Lead GTM System Builder

GTM at Mews runs on Salesforce, HubSpot, Nue, Databricks and Gong, and a lot of the work between those systems is still manual. This role owns the answer to a question that did not exist as a job a year ago: can we build this with AI instead of buying another tool. It is the first role of its kind at Mews, with no playbook to inherit and no predecessor to follow.

You will sit close to GTM teams, understand how they actually work, and ship production automation that removes manual steps from the commercial stack. You report into ITS during the transition and will move under the GTM organisation once the role is established, working closely with GTM leadership from day one. This is IC5, the most senior individual contributor level at Mews, and it is a pure IC track with no path or expectation into people management.

What you would do

Meet with GTM teams to understand their processes firsthand, then design and ship automation that removes real manual work

Own delivery end to end: no PM, no handoff, you scope, build, and validate what you ship

Travel to local offices when deeper embedding is needed, build alongside the team for a few days, and train them on what you shipped

Architect systems that integrate with Salesforce, HubSpot, Nue, Databricks and Gong, with security and reliability built in from the start

Work as the connective layer between engineering rigor and commercial reality, translating GTM problems into production-grade AI systems

AI Fluency Level 4: this role is built around it. You will design and ship AI-powered systems that GTM teams depend on for real commercial outcomes, not internal prototypes. That means making engineering decisions about model choice, agent design, and RAG pipelines the same way you would about any other production system, and taking full ownership of what happens when it is live.

What you would bring

5 to 7+ years of engineering experience at Tech Lead, Staff, or Principal level, with a track record of owning a technical domain end to end at a company between 100 and 2,000 people

The last 6 to 12 months spent heavily on AI: building agents, shipping AI-built systems to production, with concrete proof of impact rather than demos

Genuine fluency with LLM APIs, agent frameworks, RAG pipelines, and MCP integrations, as an active practitioner rather than an occasional user

Deep engineering judgment: you can validate AI-generated code, reason about security and architecture, and are comfortable in any language rather than tied to one tool or platform

AI Fluency Level 4 or the equivalent hands-on experience shipping AI-powered systems into production

Nice to have

Some Salesforce or CRM engineering experience, beyond admin or low-code configuration

Familiarity with the GTM stack: HubSpot, Nue, Databricks, Gong, Clay

Comfort working directly with RevOps or sales ops stakeholders without needing a translator
