About the company
Our client is a UK B2B SaaS platform for property-investment businesses. Its customers source residential properties for investors, negotiate deals and earn a fee, and the platform helps them find opportunities, manage clients and deals, and market themselves. With around 60 paying customers on a white-labelled GoHighLevel setup, the team is now rebuilding the product from scratch as its own platform, with property search, deal management, portfolio tracking, financial calculators, Claude-powered AI features and Stripe billing.
The role
You’ll be the company’s first engineer and technical lead. You’ll own how the platform is built: the data model, security, payments, background jobs, integrations, and what is safe to go live. Your first big milestone is launching the new platform and moving 60 customers off GoHighLevel without losing data.
You’ll work alongside the product founder, who builds every day using Claude Code. Your job is to guide him, not replace him: shape his briefs, catch risks early, and make sure his work and yours don’t collide. A part-time QA analyst tests every release.
