What we build

Our Embedded Software Development Services.

From board bring-up to long-term reliability, built to scale with your product.

01

Board support packages & OS porting

BSP development and OS porting that bring up your hardware cleanly and reliably.

Why Brilworks

Why engineering teams choose us.

Plenty of firms can write embedded C. Fewer build embedded software development services around the thing that actually matters: code that holds up after you've moved on.

01

Firmware designed for production, not prototypes

We build for the device that ships and runs for years, not the demo that works once on a bench.

02

Hardware and software expertise under one roof

We solve problems across firmware, electronics, and connectivity instead of pointing at the other side of the line.

03

Modular code your team can maintain

Documented, modular architecture your engineers can read and extend six months later. You keep the source.

04

Flexible engagement, no long hiring cycle

Take a dedicated team, or embed our engineers in yours. Start with one and grow into the other.

Selected work

Two builds, both running right now.

Every project below is running in production today. These aren't proof-of-concepts or demo firmware — they're systems people rely on every day.

★★★★★

Strong expertise with STM32, FreeRTOS, and MQTT, with clear communication throughout. They delivered high-quality work and adapted as requirements evolved.

Director of Engineering
★★★★★

What stood out was their focus on building for production, not just making features work. Maintainability, fault recovery, and reliability from the very beginning.

How we work

Our engagement models.

Flexible models to match your stage, whether you need a full firmware team, extra embedded hands, or a fixed build delivered end to end.

Dedicated Development Team

A full embedded team of firmware engineers, hardware integration specialists, and QA, working only on your product. Best for companies building a core connected platform.

Priced: dedicated team, monthly.

Team Extension

Add our embedded engineers to your existing team. They join your repo, standups, and processes and read your platform fast. Best for scaling without the hiring cycle.

Priced: per engineer, monthly.

Project-Based Model

Fixed scope, fixed deliverable. We own the firmware from board bring-up to cloud, tested and documented. Best for a defined product or a well-scoped build.

Priced: fixed-scope, quoted per project.
Finding engineers who can quickly understand an existing embedded platform isn't easy. They onboarded quickly, worked independently, and stayed aligned with our processes. We would gladly work with them again.Embedded Systems Lead
How it runs

How we deliver production-ready firmware.

No mystery, no disappearing act — whether we build it or join you.

01

Scope

Map the hardware, constraints, and what 'done' means before any number.

02

Architect

Tasks, scheduling, fault model agreed up front. The expensive-to-change decisions.

03

Build

Firmware on real hardware. Drivers up, debugged across the hardware line.

04

Validate

We test the bad day: network loss, faults, continuous operation.

05

Hand off

Documented, modular code. You keep the source. No lock-in.

Their engineers integrated from day one. They took the time to understand our product architecture and quickly became a trusted extension of our engineering department.Engineering Manager

Before you call

The questions we get most.

You do. Source code, documentation, and the repository transfer to you at handoff. No lock-in.
Yes, most of our work is exactly that. We build to your schematics alongside your EE team.
Too device-dependent for a number here. Fixed-scope work is quoted per project; staffing is monthly per engineer.

Tell us what you're building.

Whether you're starting from a new board or improving an existing platform, we'll help you define the right approach before any code is written.
