Senior Software Engineer - Reporting

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.

We are hiring a Senior Software Engineer to join the Reporting Experience team in Dublin. The Reporting Experience team owns the reports restaurant operators use every day to run their business.

As a Senior Software Engineer, you will build and evolve the services that generate those reports, making sure every number an operator sees is correct, fast and explainable, from a single location to large multi-location groups.

A day in the life (Responsibilities)

• Design, build and run backend services in Java / Kotlin that define, generate and deliver reports
• Build new reports and metrics end to end, from the query to the API to the page and the export, working with Product and Design
• Investigate and fix data discrepancies raised by customers and support, digging through code, logs and data to find the root cause
• Own correctness: cover report logic with automated tests and add the monitoring and alerts that catch regressions before customers do
• Improve the performance and reliability of report generation as data volume and customer size grow
• Evolve the agentic framework to be more complete and accurate
• Use AI tooling as a genuine part of your workflow, not an afterthought

What you'll need to thrive (Requirements)

• 5+ years of professional software development, building backend or distributed systems
• Proficiency in Kotlin, Java or another object-oriented language, with solid instincts around testing and code quality
• Strong data analytics skills, and comfort reasoning about how data is aggregated and why two numbers don't match
• Experience operating production services: observability, debugging incidents, and safe rollouts
• The ability to take an ambiguous problem, break it down and drive it to completion with little oversight
• Strong communication and problem-solving skills, and curiosity to learn the restaurant domain
• Experience building data analytics agents or AI skills is a bonus
• Experience with OpenSearch is a bonus

**This is a hybrid role requiring in-office collaboration two days per week in our Dublin office.**
