GTM Engineer

GTM Engineer

London (Hybrid, 4 days in-office) | Full-time | Up to £160K + equity | Reports to founders

No visa sponsorship. You must already have the right to work in the UK.

We're a fast-growing AI company in London hiring a GTM Engineer: a technical builder who creates the systems the business runs on, starting with sales and marketing.

This is engineering pointed at go-to-market, not pre-sales, so no demos and no integration docs. You're automating functions that currently run on manual grind. Start with revenue (lead gen and pipeline, so sales opens each day with prioritised, ready-to-act data), then extend the same playbook to marketing and beyond.

You'll sit next to the people you're building for. Watch the real workflow, ship something rough in days, harden what earns its place. Claude and Claude Code are daily tools; you'll wire things together over MCP and APIs, writing code where code's the right call.

What you'll build:

• The definitive picture of the market: who, who decides, what changed this week
• Automated sourcing, enrichment, deduplication and scoring, so sales works a prioritised list, not a spreadsheet
• Automated selling admin: briefs, CRM hygiene, follow-ups, proposals, reporting
• Inbound capture end to end, in minutes not days
• Reporting the Growth Lead and founders actually trust
• Automation for the next expensive manual process, whether that's onboarding, CS, finance ops, or hiring

What you'll bring:

• Real developer chops: production code (Python, TypeScript or similar), comfortable with APIs and databases
• 2-5 years' experience, any background, as long as the skills are there
• A strong technical degree from a leading Russell Group university or equivalent
• LLMs in everything you do, plus something built beyond a prompt: agents, tool use, retrieval, an unattended workflow. Evidence, not claims
• A track record of shipping automation a business depended on
• Commercial instinct: you know a funnel, and can tell a metric moving from a metric mattering
• Comfortable in the weeds of data quality: enrichment, matching, deduplication
• High ownership, bias to shipping

Bonus points:

technical product/forward-deployed/solutions engineering, growth engineering or revenue ops, or ex-technical-founder background. Clay, Apollo, or Claude API/MCP experience. B2B SaaS sold to SMEs or non-technical buyers.

Why this role?

You're not building one feature inside someone else's product. You're building the tools that decide how fast the company takes the market. Direct line to the founders, a team small enough to see what you shipped this week, and real room to grow deeper into growth engineering or wider into owning automation across the whole company.
