Security Engineer

Investigate reported vulnerabilities at the code level, including our Rust core, Go and Python tooling.

Enable engineers to build secure systems: provide tooling, paved-road defaults, documentation, and practical guidance so security is the easy path, not a checkpoint.

Partner with engineering teams to design, review, and verify fixes, and set clear security requirements on changes where the risk warrants it.

Harden and maintain our GitHub organization’s security posture, including secret scanning, push protection, branch protection and rulesets, dependency alerts, and code scanning, in partnership with the engineering teams that use these repositories daily.

Monitor, investigate, and respond to security alerts across AWS, Kubernetes, CI/CD, and related infrastructure.

Track and report security metrics (vulnerability remediation SLAs, MTTR, patch latency, critical findings) and keep reporting current for the Security Officer.

Implement, configure, and maintain security tooling across our development and cloud environments.

Support security incident response, including investigation, containment, remediation, and follow-up.

Maintain clear, complete, and auditable records of vulnerability and incident work in our tracking systems.

Build security automation and guardrails that scale across the development lifecycle: CI/CD security checks, policy-as-code, GitHub automation, and automated cloud security controls, so secure defaults are enforced by tooling rather than review.

Participate in threat modeling and architecture reviews for new services and major changes.

We are also building out our ISMS, which creates opportunities to contribute to security-tooling evaluations, technical vendor assessments, and proof-of-concept work. Formal compliance ownership, vendor risk assessments, and customer security questionnaires remain with the Security Officer.

This is a hands-on technical role focused on security engineering, vulnerability management, and incident response. The Security Officer owns compliance, formal third-party risk assessments, and customer security questionnaires, allowing you to focus primarily on engineering work. On-call expectations are low: there is no formal rotation, though occasional availability for high-severity incidents is expected.

Who you are

You can read and navigate an unfamiliar codebase (Rust, Go, Python) well enough to validate a vulnerability report, trace its impact, and judge whether a proposed fix actually closes it.

You write and maintain automation and security tooling comfortably, and can hold a credible technical conversation in code review.

Experience triaging vulnerability reports or working with a bug bounty program, vulnerability disclosure program, product security team, or similar function.

Practical knowledge of cloud and container security, particularly AWS and Kubernetes.

Familiarity with GitHub security features and securing CI/CD pipelines.

The ability to investigate alerts and vulnerabilities methodically, distinguish genuine risk from noise, and recommend proportionate remediation.

Clear written communication skills for working with external researchers and internal engineering teams.

A self-directed approach and comfort independently managing a security queue.

3+ years in a hands-on security engineering, product security, or vulnerability management role.

Nice to have

An offensive security background, such as penetration testing, CTF participation, vulnerability research, or exploit analysis.

Experience working in an open-source company or contributing security improvements to open-source projects.

Familiarity with cloud-native incident response.
