Job summary

sunday is seeking a Senior Go-to-Market Engineer to build and scale the revenue engine across the US, UK, and France. You will own GTM data, enrichment, and the automation layer, partnering with Sales, Marketing, and Data to deliver scalable technical solutions and stronger seller productivity.

This hands-on role requires designing scalable workflows, APIs, and integrations, with leadership across architecture, testing, and governance. Hybrid work and a dynamic, fast-moving environment await.

Qualifications

• Real experience with Clay, or a directly comparable GTM automation or enrichment platform, and the ability to build sophisticated workflows rather than simply operate a tool.
• Strong, hands-on Salesforce experience. Commercial data governance in Salesforce is core to this role from day one.
• Experience designing scalable workflows, integrations, and operational processes.
• Hands-on technical ability with APIs, SQL, scripting, or low-code platforms to solve business problems.
• Experience partnering directly with business stakeholders to translate ambiguous problems into practical, working solutions.
• Enough project and change‑management discipline to scope, document, test, and stage a rollout - not just ship fast and hope it lands.

Responsibilities

• Build and own sunday's GTM data and enrichment engine - connecting regional data providers, enrichment platforms, AI, and internal data to maintain an accurate global account and contact universe across our markets.
• Use AI and enrichment to make our commercial data more intelligent and actionable, filling gaps in account and contact data, identifying and validating businesses, and helping sellers understand which accounts to prioritize and why.
• Design and build the automation layer behind our core GTM motions, including inbound lead processing, outbound prospecting, enrichment, scoring, routing, seller workflows, and other high-volume commercial processes across the US, UK, and France.
• Help lead the practical application of AI within Revenue Operations, identifying high-value use cases and building AI-enabled workflows, agents, and tools that improve seller productivity, decision‑making, data quality, and operational efficiency.
• Partner with Sales, Marketing, Revenue Operations, Data, and Systems to turn commercial problems into scalable technical solutions, from initial solution design through prototyping, testing, deployment, and iteration.
• Help shape how commercial data is structured and governed in Salesforce, partnering closely with our Systems team to ensure the workflows and intelligence we build sit on a reliable data foundation.
• Build reusable integrations and technical patterns across our GTM stack, using APIs, orchestration platforms, automation tools, and code where appropriate rather than relying on manual processes or one‑off solutions.
• Act as a senior technical leader within our growing GTM Engineering capability, establishing strong engineering practices across architecture, documentation, testing, governance, and delivery while mentoring other Go-to-Market Engineers.
• Continuously evaluate emerging GTM and AI technologies, rapidly prototyping where there is a credible business use case and helping sunday determine what should become part of our long‑term commercial technology stack.
