About Connect-AI
Senior Software Engineer
Remote – UK / Europe (GMT to GMT+2)Full-time | Early-stage VC-backed startup
up to £120,000 P/A
We’re hiring a Senior Backend Engineer to join a fast-growing, VC-backed startup building developer-facing AI infrastructure.
This is not a typical “CRUD API” role.
You’ll be building and owning the backend foundations behind AI-powered systems used by real users in production — APIs, distributed services, async workflows, data pipelines, and infrastructure that needs to scale reliably.
What You’ll Work On
Designing and building production-grade APIs used by external developers
Owning backend services that support AI agents and large data workflows
Handling async processing, queues, caching, and traffic spikes
Building systems that process complex or heavy data payloads
Collaborating closely with Product & Design in a small, high-autonomy team
Making pragmatic architectural decisions in a fast-moving environment
What We’re Looking For
Strong experience building and scaling backend systems in production
Deep knowledge of Node.js / TypeScript
Experience with:
Distributed systems
Async workflows
Event-driven architecture
Caching strategies
Experience working in VC-backed startups or small product teams
Comfortable operating with high autonomy and minimal process
Strong communication skills in async, remote environments
Nice to Have
Experience building AI-powered backend systems (LLMs, RAG, agents)
Experience designing APIs used by other engineers
Exposure to self-hosted or enterprise deployment models
Not the Right Fit If
Your experience is primarily frontend-focused
Most of your background is ecommerce, digital agencies, or enterprise-only environments
You prefer highly structured orgs with strict roadmaps and layers of management
What You’ll Get
Competitive salary + meaningful equity
35 days holiday (including local holidays)
Remote-first culture
High ownership and real impact
Direct collaboration with founders
Opportunity to shape backend architecture from the ground up
