About the Position

We are seeking an experienced Full Stack Developer (React+Python) 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.

Responsibilities

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

Requirements

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

We Offer

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
