We’re hiring a Senior Embedded Software Engineer to design, build, and ship production‑grade firmware for connected devices using Zephyr RTOS on ARM Cortex‑M . You’ll own features end‑to‑end—from requirements and architecture through implementation, test automation, and performance optimization—with a strong emphasis on reliability, security, and low‑power operation.

What You’ll Do

• Deliver embedded software across the full lifecycle: requirements → design → implementation → verification .
• Implement features across multiple subsystems (drivers, connectivity, power, security); debug complex issues across firmware, hardware, and toolchains.
• Work with devicetree/Kconfig , Zephyr drivers , and subsystem APIs (e.g., Bluetooth , UltraWideBand , NFC , logging , shell , PM ).
• Build and maintain automated tests ( ztest , Twister ) and CI/CD pipelines for firmware validation on real hardware.
• Perform hardware bring‑up (boot, clocks, peripherals, memory maps) using J‑Link/GDB/RTT/SWO.
• Collaborate closely with hardware, QA, and product to land features on schedule with high quality.
• Contribute to secure boot/FOTA workflows and production‑ready release practices.

Must‑Have Qualifications

• Bachelor’s degree in Automatics , Computer Science , Telecommunications , Electronics , or related field.
• 5+ years building firmware for ARM Cortex‑M devices, including at least 3+ years hands‑on with Zephyr RTOS .
• Strong C (and solid C++ familiarity), embedded design, and device‑driver development (I2C/SPI/UART, GPIO/EXTI, ADC/DMA, timers).
• Zephyr essentials: devicetree , Kconfig , CMake/west , Zephyr SDK/toolchains , boards/overlays, and subsystem integration.
• Connectivity experience with BLE (GAP/GATT) and at least one of UWB or NFC ; proficiency with protocol sniffers and analyzers.
• Proficient in debugging and bring‑up using J‑Link, logic analyzers, and oscilloscopes.
• Experience with CI/CD and automated test (ztest/Twister, HIL where applicable).
• Excellent written and spoken English .

Nice to Have

• Secure boot & updates ( MCUboot , DFU/FOTA), secure storage/crypto, key handling.
• Low‑power design (sleep states, timers, PM policies) and profiling methodologies.
• Knowledge of MISRA‑C , static analysis, and code review practices.
• Experience with Nordic nRF or similar SoCs (Bluetooth Controller/Host stack integration).
• Python for tooling/test harnesses; basic scripting for build/test automation.
• Familiarity with Agile workflows and backlog ownership.

Tools & Ecosystem

• Build: west, CMake, Zephyr SDK, Ninja, cache strategies.
• Test: ztest, Twister, HIL; unit/integration testing.
• Debug/Trace: J‑Link, GDB, RTT/SWO, logic analyzer, oscilloscope.
• CI/CD: GitHub Actions / GitLab CI / Jenkins; artifact versioning and release tagging.
• Collaboration: Code reviews, design docs, and clear communication across teams.
