Firmware Engineer: Salary and Responsibilities in 2026

When you switch on an electronic device, before its main software even starts, a first program runs: it initialises the processor, checks memory, configures peripherals and launches the rest. That program is the firmware. The firmware engineer develops this embedded code as close as possible to the hardware, and keeps it alive for the product's entire lifetime, including updates and security patches.

This role is a specialism within embedded engineering. For an overview of the field, see the embedded systems engineer page. This page focuses on what makes firmware specific: board bring-up, the direct link to the electronic board, and the life of the code after it leaves the factory. It also details firmware engineer salary and career paths.

Key takeaways

• Firmware is the software stored in an equipment's non-volatile memory, which makes it boot and run as close as possible to the hardware.
• The firmware engineer develops boot, drivers and low-level layers, and organises the product's updates once deployed.
• The Cyber Resilience Act reinforces their role: since 11 September 2026, manufacturers must report actively exploited vulnerabilities in their digital products.
• Salary: across our placements in the Engineering and Hardware family, which includes embedded roles, the median is €62,000 gross per year (5 placements). In the metalworking industry, the 2026 minimum collective pay for a manager classified G13 is €40,350 on a 35-hour basis.
• Career paths: lead firmware, embedded software architect, embedded team manager.

Firmware engineer, embedded engineer, low-level engineer: what are the differences?

The three titles overlap considerably, and companies do not always use them the same way. Here is how they are most often distinguished.

What characterises firmware is its link to a given electronic board and to the product's life cycle: firmware is written for a specific piece of hardware, it is often shipped alongside it, and it must be updatable for years.

What does a firmware engineer do?

1. Boot the board

• Take part in board bring-up with electronics engineers.
• Develop the bootloader, boot code and processor and memory initialisation.
• Write peripheral drivers: buses (SPI, I2C, UART, CAN), sensors, converters, memories.

2. Develop the product's low-level layers

• Develop the board support package (BSP) and integrate a real-time operating system or embedded Linux.
• Optimise code for memory, power and real-time constraints.
• Ensure robustness against power outages, memory errors and environmental conditions.

3. Secure and update

• Implement secure boot (cryptographic verification of the firmware at startup).
• Design the update mechanism, including over the air, with rollback on failure.
• Fix vulnerabilities and ship patches on products already deployed.

4. Test and industrialise

• Write tests on target and automate hardware test benches.
• Prepare production programming and diagnostic tools.
• Document the firmware and its versions.

Why has firmware become strategic?

Because a connected product does not stop the day it ships. Firmware is the layer that allows fixing a defect, adding a feature or closing a security hole on equipment already in service, sometimes across thousands of units.

The European regulatory framework reinforces this responsibility. The Cyber Resilience Act (Regulation (EU) 2024/2847) imposes cybersecurity requirements on manufacturers of products with digital elements. According to the European Commission, its vulnerability reporting obligations have applied since 11 September 2026, including for products already on the market, with the full regulation applying from 11 December 2027. For a manufacturer, this means being able to analyse, fix and roll out corrected firmware quickly.

What is the firmware engineer's role in the organisation?

The firmware engineer usually reports to the embedded software manager, the electronics engineering office manager or the technical director. They work for manufacturers of electronic equipment, connected devices, medical devices, in aerospace, defence, space, automotive, industry and in hardware start-ups.

They work closely with electronics engineers, who design the board, application software engineers, who rely on their low-level layers, and security, test and production teams.

What skills are needed to become a firmware engineer?

Technical skills

• Advanced C, often C++, sometimes Rust depending on the team.
• Microcontroller and processor architecture (ARM Cortex-M and Cortex-A, RISC-V).
• Reading electronic schematics and component documentation.
• Buses and protocols: SPI, I2C, UART, CAN, USB, Ethernet.
• Real-time operating systems (FreeRTOS, Zephyr) and embedded Linux.
• Embedded security: secure boot, signing, key management.
• Technical English for component documentation.

Soft skills

• Rigour: an error in firmware can render a device unusable.
• Tenacity in debugging, often at the boundary between hardware and software faults.
• Close collaboration with electronics engineers.

Tools and work environment

The firmware engineer works with cross-compilation toolchains (GCC, Clang), JTAG or SWD debug probes, oscilloscopes and logic analysers, evaluation boards, and, for embedded Linux, tools such as U-Boot or Yocto. Git and continuous integration with hardware test benches round out the environment.

