About the role
Security Engineer role at Lambda focusing on building detections, hardening infrastructure, reviewing designs, automating toil, and incident response within a hybrid, multi-office environment.
Responsibilities
- Build and Tune Detections: Develop and refine detection content across our SIEM and EDR to catch threats targeting customer data, model weights, and infrastructure.
- Respond to Incidents: Participate in on-call, lead investigations end-to-end, and turn each incident into automation, playbooks, or controls that prevent the next one.
- Harden Systems Directly: Remediate vulnerabilities and security findings in production, partnering with engineering teams when fixes cross team boundaries.
- Review Architectures and Code: Provide actionable security feedback on high-level designs and individual changes, and turn recurring review patterns into reusable standards.
- Build Security Tooling: Ship Python or Go services that automate evidence collection, vulnerability triage, and other toil, using Lambda's hosted LLMs where they meaningfully accelerate the work.
- Partner Across Engineering: Work with Product Engineering, Data Center Operations and Engineering, IT, and Legal to land security improvements at the moments they're cheapest to adopt.
- Balance Strategic and Tactical: Recognize when to invest in a long-term fix versus when
Qualifications
- 5+ years of demonstrated security engineering experience, either directly as a security engineer or as an engineer driving security outcomes. We also welcome equivalent backgrounds: significant formal security training paired with strong engineering experience.
- A track record of working across security domains; for example, shipping detection work in one role and architecture, platform, or vulnerability management work in another.
- Thrives in high-speed, high-ambiguity startup environments where priorities shift regularly and structure must be built while executing.
- Strong hands-on Linux experience that showcases your ability to protect both our applications and the cloud we build underneath them.
- Comfortable solving problems in Python, Go, or a similar language, with the discipline to ship production-grade tooling rather than only one-off scripts.
- Excellent collaboration with technical teams both with and without authority
