The position is for a Senior Java Engineer / Architect specializing in high-volume, data-intensive systems. The focus is on designing and building secure, scalable, and reliable microservices that process real-time streaming data.

Responsibilities:

• Design & Development: Architect, implement, and maintain Java microservices processing high-volume data streams.
• Pipeline Engineering: Build and optimize ingestion pipelines (Kafka, Flink, Beam etc.) to ensure low-latency, high-throughput data flow.
• Secure Coding: Embed secure coding standards (OWASP, SAST/DAST integration, threat modeling) into the SDLC; implement authentication, authorization, encryption, and audit logging.
• Performance at Scale: Identify and resolve performance bottlenecks (JVM tuning, GC optimization, resource profiling) in distributed environments.
• Reliability & Monitoring: Develop health checks, metrics, and alerts (Prometheus/Grafana), and instrument distributed tracing (OpenTelemetry).
• Collaboration: Work closely with product managers, data engineers, SREs, and security teams to plan features, review designs, and conduct security/code reviews.
• Continuous Improvement: Champion CI/CD best practices (GitOps, automated testing, blue/green deployments) and mentor peers in code quality and performance tuning.

Qualifications

• Bachelor's or Master's in Computer Science, Engineering, or related field.
• 6–10 years of software development experience, with at least 3 years focused on data-intensive applications.
• Demonstrated contributions to production-critical systems serving thousands of TPS (transactions per second).
• Strong analytical and problem-solving skills; comfortable working in fast-paced, agile environments.

Required Skills

• Strong Java Expertise: 8+ years of hands-on experience with Java 11+; deep knowledge of concurrency, memory management, and JVM internals.
• Secure Coding Practices: Proven track record implementing OWASP Top Ten mitigations, performing threat modeling, and integrating SAST/DAST tools.
• Big Data & Streaming: Hands-on with Kafka (producers/consumers, schema registry), Spark or Flink for stream/batch processing.
• System Design at Scale: Experience designing distributed systems (microservices, service mesh) with high availability and partition tolerance.
• DevOps & Automation: Skilled in containerization (Docker), orchestration (Kubernetes), CI/CD pipelines (Jenkins).
• Cloud Platforms: Production experience on AWS; familiarity with managed services (MSK, EMR, GKE, etc.).
• Testing & Observability: Expertise in unit/integration testing (JUnit, Mockito), performance testing (JMH), logging (ELK/EFK), and monitoring stacks.
• Collaboration & Communication: Effective communicator; able to articulate technical trade-offs and evangelize best practices across teams.

Preferred Skills

• Open source contributions to streaming or security projects.
• Experience with infrastructure as code (Terraform, CloudFormation).
