializing in electric and chemical propulsion systems. Our team pioneers advancements in space exploration by developing cutting‑edge propulsion solutions for government and commercial applications.

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.

• 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

• 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 light weighting vs. robustness in spacecraft hardware

The expected salary range for this position is $85,000 - $150,000. Actual compensation will be determined by the candidate’s experience, education, and alignment with organizational needs.
