Job title: Back End Developer

Key responsibilities:

Design, develop, and maintain highly scalable and robust Java-based microservices using Spring Boot.

• Take full ownership of system architecture, design patterns, and end-to-end design decisions.

• Write high-performance code applying advanced data structures and algorithms for real-world large data challenges.

• Design and implement caching strategies and low-latency data pipelines using Redis.

• Develop and deploy containerized services using Docker and orchestrate them via Kubernetes.

• Lead the technical direction on projects including system design, database schema design, and performance tuning.

• Collaborate with product teams and other engineers to convert product requirements into scalable, production-ready solutions.
