Staff Software Engineer (Java) - Endpoint Security

responsibilities include : Design, develop, implement, test, document, and operate large‑scale, high‑volume, and low‑latency backend platform services - that turn customer intent (for example, exclusions, policies, and security controls) into effective configuration on every protected endpoint. Improve reliability, scalability, and observability of configuration management, ensuring configuration changes can be processed at scale, meet latency and throughput objectives, and be traced end‑to‑end across systems. Translate business and functional

requirements into robust, scalable, and operable configuration solutions that fit within our overall data and control‑plane architecture. Maintain application stability and data integrity by defining and monitoring key metrics and SLOs (for example, configuration delivery latency, error rates, configuration coverage) and continuously improving the codebase and architecture. Evolve existing configuration services and platforms through regular refactoring and decomposition while delivering incremental customer value. Collaborate closely with other engineering, product, and customer‑facing teams to design configuration models and APIs that are flexible enough for new security use cases while safe and operable in production. Continuously learn and adopt new technologies and architectural patterns that help us scale configuration management to hundreds of millions of configurations and requests per second while keeping the system observable and operable. Mentor and grow the engineering team, providing technical guidance, conducting design reviews, and fostering an environment of continuous learning and high-quality code standards. Your Toolkit: Our new components are primarily developed in Java, while our current backend uses Go and Python. Communication between microservices is facilitated using gRPC, REST, GraphQL APIs, and Kafka, depending on specific

requirements. We use PostgreSQL and ClickHouse for efficient event and configuration state storage and retrieval at scale. Our services are deployed across multiple AWS/GCP regions with Kubernetes; among other tools, you’ll also use Docker, GitHub, and ArgoCD. You’ll have access to modern AI‑powered tools to accelerate development, debugging, design exploration, and operational work. What Skills and Knowledge Will You Bring? Ideal candidates will have: Multiple years of professional backend development experience in Java as the primary language , ideally complemented by experience with Go and/or Python. Ability to quickly dive into new products and understand their inner workings. Self‑driven individual who takes end‑to‑end ownership. Experience with large‑scale high‑load distributed systems & performance. Experience with AWS and/or GCP, managing containerized workloads via Kubernetes and Docker, and building microservices with gRPC, REST, GraphQL APIs, and Kafka, backed by PostgreSQL and ClickHouse.
