Custom Board Bring-Up.
We initialize raw silicon and configure low-level Board Support Packages (BSPs), transitioning your custom hardware from untested prototypes into fully validated computing platforms.
EMBEDDED FIRMWARE ENGINEERING
Firmware that gets your device past the demo stage.
A blinking prototype is not a stable product. NAK engineers production-ready embedded firmware built to handle unforgiving physical environments. We specialize in bare-metal, RTOS, and embedded Linux development. We own the low-level execution layer, spanning board bring-up with custom HAL/PAL drivers, automated manufacturing test feedback, fleet-management diagnostics, and fail-safe field updates.

WHY ENGINEERING TEAMS HIRE US
Firmware that makes hardware reliable enough to ship.
Firmware turns a working board into a product people can trust. NAK Engineering builds embedded firmware for connected hardware that has to manage power budgets, maintain wireless connections, and deploy secure over-the-air (OTA) updates without creating support nightmares.
We help engineering teams move from bench behavior to production confidence. We build clean state machines, precise execution timing, and hardware-aware diagnostics so your code behaves predictably through validation, manufacturing, launch, and the messy reality after launch.
EMBEDDED SYSTEMS CAPABILITIES
Production-ready firmware for connected products.
Embedded Linux, RTOS & Bare-Metal Firmware.
Our engineers develop deterministic embedded C and C++ architectures built to handle strict memory limits, hardware interrupts, and predictable multi-threaded task scheduling.
Drivers & HAL Architecture.
We deploy clean Hardware Abstraction Layers (HAL) and low-level peripheral drivers, ensuring displays, actuators, and sensors behave predictably under harsh field conditions.
Low-Power Profiling & Tuning.
We isolate dynamic hardware power draw to tune system clock gating, flash memory footprints, and sleep states—significantly extending deployment lifecycles for remote fleets.
Secure Boot & OTA Updates.
We engineer cryptographically signed bootloaders and fail-safe over-the-air update paths with automated rollback paths to prevent remote device bricking.
Production Readiness & Testing.
We implement Hardware-in-the-Loop (HIL) test suites and factory flashing toolchains to catch deep component assembly defects before units hit packaging lines.
Firmware Lifecycle Management
Firmware architecture built to keep your device working after launch.
Board bring-up is only the start. Real product work begins when parts change, factory tests need to catch failures quickly, and deployed devices need safe firmware updates without a recall. NAK designs embedded firmware with clear hardware abstraction layers, production diagnostics, validation support, and secure OTA update paths, so your codebase stays maintainable as your connected product moves from prototype to manufacturing to the field.

TECHNICAL ECOSYSTEM ALIGNMENT
HARDWARE PLATFORMS AND PROTOCOLS WE COMMAND.
A representative footprint of the embedded stacks we build on. We actively architect for your specific processing limits, power budgets, and supply chain constraints.
Silicon & Microcontrollers.
Production-scale deployment across STM32 (Cortex-M), Nordic Semiconductor (nRF series), and ESP32 ecosystems — selected and optimized to ensure multi-source hardware availability and mitigate component lead-time risks.
Operating Systems & Runtimes.
Deterministic runtime execution utilizing Embedded Linux, Zephyr, FreeRTOS, and custom bare-metal architectures — designed to guarantee strict multi-threaded task scheduling, low-latency interrupt handling, and precise runtime timing.
Frameworks & Build Toolchains.
Continuous integration and automated compilation managed via Yocto, Buildroot, West, STM32CubeIDE, nRF Connect SDK, ESP-IDF, PlatformIO, and CMake — utilizing GCC/Clang compilation toolchains to eliminate regression bugs before factory flashing.
Connectivity & Edge Protocols.
Low-power wireless orchestration over BLE, Wi-Fi, and cellular (LTE-M/NB-IoT) — local machine bus communication via CAN bus, serial (UART/SPI/I2C), and USB, and secure cloud streaming via highly optimized MQTT and HTTP pipelines.
