Frontend Engineering Collaborate with UX and product teams to create human-in-the-loop AI experiences with Angular and React. Implement robust state management (Redux, NgRx, or equivalent) for real-time, data-intensive applications. Optimize rendering, bundle size, and performance for enterprise-scale UIs. Lead UI testing (Jest, Cypress, Playwright, Jasmine, Karma) to maintain quality and reliability.
Collaboration & Leadership
Work closely with cross-functional teams to deliver cohesive GenAI-powered products. Mentor junior developers, promote coding standards, and drive best practices across front-end and back-end development. Communicate effectively with technical and non-technical stakeholders, ensuring transparency and alignment.  Qualifications
  • 7+ years of professional experience as a full stack or combined backend/frontend engineer. 
  • Backend expertise: 
  • Strong skills in Java and Python, with experience in microservices and distributed systems. 
  • Deep knowledge of FastAPI, OpenAPI, gRPC, and asynchronous workflows. 
  • Proficiency with SQL and NoSQL databases, distributed computing (Kafka, Redis, RabbitMQ), and performance optimization. 
  • Frontend expertise: 
  • Expert-level experience with Angular and React, including TypeScript, JavaScript (ES6+), HTML5, CSS3/SASS. 
  • Strong grasp of state management frameworks (Redux, NgRx, etc.). 
  • Proven ability to build responsive, accessible, and performant enterprise UIs. 
  • Cloud & DevOps: Hands-on with AWS/Azure/GCP, Docker, Kubernetes, and CI/CD pipelines. 
  • Strong understanding of security best practices across the stack. 
  • Excellent collaboration, problem-solving, and communication skills. 
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
