Senior Software Engineer, Toast

• Strong backend engineering skills in Kotlin, Java, or another object-oriented language, with solid instincts around testing and code quality
• Experience working with large datasets, where correctness, freshness, and query performance all matter at the same time
• Comfort with document-based or columnar data stores (BigTable, DynamoDB or similar)
• A strong interest in core search engineering e.g. ranking algorithms, semantic search, natural language search etc
• Ability to work across team boundaries and pick up context quickly - OLAP touches almost every product area at Toast, and the work can be as much collaboration as execution
• The ability to break down a problem, understand what the consuming team actually needs, and ship a clean solution. Our users are other engineers, and the ergonomics of the platform matter
• Use AI tooling as a genuine part of your workflow, not an afterthought

Desirable

• We are hiring a Senior Software Engineer to join our OLAP Platform team in Dublin
• OLAP is the analytical data layer that powers real-time reporting, search and agentic data access for AI-driven products across Toast
• We ingest events from across the business, index them into OpenSearch, and expose them to consumer teams through a federated GraphQL layer
• One platform, many tenants, restaurant-critical latency and freshness
• The team is in a pivotal stretch of work: scaling the platform to support more domains and more consumers, keeping performance and cost in balance as it grows, and opening it up safely to the next wave of AI-driven products
• This is platform engineering at real scale - the systems you build here are consumed by other engineering teams and, downstream, by the tens of thousands of restaurants that run on Toast
