Your Role:

We are looking for a Scale & Performance Engineerto drive the performance, scalability, and reliability initiatives for ourObservability Platformthat ingests, processes, and visualizes large volumes of telemetry data (metrics, logs, and traces).

You will work closely with platform, SRE, frontend and backend teams to benchmark system performance, optimize bottlenecks, and ensure the platform scales efficiently to meet growing customer and data demands.

This role is ideal for engineers who are passionate about high-performance distributed systems,Kubernetes, andobservability stack performance(Prometheus, OpenTelemetry, Loki, Grafana, etc.).

Are you excited to be a part of VuNet's trailblazing team Join VuNet and make a difference

Roles & Responsibilities

• Ownperformance and scalability benchmarkingfor the Observability Platform components ingestion pipeline, data storage, and query services.
• Design and execute load, stress, soak, and capacity testsfor microservices, agents, and ingestion layers.
• Identify performance bottlenecks across infrastructure (CPU/memory/IO)andapplication layers (API latency, throughput, GC behavior, etc.).
• Develop and maintainperformance test frameworksandbenchmarking environments(preferably Kubernetes-based).
• Partner with DevOps and SRE teams to tune system configurations (Kubernetes, Postgres/TimescaleDB, ClickHouse, Kafka, etc.) for scale.
• Instrument services withOpenTelemetry metrics and tracesto measure system health and latency distribution (p50/p95/p99).
• Contribute tocapacityplanning,horizontal/vertical scaling strategy, andresource optimization.
• Analyze production incidents for scale-related root causes and drive permanent fixes.
• Collaborate with engineering teams to designscalable architecture patternsanddefine SLIs/SLOsfor system performance.
• Document performance baselines, tuning guides, and scalability best practices.

Mandatory Skills

• Strong background in performance engineeringfor large-scale distributed systems or SaaS platforms.
• Expertisein Kubernetes, container runtime (container/Docker), and resource profilingin containerized environments.
• Solid knowledge of Linux internals, CPU/memory profiling, and network stack tuning.
• Hands-on experience with observability tools Prometheus, Grafana, OpenTelemetry, Jaeger, Loki, Tempo, etc.
• Familiaritywith datastoresused in observability platforms e.g., ClickHouse, PostgreSQL/TimescaleDB, Elasticsearch, or Cassandra.
• Experience building and executing performance benchmarking frameworksusing tools like k6, Locust, JMeter, or custom Golang/Python scripts.
• Ability to interpret metrics (CPU usage, memory, GC, latency) and correlate across systems.
• Strong analytical and problem-solving skills with an automation-first mindset.

Good to Have Skills

• Experience with agent benchmarking(OpenTelemetry Collector, custom data shippers).
• Exposure to streaming systemslike Kafka, NATS, or Pulsar.
• Experience with CI/CD pipelinesfor performance testing and regression tracking.
• Understanding ofcost optimization and capacity forecastingin cloud environments (AWS/GCP/Azure).
• Proficiency in Go, Python, or Bash scriptingfor automation and data analysis.
