Junior Electronics Software Engineer

Junior Electronics Software Engineer – Sheffield (Hybrid) – £30,000 to £38,000

KO2’s client is looking for a Junior Electronics Software Engineer who’s more than just technically capable — they’re obsessed with solving problems. If you took everything apart as a kid (and sometimes managed to put it back together), this might be your perfect next step.

You’ll be working closely with a seasoned R&D engineer and classic hands-on tinkerer who’s built everything from PCBs to control algorithms. He is looking to pass on his knowledge before retirement, so this is your chance to learn directly from someone who’s done it all – if you’ve got the curiosity and resilience to keep up.

This hybrid role, based in Sheffield, is ideal for someone with 2–3 years of experience as an electronics engineer or embedded software engineer, a strong academic background, and a passion for solving real-world engineering challenges.

What you’ll be doing:

  • Supporting and learning from a true all-rounder who handles electronics, software, and control
  • Helping to design, build and develop video product lines used in cutting-edge systems
  • Applying your physics knowledge – especially in magnetism, electrical control, or transformers
  • Developing your skills in both embedded systems and broader R&D
  • Taking raw ideas and turning them into practical, engineered solutions

We’re looking for someone who:

  • Has 2–3 years of experience as an embedded software engineer or electronics engineer
  • Holds a strong degree in electronics, mechatronics, or a similar discipline
  • Can demonstrate a passion for building, fixing, hacking, or solving – robotics, audio, automation, whatever gets your gears turning
  • Can handle feedback and thrive in a no-nonsense, real engineering environment
  • Is eager to grow into a multi-skilled electronics engineer capable of handling everything from embedded software to PCB work

If you can show us you’ve thought deeply about systems and have the drive to keep learning, we’ll teach you the rest. You don’t need to be a finished article — we’re looking for a sharp, passionate embedded software engineer who’s ready to roll up their sleeves and absorb everything Roy knows.

This is a unique opportunity to grow into a true multidisciplinary electronics engineer. If your idea of fun includes debugging code, solving control problems, or building automated gadgets in your spare time, we want to hear from you.

Apply now and take your next step as an embedded software engineer with one of Sheffield’s most technically diverse engineering teams.

Electronic Software Team Leader

Electronics Software Team Leader – Sheffield (Hybrid) – £55,000

KO2’s client is hiring an Electronics Software Team Leader to guide a small but growing multidisciplinary team, combining embedded software know-how with real-world control design. This hybrid role, based in Sheffield, offers a fantastic opportunity to influence future technology in a business that’s moving quickly towards connected systems and smarter infrastructure.

We’re looking for an experienced electronics engineer who brings strong hands-on skills in embedded software, plus some exposure to PLC programming and practical control system design. You’ll be the go-to person for mentoring junior team members, code reviews, and setting up clear engineering processes, while still staying technically active.

The ideal candidate is someone who understands how to deliver real-world solutions – not just from a textbook – and who’s excited about shaping a team and product roadmap as we move toward more cloud-connected, intelligent systems.

Your responsibilities:

  • Lead and support a team of engineers working across embedded software and electronics
  • Design, review, and maintain embedded software for control systems
  • Review and support PLC code development, particularly structured text
  • Bring practical experience in whole-system control design – not just isolated components
  • Collaborate cross-functionally with electrical, mechanical, and operations teams
  • Establish and improve software release and quality processes

What we’re looking for:

  • A strong background as an electronics engineer with commercial embedded software experience
  • Some familiarity with PLC systems – ideally with experience reviewing or modifying code in a structured environment
  • Someone who’s built or contributed to the control design of full systems (not just programming within a narrow scope)
  • A passion for mentoring and leading other engineers – this isn’t just a management role, it’s hands-on too
  • Good communication skills, and a practical, pragmatic approach to engineering challenges

While this role has a leadership aspect, it’s also a great fit for a senior electronics engineer who’s ready to step up and shape a team. If you’ve got experience with embedded software, know your way around a PLC, and are comfortable working across hardware and software, we want to hear from you.

This is a genuinely exciting time to join KO2’s client. With support from experienced leadership and a clear vision for the future, you’ll be in a great position to build something meaningful – and bring your full skillset to the table.

If you’re an electronics engineer looking to step into a team leadership role while staying close to the code and making real impact in PLC, embedded software, and control system design, apply now.

Head of Electronics

Head of Electronics – Sheffield – Up to £80,000

Are you a hands-on electronics leader looking to shape the future of hardware in a high-impact, cross-functional role?

KO2’s client hiring a Head of Electronics to lead a growing engineering function in Sheffield. This isn’t just about setting strategy from a distance – it’s a true player-coach role where you’ll combine technical expertise with team leadership, owning both delivery and direction.

You’ll take responsibility for the hardware engineering team, currently spanning electronics, mechanical design, and testing. While the focus is on electronics, the scope is broader – you’ll be leading a multidisciplinary team, managing OKRs, setting priorities, and getting involved at the board level when needed.

This is a great opportunity for someone who thrives in fast-paced, collaborative environments and wants to take a hands-on role in both the design and the decision-making.

What you’ll be doing:

  • Leading and growing the hardware function, with a strong emphasis on delivery and quality
  • Acting as a key contributor in electronics design – testing, building, and problem-solving alongside your team
  • Managing day-to-day activity across electronics, test, mechanical, and technician functions
  • Ensuring compliance and documentation for EMC, safety, and regulatory standards
  • Bridging across software, firmware, and operations to ensure seamless product development
  • Making smart, informed decisions around integration, production, and components

What we’re looking for:

  • A strong background in hardware design, especially within complex electronics systems
  • Experience leading and developing engineering teams with a structured, hands-on style
  • A system-level mindset – comfortable aligning mechanical, software, and electronics workstreams
  • Familiarity with regulatory testing and EMC certification
  • Someone confident, collaborative, and technically credible who can get stuck in and guide others

This isn’t a role for someone looking to stay purely technical or purely managerial. We’re seeking someone who blends both – capable of setting direction but also happy to roll up their sleeves in the electronics lab when needed.

You’ll be joining at a pivotal moment, with the outgoing Head of Electronics committed to a smooth handover before retirement. That makes this a rare opportunity to take ownership of a well-established function with real momentum behind it.

If you’re ready to step into a leadership role while staying connected to the electronics work you love, we’d love to hear from you
