About the role

Platform Engineering role focused on developer infrastructure, environments, CI/CD, IaC, observability, security, and internal tooling to improve productivity for Numeric engineers and AI agents.

Responsibilities

  • Deployment process: serialized, gated deploys across services; automated schema migrations with rollback; staging → production promotion that engineers trust.
  • Environments & parity: local and remote dev environments that are reliable and fast to stand up; sandboxes and preview/review environments for verification.
  • Agent-First development: Including MCP gateways, governance, cost management, and foundation model selection.
  • Infrastructure-as-code: Spacelift/OpenTofu, drift remediation, consolidating off DigitalOcean onto AWS, and IaC standards that are easy to follow by default.
  • Repo standards & ownership: repository standards (linting, testing hierarchy, ownership manifests, idempotent onboarding), ownership registry, and internal developer portal.
  • Observability foundations: local tracing/logging/metrics for every engineer, Datadog cost and hygiene, incident-management maturity, status pages.
  • Security & access: unified secrets/config management, SSO in front of internal sites, IAM scoping, ECR scanning, audit logging, vulnerability management.
  • AI Internal tools hosting: Numeric Labs — platform for shipping internal tools with minimal friction around auth, hosting, and observability.

Qualifications

  • 3+ years of software engineering experience, with substantial infrastructure, platform, or developer-productivity work.
  • Confidence with AWS, IaC (Terraform/OpenTofu or similar), CI/CD systems, and Linux/container fundamentals.
  • Strong general-purpose programming skills (primarily TypeScript, Python where it fits).
