As a Staff Engineer, you will lead the architecture, design, and implementation of the Third-Party Manager (TPM) platform, building secure, scalable microservices and modern, high-performance front-ends . You will drive migration from legacy Monolith Legacy systems to a modern React/ NextJS / NestJS stack, guide the Azure to AWS migration, and spearhead AI-driven initiatives, including LLMs, RAG architectures, and agentic AI use cases. Your expertise in full-stack development, platform integrations ( REST, OAuth, OpenID Connect), and microservices-based scalable architectures will ensure a cutting-edge, future-ready TPM platform.
Key Responsibilities
- Technical Leadership: Define and drive architecture and design for TPM, ensuring security, scalability, and performance across front-end and back-end systems.
- Full-Stack Ownership: Lead development using React, NextJS , NestJS , and microservices architectures with MySQL and MSSQL databases.
- Cloud Expertise & Migration: Strategize and execute Azure-to-AWS cloud migration, leveraging deep expertise in AWS services (ECS, Lambda, S3, API Gateway, RDS, EventBridge , SQS, IAM, CDK, etc) with Infrastructure as Code ( IaC ).
- Legacy System Modernization: Work confidently with legacy technologies to plan and execute migration to modern stacks.
- AI & Innovation: Lead POCs and implementation of AI-driven solutions, including LLMs, RAG architectures, and intelligent agent-based workflows.
- Platform Integrations: Ensure seamless integration with Diligent One platforms using RES T and Event Driven Architectures
- Collaboration & Communication: Create technical documentation, architecture diagrams, and design illustrations while driving discussions with cross-functional stakeholders.
- Hands-on Development & Mentorship: Be deeply involved in hands-on coding, mentor engineers, and drive technical excellence.
