What they need
needCode builds embedded firmware and wireless connectivity for automotive and IoT clients - UWB, BLE and short-range radio, from silicon bring-up to production. We're hiring firmware engineers to work across client projects: battery-powered wireless devices on one end, networked and mains-powered devices on the other.
What you'll do
- Write production C/C++ firmware for microcontrollers, on RTOS and bare metal.
- Bring up new boards from schematics and reference designs; debug at the hardware level.
- Integrate radio transceivers and NFC — driver work from the datasheet, session management, timestamping and time synchronisation.
- Bring up Wi-Fi and 2.4 GHz mesh connectivity, and handle coexistence between stacks sharing the band.
- Implement low-power operation: duty cycling, sleep/wake paths, measured power budgets.
- Build secure device identity, provisioning, and OTA updates with rollback and recovery.
- Deliver telemetry, remote diagnostics, calibration and automated test on real hardware.
You need
- 5+ years commercial embedded firmware development in C/C++.
- Radio work on constrained devices - you've integrated a transceiver from the datasheet up, not just called a vendor SDK.
- Wireless connectivity expertise: UWB(IEEE 802.15.4z/4ab, FiRa) or/and BLE
- Board bring-up and hardware debugging (scope, logic analyser).
- Either low-power battery devices or networked embedded systems in depth, with working knowledge of the other.
- Peripheral drivers, field firmware updates, comfort with vendor specs and errata.
- Version control, code review, automated testing.
- English at working level - most of our clients are international.
Nice to have
- NFC, 802.15.4 mesh.
- Zephyr or FreeRTOS.
- Secure element / hardware root of trust.
- Power over Ethernet.
- Automotive-grade development practices
