Location : Remote (India-based candidates preferred)
Employment : Full-time (Hired through VS Technology , working on ServeFirst product)
ServeFirst is a scrappy, well-funded AI startup (recently closed a £4.5m seed round ) that’s redefining how businesses understand their customers. We transform raw customer feedback into real-time insights for companies that care deeply about CX.
Our 2025 roadmap is ambitious :
- Break apart our Node.js monolith into scalable microservices
- Double our AI-driven workflows
- Harden our infra to handle 100× traffic growth
- Maintain a culture where everyone ships, everyone is on-call, bureaucracy is nil, and velocity is high
This is a chance to join early, own core architecture decisions, and scale AI-first systems in production
