Senior Principal Software Engineer, GTM

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy.

GTM Experiences defines how Toast engages with, supports, and grows customers across their entire lifecycle. This organization brings together Onboarding, Support, and Product-Led Growth (PLG) into a unified group responsible for designing and delivering a cohesive, end-to-end customer experience powered by intelligent systems and agents.

This team builds the platforms and experiences that shape how customers discover value, get started, receive help, and expand their use of Toast. We operate at the intersection of customer experience, agent experience, and product experience, developing systems that enable seamless transitions across lifecycle stages and channels.

GTM Experiences owns a broad ecosystem that includes customer onboarding journeys and activation systems, product-led growth surfaces and in-product engagement, customer support experiences and agent tooling, communications and engagement infrastructure, and AI-powered and agent-assisted lifecycle capabilities.

As Toast continues to grow, we are reimagining the customer lifecycle as a connected, intelligent platform rather than a set of siloed experiences. GTM Experiences plays a critical role in defining how these systems come together to deliver consistent, scalable, and high-quality experiences from first touch through long-term success.

About This Role

We are building the Customer Experience Platform that will define how Toast engages, supports, and grows customers at scale.

As a Senior Principal Engineer for GTM Experiences, you will serve as the LOB-level technical leader responsible for defining and driving the multi-year strategy that shapes how Toast delivers experiences across onboarding, support, and product-led growth. You will translate business strategy into coherent technical direction, align engineering investments with measurable customer and operational outcomes, and guide the architectural evolution to create a seamless customer journey.

This role extends beyond ownership of individual systems or services. You will help define how lifecycle stages connect into a unified experience and drive platform level decisions that unlock business outcomes. You will help define how core components of the support ecosystem — including AI-assisted capabilities, contact center infrastructure, agent tooling, and customer-facing support experiences — work together as a unified platform. You will partner closely with engineering, product, design, Care, Onboarding, and Growth leadership to establish a shared technical vision, make high-impact architectural decisions, and ensure that our platform scales with increasing complexity while improving customer outcomes.

Success in this role requires strong systems thinking, platform design expertise, and the ability to operate across organizational boundaries. You will bring clarity to a complex ecosystem, drive alignment across teams, and ensure our investments translate into measurable improvements in customer activation, retention, and support quality.
