Your Role: Lead Software Engineer - Scale & Performance

As a Lead Software Engineer for Scale & Performance, you ll own the performance and scalability benchmarks for VuNet s observability platform. You will work with cutting-edge technologies, design robust test frameworks, and ensure that our platform scales seamlessly to meet the demands of millions of users.

Roles & Responsibilities

• Own performance and scalability benchmarking for key platform components (ingestion pipelines, data storage, and query services).
• Design and execute load, stress, soak, and capacity tests across microservices, agents, and ingestion layers.
• Identify and resolve performance bottlenecks in both infrastructure (CPU/memory/IO) and application layers (API latency, throughput, GC behavior).
• Develop and maintain performance test frameworks, preferably using Kubernetes-based environments.
• Collaborate with DevOps and SRE teams to optimize system configurations (Kubernetes, Postgres/TimescaleDB, ClickHouse, Kafka) for scale.
• Implement OpenTelemetry for service instrumentation to monitor system health and latency (p50/p95/p99 metrics).
• Contribute to capacity planning, scaling strategies (horizontal/vertical), and resource optimization.
• Analyze production incidents related to scaling issues and drive permanent fixes.
• Work with engineering teams to design scalable architecture patterns and define SLIs/SLOs for system performance.
• Document performance baselines, tuning guides, and scalability best practices for internal use.

What You Bring

Mandatory Skills:

• Strong background in performance engineering for large-scale distributed systems or SaaS platforms.
• Expertise in Kubernetes, container runtimes (containerd/Docker), and resource profiling in containerized environments.
• Solid understanding of Linux internals, CPU/memory profiling, and network stack tuning.
• Hands-on experience with observability tools (Prometheus, Grafana, OpenTelemetry, Jaeger, Loki, Tempo, etc.).
• Familiarity with observability platform datastores like ClickHouse, PostgreSQL/TimescaleDB, Elasticsearch, or Cassandra.
• Experience with performance benchmarking tools such as k6, Locust, JMeter, or custom Golang/Python scripts.
• Ability to interpret system metrics (CPU usage, memory, GC, latency) and correlate across different layers.

Nice-to-Have Skills:

• Experience with agent benchmarking (OpenTelemetry Collector, custom data shippers).
• Exposure to streaming systems like Kafka, NATS, or Pulsar.
• Familiarity with CI/CD pipelines for performance testing and regression tracking.
• Knowledge of cost optimization and capacity forecasting in cloud environments (AWS/GCP/Azure).
• Proficiency in Go, Python, or Bash scripting for automation and data analysis.
