  • Collaborate with product, design, and client-facing teams to iterate on features and improve user experience.
  • Write and maintain automated tests (unit and UI) to ensure code quality and application stability.
  • Troubleshoot UI issues, optimize performance, and proactively identify UX or technical improvements.
  • Contribute to code reviews, documentation, and engineering best practices across the Vantage Technology team.

  • Proficiency in modern JavaScript/TypeScript and front-end technologies (e.g., React, Angular, or Vue).
  • Experience with front-end frameworks, component libraries, and state management patterns.
  • Working knowledge of backend systems, APIs, and data integration to effectively collaborate across the stack.
  • Familiarity with agile development methodologies and cross-functional product teams.
  • Experience building responsive, data-driven, client-facing applications.
  • Self-starter with a strategic mindset and strong attention to detail.
  • Bachelor's degree in Computer Science, Engineering, or a related field.
  • Preferred: Understanding of financial products or complex data-heavy platforms (structured products a plus).
