Hardware Technician - Electrical and Mechanical

Hardware Technician - Electrical and Mechanical

Citizens and permanent residents only – we do not sponsor and cannot hire non‑citizens or PRs. We work six days a week in the office in downtown San Francisco; remote is not available.

Aurelius Systems is a directed‑energy company developing edge‑deployed laser systems for counter‑unmanned aerial systems (cUAS). Our mission is to provide scalable, advanced, and cost‑effective defense solutions for the U.S. and our allies. We are building the team to launch our flagship product, The Archimedes laser sentinel, protecting servicemen, servicewomen, and domestic security forces.

We are seeking a Hardware Technician to rapidly build, modify, test, and iterate on physical hardware designs created by our R&D team. This role is deeply hands‑on and execution‑focused: turning drawings, schematics, and concepts into real, working hardware—fast.

You will be a force multiplier for engineers by keeping prototypes moving and experiments unblocked.

• Assemble, wire, and integrate electromechanical systems and prototypes, building against design cycles for mostly bespoke designs.
• Build and rework:
  • Mechanical assemblies
  • Wiring harnesses and cable assemblies
  • Test rigs and fixtures
• Support rapid iteration cycles by:
  • Modifying designs when problems arise
  • Proposing manufacturing and assembly methods
  • Implementing engineering change requests
  • Troubleshooting physical issues
• Operate and maintain lab equipment, tools, and prototyping infrastructure.
• Assist engineers during bring‑up, debugging, and testing.
• Document builds, revisions, and lessons learned.
• Help maintain a clean, organized, and safe lab environment.

• 2+ years of hands‑on hardware technician, lab technician, or similar experience.
• Strong practical skills with hand tools, power tools, torque tools, crimping, soldering, cable routing.
• Mechanical assembly and alignment.
• Ability to read and work from mechanical drawings, schematics and wiring diagrams, and assembly instructions.
• High mechanical intuition and attention to detail.
• Comfort working in a fast‑moving R&D environment where designs change frequently.

• Experience with precision assemblies, optics, robotics, or aerospace hardware.
• CNC, 3D printing, and machining experience.
• Familiarity with embedded systems or electronics debugging.
• Experience with significant “builder” hobbies—electronics tinkering, smart home, automotive garage work, etc.

Speed wins. This role directly determines how quickly ideas turn into working hardware.
