Backend Software Engineer (AI Account Security)

A fast-growing cybersecurity startup whose AI detection platform protects millions of users from account takeover is looking for a backend and distributed systems engineer to own core infrastructure from day one.

Your focus

• Build real-time systems that detect compromised accounts, from signal ingestion through behavioral analysis to AI-driven decisions
• Design backend infrastructure that can absorb 10 to 100 times more load over the coming months
• Put ML and AI-integrated systems into production rather than leaving them as prototypes
• Set engineering patterns and raise the technical bar for a small, senior team
• Partner directly with the founders on the direction of the core platform

What you bring

• 4 to 8 years of backend or distributed systems engineering
• Experience building high-stakes, data-intensive systems end to end, such as real-time ingestion pipelines and distributed processing
• Depth in distributed systems architecture and database scaling
• Startup experience with broad ownership and a habit of scoping and shipping on your own
• A CS degree from a top US program; quant or trading backgrounds are welcome
