Company Description
LightWork AI is a London-based startup building Felicity, an AI-powered front desk for UK estate agents that handles 90% of incoming enquiries 24/7.
Job Description
As a GTM Engineer at LightWork AI, you will build the mission-critical systems that power the company’s commercial engine. Moving beyond manual workflows, you’ll leverage LLMs, Claude Code, and agentic frameworks to automate lead generation, pipeline management, and marketing operations, directly impacting revenue growth alongside the founding team.
Location
London, UK
Why this role is remarkable
- High-impact engineering: You aren't building product features; you are building the automated engine that determines how fast the company scales and dominates the UK market.
- Cutting-edge AI stack: Work daily with Claude, Claude Code, MCP, and agentic workflows to solve real-world business bottlenecks in a high-velocity environment.
- Direct founder collaboration: Join a lean, revenue-generating team with ISO 27001 certification and SOC 2 compliance, working 4 days a week in the London office.
What You Will Do
- Architect and maintain a definitive data picture of the UK agency market, automating sourcing, enrichment, and scoring to provide sales with a prioritized daily list.
- Build end-to-end inbound capture systems and marketing automation tools that handle lead routing and first response in minutes rather than days.
- Identify and automate expensive manual processes across the entire business, including onboarding, customer success, and finance operations, using internal tools and agentic workflows.
The ideal candidate
- 2-5 years of experience with production-level Python or TypeScript, including deep comfort with APIs, databases, and building automations a business depends on.
- Proven expertise in LLM integration, going beyond simple prompts to build autonomous agents, retrieval systems, or complex unattended workflows.
- Strong technical background with a degree from a Russell Group university or equivalent, combined with a sharp commercial instinct for sales funnels and metrics.
