The Opportunity

Brightflag is the platform that the world's leading legal teams trust to manage billions of dollars in legal spend. Our product sits at the intersection of complex data, enterprise SaaS, and AI — and the frontend experience is central to how our customers understand and act on that data every day.

You’ll be joining a strong engineering culture where frontend is a first‑class discipline. Architecture decisions aren’t handed down — they’re made collaboratively, and your voice will count. You’ll work alongside talented Product Managers, Designers, and backend engineers who care deeply about craft and outcomes. This is the kind of team where people are excited about what they’re building, and it shows in how they work together.

AI‑assisted development isn’t a future ambition here — it’s how the team works right now. Tools like Claude Code are part of the daily workflow, and we’re actively investing in AI harness engineering as a core competency. If you’re already using AI coding agents at the frontier of what’s possible, and you want to do that inside a scaling product company with real complexity and real customers, this is a rare opportunity to be in the right place at the right time.

What You Will Be Doing

• Taking features from loose requirements all the way to production. You’ll work with Product and Design to shape the problem, then design, build, test, release and run the solution in React and TypeScript.
• Building and maintaining Brightflag’s web application, writing code your teammates are glad to build on and making the features you own more reliable over time.
• Designing solutions for medium‑sized features independently, backed by a lightweight design doc or ADR for anything non‑trivial.
• Contributing to frontend architecture decisions and introducing patterns that the rest of the team picks up and reuses.
• Owning what you ship once it’s live: responding well when something goes wrong, contributing to post‑incident analysis and closing out the follow‑up actions.
• Using AI‑assisted development tools like Claude Code as a core part of how you work, and helping the team sharpen the skills, instructions and scaffolding that make those tools more effective.
• Helping the team get better through code reviews, sprint planning, onboarding new joiners and improving our tooling.

Skills & Experience

To be successful in the role, you need:

• 3+ years of hands‑on experience in a frontend role, with strong proficiency in React and TypeScript.
• Experience with state management and familiarity with testing frameworks, so quality is built in from the start rather than added at the end.
• A good eye for UI/UX and the product sense to know what will genuinely be useful to our customers.
• The ability to take a loosely defined problem and design a sound solution for it, with a clear written rationale for the decisions you make.
• Heavy, current hands‑on use of AI coding agents (e.g. Claude Code, Cursor), with AI‑augmented development as a core part of your daily workflow.
• Experience with AI harness engineering, including skills, instructions and agent scaffolding.
• A collaborative approach and a product mindset.
• A sense of ownership for your work, from first commit through to how it behaves in production.
