Job Description

• Design and build distributed backend systems that scale reliably and securely • Work in TypeScript, Kotlin and Go (and pick them up quickly if you haven’t used them before) • Deploy and operate services in AWS and other cloud providers. • Own problems end-to-end—from design through deployment to production support • Navigate ambiguity and help define *how* we build as much as *what* we build • Collaborate closely with teammates across the stack, including AI researchers, Security researchers and frontend engineers

Job Requirements

  • Experience building and operating scalable, distributed systems
  • Comfort working in a fast-moving, early-stage environment
  • Strong problem-solving skills and the ability to work with incomplete information
  • Familiarity with AWS or similar cloud platforms
  • You’re comfortable working with infrastructure as code (e.g., Terraform or CDK) and see infra as part of the engineering system—not something separate from it.
  • Eager to learn new tools, languages, and technologies as needed
  • A thoughtful communicator who values clarity and simplicity
  • Comfort working in a fast-paced, early-stage startup environment
  • Experience with event-driven architectures, message queues, or async workflows
  • Experience designing and optimizing relational databases (we use Postgres), and you know how to structure data for both performance and clarity.
  • Background in systems programming, networking, or performance tuning
  • Experience with hybrid deployments (cloud + on-prem) and know how to build resilient systems that handle the complexity of mixed environments.
  • Experience working in an early stage startup
  • Prior experience building security products or products for technical users

Benefits

  • Competitive salary and a generous equity package, making you a true owner of the company.
  • Shape your role, lead the function, and grow with the company as we redefine cybersecurity.
  • You will tackle technically complex challenges and play a pivotal role in the growth of our business, working alongside an amazing team and some of the world’s experts to shape how AI transforms cybersecurity.
