About ev.energy
We are building the world's largest EV-centric virtual power plant (VPP). By connecting to vehicles, chargers, batteries, solar, and other distributed energy resources, we turn households into flexible grid assets that balance supply and demand, preventing blackouts and reducing reliance on fossil fuels.
We are scaling rapidly across North America and Europe. We are moving fast, we are AI-first, and we are looking for builders who want to power the grid of the future.
About the role
Our core platform is built in Python and Django, so we're looking for experienced backend software engineers with strong Python skills; Django experience would be beneficial but we’re open to other frameworks.
You'll be the person who takes a product idea and builds the systems, services, and infrastructure that make it real — reliable, scalable, and fast to iterate on. We're not looking for generalists who dabble across the stack — we're looking for someone with deep backend craft who can move fast, build with AI as a core part of how they work, and take genuine ownership of what they ship.
We're hiring for a number of roles across both of our Technology teams: new product development and customer delivery. We'd love to talk to you about both teams, understand what excites you, and place you into the team where we think you'll thrive best.
What you'll do
Backend engineering and architecture
- Design, build, and own backend services and APIs that power our product — from data models to infrastructure to production reliability
- Make sound architectural decisions that balance shipping speed against long-term maintainability and scale
- Take ownership of significant technical areas — from identifying the right approach to shipping and iterating in production
Building and shipping with AI
- Use AI coding tools (Claude, Cursor, or equivalent) as a core, daily part of how you write and ship code — not an occasional add-on
- Build working backend prototypes fast — good enough to validate with real usage, not over-engineered before it's proven
- Know when a rough implementation is right for the moment and when production-grade engineering is needed — and apply that judgment confidently
- Ship, measure, learn, iterate — kill what isn't working, double down on what is
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Product and stakeholder collaboration
- Work closely with product, design, and commercial stakeholders to translate customer problems into technical solutions
- Act as a credible engineering voice in cross-functional discussions, pilot programmes, and technical scoping conversations
- Partner with Customer Support, Program Management, and Demand Generation to understand how customers find, adopt, and stay with ev.energy
Raising the bar
- Share what you learn openly, challenge how things are built, and raise the technical bar for the engineers around you
- Model what AI-native backend engineering looks like in practice — not in theory
- Contribute to a culture of experimentation, velocity, and commercial impact
Our tech stack
- Python and Django for our core platform
- Django REST Framework for our APIs
- React, React Native and TypeScript for our web and mobile app
- PostgreSQL, Redis and DynamoDB for data storage
- AWS for hosting, with infrastructure managed as code using Terraform
- Claude (via the Anthropic API) features to power AI
What we're looking for
Must-haves
- Strong Python experience (5+ years), with a clear track record of building and shipping production backend systems
- Experience building backend services with a Python framework (e.g Django, FastAPI or Flask)
- Strong experience building with AI — you've taken AI-powered features or products from concept through to production, and use AI coding tools (Claude, Cursor, or equivalent) as a genuine daily practice, not just occasionally
- Solid understanding of backend fundamentals — APIs, data modelling, databases, system design, and production reliability
- Experience leading technical decisions and influencing direction without relying on hierarchy
- Strong communication skills — written, verbal, and technical — credible with engineers, product, and commercial stakeholders
- High bias for action and comfort with ambiguity — you make good technical decisions with incomplete information

Your very own career expert that helps elevate your application to the next level.
Nice to haves
- Experience in energy, utilities, cleantech, or adjacent domains
- Experience with Django
- Familiarity with EV fleet operations, home energy management, or grid services
- Front-end or full-stack capability that lets you prototype independently without blocking on others
- A portfolio of backend systems, tools, or products that prove how you work
- Direct customer conversation experience that's shaped what you've built

Location & how we work
This role is fully remote in the UK.
The majority of people at ev.energy work on a fully remote basis, with a small number of roles based on-site in our testing sites.
This means that most of our people work from home, but we're happy to provide co-working subscriptions if you'd like to spend time at a WeWork (or other co-working space close to you).
We balance our remote set up by getting everyone together once a year for an offsite, as we know that spending time together IRL is super important.
