Software Engineer, Infrastructure

About The Position

Platform owns the foundation the company runs on: compute and deployment, reliability and on-call, CI/CD and monorepo health, developer environments, the infrastructure that model training and inference run on, and the security boundaries around all of it. AI and agent tooling is the clearest example. You will contribute to how models are trained and served here, as well as how agents work inside our codebase: the environments they run in, the verification that makes their output trustworthy, and the review paths that keep it all legible. There is no industry standard and you’ll help form our opinions rather than inheriting one. Our users are other engineers. Expect to spend time with all the other engineering teams, understanding their needs and building a roadmap. The scope is large, so you'll be choosing what to leave alone as much as build. Architecture decisions here last: this is a small team covering a large surface. You'll have real room to decide things, and you'll stay close to the systems you decide about.

Requirements

8+ years building and operating production distributed systems, or equivalent server-side engineering with a heavy infrastructure focus.
Effectively leverage agents to multiply your impact and think critically about how and when to harness AI in your work.
Experience running systems where failure was expensive, and your opinions about reliability and deployment come from consequences rather than reading.
Experience carrying a pager, commanding an incident, and rolling back before you understood why.
Experience using SLOs and error budgets as operating tools.
Experience using a major cloud provider and Kubernetes in production, with infrastructure-as-code as your default.
Experience owning an architecture or migration, from planning through launch, whose consequences outlived the project, and you can say what you'd do differently.
Experience finding important unowned work, scoping it, earning buy-in, and delivering it without being handed a spec.
Ability to build a minimal repro, read the logs, and write targeted checks to prove a fix works instead of trusting output.

Nice To Haves

GPU and ML infrastructure: capacity planning, training or inference pipelines, serving cost and latency. If you haven't run a GPU fleet, experience with expensive capacity-constrained systems transfers well.
Production security engineering: IAM, secrets, supply chain, least privilege. You don't need to have held a security title, but you should have owned these boundaries for systems you ran.
Cloud cost modeling: commitment strategy, reservations, unit economics.
CI/CD: at monorepo scale, and developer-environment work.
Intricacies of Video: Media, video, or GPU-backed workloads.
Small teams owning a large surface: whether at a Series B to D company or on an internal platform team.

Responsibilities

Own our platform: GCP, Kubernetes, Temporal, the GPU fleet behind cloud export, and the deploy and rollback machinery everything ships through. You'll be in the on-call rotation, and we'll expect you to make it quieter and more actionable.
Own the AI enablement substrate: GPU capacity, training and inference pipelines, and the reliability and cost of the systems serving models in production.
Manage cost as an engineering constraint: make smart trade-offs for infrastructure decisions that have a number attached. As inference grows with usage, the metering and attribution behind those numbers sit with this team.
Ensure security comes with the systems you run: identity and access, secrets management, least-privilege boundaries, and supply-chain integrity.
Make what you build legible: Infrastructure-as-code that explains itself. Runbooks and in-repo context written for someone jumping in to help. Observability that tells you what failed and why.
Improve how the team learns and ships: Form hypotheses, instrument your work, release incrementally, and read results honestly. Strengthen the tooling, standards, tests, observability, and release practices that help the team move quickly without compromising quality.
Raise the team’s technical ambition: Provide architectural direction, thoughtful reviews, mentoring, and clear human writing.
