Role Overview:

We need a Software Engineer with 5+ years of experience who has led the design and evolution of large-scale distributed systems in production. At CloudSEK, you will architect and drive critical backend systems that ingest, enrich, and process massive volumes of security signals in real time — systems that demand correctness, performance, and operational resilience.

As an SDE III, you will own architectural direction, influence engineering standards, and make high-impact technical decisions that shape the platform’s long-term scalability. You will work across services, guide complex backend initiatives, and mentor engineers while ensuring our systems remain reliable under unpredictable and high-volume workloads.

This role is for engineers who think beyond individual services — who design for multi-year evolution, anticipate failure modes, and build systems that other engineers depend on.
