About the role
We are seeking a highly experienced (10+ years) Java Full‑Stack Lead Developer with strong system architecture expertise to lead the design and delivery of scalable, distributed systems. This is a hands‑on leadership role where you will define architecture, guide a globally distributed engineering team, and ensure high standards in both backend and frontend development.
Key Responsibilities
* Lead the architecture design of complex, scalable and high‑availability systems
* Make critical decisions on system design, tech stack, and trade‑offs
* Drive end‑to‑end development across backend and frontend (hands‑on coding required)
* Lead and coordinate a globally distributed team across different time zones
* Establish and enforce engineering best practices, coding standards, and design principles
* Conduct design reviews, code reviews, and architecture governance
* Optimize system performance, scalability, and reliability
* Troubleshoot and resolve complex production and distributed system issues
* Collaborate with product, design, and business stakeholders globally
Architecture & System Design (Must‑Have)

* Fault tolerance and resilience design
* Experience with system decomposition and domain modelling
Backend
* Expert‑level proficiency in Java (8/11/17+)
* Strong experience with Spring Boot / Spring Cloud
* Deep understanding of RESTful APIs and microservices
* Experience with ORM frameworks (Hibernate, JPA)
Frontend
* Strong hands‑on experience with at least one: React / Vue / Angular
* Solid understanding of frontend architecture and state management
* Ability to contribute to frontend system design (not just coding)
Data & Infrastructure

* Experience with Redis or distributed caching
* Message queues (Kafka / RabbitMQ)
* Familiar with Docker, Kubernetes
* CI/CD and automated deployment pipelines
Excellent project management skills with a track record of successfully leading large‑scale initiatives preferred.
Nice to Have (Strong Differentiators)

* Experience designing multi‑region or global systems
* Exposure to AI systems (LLM, RAG, vector databases)
* Experience with observability (metrics, tracing, logging systems)
