JavaScript (Programming Language) TypeScript ReactJS Legacy Systems

Job description

The client isn’t expecting someone who’s spent the last five years writing Objective-J. They’re looking for a strong React engineer who is comfortable understanding an existing Objective-J/Cappuccino codebase, making changes where required, and helping drive the migration to React over time.

Requirements

  • Strong commercial experience with React
  • Excellent JavaScript / TypeScript skills
  • Experience working on large enterprise or legacy applications
  • Experience modernising or migrating legacy systems
  • Exposure to Objective-J, Cappuccino or similar legacy frontend technologies

Benefits & conditions

Contract Outside IR35 £400 per day Fully Remote Initial 6 Months, * £400 per day
  • Outside IR35
  • Fully remote
  • Initial 6-month contract
  • Strong potential for extension

If you’ve worked with React on enterprise applications and have any exposure to Objective-J/Cappuccino - even if it was earlier in your career- I’d be really keen to speak with you.
