IoT Embedded Firmware Team Leader

We're looking for an IoT Embedded Firmware Team Leader to build, lead, and scale a hands-on team developing MCU-based firmware for our connected edge devices and sensors. You'll own firmware architecture and delivery end-to-end, including low-power sensing, connectivity, security, diagnostics, and OTA, while partnering closely with hardware, manufacturing, product, and backend teams to ship reliable devices at scale.

A Day In Your Life
Team Leadership & Delivery
Lead, mentor, and develop a team of 4–6 embedded firmware engineers; drive hiring, onboarding, coaching, and career development.Own the firmware roadmap and delivery: planning, scoping, estimation, risk management, execution, and incremental releases aligned with product milestones.Establish engineering standards, design reviews, code reviews, documentation, testing, and quality gates, to ensure safe and repeatable releases.Firmware Architecture & Development
Architect and implement MCU firmware (ARM Cortex-M or similar) in C/C++ on RTOS platforms (e.g., FreeRTOS, Zephyr), including drivers, HAL, bootloaders, and application services.Integrate sensors and peripherals over SPI/I²C/UART/ADC/DMA; design resilient state machines, timing, and power-optimized flows for battery-operated devices.Develop secure OTA pipelines for MCU-based devices (MCUboot/DFU/custom) with signing, versioning, rollback, and safe fleet rollouts.Connectivity & Device Functionality
Implement reliable connectivity flows: BLE (central/peripheral, GATT), gateway interactions, and where relevant, cellular IoT (LTE-M/NB-IoT) modem control.Design device-provisioning flows, identity management, and robust communication patterns.Quality, Security & Tooling
Raise firmware quality through unit and integration tests, HIL frameworks, static analysis (clang-tidy, cppcheck), and CI-based cross-compilation.Embed security by design: secure boot, key storage/rotation, cryptographic primitives, SBOM/CVE tracking, and layered security for constrained systems.Build factory tooling and production test applications: programming/provisioning flows, calibration, and end-of-line testing in partnership with manufacturing.Enable diagnostics and reliability at scale: structured logging, device health metrics, watchdog/recovery flows, and remote triage playbooks.Cross-Functional Collaboration
Work closely with hardware, Embedded Linux, QA, backend, and product teams to define requirements and deliver cohesive device-to-cloud experiences.What You Bring
6–10 years of embedded firmware experience shipping MCU-based products to production, including 2+ years leading engineers as a team lead or people manager.Expert-level proficiency in C/C++ for constrained MCUs with strong RTOS fundamentals (tasking, timing, ISRs, memory management) and deep understanding of bootloaders/startup flows.Hands-on board bring-up and debugging experience: JTAG/SWD, oscilloscopes, logic analyzers, power profiling, and HW/SW co-debugging with electrical engineers.Strong experience integrating sensors and peripherals over SPI/I²C/UART/ADC/DMA, with robust state-machine and error-handling design.Wireless connectivity experience: BLE stacks (GAP/GATT) and gateway communication; familiarity with LTE-M/NB-IoT is a plus.Experience delivering secure OTA update systems for MCUs, including signing, rollback, and phased rollouts.Low-power design expertise for battery-operated devices: sleep states, clocking, duty-cycling, and storage wear considerations.A rigorous testing and quality mindset: unit/integration tests, HIL, static analysis, CI/CD, and fleet-scale release discipline.Strong communication and collaboration skills; ability to align cross-functional teams and drive outcomes.BSc in EE, CE, CS, or equivalent experience.Nice to Have
Experience with Zephyr or FreeRTOS internals; Rust or Go for tooling/services; Python for test automation and factory systems.Knowledge of cellular IoT stacks (PPP, CoAP, LwM2M), GNSS, and modem AT command workflows.Advanced security experience: secure elements/TPMs, secure storage, PSA Certified, Arm TrustZone.DSP/ML at the edge (filters, FFT, fixed-point) for sensor/vibration analytics.Manufacturing exposure: large-scale programming/provisioning, calibration, quality workflows, and traceability.
