Software Engineer, Embedded Hardware
Location: Cambridge, England, United Kingdom
Sweep360 is building a defense layer against increasingly intelligent machines. As an Embedded Hardware Engineer, you'll design and deploy the hardware systems protecting high‑stakes teams – from decision‑makers and elite market‑movers to frontline journalists, chart‑topping artists, record‑breaking athletes, and history‑bending scientists.
Why You Should Join
* Mission & Impact – Operate with the intensity of Bletchley Park: high stakes, rapid tempo, and zero room for failure. Your firmware will defend people in real‑world environments you may never discuss, but never forget.
* Innovation Ground‑Zero – Push the frontier of embedded systems, RF sensing, spatial intelligence, IoT hardware, and on‑device AI. Invent net‑new capabilities, not just iterate.
* Founding Ownership – Join the first ten engineers. Shape culture, engineering standards, architecture, and the hardware foundations that keep humans in control of autonomous machines.
What You’ll Do
* Build and optimize mission‑critical embedded firmware (C/C++, RTOS, embedded Linux).
* Integrate advanced sensors and wireless modules (BLE, Wi‑Fi, RF front‑ends, SDR) securely into embedded platforms.
* Architect hardened embedded security systems (secure boot, key storage, encrypted comms, tamper resistance).
* Conduct rigorous lab and field testing, penetration testing, and hostile‑environment simulations.
* Collaborate with tightly‑knitted software, hardware, AI, RF, and product teams to build tightly integrated end‑to‑end systems.
* Lead hardware bring‑up for new portable embedded platforms – from schematic review to bench testing, debugging, and validation.
* Support regulatory and certification workflows (FCC/CE testing, OTA signing, verification).
Must‑Have
* 5+ years building production‑grade embedded systems (firmware + hardware).
* Expert proficiency in C/C++, RTOS, embedded Linux, and low‑level systems.
* Proven experience integrating sensors, RF modules, BLE/Wi‑Fi, or SDR‑based systems.
* Deep understanding of embedded cybersecurity (secure firmware, cryptography, secure boot, protected comms).
* Experience navigating FCC certification, test houses, and OTA verification pipelines.
* Startup urgency: independent, accountable, relentless execution.
* U.S. Person status required (may involve export‑controlled data).
Nice‑to‑Have
* Experience with IoT, spatial computing, or sensor fusion.
* Cloud connectivity integration (AWS IoT, GCP IoT Core, MQTT).
* Familiarity deploying lightweight ML/AI models on embedded hardware (TinyML / Edge AI).
* Experience with low‑noise analog front‑ends, RF shielding, or board bring‑up.
Compensation
Base salary up to $240,000 annually, depending on qualifications, experience, and impact. Total compensation includes equity, premium insurance, and individual benefits.
Why Sweep?
Sweep selects for mission, impact, and ownership. Face‑to‑face collaboration is how we operate, thrive, and deliver. You'll join us on‑site at our NYC HQ or Hybrid in DC, London, Cambridge, UK.
Selection Process
Initial 20‑min intro → technical deep‑dive → team exercise → references → offer.
This is civilizational infrastructure. If you want to build toys this might not be for you. But if you want to help stop the next existential threat, step forward.
Make history. Build humanity's defense against machines.
