Senior Go-to-Market Engineer

About Us

sunday is building the fastest, simplest way to pay in restaurants. With a quick scan of a QR code, diners can pay, tip, and leave in about 10 seconds. We believe great products should feel obvious, not complicated, and we focus relentlessly on keeping things simple while earning trust from restaurants and guests at every interaction. Today, sunday powers payments in thousands of restaurants across the US, UK, and France, helping operators turn tables faster, increase tips, and unlock valuable insights.

We push ourselves to go beyond what’s expected, building with ownership, moving fast, and scaling with ambition as we tackle our biggest growth opportunity in the US.

At sunday, we believe Revenue Operations should operate more like a product and engineering organization than a traditional support function. Our mission is to build scalable systems, deliver solutions quickly, and continuously improve how our commercial teams operate.

We're looking for a Senior Go-to-Market Engineer to help build the next generation of our revenue engine. This role sits at the intersection of Revenue Operations, Sales, Marketing, Data, AI, and Automation. You'll partner directly with business stakeholders to turn commercial challenges into thoughtful, scalable technical solutions that help our teams move faster, make better decisions, and deliver a better customer experience.

You’ll take a senior technical role in building three core capabilities: the data and enrichment engine that powers how we understand our market, the automation layer behind our inbound and outbound motions, and the practical application of AI across our revenue organization.

This is a hands-on builder role. You’ll design and implement modern workflows, improve the quality and reliability of our commercial systems, and help establish sunday's internal Revenue Engineering capability. You’ll also provide technical mentorship to other Go-to-Market Engineers and play an important role in shaping how we build for the future.

Technology is evolving rapidly, and so are we. We’re not looking for someone who already knows every tool - we’re looking for someone who learns quickly, enjoys experimenting, and wants to help define how AI and modern automation transform the way modern commercial organizations operate. We believe Revenue Operations should be measured by the quality of the solutions it delivers, the experiences it creates for its users, and the business outcomes it enables.

This is a build role: you’ll help establish the architecture and governance that powers sunday's next stage of growth as we scale into a truly global, multi-market organization.
