# Software Engineer, Core Infrastructure

- **Company:** The Nook
- **Location:** San Francisco, CA, United States
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Application Programming Interfaces (APIs), Databases, Continuous Integration, Programming Tools, Distributed Systems, Data Access Layer, Data Layers
- **Published:** September 4, 2026
- **Apply:** https://startup.jobs/senior-software-engineer-core-infrastructure-nooks-8024388

## About the Role

* 5+ years of engineering experience, with depth in distributed systems, databases, or developer infrastructure. We don't care which exact stack.
 * Production experience scaling systems through real growth (10x, 100x), and the scars that come with it.
 * Strong opinions, held loosely, about what good developer experience looks like inside a fast-moving product team.
 * Comfortable being the engineer everyone else calls during an incident.
 * You make the rest of the team faster.
 * Based in San Francisco, excited to be in-office 3+ days per week.

## Description

The Core Infrastructure team makes the rest of Nooks fast. We're going from one product to many - Sequencing, Dialer, Agent Studio, Coaching - and our data layer, observability, and developer tooling have to scale with that. The dialer alone runs ~100M calls a week, and reps spend 4+ hours a day in the product. We're hiring senior engineers to own the systems everything else is built on., * Build infrastructure that makes every product team faster. Data models, APIs, observability, CI/CD - pick the area, own it across the company.

 * Keep the rails on while we go multi-product. Capacity, reliability, cost. Set the standards other teams build against.
 * Make foundational technical decisions. What's the right shape for our data access layer when we're querying across calls, prospects, and accounts? How do we attribute infra cost to product teams cleanly?
 * Mentor others on the team. Run code and design reviews, and pair on the hardest problems.
