Description

We are seeking an experienced Full Stack Developer to join our team. The ideal candidate will design, develop, and maintain end-to-end applications spanning modern front-end frameworks, robust middle-tier services, and scalable cloud-native data solutions. This role emphasizes AI-assisted development practices and hands-on experience building solutions powered by Large Language Models (LLMs).

Key Responsibilities

· Design, develop, and maintain full stack applications from UI through middle tier to data layer

· Build responsive, accessible front-end interfaces using Angular or Vue.js

· Develop RESTful APIs and microservices using Java (Spring Boot) and Python-based frameworks (FastAPI, Flask, Django)

· Design and manage relational and NoSQL data stores including PostgreSQL and document databases (e.g., Amazon DocumentDB, MongoDB)

· Architect and deploy applications on AWS using services such as Lambda, ECS, S3, API Gateway, CloudFormation, and CDK

· Leverage AI-powered coding tools (Amazon Q Developer, Kiro) to accelerate development workflows

· Build and integrate LLM-powered features using AWS Bedrock or similar platforms

· Participate in large-scale document analysis and intelligent data extraction initiatives

· Collaborate with cross-functional teams in Agile/Scrum ceremonies

· Design and maintain end-to-end automated test suites using frameworks such as Selenium, Cypress, or Playwright

· Identify and resolve performance bottlenecks across the full stack including query optimization, API response tuning, front-end rendering, and JVM/Python profiling

· Write unit and integration tests, conduct code reviews, and uphold engineering best practices

· Mentor and guide junior developers through code reviews, pair programming, and knowledge-sharing sessions

Required Qualifications

· 7+ years of professional full stack development experience

· Strong proficiency in Java (Spring Boot, Spring MVC) and Python (FastAPI, Flask, or Django)

· Hands-on experience with Angular or Vue.js for front-end development

· Solid experience with PostgreSQL and document databases (Amazon DocumentDB, MongoDB, or similar)

· Demonstrated experience with AWS cloud services (EC2, Lambda, S3, ECS/EKS, RDS, IAM, CloudWatch)

· Experience using AI-assisted development tools such as Amazon Q Developer or Kiro for code generation, refactoring, and productivity

· Practical experience building applications that integrate Large Language Models (LLMs), preferably using AWS Bedrock

· Familiarity with CI/CD pipelines, containerization (Docker), and infrastructure-as-code

· Experience with end-to-end test automation frameworks (Selenium, Cypress, Playwright, or similar)

· Proven ability to performance tune applications including database query optimization, API latency reduction, front-end profiling, and load testing

· Strong understanding of RESTful API design, microservices architecture, and secure coding practices

· Excellent problem-solving, communication, and collaboration skills

Preferred Qualifications

· Experience with large document analysis, intelligent document processing, or text extraction at scale (e.g., Amazon Textract, custom NLP pipelines)

· Familiarity with Retrieval-Augmented Generation (RAG) patterns and vector databases

· AWS certifications (Solutions Architect, Developer Associate, or similar)

· Experience in the financial services or regulatory technology domain

· Knowledge of prompt engineering and LLM fine-tuning techniques

· Experience with Terraform or AWS CDK for infrastructure management

Education
