Senior Mechanical Engineer

Join AnySignal as a Senior Mechanical Engineer, where you will be responsible for the mechanical design of space radios, including enclosures, thermal paths, and structures. This hands-on role involves owning the design process from concept to qualification, performing structural analysis, planning environmental qualification campaigns, and selecting materials and processes suitable for the space environment. You will also establish mechanical engineering practices and mentor other engineers as the team grows.

• Own the mechanical design of space radio enclosures and chassis from concept through to qualification.
• Design the thermal path and run hot- and cold-case analysis for vacuum operation, correlating models against test data.
• Lead mechanical content at design reviews, establish the mechanical engineering practice, and mentor engineers.

• Strong DFM instincts for precision machining and sheet metal, with a track record of working shops effectively
• Direct, hands-on ownership of at least one environmental qualification campaign from test plan through report
• Expert-level CAD (SolidWorks preferred; NX or Creo equivalent) and detailed drawings with GD&T to ASME Y14.5
• Comfortable being the only mechanical engineer in the room: able to make defensible calls on incomplete requirements and explain them to electrical, RF, and program stakeholders
• Structural analysis and FEA experience covering random vibration and shock, with the judgment to know when analysis is sufficient and when to test
• 6+ years of mechanical design experience, including hardware that has flown or been qualified for flight
• Demonstrated ownership of thermal design for vacuum environments, including analysis and correlation to thermal vacuum test results
• Mechanical design specifically for RF payloads or space radios (shielding, gasketing, EMI containment, waveguide and connector interfaces.)
• Proficiency with thermal tools such as Thermal Desktop, Ansys Icepak, or FloTHERM
• Familiarity with radiation environments and shielding mass trades
• Experience with smallsat form factors, ESPA-class payloads, or common bus mechanical interfaces
• Hands-on integration and test experience: builds, harnessing, torque control, and mechanical I&T
• Prior technical leadership or mentorship of other mechanical engineers, formal or informal
