Infrastructure Engineer - Scalability & Performance

At TrueLark, our infrastructure powers mission-critical business applications for customers across industries. As we continue to grow, we need a Scaling Engineer who can design and implement scalable, high-performance infrastructure solutions.

You will focus on optimizing performance, improving system resilience, and scaling our services built on Redis, MySQL, ActiveMQ, and Jetty Spark servers. This is a highly impactful role where you will collaborate with engineering and DevOps teams to ensure our systems perform reliably under heavy load.

• This position will be (remote, in office, hybrid (remote/in office))

• Reports to: Head of TrueLark Technology

What You Will Own

• Infrastructure Scaling & Optimization: Analyze current infrastructure and design solutions to handle increasing load with high availability.

• Database Performance Tuning: Optimize MySQL (indexes, queries, partitioning, replication, sharding) and Redis caching strategies for throughput and latency improvements.

• Message Queue Scaling: Enhance and optimize ActiveMQ for large-scale, distributed messaging with high durability and reliability.

• Server & Application Scaling: Tune Jetty Spark servers for concurrency, session management, load balancing, and failover strategies.

• Monitoring & Bottleneck Detection: Implement monitoring dashboards (Grafana, Prometheus, ELK/EFK, or Azure Monitor) to detect slow queries, CPU/memory bottlenecks, and scaling issues.

• Distributed Systems Reliability: Ensure fault tolerance, disaster recovery, and horizontal scaling strategies.

• CI/CD & Automation: Work with GitHub Actions, Jenkins, or Azure DevOps for automated deployments and scaling workflows.

• Collaboration: Partner with backend engineers, DevOps, and product teams to deliver reliable infrastructure that meets performance goals.

What You Will Need to Accomplish the Job

• Bachelor’s degree in Computer Science, Information Technology, or related field.

• 3+ years of experience in scaling infrastructure for distributed systems or high-traffic applications.

• Strong hands-on experience with:

  • Databases: MySQL (query optimization, replication, partitioning, indexing strategies).

  • Caching: Redis (cluster setup, pub/sub, eviction policies, memory optimization).

  • Message Queues: ActiveMQ (scaling consumers/producers, HA clusters, performance tuning).

  • Web Servers: Jetty with Spark framework (thread pools, tuning JVM, load balancing).

• Proficiency in monitoring & observability tools (Grafana, Prometheus, ELK/EFK stack, Azure Monitor, or DataDog).

• Knowledge of distributed systems principles (CAP theorem, sharding, replication, consensus).

• Familiarity with CI/CD pipelines, Docker, Kubernetes (AKS/EKS/GKE optional).

• Strong problem-solving skills in debugging production performance bottlenecks.

• Ability to work independently and collaboratively in a fast-paced environment.

What Will Make Us Love You

• Experience with horizontal scaling of microservices in production.

• Knowledge of cloud platforms (Azure, AWS, GCP) for scaling and infrastructure automation.

• Hands-on experience with load testing tools (JMeter, Locust, k6, Artillery).

• Familiarity with event-driven architecture and streaming platforms (Kafka).

• Contributions to open-source performance/scaling projects
