Platform Engineer

We're looking for a Platform Engineer to own the foundational primitives and surfaces that power Antimetal's product engineering velocity, service infrastructure, and the connectivity layer between our agents and customer environments.

This role is core to how we ship. You'll architect and operate the systems that every agent invocation, every customer onboarding, and every code review depends on - our internal admin tooling, our deploy and observability pipelines, our MCP gateway, and the integration substrate that determines whether a new customer gets value in days versus weeks. You'll partner closely with product, FDE, and research, and your work will compound across every team that builds on top of you.

About Antimetal

Antimetal is building the future of infrastructure management. We're starting by creating a platform that investigates, resolves, and prevents issues—giving engineers their time back to focus on what they do best: building great products.

What You’ll Do:

You'll work across a couple tightly coupled areas. We're flexible on entry points and will match scope to strengths.

Platform Acceleration. Maximize the productivity of every engineer at Antimetal. You'll architect and optimize the development infrastructure behind our agent and product work — internal admin tooling (Anvil), CI/CD, deploy pipelines, dev/demo environments, and the Claude-Code-native skills our engineers use every day to ship. Your work has a multiplier effect across the entire engineering org: when the inner loop is faster, every product team ships faster.

Service Infra. Build and maintain the core infrastructure that powers Antimetal's services — service architecture on Kubernetes, deployment pipelines, observability (OTEL, Datadog), shared libraries, secret management, and the platform abstractions that let product teams ship reliable services without thinking about the substrate. You'll set the bar for what "production-ready" means at Antimetal.

Data Infrastructure. Data is the substrate everything else at Antimetal runs on top of — evaluations, intelligence, experimentation, the product experience itself. If the data is wrong, thin, or disorganized, every layer above compounds the failure. You'll own the schema, storage, and access patterns for the systems we depend on most: investigation traces, agent trajectories, the resource graph, customer telemetry, and the typed blobs that capture state we don't yet know how to structure. You'll hold the line that data integrity is non-negotiable, know when to normalize and when to defer structure, and reach for the simplest primitive that will carry us the longest before adding heavier tooling.
