Senior Backend Engineer
About the Role
Build and operate the backend systems that help AI agents reliably carry out work through connected tools. You will own core infrastructure across integrations, secure execution environments, and multi-tenant data, with a direct impact on product reliability and customer outcomes.
What You'll Do
Design and operate a tool gateway that exposes connected APIs and MCPs through a composable Python SDK, including routing, authentication, rate limits, and reliability.
Run persistent, isolated Linux sandboxes for workspaces, with attention to security, autoscaling, and cost.
Build and maintain durable, high-performance data systems for multi-tenant workspace state and persistence.
Find and resolve integration failures, then improve system design to prevent them from recurring.
Work closely with company leadership and users to make technical decisions and deliver improvements quickly.
What We're Looking For
3 to 10+ years of experience building and operating production backend systems.
Strong experience with distributed systems, production reliability, and designing for failure at scale.
