Senior Security Engineer

Curri is hiring its first dedicated Senior Security Engineer to build and own security across its applications, cloud infrastructure, and AI engineering platform. The role focuses on developing security tooling and guardrails, leading detection and incident response, managing vulnerabilities and compliance, and helping engineers ship securely.

Responsibilities:

• Own application and cloud security end to end: threat modeling, secure design reviews, and hands-on work on sensitive code paths across our TypeScript/Node GraphQL API, React and React Native apps, Go services, and AWS/EKS infrastructure defined in Pulumi
• Build internal security tooling and guardrails instead of gates, such as authentication services, access proxies, secrets handling, policy-as-code, and CI checks that developers barely notice until they save them
• Secure our AI-forward engineering platform. Curri runs autonomous agents that review, write, and deploy code; you'll own their access boundaries, credential handling, prompt-injection defenses, and audit trail, along with the policies for how staff use AI tools
• Turn our security scanning (SAST, secrets, container, and IaC) into a program with signal: tune it, triage it, and drive findings to closure against clear SLAs
• Stand up detection and response: build high-signal alerting across cloud, identity, and application logs, lead security incidents, and make sure postmortem follow-through actually happens
• Run the vulnerability lifecycle: scope and manage external penetration tests, validate and prioritize findings, partner with teams on fixes, and verify closure
• Partner on compliance and customer trust: help run our SOC 2 program, answer enterprise security reviews, and turn what customers ask for into program improvements, not just questionnaire answers
• Raise the security bar of the whole engineering team by mentoring engineers on secure design patterns, especially authorization, identity, and multi-tenant data isolation, and making security a normal part of how we ship
• Communicate risk clearly to engineers, executives, and customers in the terms that matter to each, and help shape the security roadmap as the function grows

Requirements:

• 8+ years of professional experience in software engineering and/or security, including at least 3 years focused on application, product, or cloud security
• A track record of designing and building secure web applications, APIs, and internal tools. You read and write production code and are credible in a code review
• Deep, hands-on knowledge of web and API vulnerabilities, especially authorization flaws (IDOR/BOLA), authentication and SSO (SAML, OIDC, JWT), SSRF, and injection, and how to find and fix them at scale
• Strong cloud security experience in AWS and Kubernetes: IAM, network segmentation, workload isolation, secrets management, and infrastructure as code
• Experience leading security incidents, ideally as the person in charge, with calm, diligent response and clear communication
• The ability to work as a team of one: you prioritize by real risk, make pragmatic tradeoffs, and ship without a playbook handed to you
• Fluency with AI-paired delivery (Claude Code, Cursor, or equivalent), and a clear view of the new risks AI agents and LLM-integrated apps introduce
• Strong, direct communication with technical and non-technical stakeholders, and empathy for the developers and customers you're protecting
• Being an early or first security hire at a startup, and being able to speak to what you built first and why
• Detection engineering experience implementing and maintaining a SIEM or detection-as-code pipeline
• Securing LLM applications or agentic systems, including familiarity with the OWASP LLM/Agentic Top 10, MCP, or AI governance frameworks like NIST AI RMF
• Experience with SOC 2, ISO 27001, or enterprise customer security reviews
• Proven offensive skills, such as pentesting, bug bounty, or CTFs, used to assess real-world exploitability
• Experience with our stack: TypeScript, Node, GraphQL, Postgres, Go, EKS, Pulumi, NATS
• Contributions to the security community through research, talks, open source, or writing
