Product Engineer (Backend)

Job summary

Responsibilities

You'll own the systems that make Granola fast, accurate and trustworthy for the next 100x of users, and you'll help decide what's worth building. Our backend engineers talk to users and ship product, not just services.

• The voice pipeline. Scale real-time transcription so notes land accurately in seconds, on every device people use.
• New models in production. Evaluate new voice and transcription models as they're released, and get the best ones into users' hands.
• The agent harness. Build the harness Granola's agents run in: long-running jobs, tool calls, retries, and retrieving the right context.
• APIs and integrations. Extend the APIs and integrations that let people bring Granola context into the AI tools they already use.
• Enterprise-grade trust. Build the permissions, data isolation and admin controls that let a company roll Granola out across every team.

What they're looking for

• You've owned backend systems in production that real users depended on, and you can talk through the trade-offs you made.
• You're strong in TypeScript and Node.js.
• You know relational databases deeply (we use Postgres): query plans, indexing, and migrations without downtime.
• You're comfortable with cloud infrastructure as code (we use AWS, Terraform and a lot of Lambda).
• You think about security and failure modes before the happy path.
