[Remote] Senior Backend Engineer (Python)

Note: The job is a remote job and is open to candidates in USA. ev.energy is building an electric-vehicle-centric virtual power plant that connects distributed energy resources to balance grid supply and demand. The Senior Backend Engineer will design, build, and own reliable, scalable Python backend services and APIs, use AI coding tools and develop AI-powered products, and collaborate with product, commercial, and customer-facing stakeholders.

Responsibilities

• 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
• 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
• 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
• 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

Skills

• 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
• This role is fully remote in the US, but we're specifically looking for someone based in EST
• 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

Benefits

• Equity - you'll own a part of the business through our share options program
• Healthcare options - to help keep you and your family in tip-top condition (provided by Cigna & Guardian)
• Life and disability insurance
• Co-working access via WeWork (if you'd like it)
• Annual 'Team Week' whole company offsite
• L&D allowance of $1,300 per year - everyone is learning, developing and challenging themselves so we have a professional development fund per year for you to learn new skills
• Fully remote in the US
