About Us

Were a growing company with a high-concurrency application built on a modern stack. Our platform serves thousands of users simultaneously, and performance at scale is critical to our success. Were looking for a Senior Performance & Reliability Engineer to help diagnose bottlenecks, optimize system performance, and guide our transition from PHP to Java in a cloud-native environment.

What You'll Do

  • End-to-End Performance Engineering

  • Profile and optimize application performance across Java, PHP, and Angular services.

  • Tune JVM, garbage collection, and thread management for high concurrency.

  • Guide the transition from PHP to Java with performance best practices.

  • Database & Storage Optimization

  • Analyze and optimize MySQL queries, indexes, and schema design.

  • Implement caching strategies (Redis, Memcached, etc.) to reduce DB load.

  • Optimize usage of Azure Table Storage (partitioning, throughput, access patterns).

  • Cloud & Infrastructure Reliability

  • Configure and tune Kubernetes (HPA, pod resources, networking, ingress controllers).

  • Troubleshoot Docker container performance issues.

  • Ensure high availability and scalability on Azure.

  • Observability & Diagnostics

  • Set up and manage performance monitoring and distributed tracing (Prometheus, Grafana, OpenTelemetry, Jaeger, Datadog/New Relic).

  • Define and monitor SLAs, SLOs, and SLIs.

  • Build automated performance tests and load/stress scenarios.

  • Collaboration & Leadership

  • Work with backend/frontend teams to embed performance considerations into development.

  • Provide best practices, mentorship, and knowledge transfer to in-house developers.
  • Act as the go-to expert for performance fire-fighting in production.

What Were Looking For

  • Must-Have Skills:

  • Strong experience with Java performance tuning (JVM internals, GC, multithreading).

  • PHP application profiling and optimization experience.
  • MySQL query optimization and schema design expertise.
  • Hands-on with Docker & Kubernetes (scaling, debugging, autoscaling).
  • Strong grasp of observability stacks (Prometheus, Grafana, APM tools).

  • Experience in cloud platforms (Azure preferred).

  • Nice-to-Have Skills:

  • Angular front-end performance optimization.

  • Experience with caching systems (Redis, Memcached, CDN).
  • Knowledge of CI/CD pipelines for performance regression testing.

  • Familiarity with microservices architectures and message queues (Kafka, RabbitMQ).

  • Soft Skills:

  • Analytical, evidence-driven approach (measure before acting).

  • Ability to communicate trade-offs clearly to devs and management.
  • Experience working with cross-functional engineering teams.

Engagement Model

Were open to:

  • Full-time role: For someone who wants to own performance long-term and be part of our core team. Needs to be open to a lot of hands-on coding.
  • Consulting/Contract role: For experts who prefer to audit, diagnose, and guide on-demand. We will pay upto Rs. 8,000 per day, and more for deserving persons.

Why Join Us?

  • Work on a challenging, high-traffic product where performance makes a real difference.
  • Shape our next-generation architecture as we migrate from PHP to Java.
  • Freedom to introduce modern tools and practices for observability and scaling.
  • Flexible engagement — we value expertise over fixed labels.
