Job Summary

  • We are seeking an experienced engineer who can analyze, diagnose, and optimize performance and reliability of large-scale distributed systems. This role requires deep technical understanding across the entire application stack, the ability to read and reason about code, and the capability to provide data-backed answers to both engineering teams and business stakeholders.
  • This role goes beyond traditional operations or DevOps. The successful candidate will think like a software engineer, act like a systems engineer, and operate with a production-first mindset.

Key Responsibilities

  • Performance & Reliability Engineering
  • Analyze and resolve performance issues such as high latency, slow login, throughput degradation, and system instability.
  • Perform deep, end-to-end investigations across the full stack including:
  • Load balancers and traffic routing
  • Web server and application runtime configurations
  • Middleware and messaging systems
  • Database performance (queries, indexing, pooling)
  • Kubernetes clusters (pods, resources, scaling behavior)
  • Linux OS tuning (CPU, memory, I/O, ulimits, networking)
  • Identify root causes and propose clear, actionable engineering solutions.
  • Distributed Systems Design
  • Design, review, and influence high-performance, highly-available distributed architectures.
  • Evaluate trade-offs related to scalability, latency, fault tolerance, and cost.
  • Partner with development teams early to prevent reliability and performance issues before production.
  • Capacity Planning & Scalability
  • Assess system readiness for growth scenarios such as:
  • “We plan to onboard 10,000 users in 6 months — can the system support it?”
  • Perform capacity and scale analysis for:
  • Application tiers
  • Databases
  • Messaging systems
  • Kubernetes compute and storage
  • Provide evidence-based recommendations supported by metrics, benchmarks, and production data.
  • Engineering Collaboration
  • Work closely with software engineering teams to:
  • Review performance-critical code paths
  • Propose improvements at code, configuration, or infrastructure level
  • Improve system observability (metrics, logs, traces)
  • Communicate complex technical findings clearly to both engineers and business stakeholders.
  • Required Technical Skills
  • Strong understanding of distributed systems and performance engineering
  • Ability to read, analyze, and troubleshoot Java code
  • Hands-on experience with:
  • Kubernetes (resource management, scaling, container behavior)
  • Linux internals and tuning
  • PostgreSQL (queries, indexing, performance optimization)
  • Proven experience building or operating high-availability, high-throughput systems
  • Strong analytical and problem-solving skills with a data-driven approach
  • Nice to Have
  • Experience with Azure cloud services
  • Messaging systems such as ActiveMQ
  • Load testing and benchmarking experience
  • Background in roles such as SRE, Performance Engineering, Platform Engineering
