The next step is to speak to Jack.
Job Title
Full Stack Software Engineer
Salary
£80k-£95k + Equity
Company Description
About:Energy is a London-based battery software company backed by three leading VCs from Europe and the US, building The Voltt—a flagship SaaS platform used by global automotive OEMs and aviation leaders to accelerate electrification and decarbonisation through high-precision battery measurement data and advanced modelling tools.
Job Description
You will lead software engineering at About:Energy, owning a production multi-tenant SaaS platform while building next-generation AI and agentic capabilities. Working closely with the founders, you will manage production reliability, design new LLM-driven features, and shape the future of the engineering team as the company scales its revolutionary battery data infrastructure.
Location
London, UK
Why this role is remarkable
Lead the transition from prototype to production for cutting-edge agentic AI capabilities within the revolutionary battery technology sector.
Join a high-growth startup backed by top-tier US and European VCs and mentored by former executives from the world's largest tech companies.
Impact the development of the world's fastest EV and support global industries in their mission-critical transition to cleaner energy systems.
What You Will Do
Own the reliability and performance of a production SaaS platform built on Next.js, Go, and AWS serverless infrastructure.
Design and ship new AI and agentic features, taking them from initial prototype through to live production for global enterprise customers.
Act as a trusted technical partner to the founders, shaping engineering best practices and advising on the future growth of the team.
The ideal candidate
Senior full-stack expertise in TypeScript and React with a proven track record of owning production SaaS platforms for paying customers.
Strong technical depth in AWS serverless environments and relational database management, including schema design and safe migrations.
Professional fluency in AI-assisted development tools and experience integrating LLMs, prompt design, and agentic workflows into production features.
Who are Jack & Jill?
Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.
And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.
How does this work?
Jack's an AI agent for job searching and career coaching. He works for you.
Jill is the AI recruiter working for the company. She recruits from Jack's network.
If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.
We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
