Some experience in React or similar and modern JavaScript/TypeScript. Solid experience with object oriented design and applying standard design patterns Experience designing, building, and deploying scalable microservices using API first principles with REST and/or gRPC. Experience with API authentication and authorization mechanisms (e.g. OAuth, JWT). Hands on experience with engineering tools such as Git, Maven, unit and integration testing frameworks, and mocking libraries. Exposure to Docker, Kubernetes, and cloud services in an enterprise environment is beneficial. Experience with message brokers such as Kafka a plus. A friendly, positive, and can do attitude.
