  • Mentor other developers in UI best practices, being a role model for their adoption across the team.

  • Opportunity to take forward older UIs that use jQuery, HTML templates, etc.
  • Act as an escalation point for the Infrastructure and Operations team to resolve production and operational issues within your area of expertise.
  • Collaborate with team members to address follow ups from production and operational issues.

Skills & Experience

  • At least 4 years of professional programming experience, ideally in a front office trading environment.
