A seed-stage AI security firm protecting enterprises from email-based account takeovers.
Staff Software Engineer (Backend / Distributed Systems)
We need a backend architect who finds elegance in high-throughput distributed systems and feels genuine urgency about stopping Business Email Compromise before it happens. You will design the core detection engine that analyzes millions of Microsoft 365 events in real time, balancing low-latency inference with the rigor required for security-critical infrastructure. This is not a maintenance role; you are building the foundational logic that separates legitimate traffic from sophisticated AI-driven attacks.
What they're looking for
- 5 to 8 years of experience building scalable backend services using Go, Rust, or C++.
- Deep expertise in distributed system patterns, event streaming, and low-latency data processing.
- Proven track record in cybersecurity, threat detection, or high-stakes B2B infrastructure.
- Ability to thrive in a small, focused team within an on-site San Francisco environment.
