GTM Engineer (RevOps / SalesOps)

About Fuelius Fuelius is an Elite HubSpot Solutions Partner. We implement HubSpot CRM for scaling businesses — replacing legacy systems like Salesforce, Dynamics, and Sugar, or moving organisations off spreadsheets entirely — and we deliver Go-To-Market as a service, driving net new pipeline for our clients. When we do both together, the results are transformational. We work primarily in the mid-market and corporate space, often with PE-backed businesses that have a mandate to grow. Our buyers are revenue leaders across sales and marketing who need a partner that understands both the technology and the commercial strategy behind it. The Role This is not a role that exists widely in the UK yet. GTM Engineer is a title born out of the modern revenue operations movement — a blend of technical systems thinking, commercial awareness, and a relentless obsession with pipeline generation. You will be the engine behind our outbound machine. Your mission is to use data, automation, and intelligent tooling to generate a significant and measurable volume of qualified leads for our sales team. You will build, test, and optimise outbound campaigns using Clay, HubSpot, and a growing stack of GTM tools. You will source unique data signals, design creative outreach plays, and continuously experiment to find what we call "GTM Alpha" — the competitive edge that comes from seeing what others don't and doing what others can't. If you've never heard of GTM Alpha, look it up. It's the philosophy at the heart of this role: better data than your competitors, deployed in plays they can't replicate, with a culture of continuous experimentation that means you're always three steps ahead. What You'll Own Pipeline Generation Design, build, and run outbound campaigns in Clay that generate qualified leads at scale Source and enrich prospect data using waterfall enrichment, AI agents, web scraping, and custom signals to build hyper-targeted account lists. Identify unique data points that give Fuelius a precision edge — funding rounds, tech stack changes, hiring signals, PE investment activity, CRM contract renewals — and build automated workflows around them. Generate a measurable volume of Sales Qualified Leads and sourced pipeline, with annual bonuses tied to your output. Systems & Automation Own the outbound technology stack: Clay, HubSpot, and many other supporting tools. Build and maintain automated workflows that move prospects from signal to sequence to sales conversation. Integrate systems using APIs, webhooks, n8n, or whatever gets the job done — you'll vibe-code where needed and aren't afraid of a complex automation. Keep HubSpot CRM clean, enriched, and optimised as the single source of truth for our GTM motion. Experimentation & GTM Alpha Run a continuous test-and-learn programme: hypothesise, build, measure, iterate. Develop new outbound plays — creative, data-driven campaigns that go far beyond "spray and pray." Evaluate and pilot new tools, data providers, and AI capabilities to keep our GTM engine at the cutting edge. Share learnings with the wider GTM team to compound knowledge across sales and marketing. Our GTM Tech Stack You'll work with the following tools daily, and you'll have the autonomy to propose and pilot new ones: Clay — Our primary outbound engine for data enrichment, campaign building, and signal-based prospecting. HubSpot — CRM, sequences, and marketing automation.
