Technical Lead - Message Security Detection

Job title: Technical Lead - Message Security Detection

About the Role

As a Tech Lead (SWE-3) on the Message Security Detection team, you will be our technical anchor and force multiplier. You will own the architectural blueprint for distributed data pipelines (Spark/Airflow) and cloud-native infrastructure (AWS/EKS), bridging complex system design with strategic execution. You will also lead AI productivity initiatives to accelerate how our entire engineering team builds, tests, and ships software.

What You'll Do

• Architect & Scale: Design and maintain high-throughput detection systems and backend services, ensuring low latency and high reliability.

• Data Orchestration: Lead the development of robust data pipelines using Spark and Airflow to supply detection teams with high-fidelity data for ML model training and evaluation.

• Technical Leadership: Partner with Engineering Managers to define technical roadmaps, mentor junior/mid-level engineers, and drive best practices in code quality and system design.

• AI-Driven Innovation: Lead the team in adopting AI productivity initiatives, leveraging tools like Claude, OpenAI, and GitHub Copilot to accelerate the development lifecycle and automate internal workflows.

• Cross-functional Collaboration: Work closely with TPMs, Product Managers, Data Scientists, and Security Researchers to translate complex business needs into scalable technical solutions.

• Operational Excellence: Manage and optimize cloud-native infrastructure on AWS/EKS, ensuring systems are cost-effective, secure, and performant.

• What We're Looking For

• 8+ years of professional experience: Proven track record in production-level backend development with Python or Golang.

• Data Engineering Expertise: Expert-level proficiency in building and optimizing distributed data pipelines using Spark and Airflow (or equivalent orchestration tools).

• Cloud & Infrastructure: Extensive experience managing and scaling cloud-native applications on AWS (highly preferred), GCP, or Azure, with a proven track record of hands-on container orchestration using EKS.

• Leadership & Mentorship: Experience leading technical projects, mentoring engineers, and contributing to the long-term technical strategy of a team.

• System Design: Strong ability to design complex integrations and handle significant throughput/latency challenges.

• Problem Solving: A methodical approach.
