Embedded Software Engineer

Are you an embedded software engineer who enjoys working close to the hardware? This opportunity in Cambridge could be a strong match if you have experience building firmware, programming microcontrollers, and solving challenging software integration problems.

Octagon Group is recruiting on behalf of a technology company that designs and manufactures advanced radio frequency (RF) and microwave solutions. Its products support demanding industries, including telecommunications, space, defence, and aerospace.

The successful candidate will help develop software and firmware for next-generation communication and control systems. You’ll work alongside specialists in electronics, RF, FPGA, and systems engineering, helping turn technical designs into reliable working products.

The advertised annual salary is £70,000–£80,000, and the role is listed as full-time with hybrid working. The listing also states that visa sponsorship is available, although applicants should confirm the relevant eligibility and sponsorship arrangements during recruitment.

About the Role

This position focuses on embedded software development for advanced electronic systems. You’ll write and test code that allows processors, microcontrollers, and electronic components to work together correctly.

Your work will cover several stages of product development, including software design, hardware integration, debugging, testing, and preparation for manufacture. You’ll also collaborate with engineers from different disciplines to resolve technical issues and make sure software works as intended on the target hardware.

Because the employer develops sophisticated communication and control technology, this role suits someone who can move comfortably between software and electronics. You should enjoy investigating difficult faults, understanding how hardware behaves, and finding practical solutions rather than relying on code alone.

Primary Responsibilities

If you get the job, your duties are expected to include:

• Designing, writing, and testing embedded software and firmware using C and C++.
• Developing software for microcontroller-based and processor-based platforms.
• Supporting hardware integration, board bring-up, and software debugging.
• Developing and maintaining communication interfaces such as Ethernet, SPI, I2C, and UART.
• Working with hardware, FPGA, and systems engineers to define requirements and resolve integration problems.
• Investigating software faults and system-level issues with suitable debugging and testing tools.
• Taking part in code reviews and preparing clear technical documentation.
• Supporting product development as designs progress toward manufacturing.

These responsibilities require careful testing and attention to detail. A software feature that works in isolation must also operate reliably when connected to real electronic hardware.

Qualifications and Skills

Octagon Group is looking for an engineer with relevant technical education or equivalent industry experience. Your background should demonstrate that you can develop embedded software and work effectively with electronic systems.

Important skills and qualifications include:

• A degree in Software Engineering, Electronic Engineering, Computer Science, or a related discipline, or equivalent industry experience.
• Strong programming skills in embedded C and C++.
• Experience developing software for embedded processors or microcontrollers, ideally including ARM-based platforms.
• Knowledge of bare-metal programming, real-time operating systems (RTOS), or embedded Linux.
• A sound understanding of hardware interfaces and software-to-hardware integration.
• Practical experience debugging, testing, and troubleshooting embedded software.
• The ability to work with engineers across software, electronics, FPGA, and systems teams.

Experience with embedded development is particularly important. In your CV, give specific examples of the platforms you’ve used, the software you developed, the tools you worked with, and the problems you solved.

Additional Technical Experience

Your application will be stronger if it shows that you understand the relationship between firmware and the hardware it controls. Practical experience with processor-based systems, communication interfaces, debugging tools, and product integration can help demonstrate your readiness for the role.

Experience in industries such as telecommunications, aerospace, defence, or advanced electronics may also be relevant because the company’s products serve technically demanding markets.

The published listing does not identify every preferred tool, programming environment, or hardware platform. Avoid claiming experience you don’t have; instead, describe your strongest relevant projects and explain your contribution to each one.

Job Snapshot

What’s on Offer?

1. Salary of up to £80,000 per year
The advertised range is £70,000–£80,000 annually. Your actual offer may depend on your experience, technical skills, and the employer’s assessment.

2. Hybrid working
The listing identifies the position as hybrid. Ask the recruiter how often you’ll need to attend the workplace and whether any flexibility applies to your circumstances.

3. Work on advanced technology
You’ll contribute to embedded software and firmware for communication and control systems used in technically demanding industries.

4. A multidisciplinary engineering environment
The role involves collaboration with electronics, RF, FPGA, and systems engineers. That gives you opportunities to work across different parts of a product rather than focusing on software in isolation.

5. Visa sponsorship stated in the advert
Sponsorship is advertised as available. However, this does not guarantee that every applicant will qualify or that sponsorship will be approved. Confirm the employer’s arrangements before making relocation plans.

Visa Sponsorship for International Applicants

This vacancy may interest qualified engineers who need UK work visa sponsorship because the LinkedIn advert explicitly states that sponsorship is available.

Still, don’t assume that the advertised support automatically covers every nationality, experience level, or personal circumstance. Ask the recruiter whether the employer can sponsor your specific application and which UK immigration route would apply.

If you’re applying from outside the UK, prepare your degree certificates, an up-to-date CV, and clear evidence of your embedded software experience. Be ready to explain your technical contribution to past projects and how your skills match the advertised requirements.

Before accepting an offer, confirm the salary, work location, hybrid arrangement, sponsorship process, and any conditions attached to the role. Never pay an individual who promises to guarantee a job offer or visa approval.

Who Should Apply?

This vacancy is best suited to engineers who already have practical embedded development skills and can demonstrate experience working with processors, microcontrollers, and electronic hardware.

Consider applying if you:

• Have strong embedded C/C++ programming skills.
• Have developed or tested firmware for real hardware.
• Understand embedded platforms, hardware interfaces, and debugging.
• Can work effectively with software and electronics specialists.
• Want to contribute to advanced communication and control products.
• Meet the role’s technical requirements and want to explore the advertised sponsorship option.

When preparing your CV, focus on relevant projects and measurable results. For example, explain which microcontroller you used, what you programmed, how you tested the system, and how you diagnosed or fixed a difficult issue.
