Software Engineer, Developer Infrastructure

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.

• Are technically deep in infrastructure — AWS, containers/ECS, networking, IaC — and pragmatic about it.

• Have a product builder’s instinct for developer experience: sane defaults, tooling that teaches, “shipping means seeing it work successfully.”

• Like discovering the problem by meeting your users: pairing with engineers, watching onboarding, reading the friction in Slack.

• Are comfortable building in-house when it’s the right call (and explicit about when a third-party tool earns its place).

• 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).

• 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).

As an engineer at Numeric you will learn the domain, meet your users, and exercise substantial creativity and agency over product direction. You'll work with a high-pace, high-integrity team that loves collaboration.

We believe the best company is the one with the best ICs and we’ve built a culture to maximize great work. We believe great product & engineering come from a desire to win, a deep care for the craft, and a pragmatism in shipping for overall impact. As engineers we ground our work in our understanding of the users, the domain, and the goals for our organization.

We strongly believe we will only be successful if everyone on the team is anchored in our following set of core principles:

• Own the Outcome: We own our results. We typically hire builders and give them large mandates with high-trust. Engineers are responsible not just for code, but for ensuring the product is solving the end problems of the users.

• Brick by Brick: To win, our team needs to show up and execute in each domain every day.

• Love the Game: We focus on the craft and a deep sense of giving a f*ck. We’re building a company full of people who are equally engaged and motivated.

• Earn the right: Our ability to rethink how things are done depends on the trust and reputation we build by shipping quality products and improving the lives of our users.

• SALY: We refuse to accept “Same As Last Year.” We bring fresh eyes to a stagnated and underserved domain. We’re driven by a first-principles approach to building better solutions.
