Software Engineer, Developer Infrastructure

Numeric • San Francisco, CA

1d • $125,000 - $250,000 • Onsite

About The Position

Platform Engineering at Numeric is engineering for engineering. Our customers are our own engineers and, increasingly, the AI agents working alongside them. The mission: make every engineer and agent dramatically more productive by building a shared platform, so anyone can go from idea to safely deployed change without bespoke setup or tribal knowledge. This role is the developer-infrastructure half of that mission — environments, CI/CD and deployment, infrastructure-as-code, environment parity, observability, security, and internal tooling. The current reality has gaps (deploys with no staging gate, migrations without clean rollback, a prod-DB-clone lock that blocks deploys, Terraform drift, two clouds where there should be one) and a roadmap to close them. You’d own pieces of that roadmap end to end and then watch engineers actually use them.

Requirements

• 3+ years of software engineering experience, including significant time on 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).

Nice To Haves

• Prior experience with tools like Spacelift / Atlantis, Datadog / Firetiger / Chronosphere, or GitHub Actions / Buildkite
• Running incident-management, defining SLAs, and keeping sites up through enormous traffic
• Supporting non-engineer contributors (e.g., support engineers shipping fixes with AI tools).

Responsibilities

• Own pieces of the roadmap end to end and then watch engineers actually use them.
• 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 so reviewers can verify behavior, not just read code.
• 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), an ownership registry, and an 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 — the platform that lets anyone at Numeric ship an internal tool without re-solving auth, hosting, and observability.
