Work For Us
Current Vacancies
At Equisera, we believe that tackling climate change requires the brightest minds and most passionate people, working together to accelerate Net Zero. Even if we’re not actively hiring at the moment, we’re always keen to hear from individuals who share our mission to fuel a fossil‑free future.
If you’d like to be considered for future opportunities, please email your CV and a cover letter to careers@equisera.com. We’ll keep your details on file and be in touch should a suitable role become available. Due to the high volume of interest we receive, we are unable to provide individual feedback unless you are shortlisted for an interview but we genuinely value every application and the enthusiasm behind it.
Diversity, Inclusion & Fair Hiring
We are committed to building a fair, inclusive and supportive working environment where everyone has the opportunity to succeed. STEM has long been less diverse than it should be, and we want to be part of changing that – because bringing together different backgrounds, experiences and perspectives is how we solve hard problems in cleantech.
Recruitment decisions are made on skills, potential and values alignment. We actively encourage applications from people of all backgrounds and experiences, and we work to remove barriers so we can attract, support and retain the best talent.
We encourage you to apply even if you do not believe you meet every qualification listed. Strong candidates rarely meet every criterion, and research shows that people from underrepresented groups are more likely to experience imposter syndrome and to doubt the strength of their application. Please do not rule yourself out too early – if this work interests you, we would like to hear from you.
If you require any adjustments during the interview process, or have specific needs in your working style, please let us know when you apply. We will always do our best to accommodate you.
We believe in an environment where diverse perspectives are celebrated and collaboration is the norm.

About Equisera
At Equisera, you will be part of a team building the next generation of carbon-negative energy, tackling some of the hardest problems in the global energy transition.
Our breakthrough RiPR (Rising Pressure Reformer) technology converts wet biogenic feedstocks, including agricultural and food waste and even plastics, into high-yield hydrogen and biomethane with minimal pre-processing. Both outputs capture carbon dioxide and create biochar, creating a truly carbon-negative fuel solution.
Backed by significant investment and strategic partnerships, you will be joining us at a critical scale-up phase. You will work within a small, passionate, high-impact team and help shape a cleaner, greener energy future.
The Role
As a Mechanical Design Engineer, you will join Equisera’s engineering team at an exciting stage in our commercialisation journey, supporting the development of next-generation carbon-negative energy systems.
You will play a key role in the mechanical design and development of prototype, pilot, and future commercial plant systems, working closely with multidisciplinary engineering and research teams. The role combines hands-on engineering with detailed design work and offers the opportunity to contribute directly to the development of pioneering clean-energy technology.
Your work will include developing plant layouts, general assemblies, detailed mechanical designs, fabrication drawings, and production of the supporting engineering documentation for process equipment and integrated plant systems. You will also contribute to engineering problem solving, equipment specification, system integration, design reviews, and continuous improvement activities across the wider engineering programme.
This is a hands-on role suited to someone comfortable operating within a fast-moving, technically ambitious start-up environment where adaptability, initiative, and collaboration are highly valued.
Training will be provided on ANSYS and other engineering software relevant to the role.
Key responsibilities:

- Produce and maintain plant layouts, general assemblies, detailed manufacturing drawings, and fabrication packages.
- Create and update 3D CAD models and associated engineering documentation.
- Support equipment integration, piping layouts, structural arrangements, and overall plant configuration activities.
- Work closely with multidisciplinary engineering, chemistry, control systems and operations teams to support technology development and scale-up.
- Assist with design reviews, engineering problem solving, and continuous improvement activities.
- Support prototype build, commissioning, and testing activities where required.
- Liaise with suppliers, fabricators, and contractors to support manufacturing and procurement activities.
- Ensure engineering documentation is accurate, controlled, and maintained to company standards.
- Contribute to safe engineering design practices and support compliance with relevant engineering and safety requirements.

Senior Process Engineer
Reporting to the Chief Engineer, you will lead Equisera’s multidisciplinary engineering design team. You will define how RiPR is engineered into safe, operable and commercially viable process plants while leading concept development, detailed design, procurement, commissioning and continuous improvement.
Location: Equisera’s purpose-built innovation campus in the beautiful Gloucestershire countryside.
Salary: Competitive salary (£60,000-£75,000+ DOE)
Contract Type: Full-time
About Equisera
At Equisera, you’ll help build one of the world’s first commercially deployable carbon-negative energy technologies, tackling some of the hardest engineering challenges in the global energy transition.
Our breakthrough RiPR (Rising Pressure Reformer) process converts wet biogenic feedstocks, including agricultural and food waste and even plastics, into high-yield hydrogen and biomethane with minimal pre-processing. The process simultaneously captures carbon dioxide and produces biochar, delivering a truly carbon-negative energy solution.
Backed by significant private investment, government innovation funding and strategic industry partnerships, you will be joining us at a pivotal stage as we deliver our first commercial-scale plant. You’ll join a small, passionate, high-impact team helping shape the future of carbon-negative energy.
The Role
Reporting to the Chief Engineer, you will lead Equisera’s multidisciplinary engineering design team. You will define how RiPR is engineered into safe, operable and commercially viable process plants while leading concept development, detailed design, procurement, commissioning and continuous improvement.
Why this role is different
Unlike many engineering roles, this is not a desk-bound design position. At our purpose-built innovation campus, engineering, laboratories and manufacturing sit under one roof, giving you the opportunity to take ideas from first principles through laboratory validation, pilot plant and ultimately commercial deployment.
Key Responsibilities
You will develop the process engineering systems that underpin RiPR as it progresses from research and development to commercial deployment.
You will oversee chemical and mechanical engineers to define process requirements; support equipment selection; ensure that decisions are supported by robust analysis and sound engineering judgement and develop integrated process plant designs that are safe, practical and cost-effective to build and operate.
The role will involve leading the design efforts, reviewing and approving designs, supplier engagement, procurement, commissioning activities and operational troubleshooting, and mentoring the junior members of the team. You will contribute to the continuous improvement of RiPR, engineering processes and standards as the business grows.
You will own the process engineering Basis of Design, leading the development of Front End Engineering Design (FEED) packages that underpin the safe, efficient and commercially successful deployment of RiPR.
