Full Stack Developer; React+Python

We are looking for an experienced Full Stack Developer to build privacy-preserving, decentralized biometric authentication systems. You’ll play a key role in designing and developing secure, scalable, and high-performance features across a next-generation SaaS platform that enables organizations to secure digital identities without ever exposing raw biometric data. If you enjoy working with cutting-edge cryptography, distributed systems, and meaningful products – this role is for you.

• Design, develop, and maintain full-stack applications using React (frontend) and Python (backend – FastAPI/Flask)
• Collaborate with product and design teams to deliver intuitive, privacy-centric user experiences
• Build and maintain integrations with distributed backend services and biometric SDKs
• Optimize performance, reliability, and scalability in a multi-tenant SaaS environment
• Contribute to architectural decisions and promote best practices in code quality and security
• Write clean, testable, maintainable code and participate in code reviews

• 5+ years of professional full stack development experience
• Deep expertise in React (including hooks, context, and component design patterns)
• Strong backend experience with Python web frameworks (FastAPI, Flask, or Django)
• Proven track record in SaaS environments
• Solid understanding of RESTful API design, microservices, and cloud-native principles
• Familiarity with CI/CD pipelines, Docker, and cloud platforms (AWS, GCP, or Azure)
• Experience in building high-security, privacy-first systems is a strong plus
• Excellent communication skills and a proactive, ownership-driven mindset
• Knowledge of Web Authn, cryptography, or biometric authentication will be an advantage
• Experience with PostgreSQL, Redis, and message brokers (e.g., RabbitMQ, Kafka) will be a plus
• Background in cybersecurity or identity management – nice to have

• Opportunity to become an integral part of a long-term engineering team working on an innovative and secure product
• Influence on technical decisions and product architecture
• Competitive compensation based on experience and results
• Direct communication with stakeholders and seamless integration into the development process
• A professional environment that values ownership, code quality, and continuous growth
