About the role

Toast's standard text

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 Staff Software Engineer to join Toast Reporting Experience (TREX) in Dublin. TREX is building the Intelligence Platform: a governed data layer that brings Toast's restaurant intelligence to prospects, operators, Toast IQ and AI agents.

As a Staff Software Engineer, you will be the technical lead for the Intelligence Platform. You will establish its architecture on Toast's data lake and make the key design calls across data processing, privacy, publishing and serving. You will work closely with Data Platform, Marketing, Product, Legal and Data Science, do deep hands-on work, and grow the engineers on your team.

You will take the platform from its first version, a regular publication of aggregated benchmark data, to fresher data, self-serve access for Marketing, and eventually real-time access for AI agents. Success looks like new data products shipping on the platform quickly and safely.

A day in the life (Responsibilities)

  • Own the technical vision and end-to-end architecture of the Intelligence Platform, from early design through production rollout
  • Work hands-on with Kotlin/Java, Spark and Iceberg on Toast's data lake, writing the code that sets the pattern for others
  • Move fast from idea to proof of concept: ship early versions, get feedback from Marketing and other partners, and iterate
  • Build privacy and compliance into the platform from the start: work with Legal, Investor Relations, Privacy and Data Science to define the data-access rules and minimum group sizes, and enforce them in code so every published number is aggregated, anonymized and auditable
  • Create reusable building blocks so every data product on the platform meets the same bar for quality and safety
  • Design the flows that let tools and AI agents access the data efficiently, safely and at scale
  • Partner with Marketing, Product, Legal, Investor Relations and Data Science to turn business goals into a technical roadmap
  • Set the bar for reliability and quality, and mentor other engineers through design reviews, code reviews and the example you set
  • Use AI tooling as a genuine force multiplier in your day-to-day work and help the team do the same

What you'll need to thrive (Requirements)

  • 5+ years in software engineering, building data-intensive or distributed systems, including technical leadership of projects involving multiple teams
  • Demonstrated ability to understand complex data domains at scale, and to turn them into reliable data products
  • Proficiency in Java, Kotlin or another object-oriented language
  • Experience with cloud-native data platforms on AWS
  • Strong SQL and data modeling skills on large datasets
  • Experience building data products or platforms that other teams depend on
  • Experience handling sensitive data responsibly, such as aggregation, anonymization or access controls
  • Ability to explain technical trade-offs clearly to non-engineering partners
  • Experience with Apache Spark, Apache Iceberg, Snowflake or Databricks is a bonus

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

Our tech stack

The Intelligence Platform will source data from multiple sources: OpenSearch, Data Lake, Snowflake.

Toast's data lake is built on AWS: Apache Iceberg tables on S3 and Apache Spark for data processing. TREX's backend services are primarily Kotlin and Java, use Apache Pulsar for messaging, and serve data to other teams through APIs, including federated GraphQL.
