## About the role

We’re looking for a senior software engineer to work on the systems that launch, run, and retire sandbox environments for agent-driven software changes. You’ll own infrastructure work from design to production operation, and work closely with the product and engineering team to make each session fast to start, useful to collaborate in, and safe to review. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- You’ve built and operated production infrastructure for developer tools, cloud applications, CI systems, or other products that run user or agent workloads
- You have hands-on experience with ephemeral sandboxes or remote execution. Experience with E2B, Blaxel, or a comparable platform is especially relevant
- You understand isolation and its tradeoffs, including containers or VMs, access to secrets, networking, tenancy, and what can fail when untrusted code runs
- You can build the application-side systems around infrastructure, such as APIs, job orchestration, state management, and integrations with code repositories
- You can diagnose production incidents using logs, metrics, and traces, and turn what you learn into simpler, more reliable systems
- You write clear technical plans, make pragmatic tradeoffs, and take responsibility for the behavior of a system after it ships
