Senior Software Engineer, Infrastructure

As a Senior Infrastructure Engineer, you're a senior voice on Engine's central infrastructure team — the group that owns the substrate every product team at Engine ships on top of. Your work is horizontal by default: the patterns you design, the modules you ship, and the paved roads you maintain are used across every business vertical.

You'll be hands-on with:

• Cloud infrastructure — the AWS accounts, networking, deployment patterns, and operational tooling that Engine's product teams depend on day to day.
• Terraform — designing and evolving the shared module registry that feature teams across the company consume.
• CI/CD — pipeline templates and GitHub Actions workflows that set the standard for how code ships at Engine.
• Reliability & observability — Datadog dashboards, SLO frameworks, and incident response tooling used org-wide.
• Security & networking — Cloudflare configuration, IAM boundaries, and secret management as platform-level primitives.
• Cost visibility — building the tooling and reporting that helps every team understand and act on what they own and spend.

You'll partner closely with feature teams across verticals — not by embedding with them, but by running a tight feedback loop: understanding their friction, prioritizing what deserves a paved road, and shipping platform capabilities that make the right path the easy path.

What You'll Do

• Set the technical direction for a major area of Engine's infrastructure over a multi-quarter horizon — where it's headed, what you're deliberately not building, and how platform investments compound rather than fragment.
• Lead multiple infra initiatives in parallel, coordinating across the central team and with the feature teams who'll adopt what you build.
• Design and ship the Terraform modules, pipeline patterns, and operational tooling that product teams adopt because they're better than the alternative — not because they're mandated.
• Separate signal from noise across the feature-team requests that land on the central team. Decide what deserves a paved road, what belongs in team-owned space, and what shouldn't be built at all.
• Own the boring-but-critical work: incident response, on-call quality, deployment reliability, vendor integration health.
• Shape the guidelines, tools, and methods every engineer at Engine uses — and coach the feature engineers who apply them.
• Represent the infra team in cross-functional conversations with product and engineering leadership. Our team meets twice a week — that's where you'll share what's shipping, align on priorities, and pressure-test decisions.
• Reduce the SDLC step-function count across Engine. Every approval gate, every "ask infra first" workflow is a tax — your job is to lower it.

What We're Looking For

Required

• 6+ years building and operating production cloud infrastructure, with deep AWS expertise (multi-account, networking, IAM, security boundaries).
• Expert-level Terraform — you've designed reusable modules and have opinions about state, drift, and execution patterns.
• Strong CI/CD background — GitHub Actions, reusable workflows, OIDC, secret management.
• A track record of shipping platform infrastructure that feature teams actually adopt — you know how to build for internal customers without losing sight of what makes something feel like a product.
• A bias toward enabling teams over gatekeeping. You'd rather build the paved road than approve the off-road permits.
• Experience leading technical direction across multiple teams — making the trade-offs precisely, communicating them clearly, and bringing other engineers along.
• Instinct for when a problem deserves a central solution and when it should stay with the team that hit it.

Strongly preferred

• Cloudflare (WAF, DNS, zero-trust/WARP) at production scale.
• Datadog, JFrog, or comparable vendor integration experience.
• Background in cost observability or FinOps tooling.
• History of working on a platform team that serves internal customers — you understand the difference between running a platform and running a gate.

Applications for this role will be accepted through 11/1/2026 or until the role is filled. We encourage you to apply early, as we may begin reviewing applications before the deadline.
