Lead Software Engineer – Performance Engineering

About the job

As a Lead Software Engineer – Performance Engineering , you will drive the strategy, design, and execution of performance engineering initiatives across highly distributed systems. You will lead technical efforts to ensure reliability, scalability, and responsiveness of business-critical applications. This role requires deep technical expertise, hands-on performance testing experience, and the ability to mentor engineers while collaborating cross-functionally with architecture, SRE, and development teams.

Responsibilities :

• Define, implement, and enforce SLAs, SLOs, and performance benchmarks for large-scale systems.
• Lead performance testing initiatives including load, stress, soak, chaos, and scalability testing.
• Design and build performance testing frameworks integrated into CI / CD pipelines.
• Analyze application, infrastructure, and database metrics to identify bottlenecks and recommend optimizations.
• Collaborate with cross-functional teams to influence system architecture and improve end-to-end performance.
• Guide the implementation of observability strategies using monitoring and APM tools.
• Optimize cloud infrastructure (e.g., autoscaling, caching, network tuning) for cost-efficiency and speed.
• Tune databases and messaging systems (e.g., PostgreSQL, Kafka, Redis) for high throughput and low latency.
• Mentor engineers and foster a performance-first culture across teams.
• Lead incident response and postmortem processes related to performance issues.
• Drive continuous improvement initiatives using data-driven insights and operational feedback.
