Lead Engineer – Cyber Visibility UI Development

Lead Engineer

The pay range is $132,000.00 - $238,000.00

Pay is based on several factors which vary based on position. These include labor markets and in some instances may include education, work experience and certifications.

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 at Target.

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 & 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.

This position will operate as a Hybrid/Flex for Your Day work arrangement based on Target's needs.
