  • Integrate backend services with databases, messaging systems, and internal JPMC platforms.
  • Optimize application performance, reliability, and security in alignment with enterprise standards.

Frontend Development (React)

  • Develop responsive, high‑performance UI components using React, Redux, TypeScript, and modern JavaScript.
  • Collaborate with UX teams to translate wireframes and design specifications into functional interfaces.
  • Ensure seamless integration between frontend and backend services.
  • Implement reusable components, state management patterns, and UI performance optimizations.

Cloud, DevOps & CI/CD

  • Work with cloud‑native environments (AWS, Google Cloud Platform, or internal JPMC cloud platforms).
  • Contribute to CI/CD pipelines using tools such as Jenkins, GitLab, or Azure DevOps.
  • Support containerization and deployment using Docker and Kubernetes.
  • Ensure code quality through automated testing, linting, and continuous integration.

Collaboration & Delivery

  • Partner with cross‑functional teams including Product, QA, DevOps, and Architecture.
  • Participate in Agile ceremonies, sprint planning, and technical design discussions.
  • Troubleshoot production issues and support ongoing enhancements.
  • Follow JPMC’s engineering standards, security guidelines, and compliance requirements.

Required Skills & Qualifications

  • 12+ years of professional software development experience.
  • Strong hands‑on experience with Python (Flask, FastAPI, Django).
  • Advanced proficiency in React, JavaScript/TypeScript, Redux, and modern UI frameworks.
  • Experience building and consuming REST APIs and microservices.
  • Solid understanding of relational and NoSQL databases (PostgreSQL, MySQL, MongoDB).
  • Experience with Git, CI/CD pipelines, and cloud environments.
  • Strong debugging, problem‑solving, and performance optimization skills.
  • Excellent communication skills and ability to work in a fast‑paced financial environment.
