Embedded firmware engineering · San Jose, CA

Reliable firmware, from silicon to ship.

FirmwareLab partners with hardware teams to deliver production-grade embedded firmware — from first board bring-up through secure, field-updatable products.

What we do

Firmware engineering, end-to-end

Three focused practices, one accountable team. We embed alongside your hardware and product engineers — not as a black-box vendor.

Embedded firmware development

Production firmware for industrial-grade MCUs through application-class SoCs — from ARM Cortex-M4F / M7 / M33 up to Zynq-class SoC-FPGAs. Built to your spec, your toolchain, your memory budget.

  • RTOS (FreeRTOS, Zephyr, ThreadX) and embedded Linux (Yocto, PetaLinux)
  • Peripheral drivers, sensor stacks, and signal-chain integration
  • Industrial connectivity: CAN-FD, Modbus, EtherCAT, BLE, Wi-Fi, MQTT
  • Power-aware design, deterministic timing, low-power profiling
Discuss your firmware

Hardware & firmware bring-up

The crucial gap between EE and software. We get your first prototypes booting, characterized, and ready for the next revision.

  • First-light bring-up, clock trees, boot ROM, memory init
  • Bootloader development (signed, dual-bank, fail-safe)
  • Board support packages, HAL, and driver layers
  • Hardware validation, signal capture, schematic feedback
Get hardware booting

Firmware security & OTA

Ship updateable, attest-able products. We design the trust chain end-to-end — from key provisioning at the factory to signed updates in the field.

  • Secure boot, ARM TrustZone, RoT integration
  • Signed and encrypted OTA delivery pipelines
  • Key provisioning, anti-rollback, attestation
  • Vulnerability response and long-term update strategy
Secure your fleet
How we work

A predictable path from concept to production

Every engagement runs the same disciplined cycle. You always know where the firmware is, what's next, and what risks remain.

1

Discovery

We review your hardware, ICs, schematics, and product targets. Outcome: a written scope, risk list, and a feasible delivery plan.

2

Bring-up & architecture

First boot, clock and power validated, drivers proven on real hardware. The firmware architecture is decided up-front, not improvised.

3

Iterate & verify

Short cycles with working firmware, automated tests on hardware-in-the-loop, weekly demos, and full source under your version control.

4

Productionize

Manufacturing flash tooling, secure provisioning, OTA infrastructure, and a documented hand-off your team can own and extend.

Why FirmwareLab

Senior firmware engineers — not a body shop.

Connected products live or die at the firmware layer. We've shipped industrial sensors, medical devices, consumer hardware, and robotics — and we treat your codebase like one we'll have to maintain ourselves. We also lean into AI — at the edge in your products, and across our own AI assisted engineering workflow.

  • Senior engineers, on your bench Every project is staffed by engineers with 10+ years shipping production firmware. No offshoring, no juniors learning on your dime.
  • You own the code All source, build scripts, and toolchain config live in your repo from day one. Clean hand-offs, no lock-in, no licensing surprises.
  • Tested on real hardware Hardware-in-the-loop CI from week one. We catch the bugs that only show up at 3.3V, in interrupt context, on the actual board.