They split their time between a development workstation and the bench, with the electronic board close at hand.

How to become a firmware engineer

The role is most often held with a Master's degree: a degree from an engineering school in electronics, industrial computing or embedded systems, or a Master's in these fields.

The most common entry paths go through embedded development, digital electronics or low-level software. Personal projects on development boards are an asset, as they show real hands-on hardware practice.

Firmware engineer salary in 2026

There is no Apec page specific to the firmware engineer role. Here are the benchmarks we have, with their limits.

Our placements. According to Bluecoders' tech and engineering salary benchmark (2026 edition, 69 permanent contracts signed between August 2025 and August 2026), the Engineering and Hardware family, which groups embedded, mechatronics, systems and industrial R&D roles, shows a median of €62,000 gross per year, with salaries ranging from €43,000 to €85,000, across 5 placements. Roles at aerospace, defence and industrial clients show a median of €64,000. Full details in our salary benchmark.

Metalworking industry minimums. At companies covered by the metalworking industry collective agreement, the UIMM publishes the 2026 minimum hierarchical salaries. An entry-level manager classified F11 has a minimum of €28,430 gross per year on a 35-hour basis, or €36,959 under the annual days-based agreement. In class G13, the minimum is €40,350, or €52,455 under the annual days-based agreement.

Three reading cautions:

• Our figures cover 5 placements, across all engineering and hardware roles combined. This is not the French market.
• Metalworking minimums are floors. The class depends on the role, and engineering consultancies often fall under a different agreement (Syntec collective agreement).
• The sector matters: defence, aerospace, medical and automotive do not share the same certification requirements.

What Bluecoders sees on this profile

Two recent placements illustrate this profile at the boundary of software and hardware. For Traak, Bluecoders recruited an embedded software engineer. For Ophelia Sensors, a senior real-time C++ developer.

For this type of role, the first question is not the title, but the target: microcontroller or embedded Linux, real-time constraints, certification, security. That is what determines which talent pool to approach.

What career paths are open to a firmware engineer?

• Senior firmware engineer, then lead firmware.
• Embedded software architect.
• Embedded software team manager.
• Embedded security expert.
• Bridges towards embedded systems engineer, real-time systems engineer or embedded software engineer on defence programmes.

FAQ

What is firmware?

Firmware is the software stored in an electronic device's non-volatile memory. It runs as soon as power is applied, initialises the hardware, drives peripherals and allows the rest of the software to run. It can be updated throughout the product's life.

What is the difference between a firmware engineer and an embedded systems engineer?

An embedded systems engineer works on the whole embedded system: components, software and integration into the product. A firmware engineer focuses on the code that boots and runs a specific board, and on its maintenance after shipment. In many companies, the two titles overlap.

What is the difference between a firmware engineer and a low-level engineer?

A low-level engineer develops software very close to the hardware across varied targets, including operating system kernels and drivers. A firmware engineer is attached to a given piece of hardware and its life cycle: boot, drivers, updates and security patches.

What is a firmware engineer's salary?

There is no Apec page specific to this role. Across Bluecoders placements in the Engineering and Hardware family, which includes embedded roles, the median is €62,000 gross per year, across 5 contracts signed between August 2025 and August 2026. In the metalworking industry, the 2026 minimum collective pay for a manager classified G13 is €40,350 on a 35-hour basis.

What languages does a firmware engineer use?

C remains the reference language, often supplemented with C++. Some teams are adopting Rust for its memory safety guarantees. Assembly is used occasionally for boot or critical sections, and Python serves test scripting.

What does the Cyber Resilience Act change for a firmware engineer?

The Cyber Resilience Act requires manufacturers of digital products to manage and report vulnerabilities in their products. According to the European Commission, reporting obligations have applied since 11 September 2026 and the full regulation applies from 11 December 2027. The firmware engineer is at the heart of the response: secure boot, reliable updates, fast patches.

What qualifications are needed to become a firmware engineer?

A Master's degree in electronics, industrial computing or embedded systems, from an engineering school or university. Hands-on practice on development boards, as a project or personal pursuit, is a real asset.

What career paths are open to a firmware engineer?

Towards lead firmware, embedded software architect, embedded software team manager or embedded security expert, with bridges towards real-time systems and safety-critical embedded software.
