Job Description

Key Responsibilities:

• Develop the core Load Distribution engine using Finite State Machines (FSM) to manage dynamic homing, execute Weighted Average Score (WAS) algorithms, and implement hysteresis.

• Architect high-throughput API and messaging layers using gRPC for metrics ingestion and RabbitMQ (RMQ) for event-driven communication.

• Implement distributed leader election and consensus mechanisms utilizing Consul Raft and LockAuthority across active-active deployments.

• Ensure system scalability to handle 3,000+ assignments per second while integrating Apache Ignite/GridGain for stateless caching and data recovery.

• Practical knowledge of persistence and caching solutions such as PostgreSQL, Redis, and ElasticSearch.

• Excellent written and verbal communication skills for technical documentation and explaining complex ideas.

• Industry Experience - 1 to 10 years.

Basic Requirements

• Proven ability to design active-active multi-site architectures handling network partitions, majority/minority quorums, and site-isolation scenarios.
