Outsourcing embedded software development is a strategic move that allows companies to focus on core business aspects while leveraging external expertise in specialized technological solutions. As said Andrew Tanenbaum, author of Operating Systems: Design and Implementation,
"Embedded systems are unique because they demand both the precision of hardware engineering and the creativity of software development"
For CTOs and technical leaders, understanding the mechanisms of outsourcing is key to making informed decisions that can support the long-term growth of the company.
In this article, we will examine how embedded software development outsourcing works, its advantages, and what to consider when choosing an embedded software outsourcing company.
Most outsourcing failures come from a partner who codes but cannot debug on real hardware. Our embedded engineers take firmware, drivers and integration through to a working device.
Talk to an embedded team that owns delivery
Embedded software is a crucial component of modern devices, responsible for controlling their operation. From control systems in cars to medical devices and complex industrial machines, it determines how these devices function.
It is estimated that in 2022 there were approximately 31 billion devices with embedded systems worldwide, and this number continues to grow with the expansion of IoT and the development of new technologies.
This software operates within a precisely defined hardware environment, where reliability, efficiency, and precision in executing specific tasks are paramount. There's no room for errors or delays - everything must work as intended to meet the requirements of the given system.

Why the game is worth the candle? Outsourcing embedded software and firmware development is a strategy that allows companies to tap into the expertise and experience of external specialists for creating, maintaining, and enhancing software tailored to specific devices. For IT companies, this means collaborating with experts who not only excel in the latest technologies but also have a deep understanding of hardware and software requirements. This approach enables businesses to quickly and efficiently implement advanced technological solutions, gaining a competitive edge in the market without the need to build such competencies in-house. That combined hardware and software understanding is the main thing to verify in a partner, and it is the basis of our engineering outsourcing services for device makers.
Rates and time zones move together. Whether the partner sits in your country, in a nearby market or on another continent changes both the hourly rate and the cost of every review cycle, and nearshoring vs offshoring vs onshoring breaks down that trade-off before you start comparing quotes.
Outsourcing embedded software projects and development offers numerous benefits to companies, especially in industries where technology and product innovation are critical. Here we've prepared an overview of the key advantages.
Software developers of embedded systems operate at the intersection of various technologies and architectures, often working in complex and demanding environments. Their development teams of specialists not only utilize advanced tools such as compilers, debuggers, simulators, emulators, and tools for code analysis and version control, but they are also proficient in key industry standards like MISRA, ISO 26262, and DO-178C. This expertise enables them to deliver software that not only meets stringent requirements but is also robust, error-resistant, and ready for the most critical applications.
It should also be remembered that outsourcing software development to an external company allows an organization to save a significant amount of time, and it is well known that time is money. An external company, already equipped with proven processes, tools, and an experienced team, can deliver a ready-made solution more quickly, thus shortening the project timeline. These companies often employ Agile methodologies, which enable flexible project management, rapid iterations, and regular delivery of working software versions. As a result, the project can be executed at a pace and scale that would be difficult to achieve internally, especially in organizations where software development is not the core activity.
Moreover, external teams often have access to the latest tools and technologies, such as advanced CI/CD (Continuous Integration/Continuous Deployment) systems, test automation platforms, or modern code analysis tools, which can significantly enhance the efficiency of the software development process.
At the same time, by delegating such tasks, the organization can focus on its core business areas and activities that bring the most added value, rather than investing time and resources in developing skills outside of its core competencies. As in other fields, the Pareto principle applies here as well, which states that 20% of actions generate 80% of the results. So, is it worth spreading yourself too thin?
Embedded systems have specific hardware requirements, including limitations on memory, computational power, and energy consumption, making software development for such systems extremely challenging and requiring specialized expertise. The software must run efficiently on hardware with limited resources, necessitating meticulous planning of every aspect of the code. This means implementing algorithms with low memory demands and minimal energy consumption, which is important in battery-powered systems or those operating in harsh environmental conditions.
Additionally, embedded systems often function in critical environments, such as healthcare, automotive, or aviation, where failures can lead to serious consequences. Therefore, the software must be exceptionally reliable and secure. There is no room for errors, as any mistake can cost millions of dollars. It's no surprise that advanced testing and verification methods are employed in embedded systems.
Furthermore, developers must ensure that the software is resilient to interference, hardware failures, and unforeseen operational situations. Redundant error control systems, automatic restart mechanisms, and other techniques are often used to enhance fault tolerance.
Eliminate the Hassle of Hard Integration

To develop embedded software, it must be designed to efficiently communicate with various hardware components and peripherals, which may be based on different communication standards, such as UART, I2C, or SPI. This requires developers to have a deep understanding of the technical specifications of each of these protocols, as well as the ability to optimize the code to ensure that communication is as efficient and reliable as possible.
For example, in an automotive system, the engine control unit (ECU) may communicate with other units via the CAN protocol, which demands low latency and high reliability. On the other hand, in an IoT system where devices communicate wirelessly, it is essential to ensure security and minimize power consumption, which presents additional challenges.
Moreover, embedded systems often need to support various hardware interfaces, such as GPIO, PWM, ADC, DAC, requiring additional knowledge of the capabilities and limitations of these interfaces. Developers also need to ensure that the software is scalable and flexible, so that new devices can be easily integrated, or existing connections updated, without making significant changes to the entire system.

Not sure where to start? We work with companies at every stage, from early ideas to enterprise-level builds. A 30-minute call can save you months of guesswork.
An embedded software outsourcing project typically runs through requirements analysis, architecture design, implementation, integration on target hardware, verification and handover or maintenance. The early phase fixes the target MCU or SoC, operating system, interfaces and test strategy. Implementation proceeds in increments demonstrated on development kits or prototype boards. Integration with final hardware is the highest-risk step, so good plans schedule it early. Handover should include source code, build environment, test reports and documentation, not just binaries.
Evaluate an embedded software vendor by examining how it builds and verifies firmware, not only its list of technologies. Ask for experience with your processor family and RTOS or embedded Linux, coding rules such as MISRA C, and relevant standards like IEC 62304 or ISO 26262 if applicable. Review a code sample, a test plan and a past integration issue they solved. A vendor with its own lab, debug probes and hardware-in-the-loop setups can reproduce field problems instead of guessing.
IP and licensing clauses should assign ownership of all source code, build scripts, test code, schematics and documentation to the client, with delivery at each milestone. They should require a list of third-party and open-source components with their licenses, because GPL-licensed code linked into firmware can create disclosure obligations. The contract should state what happens to vendor-owned libraries or tools, and whether the client receives a perpetual license to them. Escrow is worth considering for long-lived products.
A CTO keeps control over an outsourced firmware project by owning the repository, the build pipeline and the acceptance criteria. The client should host or have full access to version control and CI, see every merge, and run its own review of architecture decisions. Regular demonstrations on real hardware, not slide reports, show actual progress. Defined milestones with testable exit criteria, plus an internal engineer who understands the codebase, prevent the project from becoming a black box.
Post-release support for outsourced firmware covers bug fixing, security patching, updates for component changes and occasional feature work. A service level agreement should define response and resolution times by severity and how field issues are reproduced. Security work is growing in weight: vulnerability monitoring of third-party libraries, secure update delivery, and in the EU the obligations introduced by the Cyber Resilience Act. Component obsolescence can force hardware and driver changes years after launch, so support terms should anticipate it.
