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 WebAuthn, 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
