Senior Back End Engineer UK Based
ABOUT KYRA
Kyra is an enterprise influencer marketing platform working with brands like SharkNinja, Coach, H&M, Ray-Ban, and Converse. Our platform manages the full lifecycle — creator discovery, campaign management, content review, payments, analytics, and AI-powered intelligence across TikTok, Instagram, and YouTube.
THE ROLE
We’re looking for a senior backend engineer with sharp product judgement. You’ll work alongside our engineering lead on a platform that processes millions of creator data points, runs real-time analytics, and powers AI-driven workflows.

WHAT YOU’LL ACTUALLY DO

• Build features that span our main transactional backend and a separate analytics backend running heavy queries over creator data.
• Write services that integrate with TikTok, Instagram, and YouTube APIs.
• Work with queue workers for background job processing (media analysis, outreach, data syncing).
• Deploy your own services to our cloud infrastructure, write the migrations, watch them go out safely.
• Investigate production issues when they touch your code — trace through the observability stack to find the cause.
REQUIRED — NON-NEGOTIABLE
• 6+ years backend development with Node.js and TypeScript in production.
• Product mindset — you’ve shipped features where the brief was a paragraph, not a ticket. You ask why before how, make calls when requirements are vague, and iterate after release. You’ve sat across from non-engineers and left with a sha...
