At Anthropic, we believe new AI capabilities are best achieved through secure foundations, not in spite of them. As capabilities grow more advanced, it is critical that progress moves forward safely and for the benefit of all society. It is the reason why security sits at the center of our work, and not as an afterthought.

We're looking for a systems-oriented Software Engineer to push the performance and reliability of Claude Code and the JavaScript runtime that powers it. Claude Code is our terminal-first, agentic coding tool, and a huge part of what makes it fast—and what lets us ship quickly—is Bun. This role sits at that intersection: you'll work deep in the runtime, the kernel interfaces it sits on top of, and the agent loop on top of it, making everything faster, leaner, and more reliable. Your work will also flow through to the Claude Code Agent SDK, Cowork, and other Labs projects that build on the same foundations.

This is low-level work. We're looking for someone who has spent years writing production C, C++ and Rust, who thinks in syscalls and allocators, and who gets excited about shaving microseconds and megabytes off hot paths.

Responsibilities

• Design, build, and optimize core systems inside Bun and Claude Code—runtime internals, I/O paths, memory management, and the agent execution loop

• Drive down memory usage, latency, and startup time across Claude Code and the Bun runtime

• Dig into performance problems across the stack: profiling, tracing, and fixing issues anywhere from the kernel interface up through the JS engine to the agent layer

• Collaborate with researchers and product engineers to make sure model capabilities translate into a fast, reliable developer experience

• Contribute to the Bun runtime and toolkit, which underpins Claude Code, the Agent SDK, Cowork, and other internal Labs products

• Stay ahead of advancements in runtimes, compilers, and AI-assisted tooling—experimenting, measuring, and bringing the best ideas into our stack

You may be a good fit if you

• Have a strong background in C and/or C++ and Rust (Zig also welcome)

• Have deep systems programming experience: syscalls, Linux internals, I/O (kqueue, epoll, io_uring), manual memory management, and performance engineering

• Have worked on language runtimes, virtual machines, compilers, or JS engines like JavaScriptCore or SpiderMonkey

• Have 5+ years of work experience

Candidates must be located in the eastern time zone.

About the Role

We're looking for a software engineer to join our Source Control and Governance team within our Developer Experience group. In this role, you'll design and build the tooling and automation that keeps our AI compute and bare metal infrastructure platform compliant, secure, and audit-ready.

You'll work across major compliance frameworks (SOC 2, SOX, ISO 27001), writing policy-as-code, building compliance pipelines, integrating security scanning into CI/CD, and automating evidence collection workflows. This is a collaborative, high-impact team where your engineering work directly supports our ability to serve enterprise customers and meet evolving regulatory requirements.

What You'll Do

• Design and build automated compliance pipelines that enforce policies on infrastructure changes and compute provisioning, bringing a CI/CD-driven approach to governance workflows.
• Implement policy-as-code using tools like OPA/Rego, Conftest, or InSpec — ensuring compliance rules are version-controlled, peer-reviewed, and enforced automatically across environments.
• Automate audit evidence collection for SOC 2, SOX, and ISO 27001, replacing manual processes with continuous pipelines that produce timestamped, immutable artifacts.
• Build and maintain compliance dashboards and reporting to surface posture scores and framework coverage for internal stakeholders and customers.

What We're Looking For

• 7+ years of software engineering experience.
• Demonstrated mastery of Go or Python, including concurrency primitives, memory management, and performance optimization at scale
• Experience designing and building CI/CD pipelines using tools like GitHub Actions, GitLab CI, Jenkins, or Buildkite, with a solid understanding of pipeline architecture and design patterns.
• Familiarity with Linux systems and networking fundamentals.
• A self-directed working style with the ability to take ownership of workstreams on a small, collaborative team.

Nice to Have

• Experience with policy-as-code tools (OPA/Rego, Sentinel, Checkov, InSpec).
• Familiarity with compliance frameworks such as SOC 2, SOX, ISO 27001, or NIST CSF — you don't need to be an auditor, but an understanding of controls and why they matter goes a long way.
• Background in cloud infrastructure, bare metal, or compute platform environments.

Why This Role

As an AI compute provider, we operate in a space where the regulatory landscape is actively evolving. That means the work here goes beyond maintaining a static set of controls — you'll be building the systems that define how AI infrastructure compliance works in practice. You'll ship tooling that has a direct line to enterprise customer trust, and you'll help solve problems that don't have established playbooks yet.

This is a small team with a high degree of autonomy, meaningful greenfield projects, and real opportunity to grow as the space grows around you.

The base salary range for this role is $165,000 to $242,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location. We strive for both market alignment and internal equity when determining compensation. In addition to base salary, our total rewards package includes a discretionary bonus, equity awards, and a comprehensive benefits program (all based on eligibility).
