Middle Python Developer — Cloud Security & AWS

Location: Warsaw, Poland (Hybrid preferred, open to strong remote candidates within Poland)Experience: 3 yearsThe RoleWe're looking for a Backend Engineer who thrives at the intersection of high-performance systems and enterprise-grade security. You will design and build scalable microservices that power secure data pipelines, orchestrating complex integrations between cloud-native backends and mobile frontends.This is not a routine maintenance role. You will shape how organizations consume operational intelligence — from defining API contracts to optimizing real-time data flows, all while ensuring that every packet of information is authenticated, authorized, and encrypted.What You'll Build and OwnResilient Backend Services — Develop Python-based RESTful APIs and microservices that handle sensitive telemetry with millisecond latency.Secure Connectivity Fabric — Architect and administer encrypted communication channels using Spacebridge technology, enabling seamless, VPN-free mobile access to on-premises data sources.Serverless &
