Lead Engineer

Job Summary

VSA X - Staff software engineer (backend) Role Overview We are seeking a Senior Staff Engineer to lead the architecture of a high-load distributed backend system, with strong emphasis on performance engineering, caching strategies, and efficient communication patterns(gRPC, messaging).

The system is heavilyRedis-driven with minimal reliance on database operations.

Responsibilities

• Lead architecture design for high-load distributed systems

• Define and drive cache-first architecture (Redis as core layer)

• Design efficient service communication using gRPC, REST, and messaging systems

• Define best practices for RabbitMQ/Kafka usage (throughput, reliability, ordering)

• Drive deep performance optimization across CPU, memory, network,and I/O

• Optimize inter-service communication and data flow

• Design efficient data access patterns with NHibernate

• Own performance of critical paths under high concurrency

• Establish engineering standards for high-performance C# code

• Drive adoption of AI-assisted engineering (coding agents, test generation)

• Define governance for AI-generated code quality and safety

• Mentor engineers in performance engineering and distributed systems

• Lead incident analysis focusing on performance bottlenecks and scaling limits

  Requirements

• 8+ years of backend engineering experience

• Deep expertise in C# / .NET

• Proven experience building high-load distributed systems
