Lead Engineer – Cyber Visibility UI Development

About the role

The Lead Engineer – Cyber Visibility UI Development at Target is responsible for designing, developing, and maintaining an established SIEM platform. This includes deploying durable interfaces using modern patterns like React & TypeScript, mentoring junior and senior engineers, owning and evolving the technical architecture, and driving alignment with cross-functional teams.

Responsibilities

• 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 & TypeScript.
• 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 SecOps.
• 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 SecOps, 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 SecOps, 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.

Requirements

• 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 TypeScript, including state management, form validation, and component library (e.g., MUI).
• 3+ years 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.
