As a Lead Engineer, you will:

• Design, develop and maintain an established SIEM platform spanning 1 frontend application and 7 backend services by deploying durable interfaces using modern patterns including React & Type Script.
• Mentor junior and senior engineers through design reviews, hands on pair programming, and collaborative problem solving.
• Own and evolve the technical architecture of the SIEM platform across both the established full-stack application AND the in-flight integrations and feature sets built to support Google Sec Ops.
• Operate with a high degree of autonomy, consistently delivering outcomes with minimal oversight.
• Use technical decision authority as you partner with cross-functional teams to design, build, and deliver new or migrated security detection features and tools on Google Sec Ops, leading design reviews and resolving ambiguity from conflicting requirements through the process.
• Develop and support full-stack application features, including backend APIs (e.g., Node.js/Express), integrations with Google Sec Ops, and services that power detection and investigation workflows.
• Drive alignment both upstream and downstream as you partner with Threat Detection & Operations, Cyber Threat Intelligence, CSIRT, and platform engineering teams to design and improve detection and investigation capabilities.
• Own reliability, scalability and performance targets as you troubleshoot and resolve issues across existing systems while participating in on-call rotations and contributing to improvements in observability, resilience, and operational tooling.
• Develop and maintain state management, data-fetching, and asynchronous workflows (e.g., background processing, job scheduling) to support complex user interactions and long-running operations.
• Write high-quality, maintainable code and participate in code reviews and testing practices to uphold engineering standards and facilitate knowledge-share.
• Contribute to CI/CD pipelines and mechanisms (e.g., Docker Swarm), supporting reliable and repeatable releases.
• Use telemetry, user feedback, and platform metrics to improve application performance, usability, and reliability.

In this role, you are a hands-on technical contributor responsible for designing, building, and operating critical SIEM application experiences that power security investigations, IOC workflows, and detection authoring le remaining a deeply hands-on engineer, you are accountable for the technical direction, system health, and overall effectiveness of the SIEM Platform, including its integrations with Sec Ops and the engineers contributing to its success.

You work across the full stack writing clean, scalable, and maintainable code while optimizing for performance and reliability.

Core responsibilities of this job are described within this job description. Job duties may change at any time due to business needs.

About you:

• 4-year degree in Computer Science (or related field) or equivalent practical experience.
• 8+ years of overall software engineering experience, with a focus on building full-stack web applications.
• 3+ years of experience building modern frontend applications with React or NextJS using Type Script, including state management, form validation, and component library (e.g., MUI).
• 3+ year of experience building backend services using Node.js and Express, including API design, Express Middleware, ORMs (e.g., Sequelize), and job scheduler framework (e.g., Bull or Temporal)
• 3+ years of experience with relational databases (e.g., MySQL, PostgreSQL).
• Demonstrated ability to define and evolve system architecture to bring cross-team initiatives from concept to production.
• Experience working in large, multi-repository codebases and applying testing practices (e.g., Jest, Vitest or similar).
• Experience with containerized applications and modern CI/CD pipelines (e.g., Docker, Docker Swarm, or similar).
• Working knowledge of observability practices (logging, metrics, tracing, APM)
• Ability to troubleshoot and debug issues across the stack in production environments, identifying root causes and implementing solutions.
• Experience supporting applications in production, including monitoring, incident response, and on-call participation.
• Demonstrated code quality practices, including writing maintainable code and participating in pull request reviews.
