• Champion best practices in software engineering, DevOps, and code quality across the team.
• Evaluate emerging technologies and assess AI tooling/libraries (e.g., Hugging Face, LangChain, TensorFlow, OpenAI).
• Drive performance optimisation of existing services and refactor legacy code as needed.
• Influence product and system design through deep understanding of scalability and AI augmentation.
• Mentor junior and mid-level developers; lead technical design reviews and code walkthroughs.

Key Requirements:

• 10+ years of professional experience in Java backend development.
• Microservices and Kubernetes
• Expert-level skills in Java, Spring Boot, REST APIs, microservices architecture, and asynchronous systems.
• Experience integrating AI/ML features into production systems (e.g., chatbots, NLP, anomaly detection, recommender systems).
• Hands-on exposure to AI frameworks or platforms: OpenAI APIs, Hugging Face Transformers, LangChain, PyTorch/TensorFlow, etc.
• Proficient with CI/CD pipelines, Docker, Kubernetes, and cloud platforms (AWS/GCP/Azure).
• Strong understanding of databases (SQL & NoSQL), distributed systems, and caching mechanisms.
• Proven experience in leading teams, conducting design reviews, and owning production-critical systems.

The median wage is the salary of a given occupation where half the workers earn more than that amount, and half earn less. This information is presented on job postings to help job seekers determine how the salary compares to the amount earned by other workers working the same job. Job Bank preferred indicating the median wage, which is less affected by extremely high or low wages, rather than the average wage which is calculated by adding up all the salaries of a group of people and then dividing that total by the number of people.
