Job Title: Software Engineer specializing in Performance & Load Testing

Location: New York City NY (Hybrid)

Job Description: Our squad that needs a Software Engineer specializing in Performance & Load Testing to build next-generation traffic-replay infrastructure and scenario-generation tooling. Rather than executing manual performance tests you will build software that parses raw API/event logs converts massive exports into realistic replayable traffic profiles (utilizing LLM-assisted pipelines) and partners with engineering teams to diagnose and remediate core system bottlenecks.

Responsibilities:- Build automated tooling data parsers and custom load generators using languages like Go Python Java or Rust.- Build or customize load generation frameworks (k6 Locust Gatling or custom distributed replay tools).- Process massive datasets (JSON Parquet PCAP raw HTTP/event logs) to reconstruct stateful application workflows.- Isolate system bottlenecks using telemetry tools (Grafana Prometheus Datadog OpenTelemetry).- Understand and work with HTTP/REST WebSockets gRPC and event-driven architectures (e.g. Kafka RabbitMQ).

Required Skills:- Strong engineering background in relevant programming languages.- Deep experience with load generation frameworks.- Experience processing large datasets.- Hands-on experience with telemetry tools.- Deep understanding of various communication protocols and architectures. Preferred Skills:- Experience using LLM APIs (OpenAI Anthropic) or prompt-engineering pipelines to parse structure or generate synthetic test data from unstructured logs.- Expertise managing distributed multi-region load testing infrastructure on Kubernetes/Cloud providers (AWS/GCP/Azure).
