Job Title: Application Architect – Performance, Scalability & AI Focus

Location: Bangalore

Job Type: Full-time

Experience Level: 10+ years preferred

Job Summary:

We are seeking a seasoned Application Architect to lead the modernization, performance tuning, and security of our enterprise financial application. This role is critical in driving re-engineering of legacy systems, solving performance and latency issues, and delivering scalable, cloud-native solutions.

The ideal candidate will provide hands-on guidance across a multi-language tech stack (Java, Node.js, Angular, Ruby), and bring deep knowledge in cloud architecture (AWS), DevOps, AI/ML, and secure development practices.

Key Responsibilities:

  • Lead the refactoring and modernization of legacy financial systems into high-performing, scalable, and maintainable architectures using modern technologies.
  • Own system-wide performance analysis and optimization — from backend APIs to frontend load times.
  • Provide expert architectural guidance across development teams working in Java, Angular, Node.js, and Ruby.
  • Architect robust, low-latency solutions leveraging caching (Redis, Memcached) and messaging/queuing systems (Kafka, RabbitMQ, AWS SQS/SNS).
  • Define scalable architectures on AWS cloud using services like EC2, Lambda, RDS, DynamoDB, API Gateway, and more.
  • Collaborate with DevOps teams to ensure reliable, high-performing CI/CD pipelines and infrastructure.
  • Build and enforce observability standards — implement APM, monitoring, distributed tracing, and alerting strategies.
  • Ensure compliance with security, data privacy, and industry regulations (SOC 2, ISO 27001, etc.).
  • Identify opportunities for AI/ML integration to enhance automation, analytics, and intelligent decision-making.
  • Mentor developers, conduct code/architecture reviews, and define reusable design patterns.

Required Qualifications:

  • 10+ years of experience in software engineering and architecture roles.
  • Proven success in re-engineering/refactoring legacy systems into scalable, modern cloud-based applications.
  • Strong knowledge of Java, Angular, Node.js, and Ruby architectures.
  • Hands-on experience resolving performance and latency bottlenecks across large-scale systems.
  • Deep understanding of caching, asynchronous processing, messaging patterns, and modern integration practices.
  • Extensive experience with AWS services, infrastructure as code, and cloud-native patterns.
  • Solid grounding in DevOps, CI/CD, containerization, and microservices.
  • Strong understanding of AI/ML concepts and integration strategies.
  • Familiarity with information security principles, secure coding, and threat modeling.
  • Excellent communication and collaboration skills to lead cross-functional teams.

Preferred Qualifications:

  • AWS Certified Architect or equivalent certifications.
  • Experience in AI/ML productization using platforms like SageMaker, TensorFlow, or third-party APIs.
  • Experience with Kubernetes, service mesh, GraphQL, and WebSockets.
  • Experience modernizing monoliths to microservices or serverless.
  • Prior work in financial services, banking, or fintech domains.
