About Adapt

Every company will have a central company agent. Adapt is the platform for building, running, and governing it. We connect the models a company chooses to its systems, data, people, and workflows. With persistent memory, secure compute, deep integrations, reusable skills, and enterprise controls, Adapt helps the agent understand real context, complete real work, and improve over time.

Every company will have a central company agent. Adapt is the platform for building, running, and governing it. We connect the models a company chooses to its systems, data, people, and workflows. With persistent memory, secure compute, deep integrations, reusable skills, and enterprise controls, Adapt helps the agent understand real context, complete real work, and improve over time.

We believe this infrastructure should be open, portable, secure, and controlled by the organizations that depend on it. Models will change. What a company builds with Adapt stays theirs. Join us in building the platform that will define how companies work with AI.

We're hiring an engineer to own the computer underneath Adapt. This is infrastructure in service of the product, not infrastructure for its own sake. We are hiring for a systems expert, but all engineers at Adapt are expected to be in service ultimately of the product we’re building and the customers that use it. That means that your focus will always be on world‑class systems that power customer workloads.

This role's center of gravity is the layer underneath, but it is not a platform team walled off from the product. You'll sit in customer conversations, ship user‑facing features, and follow your work all the way out to the people using it.

• Sandbox:
  Firecracker-based microVM orchestration with sub-second boots for agents.
• Storage:
  Distributed file system backed by object storage, allowing concurrent read/write from multiple sandboxes.
• Infra:
  Google Cloud Platform, GKE, Kustomize, Git Hub Actions, Postgres, Redis, and the tracing and metrics for all of it.

Today that stack serves tens of thousands of sandbox sessions a week, enabling LLMs to take on and complete complex tasks for users. But this is just the beginning. We want someone who can sharpen the architecture that got us here and make the calls that take us further.

• 4-7+ years of professional engineering experience, with a meaningful chunk of it on infrastructure
• Experience working at an early stage (seed, Series A, Series B) startup, ideally one where the infrastructure was the product. A build platform, CI system, hosting provider, orchestrator, or database
• You've owned a multi‑tenant compute or build system where users ran arbitrary code on your machines and you were accountable for isolation, reliability, and cost
• You're the person teammates bring an architecture decision to before they commit to it, and you've mentored engineers without holding a manager title
• Strong in at least one systems language (e.g. Rust or Go). We use Rust for performance‑oriented services, and Typescript to glue them together.
• Comfortable at the Linux layer: cgroups, name spaces, file systems, networking. You've read kernel documentation on purpose
• Experience with one major cloud provider (we're on GCP) and Kubernetes as a tool you use directly, not one you hand to a platform team
• Deep familiarity with container and microVM runtimes like gvisor and Firecracker.
• Working fluency in full‑stack Type Script, or the appetite to get there quickly. You will ship in the product too
• Strong interest in many of the latest and greatest AI tools, models, and infrastructure market evolution
• You've carried a pager (maybe not literally) for something people depended on, and the system got better because you did
• Ability to break down a complex and large problem into independently shippable solutions (you may have found yourself saying "What's the simplest thing we can do to try to solve this problem?")
• Care deeply about users: infra work here is judged by how great a customer’s experience is with the product.
• A genuine desire to grow the craft of engineering and product‑building (you could call it…
