GTM Engineer

Our everyday digital experiences are in the midst of a realtime revolution. Whether chatting alongside a livestreaming event, receiving realtime financial information, or working with colleagues in an online collaborative environment - consumers simply expect realtime digital experiences as standard. At Ably we’re not just witnessing this revolution, we’re powering it - at scale.

At the heart of our mission lies a commitment to putting developers first. Ably provides a suite of products to build, extend, and deliver powerful digital experiences in realtime, delivering billions of messages for millions of devices every day and supporting organizations like Harness, EA, Panasonic and HubSpot.

Working at Ably means helping to build the infrastructure and technology that will power and shape the future of the internet. The opportunity in front of us is immense. And we’d like your help.

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, not just report on where they're broken. Right now, responsibility for Ably's commercial data and workflows is split across a few people and tools, each doing good work in their own area, but nobody's holding the full picture end to end. That's what we want this person to own.

This role sits at the intersection of Sales, CS, Marketing and Data Engineering. This isn't scoped to one function: it's scoped to wherever the commercial systems gap is, whether that's a marketing lifecycle problem today or a sales automation problem tomorrow. You might build an agent that flags an ICP account the moment its usage crosses a threshold and drafts the first outreach, or a nightly job that reconciles HubSpot and Snowflake data so nobody's arguing about whose number is right.

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.

This isn't a dashboards-on-request role. You won't be handed tickets and told what to build. We want someone who thinks like an owner: you see the gap before anyone else notices it, decide what's worth building, and go build it, not because something's on fire, but because you can see a better system than the one that exists today.

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. You choose the stack and approach; we care about reliability, not which tool you picked. The other ~30% is using what you've built to run data quality audits, diagnose conversion issues and analyse performance.
