Senior Avionics Mechanical Engineer

Any Signal is developing the next generation of RF products and services for some of the most demanding space and defense missions. We’re building a flexible, high-performance platform that’s easy to deploy, monitor, and scale, enabling customers to bring advanced radio technologies to life faster than ever before.

We're hiring a Senior Avionics Mechanical Engineer to own the mechanical design of our space radios — the housings, thermal paths, and structures that let high-performance RF hardware survive launch and operate reliably on orbit.

This is a hands-on design role first. You will personally own enclosure designs from concept through drawings, fabrication, and qualification, and you will be the person who signs off on whether a structure will hold and a part will stay within temperature. Mechanical design at Any Signal is currently distributed across a small hardware team; you will be the senior technical voice for the discipline, set how mechanical work gets done here, and shape the team as it grows around you.

• Own mechanical design of space radio enclosures and chassis end to end: concept, CAD, detailed drawings, fabrication, assembly, and qualification.
• Design the thermal path — conduction, interface materials, heat straps and radiators — and run hot- and cold-case analysis for vacuum operation, then correlate your models against test data.
• Perform structural analysis including static, modal, and random vibration FEA; own margins of safety, fastener and joint analysis, and mass and CG budgets.
• Plan and run environmental qualification campaigns — vibration, shock, thermal vacuum, thermal cycling — including test plans, fixture design, and time on the floor at the test house.
• Select materials and processes appropriate to the space environment: alloys and finishes, low-out gassing materials, venting, contamination control, and galvanic compatibility.
• Produce manufacturing-ready drawing packages with GD&T to ASME Y14.5, and work directly with machine shops and contract manufacturers on DFM, quoting, and first‑article inspection.
• Partner with RF and PCB engineers on SWaP trades, board mounting and standoffs, connector and waveguide placement, shielding, and grounding.
• Own mechanical interface control documents with customers, bus providers, and integrators.
• Lead mechanical content at design reviews and hold the line on documentation and configuration control.
• Establish the mechanical engineering practice: CAD and drawing standards, PDM structure, review cadence, and analysis conventions — then mentor engineers into them and help us hire well as the team grows.

• 6+ years of mechanical design experience, including hardware that has flown or been qualified for flight.
• Expert‑level CAD (Solid Works preferred; NX or Creo equivalent) and detailed drawings with GD&T to ASME Y14.5.
• Demonstrated ownership of thermal design for vacuum environments, including analysis and correlation to thermal vacuum test results.
• Structural analysis and FEA experience covering random vibration and shock, with the judgment to know when analysis is sufficient and when to test.
• Direct, hands‑on ownership of at least one environmental qualification campaign from test plan through report.
• Strong DFM instincts for precision machining and sheet metal, with a track record of working shops effectively.
• 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.

• 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…
