Location: London, England, GB

On-Site | Full-time

Compensation: £110K - £150K GBP

Our client is a high-velocity, London-based applied research lab reshaping the future of B2B operations and sales. By building highly intelligent, agentic workflows and automating high-volume execution, they empower businesses to focus on deep, high-value human connections. Operating as a talent-dense, seed-stage, revenue-generating startup, the team ships to production daily, tackles highly ambiguous engineering challenges, and works at the cutting edge of AI capabilities.

They are seeking a Staff Engineer to serve as one of the most senior Individual Contributors (ICs) on the engineering team. In this player-coach role (~70% IC, ~30% technical leverage, mentoring, and architectural leadership), the successful candidate will not simply execute tickets, but will instead own complex, ambiguous problem spaces end-to-end.

This is a fully on-site role based in Piccadilly, London, designed for a builder who thrives in a fast-paced, highly collaborative, and high-standard engineering culture.

Key Responsibilities

The Platform team is the foundation of GoMining’s ecosystem. It owns the services that every product depends on — custody, KYC, compliance, core application components, and platform reliability.

As Head of Platform, you will own this domain end-to-end. You will define the platform strategy, lead a cross-functional engineering organization, establish engineering standards, and ensure the platform remains secure, scalable, and highly available.

This is a hands-on leadership role requiring a combination of technical expertise, product ownership, and operational excellence.

Responsibilities

Platform Ownership

• Own the Platform domain as an internal product serving multiple product teams.
• Define the platform strategy, roadmap, priorities, and success metrics.
• Drive platform scalability, reliability, and engineering excellence.

Custody & Financial Infrastructure

• Own custody infrastructure, including Fireblocks, Uphold, and similar providers.
• Ensure secure asset storage, withdrawals, deposits, and fund movements.
• Improve operational reliability across wallet infrastructure.

About LawnStarter

LawnStarter is the nation's leading on-demand marketplace for lawn care and outdoor services, with over $100M in annual bookings. We're expanding beyond lawn care to become the one-stop shop for all home services — operating across three brands (LawnStarter, Lawn Love, Home Gnome) on a single shared platform.

About Service Delivery at LawnStarter

We make a promise on both sides of the marketplace: customers get a job done well, and Pros get paid fairly for doing it. Service delivery is everything that happens after a customer books — keeping that promise through completion, support, and the moments when things don't go to plan.

This is the hard part of running a marketplace: we broker work we can't directly see, between two parties whose interests sometimes collide. Get it right and people stay for years. Get it wrong and you lose customers, Pros, or both. Trust is the product — and increasingly, the systems that protect it are AI-powered.

Requirements

The Role

This is a broad Senior PM role on the quality, trust, and communication side of service delivery — setting the right expectations on both sides, steering Pros to deliver great work, resolving conflicting interests fairly, and making our AI-powered support genuinely good. You'll work on live, high-scale systems with a mandate to make them better.
