Our client is an established technology firm developing high-throughput, multi-tenant platforms used by institutional customers.

Lead performance tuning across messaging, compute, network, and storage layers.
Own critical platform services supporting high-volume API and UI workloads.
Collaborate with engineering leadership to shape architectural direction.

Required Experience :

10–15+ years of professional experience with extensive work in C# and .NET.

Strong experience with gRPC and cloud-based service architectures.

Expertise with distributed messaging and event-streaming technologies including Kafka, RabbitMQ, and Redis.

Strong understanding of backend fundamentals including high-volume message processing, interprocess communication patterns, and database performance.

Experience building multi-tenant, event-driven B2B systems requiring millisecond-level updates.

Experience building frameworks or shared service layers.

Strong interest in clean architecture and high engineering standards.

Non-Technical Requirements :

Strong analytical and architectural reasoning.

High ownership mindset with strong follow-through and initiative.

Ability to work independently and collaborate effectively.

Strong communication skills.

Education :

Bachelor’s degree or higher in Computer Science, Engineering, or related technical discipline preferred.

Nice to Have :

NYC metro candidates preferred for hybrid collaboration (flexible for exceptional candidates).

Benefits :

Medical, Dental, and Vision coverage

Retirement plan (401k or IRA)

Paid vacation, sick time, and holidays

Life insurance options

Short- and long-term disability coverage
