About the Opportunity

This is an exciting opportunity to join a collaborative development team driving a large-scale digital modernization initiative. In this hands-on role, you will contribute to a critical platform migration while building modern, high-performing applications that support meaningful user experiences at scale.

Working alongside engineers, product managers, and designers, you will help shape both backend and frontend solutions in a fast-paced, delivery-focused environment. This role is well suited to someone who enjoys solving complex problems, mentoring others, and seeing their work make a tangible impact within a large, mission-driven organization.

What’s In It for You

You’ll be part of a team that values collaboration, technical excellence, and continuous improvement. This environment encourages knowledge sharing, thoughtful design, and building solutions that last.

You’ll gain exposure to a large digital transformation initiative, working with modern frameworks, cloud platforms, and experienced technical leaders, while having the opportunity to influence architecture and development best practices.

Your Responsibilities

  • You’ll contribute to the migration of applications into a Django (Python) Backend-for-Frontend architecture.

  • In this role, you’ll design and build responsive, user-friendly frontend components using React, JavaScript, HTML5, and CSS3.

  • You’ll build, optimize, and maintain APIs while strengthening backend infrastructure.

  • You’ll refactor existing code to improve maintainability, scalability, and long-term performance.

  • You’ll ensure accessibility, responsiveness, and cross-browser compatibility across all frontend solutions.

  • You’ll conduct automated testing across backend and frontend systems to support high-quality releases.

  • You’ll mentor team members, participate in code reviews, and contribute to technical documentation.

Skills and Qualifications

  • 10+ years of full-stack development experience across backend and frontend systems.

  • Advanced expertise with Django, Python, and relational databases such as PostgreSQL or MySQL.

  • Strong frontend development experience with React and modern JavaScript frameworks.

  • Proven experience building scalable APIs and working with cloud platforms such as AWS, Azure, or GCP.

  • Hands-on experience with testing frameworks such as Jest, Cypress, or Mocha.

  • Strong communication skills and the ability to collaborate effectively across technical and non-technical teams.

  • Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.
