Job Specifications

Senior Software Engineer

Location: London (Hybrid / On-site)

Salary: £100,000 – £150,000 + equity

About the Company

We’re working with an early-stage, venture-backed legal technology startup on a mission to transform one of the UK’s most broken consumer experiences: the legal process behind property transactions.

This market is large, fragmented, and outdated, with high failure rates, poor transparency, and processes still reliant on manual workflows. The company is building the UK’s first AI-native law firm, starting with property transactions and scaling towards a full-service, AI-first legal platform with global ambitions.

The business is backed by a leading early-stage VC fund and experienced angel investors, and led by a founder who has previously built and scaled a regulated fintech business to multi-billion-pound lending volumes. That experience provides a strong foundation for navigating regulation while moving quickly in a traditionally slow industry.

The Role

This is an opportunity for a Staff or Senior Product Engineer to join as one of the earliest engineers in the business. You’ll be part of a small, high-calibre team of generalists who value product thinking, speed, and engineering craft.

From day one, you’ll have significant ownership, shaping product direction, shipping to production quickly, and working directly with users to define what should be built. Requirements won’t always be fully formed; you’ll be expected to explore problems, test ideas, and iterate fast.

This role reports directly to the founder and offers genuine influence over both product and technical direction.

What You’ll Do

Build and ship production features from your first week
Work closely with users to understand pain points and validate solutions
Help define product strategy in an ambiguous, fast-moving environment
Design and scale TypeScript-based systems across the stack
Build AI-powered workflows and agent-based systems that go beyond basic prompting
Set engineering standards and raise the bar as the team grows

You May Be a Good Fit If You

Have experience at early-stage startups and enjoy high ownership
Think in terms of user problems, not just technical implementations
Have scaled and maintained complex TypeScript codebases
Are comfortable working end-to-end across product and engineering
Actively experiment with and refine AI-assisted development workflows
Have built LLM-powered systems or AI agents in production environments

Tech Stack

TypeScript monorepo
React, tRPC, Tailwind
Event-driven workflows and background jobs
Deployed on Google Cloud Platform
Postgres

What’s On Offer

£100,000 – £150,000 base salary (depending on experience)
Meaningful early-stage equity
5% employer pension contribution
Private medical cover (including dental and optical)
25 days holiday plus bank holidays
Choice of AI tooling
London-based role (Shoreditch), working closely with the founding team
