Founding Engineer

About the Role

Join an early-stage cybersecurity team building systems to monitor and secure enterprise AI deployments. You will help shape the platform's architecture and deliver production features directly to enterprise customers.

What You'll Do

  • Own features end to end and ship them into production for enterprise customers.

  • Build data infrastructure that ingests high-volume telemetry from endpoint, network, identity, and AI model systems.

  • Develop real-time detection and policy enforcement for emerging risks in AI agents.

  • Work with customers during proofs of concept and deployments, adapting and delivering features as needed.

  • Train small models to make low-latency decisions based on behavioral baselines.

  • Red-team AI models and agents to identify issues such as prompt injection, tool misuse, data exfiltration, and scope drift.

  • Help define the platform architecture and technical direction.

What We're Looking For

  • 0 to 5 years of software engineering experience, including internships, with a focus on backend or full-stack development.

  • Strong backend and systems fundamentals, including experience with distributed systems, infrastructure, or production services at scale.

  • Experience delivering production systems and working in a startup or other fast-paced engineering environment.

  • Familiarity with Go or Rust, streaming pipelines, real-time data infrastructure, cloud infrastructure, and integrations with endpoint security tools.

  • Background in cybersecurity, security engineering, adversarial testing, applied machine learning, model fine-tuning, or post-training is valuable.

  • Customer-facing engineering experience, competitive programming, or quantitative engineering experience is a plus.
