We are rebuilding the energy transaction, making it transparent and fair.
Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our
century, access to low cost electricity.
tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s
electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users -
businesses and generators.
We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology
is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy
transactions at scale.
In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation
from Albion, Atomico, Allianz, Hitachi Ventures, Hitachi Ventures, Schroders Capital and others - positioning us for global
expansion, deeper product innovation and category leadership.
We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets
worldwide.
Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in
energy transaction value, proving that modern software and AI can transform an industry built on legacy systems.
At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency,
efficiency and sustainability become the default, not the exception.
We’re looking for Tech Leads to accelerate product delivery and enable scale across our customer acquisition, customer success and
developer experience platforms. You’ll contribute through hands-on coding, drive architectural direction, and raise the technical
bar across the team.
In your first 12 months, you’ll lead the development of systems that redefine how brokers, customers, and internal teams interact
with energy services - from real-time pricing workflows to intuitive self-serve tools. You’ll help us launch new products that
streamline onboarding, improve service transparency, and lay the groundwork for rapid, sustainable growth.

INTRODUCTION SUMMARY We are on the lookout for a talented and ambitious Technical Specialist/Lead to join our Security and Defence, Systems and Technology team here in Cambridge, UK. The role is within the Defence & Security Business Unit that undertakes the development of innovative new products across the entire product life cycle. The role will be primarily technical development for our defence and security clients within UK government, although there will be scope to get involved in a variety of projects for our commercial and wider public sector clients. Projects typically consist of early concept work, through prototype manufacture, to new product introduction, often surmounting considerable technical challenges as we push the boundary of what is possible. We combine highly creative lateral thinking with excellent technical skills and we’re looking for broad defence and security industry experience to help us form powerful development teams. WHAT WE CAN OFFER We can offer you variety, and the chance to work in a dynamic environment buzzing with the excitement of innovation that is having a real effect on people’s lives. The projects you will be involved in will typically be highly complex, spanning the entire product development lifecycle. You will take responsibility for delivering the technical aspects of a project or workstream, working within multi-disciplinary teams of talented engineers, scientists, and designers in delivering novel products and services to market for a wide variety of clients. You will always have the support of experienced Programme Managers and Technical Authorities ready to guide you towards more complex projects as your career develops. We believe that a supportive environment is the way to bring the best out of each other. We will actively promote your progression and provide you with the opportunity to take on increasingly challenging tasks.

DEFENCE & NATIONAL SECURITY RF COMMUNICATIONS LEAD MAIN PURPOSE OF THE JOB Radio communications is at the heart of much of what Cambridge Consultants does, and in this role you will be joining an established team of commercial and technical leaders working with clients delivering projects into the Defence and National Security sector. In this market we architect a range of both standards based and fully custom radio systems for a wide range of applications including low power long range systems and highly flexible high-performance software defined systems. Our work involves significant collaboration with clients, working together to help innovate the best approach to what can be very challenging requirements. In the early stages of a client engagement, we need to be ambitious and bold, we need to think laterally, apply system design and modelling skills and embrace early experimentation and field measurements, if useful. Overall though, we need to quickly work through the challenges and create a plan to deliver the client the most impactful solution in the most efficient way possible. To do this well, the successful applicant needs to have strong and broad radio communications experience, enjoy spending time client facing, have imagination and most importantly have a strong “can do” attitude and preferably sector experience. You will often work with our account managers to define work programmes and our commercial approach to help win work. You will be able to work on your own initiative and develop programmes of work from early stage to deployed capability. Developing key client relationships and repeat business built on trust is the cornerstone of our commercial approach and your responsibilities will include an important element of client management during project delivery. RESPONSIBILITIES * Be a strong subject matter expert in the field of RF communication systems * Work with our broader team to provide input to bids and delivery of projects * Maintain strong technical relationships with key individuals within client and potential client organisations to enable further sales opportunities * Interact with teams across the whole of Cambridge Consultants to bring the best technology to our clients to solve their problems You will also use your strong technical skills to communicate what Cambridge Consultants can deliver to potential clients. Your background skills will also help you to make a significant contribution to the overall direction of development projects, often working on multiple projects at a time. Our technical team is based in Cambridge and there will be significant travel in the UK. MINIMUM REQUIREMENTS This role is for an experienced radio communication system engineer who has a strong understanding of: radio propagation, radio system design, protocol design and radio system implementations. You will play a leading role in a team of technical and advisory colleagues to solve the client’s problem. This is a technical delivery role for somebody with great client facing skills. Your career will already have included significant experience in an R&D or design role. You will probably also have had some exposure to the commercial side of projects. Previous experience of working in a consultancy, government agency or other ‘fee for service’ organisation would be an advantage. To meet the requirements of this role you will have: * Excellent radio engineering skills and experience * A passion for innovative technology solutions and for solving complex problems * An understanding of what’s important to our clients * Experience working with clients in the UK Defence & National Security sector TYPE OF WORK UNDERTAKEN BY BUSINESS UNIT The Defence and Security Business Unit specialises in the design and development of innovative solutions for specific client needs. Often projects start with requirements analysis of complex issues informed by our collective domain knowledge and evolve through technology to develop prototype manufacture and long-term delivery of equipment and services. The projects always incorporate considerable technical challenges. We work across the lifecycle, from research to deployment. Our workforce has broad expertise in the fields of Artificial Intelligence, sensing and data analytics & signal processing as well as radio frequency engineering, analogue electronics, embedded and high-level software development, mechanical design, physics and mathematics so we can and do develop complete systems for clients. Communications – and especially secure communications – are central to what we do. Our teams build bespoke communication systems for a wide range of applications, sometimes based on industry standards and sometimes custom from the ground up. Likewise, radio systems for force protection is a major area, and our experience extends to systems that support people working to defuse Improvised Explosive Devices (IEDs) in the field today – and we are working on future solutions to counter ever-changing threats. WHY CAMBRIDGE CONSULTANTS? Cambridge Consultants creates exciting and novel breakthroughs in technology and products. We help our clients achieve the kind of game-changing leap forward that will transform their whole business. At the heart of what we do are talented and motivated multi-disciplinary teams empowered to create cutting edge technologies and systems to solve difficult problems for our clients. We recognise and celebrate individual talent and we understand the importance of letting individuals be just that. Our people are here to do the best work of their lives and our job is to provide the platform for them to do it. ---------------------------------------------------------------------------------------------------------------------------------- By submitting an application to Cambridge Consultants, you confirm that the information provided in this application, together with any supporting documentation, is true, complete, and accurate to the best of your knowledge and belief.
