Full Job Description
The Role

You'll own the internal developer platform that every engineer at Monaco builds on - the systems, environments, and tooling that turn an idea into shipped product with as little friction as possible. This is a high-leverage, wear-many-hats role: your work multiplies the output of the entire engineering team. You'll define the golden paths for how we develop, test, and ship, and you'll get to do it at a company that treats AI-assisted development as a first-class part of the workflow, not an afterthought.

What You'll Do
  • Build out Monaco's internal developer platform. Create the self-service tooling, golden paths, and internal systems engineers reach for every day - and set the standard for what great developer experience looks like here.
  • Extend functionality to development environments. Bring new capabilities to both local and cloud-hosted dev environments so engineers get a fast, production-like setup wherever they work.
  • Own our remote development environment orchestration. Take ownership of the internal system that provisions and manages cloud-hosted development environments at scale.
  • Own our internal AI-assisted engineering automation. Take ownership of the platform that brings AI agents into our engineering workflows, extending what the team can automate and accomplish.
  • Own test data propagation to lower environments. Make realistic, safe data flow into development and QA systems so engineers can build and test against environments that mirror production.
  • Partner across engineering. Work directly with product teams to find and remove friction across the full development lifecycle, and grow the platform as the company scales.
What We're Looking For
  • 5 + years of experience building internal developer platforms or developer-experience tooling that other engineers depend on.
  • Deep hands-on experience with AWS, Kubernetes, Terraform, and GitOps-based delivery (e.g. FluxCD, Helm).
  • Experience provisioning and managing developer environments - local and cloud-hosted.
  • Comfort building self-service systems and internal tools that make the right thing the easy thing.
  • Ability to ramp quickly and move fast without hand-holding.
Nice to Have
  • Experience with test data seeding, cloning, or anonymization for lower environments.
  • Experience integrating AI/LLM tooling into developer workflows.
  • Container and machine-image build experience (Docker, Packer) for reproducible environments.
Location

San Francisco. We're an in-person team - 5 days in the office. At this stage, proximity genuinely accelerates product quality and team cohesion.
