Technical Lead - Message Security Detection

Abnormal Security — Hybrid - Bangalore, India

The Mission We are building the high-throughput, low-latency infrastructure that powers our real-time threat detection capabilities. This isn't just about maintaining stable backend systems; it’s about architecting a cutting-edge data platform at massive scale to turn raw data into high-fidelity, actionable intelligence for our ML models and security researchers. As a Tech Lead (SWE-3) on this team, you will be our technical anchor and force multiplier. You will own the architectural blueprint for our distributed data pipelines (Spark/Airflow) and cloud-native infrastructure (AWS/EKS), bridging the gap between complex system design and strategic execution. Beyond traditional engineering, you will lead by example spearheading our AI productivity initiatives to supercharge how our entire engineering team builds, tests, and ships software. If you are passionate about deep technical ownership, mentoring the next generation of engineers, and defining the future of our data ecosystem, this is your mission. What You Will 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
