Overview

We are recruiting a Sr. Firmware Engineer to contribute to our IoT teams.

Key Responsibilities

Owning firmware architecture decisions across one or more active product platforms
Bringing up new hardware revisions and integrating peripheral drivers with minimal ramp time
Monitoring deployed firmware in the field, triaging issues, and shipping fixes with urgency and discipline
Designing and implementing wireless connectivity flows - pairing, OTA, reconnect logic, fleet health
Reprocessing and validating firmware behavior across hardware variants and edge cases
Integrating new sensors, actuators, and communication modules into existing firmware architectures
Participating in code reviews and holding a high bar - style, correctness, and long-term maintainability
Keeping close track of project scope, timeline, and technical risk - and surfacing problems before they become crises
Communicating directly with clients to align deliverables with constraints when scope and reality diverge

Requirements

Writes production C/C++ at the register level — owns memory layout, interrupt handling, and real-time constraints without supervision
Has shipped embedded firmware through DVT into mass production on at least one product with real end users
Brings up new hardware independently: bootloader, BSP, device tree, peripheral drivers — no hardware team babysitting required
Deep RTOS fluency (FreeRTOS preferred) — has designed and debugged scheduling, priority inversion, watchdog logic, and power state machines under real constraints
Owns the full debug cycle: reads schematics, probes with lab instruments, isolates timing and concurrency bugs, writes the postmortem
Fluent in low-level bus protocols (I2C, SPI, UART, GPIO) at the register level - not just framework calls
Self-managing: sets accurate estimates, flags risk early, delivers without being chased, and owns scope from kickoff to close
Client-facing: has communicated technical tradeoffs directly to non-engineers, in writing, in real time, and been the person the client calls

Benefits

The pay scale is on a contract basis, ranging from $150-200k/year based on experience.
