AWS Rust Jobs: Firecracker, Bottlerocket, and Hiring

Max WellsMax WellsFounder of Rustify
AWS

AWS runs Rust in production at the base of its compute platform. Firecracker, the microVM manager behind Lambda and Fargate, is written in Rust, and Bottlerocket, its container operating system, is Rust-heavy. Here is the full picture and how to get hired.

AWS is both a major Rust user and a major Rust sponsor: it employs core maintainers, funds the Rust Foundation as a top-tier member, and runs Rust in the software that isolates customer workloads.

TL;DR

  • Firecracker, the virtualization technology under AWS Lambda and Fargate, is written in Rust and open source.
  • Bottlerocket, AWS's Linux-based container host OS, has a large Rust codebase for its API and update system.
  • AWS employs maintainers of Tokio and other core crates and is a founding member of the Rust Foundation.
  • Rust shows up across S3, EC2, networking, and databases teams for control-plane and data-plane components.
  • Hiring is broad and continuous, spread across many AWS service teams rather than one Rust org.

Does AWS Use Rust?

Yes, and its use is both deep and public. The clearest example is Firecracker, a virtual machine monitor AWS built to run serverless workloads with strong isolation and fast startup. Firecracker launches a lightweight microVM in around a hundred milliseconds, which is what makes per-request isolation practical for Lambda. It is written in Rust and was open-sourced in 2018. AWS chose Rust specifically because a VMM handles untrusted input at a security boundary, and a memory-safety bug there would be a serious problem.

Bottlerocket is the second major example: a minimal operating system for running containers, with its management API, settings system, and update mechanism written in Rust. Beyond these flagship projects, AWS teams use Rust across storage, networking, and database services, and AWS has publicly discussed Rust's role in reducing both bugs and energy use at data-center scale.

AWS also backs the language itself. It is a founding platinum member of the Rust Foundation, it employs several full-time open-source Rust maintainers, and it publishes an "AWS and Rust" content stream.


What AWS Builds With Rust

  • Firecracker. The microVM manager under Lambda and Fargate. Security isolation plus fast boot.
  • Bottlerocket. Container host OS. Rust for the API server, the settings and templating system, and the update client.
  • Nitro and virtualization tooling. Components around the Nitro system and related low-level tooling.
  • Storage and networking services. S3, EBS, and networking teams have adopted Rust for performance-sensitive and correctness-sensitive components.
  • Databases. Teams behind services in the Aurora and DynamoDB families have used Rust for storage and proxy layers.
  • Client tooling and SDKs. The AWS SDK for Rust and supporting code generation.

The Evidence

  • The Firecracker open-source project and its design paper, presented at NSDI 2020.
  • The Bottlerocket GitHub organization, with the OS split into many Rust crates.
  • AWS's "Sustainability with Rust" blog post and its Rust Foundation membership announcements.
  • Public talks by AWS principal engineers on why AWS picked Rust for isolation boundaries.
  • A large and steady volume of AWS job postings across service teams that list Rust as a required or strongly preferred language.

Hiring Signals

There is no single "Rust team" at AWS. Rust roles are spread across service teams: Lambda, Fargate, EC2, S3, VPC networking, and several database orgs all hire engineers to work on Rust components. Titles follow Amazon's standard ladder: Software Development Engineer II, Senior SDE, and Principal Engineer.

Typical US total compensation, which at Amazon is capped on base and heavily equity-weighted:

  • SDE II: roughly 160K to 210K USD.
  • Senior SDE: roughly 230K to 320K USD.
  • Principal: 400K USD and up.

Locations include Seattle, the Bay Area, Austin, Boston, and remote for some teams. For low-level roles on Firecracker, Bottlerocket, or Nitro, systems and virtualization experience matters as much as the language.


How to Get Hired Onto a Rust Team at AWS

  1. Target a specific team. Decide whether you want virtualization, storage, networking, or databases, and tailor your application. AWS interviews are team-matched.
  2. Show systems depth. Operating systems, memory management, concurrency, and security boundaries. Firecracker and Bottlerocket are systems projects first, Rust projects second.
  3. Contribute to an AWS open-source Rust project. Firecracker and Bottlerocket both take external contributions. Even small fixes demonstrate that you can navigate a large Rust codebase.
  4. Prepare for Amazon's interview loop. Leadership Principles behavioral questions carry real weight alongside the coding and design rounds.

Frequently Asked Questions

Is AWS Lambda written in Rust?

The isolation layer under Lambda, Firecracker, is written in Rust. The broader Lambda service is built from many components in several languages, but the piece that makes per-request isolation fast and safe is Rust.

Does Amazon outside of AWS use Rust?

Yes. Rust appears in parts of the retail business and in Alexa and devices teams, though AWS is where the public Rust story is strongest.

Do I need virtualization experience to work on Firecracker?

For core Firecracker or Nitro roles, yes, or at least strong operating-systems fundamentals. Other AWS teams using Rust for application-level services are more flexible.

Is Rust experience required for AWS SDE roles?

For roles on Rust components it is usually required or strongly preferred. Many teams will also consider a strong systems engineer who can demonstrate the ability to learn it quickly.

Why did AWS pick Rust for Firecracker?

A virtual machine monitor sits on a security boundary and parses untrusted input. Rust gives memory safety without a garbage collector, which matters for both security and the fast, predictable startup Lambda needs.
