Sr Software Engineer

Role Overview

We are seeking an experienced Software Engineer to join our core engineering team. You will design and develop a high-throughput, mission-critical active-active microservice framework responsible for dynamically routing and balancing traffic across multi-site deployments based on real-time health, capacity, and geolocation metrics.

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.

Required Skills & Experience

You will need deep hands-on experience in Golang (preferred) or proficiency in C/C++/Java. Strong computer science fundamentals, including data structures, algorithms, distributed systems, multi-threading, concurrency control, and Finite State Machines are essential.

• Hands-on expertise with networking and messaging protocols: gRPC, Protobuf v3, RabbitMQ.
• Strong background with distributed databases like Apache Ignite/GridGain and consensus tools like Consul Raft/LockAuthority.
• Practical knowledge of persistence/caching solutions such as PostgreSQL, Redis, ElasticSearch.
• Excellent communication skills for technical documentation.
• Industry Experience: 1 to 10 years.

Basic Requirements

• Proven ability to design active-active multi-site architectures handling network partitions and site-isolation scenarios.
• Experience with large-volume transaction systems, data migration workflows, and observability frameworks like OpenTelemetry/Kibana.
• Familiarity with enterprise security tooling such as Vault/mTLS.
• Background in automated deployments using Docker/CI/CD pipelines.
