Job description

AI-Enabled Frontend Developer

We're looking for an AI-Enabled Frontend Developer to join HydraB in Oxford, building the web apps and internal tools our teams use every day. If you love getting a working prototype in front of real users within days, and you use AI tools to build faster without switching your judgement off, this one's for you.

THE CONTEXT

The UK's zero-emission transport sector is being built right now. HydraB is at the centre of it - developing the vehicles, hydrogen infrastructure, power systems and energy services that move decarbonisation from ambition to operational reality across bus, coach, fleet and energy markets.

We're building a digital and energy platform for fleet electrification, connecting vehicles, chargers, energy systems and operational data across UK transport. It runs on Microsoft Azure, with Snowflake and Fabric underneath. There's a lot of valuable data, and a lot of teams who need better tools to use it. That's where you come in.

THE ROLE

This is a hands-on frontend role that sits close to the business. You'll work directly with operations, engineering, commercial and fleet teams across the Group. You'll find out what they actually need, put a clickable prototype in front of them fast, and turn the ones that prove their worth into production apps they rely on.

AI coding tools like Claude Code and ChatGPT are a core part of how you'll work. They make you faster, but they don't replace your judgement. You'll know what good looks like, spot when generated code is wrong, and take ownership of what goes live.

Reporting to the Head of Digital, this is an individual contributor role. We can offer it as a permanent position or a 6-month contract, based in Oxford on a hybrid basis

WHAT YOU WILL ACTUALLY DO

• Sit down with internal teams, ask the right questions and work out the real requirement - which often isn't the one first asked for
• Turn those conversations into clickable prototypes quickly, put them in front of users and keep improving them based on what you learn
• Build the prototypes that prove their worth into secure, maintainable, production-quality web apps on Azure
• Create interfaces over our operational data - vehicles, chargers, energy and fleet data in Snowflake and Fabric
• Build reusable components, templates and AI workflows (prompts, skills, MCP integrations) so each build is faster than the last
• Manage work across several internal customers, set sensible priorities and be clear about what can and can't be delivered
• Help colleagues use AI-assisted development well, through pairing, demos and clear write-ups

YOU'LL BE A GREAT FIT IF YOU

• Have 3+ years of commercial frontend development, with production apps you've shipped and supported
• Have strong modern frontend skills - TypeScript, React (or similar), HTML/CSS, accessibility, responsive design and API integration
• Use AI coding tools daily on real projects, and have a clear view of where they help and where they don't
• Have worked directly with non-technical stakeholders or clients - gathering requirements, managing expectations and saying "not yet" when needed
• Can explain a technical trade-off to an operations manager and a design decision to an engineer
• Are a self-starter who can take a loose brief and come back with something concrete
• Care whether the thing gets used, not just whether it works

NICE TO HAVE

• Azure experience - Static Web Apps, Functions, Entra ID authentication
• Snowflake, Microsoft Fabric or other data platforms, plus dashboards and data visualisation
• Experience building MCP servers, Claude skills or agentic workflows
• UX skills - Figma, user research, usability testing
• A background in internal tools, consultancy, agency or in-house product teams
• Transport, energy or fleet sector experience

SHOW US WHAT YOU'VE BUILT

For this role, we care more about what you've built than how your CV reads. When you apply, please include:

• A link to something you've built - a live app, GitHub, a portfolio or a short video. Tell us which part was yours.
• A short paragraph about a time you took a vague request from a non-technical person and turned it into something they used. What did they ask for, what did they actually need, and how did you find out?

A CV is still useful for context, but it's not the first thing we'll look at.

THE INTERVIEW

No whiteboard. One of our internal customers gives you a short brief and time to question them, then you build a prototype using whatever AI tools you normally use. Afterwards we'll talk it through together - what you asked, what you built, what you'd do next and what you'd check before it went live.

WHAT WE OFFER

• Pension - up to 8% employer contribution
• Private medical & dental
• 25 days holiday + bank holidays, with buy & sell flexibility
• Life assurance - 4x basic salary
• Income protection
• Electric car salary sacrifice scheme
• Cycle to Work scheme
• Critical illness cover
• Employee referral bonus
• Employee Assistance Programme - 24/7, 365 days
• Retail discounts & cashback via Fizz Benefits
• Eyecare vouchers - Specsavers
