## About the role

Handshake is hiring a Senior Software Engineer to join Backend Platform, with an initial focus on supporting Handshake AI (HAI) and internal AI initiatives. You will build and maintain backend services, shared platform capabilities, and developer tooling that support HAI and internal AI initiatives. The work centers on core backend platform concerns—service architecture, APIs, data systems, performance, reliability, and developer experience—in an area making increasing use of LLMs and agents.

## What they're looking for

- 5+ years of professional software engineering experience, primarily in backend or platform engineering
- Experience designing, building, and operating production services and APIs
- Strong understanding of distributed systems, data modeling, service boundaries, common backend architecture patterns, and reliability and performance tradeoffs
- Strong experience with relational databases, including schema design, query optimization, indexing, transactions, and diagnosing database-related performance problems. Experience with PostgreSQL is especially relevant
- Familiarity with backend technologies such as Temporal, Redis, Elasticsearch, GraphQL, or event-driven systems
- Experience operating services in cloud and containerized environments. Our broader platform uses technologies including GCP, Kubernetes, Terraform, and Docker
