GTM Engineer - Ably

At Ably, we're powering the realtime revolution, delivering billions of messages for millions of devices every day for organizations like Harness, EA, Panasonic, and HubSpot.

About this role

As our Go-to-Market Engineer, you'll be the person who actually builds and owns the systems that make our commercial data and workflows trustworthy, sitting at the intersection of Sales, CS, Marketing, and Data Engineering.

You'll spend most of your time putting infrastructure in place: workflows, data pipelines, AI-driven enrichment and automation. The rest goes into using that infrastructure to find what's actually wrong and fix it: data quality audits, funnel and conversion analysis, and diagnosing gaps in our commercial systems wherever they show up.

Day to day, you will

• Build and own the systems, not just the outputs: The majority (~70%) of this role is building automated workflows, data pipelines, lead scoring and routing logic, and AI-driven enrichment across our CRM, sales, and marketing stack. The other ~30% is using what you've built to run data quality audits, diagnose conversion issues, and analyze performance.
• Automate and fix broken workflows: Address gaps wherever they appear across prospecting, outreach, data hygiene, or email delivery rates.
• Share HubSpot's day-to-day upkeep: Participate in the team's rotation for Marketing Hub and routine maintenance.
• Run data quality audits: Validate enrichment accuracy, spot-check account/lead classification, and investigate metric shifts.
• Own conversion and funnel tracking: Map drop-offs from first touch through to deal and turn insights into actionable improvements.
• Be the connective tissue between commercial and data teams: Translate stakeholder requirements into working systems.
• Use AI to operate at scale: Build AI-assisted enrichment and automation workflows unsupervised using tooling like MCP connections and LLMs.

We'd love to talk if you have

• Experience in Marketing Ops, Sales Ops, Revenue Ops, or a similar cross-functional systems role.
• Comfort working across CRM platforms (HubSpot, Salesforce, etc.).
• A track record of building things independently without being told how.
• Hands-on experience with workflow automation tools (n8n, Zapier, Make).
• Built with LLMs beyond basic prompting (agentic workflows, custom AI tooling, MCP connections).
• A systems-thinking mindset and genuine analytical ability.
• Comfort with ambiguity.

Bonus points if you have

• Familiarity with the Claude stack specifically (Claude Code, Claude API, MCP).
• Experience with lead lifecycle/funnel models (MQL, SAL, PQL, SQL).
