Senior Mechanical Engineer

AnySignal•Los Angeles, CA

7d•$170,000 - $205,000

About The Position

AnySignal 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 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 AnySignal 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.

Requirements

6+ years of mechanical design experience, including hardware that has flown or been qualified for flight.
Expert-level CAD (SolidWorks 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.

Nice To Haves

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.

Responsibilities

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-outgassing 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.
