Job description

Bold ideas start with bold people. At Ensera Design, we are a world‑class user‑centered innovation and product development consultancy working across medical and consumer health. Join our multidisciplinary team to build robust, secure firmware that powers life‑enhancing products.

We are currently seeking an embedded Software Engineer to join our talented team and contribute to delivering exceptional solutions for our clients.

You’ll join a multidisciplinary team developing a greenfield medical device from the ground up.

Day to day, your focus will be designing and implementing embedded software in C/C++ on embedded Linux platforms. You’ll sit alongside hardware, MCU, UI and test engineers, with real input into the Linux architecture and design while the project is still taking shape.

You’ll have a team of Senior Software Engineers around you who’ll mentor you throughout. Due to the nature of Ensera Design’s work, you’ll have the opportunity to either branch out into other specialisms or go deeper into the one you’re already in.

About you

You’re an engineer who has worked across safety‑critical systems and/or medical devices in the past with a desire to develop within an embeddedLinuxenvironment. You’ll be a strong communicator with a desire to learn from others, share your own knowledge and mentor junior engineers.

You’ll be interested in working on safety‑critical applications across the full development lifecycle and in accordance with safety and reliability standards such as IEC 62304.

What you’ll do

• Design and implement embedded Linux software in line with agreed system and security architecture
• Support Linux platform bring‑up and configuration within scope
• Contribute to the embedded build system (e.g. Yocto or equivalent)
• Define and maintain interfaces between Linux, MCU firmware, UI, and connectivity components
• Support debugging of system‑level faults and performance issues
• Share knowledge and mentor more junior members of the team

Your skills and experience

You don’t need to tick every box but if you hit most of the essentials, we’d love to hear from you.

• Around 3-5 years’ experience developing software on embedded Linux platforms
• Solid understanding of Linux internals, IPC, filesystems, and networking
• Experience with embedded build systems (Yocto, Buildroot, or similar)
• Strong C/C++ experience; scripting experience is beneficial
• Experience working in structured, quality-focused development environments
• Experience with Qt or other embedded UI frameworks
• Experience integrating Linux systems with MCUs over UART, SPI, or CAN
• Secure boot, system update, or platform hardening experience
• Experience with communication protocols (UART, SPI, I²C, CAN)
• Experience working in regulated or safety‑critical domains

Why work with us?

Ensera Design offers interesting and varied work combined with a supportive team culture to provide a stimulating environment where you will have the opportunity to develop and learn from others. We offer flexible working policies where working patterns are agreed with our line managers, taking into account the role, needs of the individual, and the team.

We recognise that we are only as good as our people and we know how important it is to support our team.

We offer:

• Performance‑related company‑wide bonus.
• Flexible hybrid working in line with our core hours (Mon–Thu, 9:30am–12:00pm & 2:00pm–4:00pm; Fri, 9:30am–12:00pm).
• Private healthcare for you and your family.
• Enhanced maternity and paternity leave.
• Salary exchange pension scheme.
• 25 days of annual leave, plus the option to purchase up to one working week and additional days for length of service.
• Access to our Employee Assistance Programme and digital wellbeing platform.
• Cycle to Work & Electric Vehicle Lease schemes.
• Death in service (x4 gross salary).
• Training and development opportunities, including dedicated learning days and regular knowledge‑sharing sessions.
• A free lunch the first Monday of every month alongside our company‑wide meeting.
• Free breakfast every Wednesday, and plenty of opportunities to socialise, including team‑organized activities, summer and Christmas parties, and more.

At Ensera Design we believe that designing for people means including all people, starting with the team behind the work. Our human‑centred design ethos is rooted in empathy, and our values – pull together, find a way, and care – guide us in building a team that reflects the diversity of the world we design for.

We know that different perspectives lead to better ideas, stronger collaboration, and more meaningful outcomes. If you meet the skills and experience for this role, we welcome your application – whatever your background, identity, or path into design. What matters to us is that you share our belief in purposeful, people‑first design.
