Principal Backend / Platform Engineer (Cybersecurity)

We are seeking an exceptionally talented Principal Backend / Platform Engineer (Cybersecurity) to join our rapidly growing team.

We’re building a next-generation cybersecurity product that protects users from social engineering attacks across all communication channels. The system combines a client-side agent with a cloud platform that performs real-time analysis under strict privacy constraints.

This is a high-ownership role where you will design and own the cloud-side architecture, spanning real-time systems, data pipelines, and platform infrastructure.

Own the cloud platform architecture end-to-end, including design, scalability, and reliability 
Design and implement low-latency real-time detection pipelines (client → cloud → response)  
Build and maintain data ingestion and processing systems ensuring high data quality and clean interfaces with ML systems 
Develop admin and control-plane backends, including internal tooling and customer-facing APIs (multi-tenant, RBAC, auditability)  
Design and enforce privacy-first systems, ensuring sensitive data is processed securely without unnecessary storage  
Own platform infrastructure, including Azure cloud architecture, CI/CD pipelines, and Infrastructure as Code  
Establish observability, reliability standards, and system health monitoring  
Design and enforce end-to-end security, including platform hardening and supply chain security 

  

Strong experience designing distributed backend systems 
Deep familiarity with cloud platforms (preferably Microsoft Azure)  
Experience with databases such as PostgreSQL and Redis  
Experience building data pipelines or real-time processing systems
Strong understanding of security and privacy in system design 
Ability to own architecture end-to-end with minimal oversight 
Experience in cybersecurity or privacy-sensitive products 
Familiarity with ML/AI systems (supporting, not necessarily building models)  
Experience designing multi-tenant SaaS platforms  
Exposure to streaming systems or event-driven architectures
