About the company
Toast creates technology to help restaurants and local businesses succeed in a digital world.
Responsibilities
- Spend the majority of your time "hands-on-keyboard," architecting, coding, and operating high-performance backend services using Kotlin and AWS.
- Take working agentic prototypes built by Finance operators and turn them into scalable, monitored, and permissioned microservices with audit trails and automated error handling.
- Build pragmatic, full-stack operator tools—from backend APIs and pipelines down to the lightweight UI surfaces used daily by collections analysts and revenue accountants.
- Design resilient integrations across billing platforms, ERP systems, Salesforce, data warehouses, and internal Toast services using enterprise integration patterns.
- Proactively engineer around SOX scope, PCI boundaries, and data access requirements alongside Security, Compliance, and Audit teams.
- Own end-to-end technical strategy from high-level business problems down to build sequencing.
Requirements
- Proven track record as a Staff (or senior-level lead) engineer with deep expertise in distributed backend systems, paired with the practical ability to ship frontend UI surfaces or admin portals.
- Advanced hands-on experience shipping Kotlin (or strong JVM equivalent) services on AWS.
- Practical experience productionizing LLM frameworks and agentic architectures (tool use, retrieval/RAG, evals, context management).
- Extensive experience with enterprise integration frameworks, message brokers, and distributed data stores—specifically Apache Camel, Apache Pulsar, DynamoDB, and Dropwizard (or direct equivalents).
- Advanced data engineering instincts across SQL, warehouse modeling, pipeline design, and managing data flow/consistency across relational and NoSQL storage systems.
- Ability to balance immediate high-impact automation with long-term platform scalability, accompanied by exceptional technical writing.
Conditions
- The base salary range for this role is $193,000 - $309,000 USD per year (Zone A).
