Firmware
We help companies take products from concept to production. With a firmware team of over 25 engineers, we bring deep expertise alongside electrical, mechanical, and systems engineering under one roof—reducing coordination friction and enabling faster, more predictable development cycles.
Firmware Design
Our firmware engineering team brings decades of hands-on experience delivering reliable, production‑ready code for embedded systems. We specialize in low‑level firmware development for microcontrollers ranging from resource‑constrained 8‑bit devices to high‑performance 32‑bit ARM Cortex processors. Our engineers work across all major embedded ecosystems, including Nordic, Silicon Labs, STMicroelectronics, Renesas, Microchip, Infineon, NXP, Qualcomm, and Texas Instruments.
We design and implement real‑time solutions using FreeRTOS, Zephyr, and custom RTOS environments for applications that demand deterministic timing and precise task scheduling. Our capabilities extend through the full embedded Linux stack, including board support packages (BSPs), kernel modules, device drivers, and application development. From boot-time optimization and hardware bring‑up to custom touchscreen GUI development, we provide end‑to‑end firmware solutions that are stable, secure, and ready for production.
Firmware Expertise
Firmware is what brings hardware to life and what determines whether a product performs reliably outside the lab. We’ve optimized low-power firmware for battery-operated devices designed to run for years, debugged code in high-stakes applications where failure isn’t an option, and built embedded Linux systems with fast, consistent boot times.
The difference between firmware that works on the bench and firmware that ships at scale comes down to experience. We account for edge cases, fault handling, power management, and system-level interactions from the start because those are the details that define performance in the field. Our structured development process ensures firmware is aligned to system requirements, budget, and schedule, with clear specifications and measurable performance criteria established upfront.
We design firmware with production in mind focused on stability, maintainability, and long-term performance. From architecture through validation, our team builds code that’s ready for real-world conditions, not just controlled environments.

“I have used Indesign for the schematic review and layout creation. Their team is easy to work with, super knowledgeable and very responsive. I was extremely satisfied with the quality of their work. They delivered the work in the timeline promised. I would definitely work with them again.”
"As the owner of a small business for approximately 38 years, it has always been my experience that most large companies are very difficult to work with. Customer care seems to have "vanished". What I can tell you about Indesign is that these people actually CARE about what they do and how they handle their clientele. From start to finish Indesign has provided me with an experience second to none. These engineers are a total pleasure to work with. I just can't say enough about Indesign other than if you are looking for quality with a caring attitude, you need to call Indesign!"
“In short, these guys are the True A Team. When I brought my prototype in, they already had a plan in an hour, very impressive. They finished over a week ahead of schedule, and from budgeted quote to final payment, Indesign far exceeded expectations. I very much look forward to a continued relationship with this group.”
