Job summary

Braintrust is seeking a Detection and Response engineer to design and build security systems that identify threats across the Braintrust stack. You will run detection-as-code, lead incident response, and stay ahead with real-time threat intelligence.

You will work with Python/TypeScript/Go, AWS, Kubernetes, and cloud endpoints; build telemetry pipelines; investigate incidents; write postmortems; and contribute to AI/LLM security controls.

Qualifications

• Experience designing and operating detection and response systems.
• Hands-on incident handling and postmortems.
• Experience with cloud platforms (AWS, Azure or GCP) and Kubernetes.

Responsibilities

• Build security telemetry pipelines across cloud execution environments (ECS/K8s), CI/CD systems, identity systems, endpoints, and agentic workloads.
• Continuously improve detections for attacks, abuse, and anomalous behavior.
• Own the alert pipeline end-to-end and keep signal-to-noise high.
• Lead incident response and participate in on-call: triage, scope, contain, and remediate incidents, then write postmortems that produce durable improvements.
• Hunt proactively for threats and build tooling for turning evidence into new detections.
• Build agents that triage alerts, enrich findings, gather evidence, and scope incidents with human-in-the-loop controls.
• Run vulnerability response, evaluating impact and driving remediation across our infrastructure.
• Proficient in modern backend technologies and comfortable writing real code in Python, TypeScript, or Go.
• AWS experience and working fluency in at least one of Azure or GCP.
• Kubernetes detection: audit logs, runtime telemetry, and workload identity.
• Knowledge of endpoint security (MacOS) and detection and response techniques.
• Hands-on incident experience: on call, led incidents, and written postmortems.
• Strong written and verbal communication.
• A clear point of view on AI/LLM security and hands-on experience defending relevant threats.
• Bonus: prior experience with LLM red-teaming or AI threat defense.

Job description

Braintrust is the agent observability platform. By actively applying intelligence to agent traces and automatically surfacing the most critical patterns, Braintrust gives teams the visibility to understand how agents behave in production and the tools to improve them.

Teams at Notion, Stripe, Box, OpenAI, and Cloudflare use Braintrust to trace their agents, find the issues in their observability data, and run evals that tell them how to improve.

About the role

We're looking for a Detection and Response engineer to design and build systems that identify, analyze, and eradicate threats across the Braintrust stack. You'll practice detection-as-code, run security operations with agents, lead incident response, and stay ahead of the curve incorporating real-time threat intelligence. Have a big impact with a small team that has outsized capabilities.

What you'll do

• Build security telemetry pipelines across cloud execution environments (ECS/K8s), CI/CD systems, identity systems, endpoints, and agentic workloads
• Continuously improve detections for attacks, abuse, and anomalous behavior
• Own the alert pipeline end-to-end and keep signal-to-noise high
• Lead incident response and participate in on-call: triage, scope, contain, and remediate incidents, then write postmortems that produce durable improvements
• Hunt proactively for threats and build the tooling for turning evidence into new detections
• Build agents that triage alerts, enrich findings, gather evidence, and scope incidents, with human-in-the-loop controls and evals that keep the automation trustworthy
• Run vulnerability response, evaluating impact and driving remediation across our infrastructure
• Proficient in modern backend technologies and comfortable writing real code in Python, TypeScript, or Go
• AWS experience (IAM, VPC, KMS, GuardDuty, CloudTrail) and working fluency in at least one of Azure or GCP
• Kubernetes detection experience: audit logs, runtime telemetry, and workload identity
• Knowledge of endpoint security (MacOS) and detection and response techniques
• Hands-on incident experience: you've been on call, led incidents, and written postmortems
• Strong written and verbal communication
• A clear point of view on AI/LLM security and hands-on experience defending relevant threats
• Bonus: prior experience with LLM red-teaming, agent sandbox research, or other AI-relevant security threat defense

Benefits include

• Medical, dental, and vision insurance
• Daily lunch, snacks, and beverages
• Flexible time off
• Competitive salary and equity
