The team processes millions of authorization decisions per second and collaborates across multiple product groups to deliver critical security infrastructure.
You will lead backend engineering efforts from prototyping through large-scale production deployment. Key responsibilities include architecting and building cloud-based systems for threat detection and cyber intelligence automation at global scale, collaborating cross-functionally to define and implement solutions, and mentoring other developers on backend, web, and data storage technologies. You'll continuously evaluate and improve system architecture, performance, stability, and user experience while maintaining ownership and accountability for deliverables.
The tech stack includes Go, Python, OAuth, AWS, Kafka, Cassandra, Elasticsearch, Redis, Postgres, GraphQL, and Git. You'll work with high-scale event-driven microservices architecture processing millions of events daily.
Required qualifications: 7+ years of production backend development experience (typical range 8-12 years) in cloud SaaS or service-oriented architectures using Go, Java, Scala, Node.js, Python, or C#. Strong expertise in authentication and authorization systems, high-scale event-driven microservices (5M+ events/day), distributed systems, multi-threading, concurrency, and horizontal scaling. Computer Science degree or equivalent demonstrated expertise in data structures, algorithms, and distributed systems. Proven ability to ship production code, work collaboratively in test-driven environments, and deliver high-quality software with thorough testing and code review practices. Experience leveraging AI to enhance decision-making and workflows is valued.
Bonus qualifications include fine-grained access control experience (OpenFGA, Zanzibar), authored open-source projects, GitHub/Stack Overflow contributions, and prior exposure to Go, Scala, AWS, Cassandra, Kafka, or Elasticsearch. Cybersecurity or intelligence field experience is a plus.
