C++ Software Development for Embedded Systems

What does professional embedded C++ development include?

We build high-performance, maintainable C++ software from architecture to delivery – shaped around the tight constraints of embedded systems.

• Modern C++ (11/14/17/20/23) & clean design: idiomatic, resource-safe code (RAII, move semantics, templates) instead of risky C-style patterns
• Architecture & API design: cleanly separated modules and stable interfaces that stay extensible years down the line
• Performance optimization: deliberate work on runtime and memory footprint, on concurrency and on data races and deadlocks – backed by static and runtime analysis
• Unit & integration testing: automated tests (e.g. with GoogleTest) in a CI pipeline, so changes don’t turn into regressions

Whether greenfield development or evolving an existing codebase, we match scope and depth to your product and your target hardware.

When should you bring in an external C++ consultancy?

An external C++ consultancy pays off whenever specialist expertise gets you to the goal faster than building it up in-house.

Typical triggers are:

• New product development (greenfield): you’re starting a device or platform from scratch and need a sound architecture from day one.
• Modernizing existing codebases: migrating from C to C++, refactoring grown legacy software, or migrating from Qt 5 to Qt 6.
• Performance and stability bottlenecks: existing software is too slow, too memory-hungry or crashes under load – we find the root cause and fix it.
• Team augmentation for project peaks: when C++ capacity or deep embedded know-how is missing short-term, our team steps in with minimal ramp-up.

Collaboration often begins with a code audit or an architecture review before we go deeper into implementation.

How do we connect C++ with Embedded Linux and hardware?

We don’t write C++ in a vacuum – we write it for the hardware it will actually run on.

This is exactly where real embedded know-how differs from pure application development: we handle board bring-up and the device tree, maintain the BSP (board support package) and adapt kernel and drivers where needed. We set up cross-compilation with toolchain and sysroot so your software builds reproducibly for the target.

For user interfaces we bring C++ together with Qt and QML – on embedded devices directly on EGLFS, without desktop overhead. The Embedded Linux platform beneath it and the Yocto BSP come from the same team. For field updates we integrate robust OTA strategies with A/B partitioning – for example based on RAUC, SWUpdate or Mender, depending on your requirements.

How do we ensure code quality and maintainability?

For us, quality doesn’t come from testing at the end – it comes from architecture and discipline from the start.

Concretely, that means a clean, documented architecture, regular code reviews, static and runtime analysis (e.g. with sanitizers and static analyzers), and automated unit and integration tests in CI. That keeps concurrency bugs, memory leaks and regressions manageable. Just as important is knowledge transfer: we hand over not just code but the understanding behind it – with documentation and, if you like, pairing – so your team can carry the software forward on its own.

Why choose bitshift dynamics as your C++ partner?

Because here a specialist embedded focus meets senior experience – not a generalist doing C++ on the side.

We bring many years of experience in hardware-related C++ software, are based in Lörrach in the tri-border region, and work remotely or on-site across the DACH region, in German and English. The full stack – C++, Qt/QML, Embedded Linux and Yocto – comes from one team rather than being stitched together across the seams between vendors. You’ll find concrete reference projects in our portfolio.
