Benefits

Qualifications

• building consensus, and advocating for the approach that's right for engineers across Ant***
• MINIMUM
• Significant professional software engineering experience in backend or developer infrastructure domains
• Proficiency in Python
• Hands-on experience with containers (Docker or equivalent), Kubernetes, and pod-level operations
• Prior ownership of a developer environment, build system, or paved-path workflow used by a multi-team engineering organization, with demonstrable adoption
• Experience working across team boundaries to deliver infrastructure that other engineers depend on
• Daily, hands-on use of AI coding assistants as part of your own development workflow
• PREFERRED
• 7+ years of backend or developer infrastructure engineering experience
• Experience with Rust or Go
• A track record of reducing cold-start or boot time on a complex multi-service stack to under a minute, with before/after measurements

Responsibilities

• You'll also help shape how our repository and platform topology evolves as the company scales, partnering closely with the infrastructure teams who own the substrate you build on.
• Own the local and hosted development environment end to end — container lifecycle, dependency provisioning, hot reload, and the single command an engineer runs to start working
• Drive down cold-start time for fresh development environments and keep it low as the codebase grows
• Design and implement the environment isolation model (sandboxes, ephemeral environments, namespace separation) that lets engineers experiment freely without risk to shared systems
• Build and maintain the pre-push validation surface so failures are caught on the engineer's machine, not in CI
• Partner with platform, delivery infrastructure, and tooling teams to shape the repository and service topology that best supports a fast inner loop
