Performance Engineer

Job Title: Performance Engineer (SDET-2/3)

Experience: 4 – 6 years

About the Role:

We are looking for a Performance Engineer to join our engineering team and ensure the

scalability, reliability, and performance of our applications and infrastructure. You will play a key

role in benchmarking, profiling, and identifying bottlenecks across our systems. Your expertise

will directly contribute to delivering smooth and responsive experiences to our users.

️ What You’ll Do:

● Own the performance strategy—build and run load tests using tools like Locust, k6, or

Gatling.

● Benchmark APIs, profile backend services, and optimize system-level bottlenecks.

● Dive deep into logs and metrics (ELK, Prometheus, Grafana) to find performance issues.

● Work closely with engineering teams to design for scalability from day one.

● Tune databases (MySQL, Redis, MongoDB), queues (Kafka/RabbitMQ), and caching

layers.

● Set up performance testing in CI pipelines so we never miss regressions.

● Help define and monitor SLAs, SLOs, and alerting thresholds.

✅ You Should Have:

● 3–6 years of experience in performance testing and optimization.

● Strong grasp of HTTP, REST APIs, and backend performance fundamentals.

● Hands-on with any of these languages— Python, Go, or Java.

● Experience with APM tools like New Relic, AppDynamics, or Datadog.

● Familiarity with AWS / GCP, Kubernetes, and cloud-native observability.

💡 Nice to Have:

● Worked on a high-scale product (e.g., fintech, social, mobility, or ecommerce).

● Experience with asynchronous systems, circuit breakers, and rate-limiting.

● Experience debugging weird slowdowns and memory/cpu spikes in prod.
