Description

We are seeking a Senior Frontend Engineer to design, develop, and maintain enterprise-scale digital banking applications supporting small and mid-sized business clients.

This role is primarily focused on Angular-based frontend development, with exposure to ReactJS, in a complex and regulated banking environment. The ideal candidate has strong experience working within established enterprise applications, integrating with backend services, and owning features from development through production support.

Key Responsibilities:

  • Design, develop, and maintain Angular-based single-page applications supporting digital banking capabilities.
  • Build reusable and maintainable frontend components using Angular, TypeScript, JavaScript, HTML5, and CSS3.
  • Enhance and modernize existing frontend applications while maintaining backward compatibility and production stability.
  • Develop role- and entitlement-driven user experiences, including conditional rendering, feature gating, and unauthorized-user handling.
  • Integrate frontend applications with RESTful APIs and backend services using JSON-based contracts.
  • Partner with backend engineering teams to ensure API contracts, error handling, and data models support reliable frontend experiences.
  • Utilize Node.js for frontend-adjacent and backend-for-frontend functionality when needed.
  • Develop and maintain unit tests using Jasmine, Karma, or similar frameworks.
  • Troubleshoot defects, resolve production issues, and support application performance improvements.
  • Support release activities including build generation, validation, and QA coordination.
  • Participate in Agile ceremonies and collaborate with Product, UX, QA, Security, and Platform teams.
  • Conduct code reviews and provide technical guidance to junior engineers.

Required Qualifications:

  • 5+ years of frontend development experience in enterprise environments.
  • Strong hands-on experience with Angular, including experience across AngularJS and modern Angular versions.
  • Advanced knowledge of TypeScript and JavaScript.
  • Strong experience with HTML5, CSS3, Bootstrap, and Flexbox.
  • Experience integrating frontend applications with REST APIs.
  • Working knowledge of Node.js, npm, and nvm.
  • Experience with modular or micro-frontend architectures, shared UI libraries, or independently deployed frontend modules.
  • Familiarity with build tools such as Webpack, Gulp, Grunt, Vite, Rollup, or Parcel.
  • Experience with frontend testing frameworks such as Jasmine or Karma.
  • Proficiency with Git and Agile development practices.
  • Experience working in financial services, digital banking, payments, or another regulated environment.

Preferred Qualifications:

  • Experience with payments, transfers, bill pay, or entitlement-based banking workflows.
  • ReactJS development experience.
  • Exposure to hybrid or web-based mobile applications.
  • Experience supporting or generating mobile builds.
  • Experience mentoring engineers or acting as a technical lead.
  • Understanding of frontend security concepts including Content Security Policy (CSP), authentication, authorization, entitlement management, and secure handling of client data.
  • What Success Looks Like
  • Ability to quickly contribute within established Angular and ReactJS codebases.
  • Strong ownership of features from requirements and development through testing, release, and production support.
  • Ability to modernize existing applications without negatively impacting production stability.
  • Strong understanding of security and authorization requirements within digital banking applications.
  • Consistent delivery of maintainable, high-quality code while balancing speed, reliability, and business needs
