Senior Performance & Reliability Engineer (Java / PHP / Cloud)

About Us

Senior Performance & Reliability Engineer

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.
