Embedded software engineers and firmware developers

Bring in hands-on embedded engineers to develop device software and resolve hardware-level faults. Firmware developers and real-time systems specialists support new products and devices already in service.

What do you need help with?

New hardware needs working firmware

A prototype needs board bring-up and peripheral drivers before application development can progress. Firmware developers implement startup code and validate device behaviour against schematics and hardware measurements.

Timing faults affect device behaviour

Missed deadlines or intermittent lockups are disrupting operation. Real-time systems specialists trace scheduling and interrupt behaviour, then address contention or priority inversion against defined timing requirements.

An embedded Linux platform needs adaptation

A new board or peripheral requires changes below the application layer. Embedded Linux engineers adapt the board support package and device drivers, then validate communication with connected equipment.

Released devices need continued engineering

Field failures and component changes are creating a firmware backlog. Embedded engineers reproduce reported faults and maintain regression tests while preparing compatible software updates for existing devices.

Firmware development and board bring-up

Digiventi provides embedded software engineers who join your team to develop C and C++ firmware for microcontrollers such as STM32 and Nordic nRF52. Bring in a firmware developer when new hardware needs executable code or existing firmware blocks product development.

Board bring-up: Implement startup code and bootloaders, then check clock configuration and memory layout against the hardware design.
Peripheral drivers: Develop interfaces for sensors and actuators using SPI or I2C. Diagnose signal-level faults with oscilloscopes and logic analysers.

Real-time systems and RTOS development

Real-time systems specialists develop bare-metal applications and RTOS-based firmware with FreeRTOS or Zephyr. They translate timing requirements into task priorities and interrupt handling, then measure behaviour on the target hardware.

For missed deadlines or intermittent stalls, engineers investigate priority inversion and shared-memory access. Work can include DMA integration and bounded memory allocation, with trace-based checks of execution time and scheduling latency. This expertise is relevant when control loops or time-sensitive data acquisition cannot tolerate unpredictable execution.

Embedded Linux and device connectivity

Embedded Linux engineers adapt Linux-based devices to custom hardware and connect application software to peripheral interfaces. Scope can cover board support packages and application-facing services, with build configuration maintained in Yocto or Buildroot.

Platform adaptation: Modify U-Boot and device trees, configure the kernel, and implement device drivers for the target board.
Device communication: Integrate CAN or Modbus interfaces and diagnose protocol faults between devices. For networked products, implement MQTT communication and TLS certificate handling.

Firmware testing and ongoing support

Embedded test engineers and firmware developers support released products through fault investigation and software maintenance. They reproduce failures on target hardware and review crash dumps, then check corrective changes against existing device behaviour.

Testing work includes unit tests and hardware-in-the-loop regression suites integrated into CI pipelines. Specialists can also assess inherited code before a component replacement, maintain bootloader compatibility, and implement signed firmware updates with rollback handling. Continued support covers compiler upgrades and dependencies that affect reproducible builds.

Selected work

Enterprise digital platform delivery for a European Qualified Trust Service Provider

A leading European trust service provider required senior technical and delivery capacity to manage the expansion of its national digital identity platform under strict regulatory deadlines. We deployed specialized consultants to support requirements scoping, AWS cloud architecture, and end-to-end integration workflows. The project was delivered on schedule, successfully rolling out compliant onboarding and biometric verification at national scale.
