About OptiCab
OptiCab is a UK technology company helping taxi and private hire fleets do more with the systems they already have. Rather than replacing dispatch platforms we build on top of them: Chat booking assistants, automated review and email engines, QR venue booking, social media tools and analytics dashboards. Our products help operators win more bookings, run leaner operations and give passengers and drivers a better experience. We're profitable, growing, and investing seriously in engineering to support an expanding product suite.
The role
You'll build and maintain the backend services that power our fleet automation. That means designing and optimising APIs, integrating with third-party dispatch systems, telephony and messaging platforms, and keeping data flows fast, reliable and secure across bookings, calls and analytics.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Day to day you'll write clean, testable JavaScript, work with Node.js services deployed on AWS, troubleshoot production issues, and ship features shaped by real feedback from live fleets. You'll collaborate closely with product and front-end colleagues, contribute to code reviews and documentation, and help refine our architecture and engineering practices as we scale.
