We build laser weapons to shoot down drones.\nWe're a small team of engineers, former US military operators, and subject matter experts scaling America's directed energy dominance. The first cost effective, reliable and robust laser weapon system.\nOur namesake isn't an accident. Marcus Aurelius wrote about doing the work in front of you, every day, without excuses. Henry Ford didn't wait for permission to reinvent manufacturing. That's how we operate — small team, unreasonable output, no hiding behind the unachievable.\nIn addition to our San Francisco lab, we’ve opened a Detroit manufacturing hub and we field test weekly on our own 400-acre private range.\nThe Role & Your Impact:\nYou're a forward deployed embedded engineer who loves R&D testing.\nYou write the firmware that exercises the system. You wire the electronics. You run the test scripts you wrote. You own the data path from scope trace to debrief slide. The thermal and ruggedization side of test will come from a different hire — your job is the full system integration testing from embedded to the electrical layer.\nWe're transitioning from prototype to product on an electromechanical directed energy system. The test infrastructure you build now becomes the foundation for everything we ship. You're not inheriting a test bench. You're designing it. You're not running someone else's HIL setup. You're building it from scratch and making sure it actually reflects what happens downrange.\nYou'll own verification and validation across embedded firmware, power electronics, electromechanical assemblies, and full-system integration. You're the single responsible party for ensuring all testing from top to bottom is completed and recorded as we move through the iteration process.\nWhat You'll Own:\nTesting end-to-end: setup, operation, data collection, teardown, post-test analysis, and failure writeups\nWrite firmware and embedded test code that exercises the system end-to-end (C/C++, real time)\nWire test electronics, build harnesses, instrumentation setups, and test fixtures\nDevelop automated test procedures in Python\nDebug across firmware, power rails, and electrical — root cause from first principles\nWork directly with embedded, electrical, and mechanical engineers to reproduce bugs, validate fixes, and prevent regressions\nDevelop test plans, acceptance criteria, and readiness gates as we move from prototype to production\nPartner with the hardware team on DFM and production readiness\nBuild HIL and SIL test environments\nEnforce safety procedures in high-power, high-voltage testing environments\nWhat We're Looking For:\n3+ years embedded firmware development experience — C/C++, real-time systems, scripting test exercises directly against hardware\nStrong electrical wiring and bench skills — scopes, logic analyzers, power supplies, DMMs, harness fabrication\nPython or scripting for test automation. You build your own tools.\nStrong debugging instincts across firmware, power rails, and electrical\nComfort with DFM concepts — you understand how production constraints shape what's testable\nPerformance, reliability, and safety testing as a combined skill set. You know how to stress a system, log what breaks, and define pass/fail criteria that actually matter.\nClear written communication around failures and root cause. Your test reports tell a story, not just a data dump.\nRobotics or defense companies with real electromechanical products where you wrote test code and wired test setups.\nNot a fit if: Your test experience is purely environmental/mechanical (vibe table, thermal chamber operator). Your debugging stops at the firmware layer. You've only operated someone else's test infrastructure. You've never wired your own bench setup. Your test experience lives entirely in Jira.\nNice-to-Haves:\nHIL or SIL test environment build experience (we'll need to build these — having done it before is a plus, but not required day one)\nMIL-STD, DO-178, or other safety critical testing standards exposure (even if informal)\nEnvironmental, vibration, thermal, or shock testing exposure\nHigh-voltage or high-power test environment experience\nFamiliarity with ITAR-controlled systems or working in cleared environments\nActive security clearance or ability to obtain one\nEducation:\nBS in Electrical Engineering, Mechatronics, Aerospace, or equivalent. Equivalent hands-on experience also considered.\nWhat you've built matters more than where you went to school.\nHow You Operate:\nExtreme bias for action. You'd rather build a prototype tomorrow than model it for a month\nRigorous testing mindset. You characterize your own systems before the field does\nComfortable with ambiguity and fast, constantly iterating in a startup environment\nYour brain only releases dopamine when you're building\nYou debug from first principles, not Stack Overflow\nClear communicator across mechanical, electrical, optical, and software teams\nSelf-directed. You identify what needs to happen next and do it without being told\nWhy Join Aurelius Systems?\nBuild more in 1 month than most engineers build in 1 year. We field test weekly. Your work goes downrange, not into a filing cabinet.\nCareer velocity is real. At ~10 engineers, there are no layers between you and impact.\nWork on a problem that actually matters. Small cheap drones are changing warfare. Our laser systems are the asymmetric answer — infinite magazine, near zero cost per shot, scalable to every base, border, facility, and truck.\nJoin the densest defense startup ecosystem in the country. California is where the next generation of defense companies are being built.\nHow We Work:\nCore hours are Monday through Friday, 9 to 6. When we're sprinting toward a demo or field test, the team ramps up — nights, weekends, whatever it takes to ship. When the sprint lands, we ramp down. We don't manufacture intensity for show.\nBenefits:\nCompetitive salary + equity\nUnited Health Care medical, dental, and vision coverage\nFlexible 18 days PTO + 5 sick days\nTravel to field test events and range days\nCovered daily lunches and office snacks + drinks\nE-bike / scooter stipend ( Up to $500)\nDirect access to leadership and real ownership over your work\nExport Control Notice:\nThis role requires access to export-controlled information or items that require \"U.S. Person\" status.
