We are seeking a highly skilled Senior Java Full Stack Developer with strong expertise in Spring Boot, AngularJS, and AWS to design, develop, and maintain scalable enterprise-grade applications. The ideal candidate will have solid experience across front-end and back-end technologies and real production experience making scaling, encryption, and API design decisions in high-volume streaming systems

This role involves collaborating with cross-functional teams, optimizing application performance, and contributing to the continuous improvement of our development and deployment processes.

What You'll Be Doing:

• Hands-on Development: Lead the development of critical backend components, moving seamlessly between high-level design and low-level code optimization.
• System Optimization: Identify and resolve latency bottlenecks in complex workflows, such as optimizing database sub-queries and synchronous calls.
• Secret Management: Securely manage sensitive credentials using Kubernetes Secrets or Vault solutions.
• Quality Assurance: Drive a culture of testing via JUnit, Mockito, and performance benchmarking with JMeter

Why Join Us:

• Be part of a rapidly rising, global technology innovator whose platforms and services are engaged by Fortune 1000 companies and industry leaders such as Microsoft & Amazon.
• Immerse yourself in a culture where creativity is celebrated and encouraged.

Experience Required:

• 14+ years of relevant professional experience in full-stack Java development .

Key Skills and Knowledge:

•  Java & Frameworks: Expert-level Java 11+ and Spring Boot, with deep experience in CompletableFuture for non-blocking parallel processing.
• Cloud-Native Infrastructure: Proficiency in AWS (EKS, Lambda, MSK) and Kubernetes (K8s), specifically managing pods, replicas, and horizontal scaling.
• Messaging & Streaming: Expertise in Apache Kafka (partitions, consumer groups, compression) and Apache Flink for real-time streaming analytics.
• Security & Data Integrity: Proven ability to implement idempotency and KMS envelope encryption for massive data migrations (100M+ records).
• API Architecture: Experience designing RESTful APIs using API Gateways for rate limiting, throttling, and resilience patterns like circuit breakers.

Critical "Trade-off" Skills

• Pragmatic Scaling: Knowing when to utilize auto-scaling versus manual intervention for specific streaming jobs.
• Encryption Strategy: Determining when to encrypt at the record level versus block/chunk level based on performance vs. security needs.
• Protocol Selection: Making informed decisions on HTTP methods (POST vs. PUT) and communication patterns based on the specific business use case.

Education:

• Bachelor's degree in Computer Science, Electrical Engineering, or related field.
