Job description

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.

The Technical Operations team makes Toast's engineering measurable. We connect tool and resource usage, engineering metrics, and customer outcomes into a single, trusted picture that executives, engineering managers, and developers use every day. If you are passionate about turning complex business and engineering processes into something teams can actually see, so they can spot bottlenecks and opportunities before they become major problems, use resources wisely, and ultimately deliver a better customer experience, this team is for you.

We are a small, highly leveraged team. We index heavily into agentic engineering: AI agents are part of how we design, build, test, and operate our systems, and we expect you to push that frontier with us.

A Day In The Life (Responsibilities)

• Serve as the team's technical lead, owning the end-to-end architecture and direction of our services, internal tools, and data systems, and driving significant projects from design through rollout
• Design and build the backend services and integrations that ingest engineering, tooling, and cost signals from multiple source systems, with clear APIs and data contracts rather than manual extracts
• Partner with our Product Owner to identify and define the biggest opportunities for impact, and collaborate with your teammates on end-to-end solutions
• Build the back-end that enables role-based reporting on engineering health, AI and tooling spend and ROI, and cost and capitalization, replacing recurring manual processes with durable, auditable, productized tools & analytics
• Own quality, reliability, and operational monitoring for business-critical reporting that leaders at every level depend on
• Mentor less experienced engineers and up-level the team through design reviews, constructive feedback, and agent-assisted engineering practices

What You'll Need To Thrive (Requirements)

• 5+ years of software engineering experience designing, building, and operating production full-stack systems, including data-intensive systems that automate manual business/operational processes.
• Proven ability to drive significant projects to completion from design to rollout, informed by solid technical and business understanding, working with non-engineering stakeholders
• Proficiency in at least one modern programming language (for example Python, Kotlin, or TypeScript)
• Demonstrated, hands-on use of agentic engineering as a core part of how you work
• Strong backend, API integration, SQL and data modeling skills
• Proficiency in a modern web front-end stack sufficient to prototype visualizations, and review front-end work
• Ownership of the full lifecycle of what you ship from design reviews to automated testing, monitoring, and production support
• This is a hybrid role where you will be based in the Dublin office two days per week**
