Required Skills & Abilities
8+ years building firmware for resource-constrained systems, You have delivered reliable firmware where memory, processing power, energy and timing are all scarce, and you know how to measure, optimize and make deliberate trade-offs between them.
You have led firmware development for several new products end to end. You have taken firmware from initial concept through architecture, technical implementation, validation, and product launch, providing hands-on technical leadership throughout.
Substantial bare-metal and RTOS experience - Zephyr, FreeRTOS, or equivalent. You have made scheduling, memory and timing decisions. Mutexes and semaphores are everyday tools for you.
You have brought up new boards. First power-on of unproven hardware, at the bench with the electrical engineer who drew it up, working out whether the bug is in your code, a library, the schematic, or the part itself.
Fluency in the low-level interfaces - SPI, I2C, UART, CAN, ADC and the ability to debug the seam between hardware and software.
Real bench instincts. The usage of an oscilloscope, network analyzer, or RF spectrum analyzer, is how you form a hypothesis, not what you reach for after the print statements run out.
Senior-level scope. You have led work spanning hardware, firmware, cloud and quality from concept to shipped product. You have consistently driven consensus across teams.
Cross-layer judgment. You can trace how a decision at the driver level surfaces in a customer's experience three layers up, and you make that trade-off on purpose.
Fluency in C. You know what the compiler is doing, and you can read a linker map, a stack trace, or a corrupted heap without guessing.
You write things down. Design docs, review comments and post-mortems that other engineers can actually act on.
You ship fast without shipping badly. Comfortable iterating on customer feedback at speed, backed by automated testing and code you would be content to inherit.
You use AI smartly. It’s part of your every day work flow and multiplies your output without watering things down.
BLE at depth - You understand what’s going on down the PHY and can build orchestration for the system to use in a performant and power efficient way.
Cellular IoT - LTE-M or NB-IoT modem integration, power state management, and the certification gauntlet (FCC, PTCRB, carrier approval).
Securing embedded systems end to end - secure boot, firmware signing, cryptography, and key management that survives contact with manufacturing.
OTA and device firmware update at fleet scale - A/B partitions, rollback, and the discipline of never bricking a device you cannot physically reach.
You’ve been on the factory floor - You have an understanding of the processes behind the mass production and quality assurance of electronics. You have a track record of fixing production show stoppers.
