Senior Product Engineer (Backend)

Plain is at the forefront of revolutionizing B2B customer support, trusted by innovative companies like Cursor, Raycast, and Granola. The platform unifies customer interactions and enhances team collaboration with AI capabilities. As a Senior Product Engineer (Backend), you'll join a dynamic Series A startup where engineering goes beyond typical development work - it's about end-to-end problem-solving and product ownership.

You'll be integral to shaping both technical architecture and product roadmap, working across various teams including Core Product, Insights, AI Agents, and Developer Infrastructure. The role offers unique opportunities to tackle complex challenges in data modeling, high-performance reporting, and building scalable systems. You'll contribute to creating not just a product, but a platform that's excellent to build upon.

The ideal candidate thrives in early-stage environments, balancing rapid iteration with thoughtful architecture decisions. You'll work in a remote-first culture that values impact and customer success over code perfection. While the role demands high technical capability in distributed systems and backend architecture, it equally emphasizes product thinking and customer understanding.

This position offers competitive compensation (£75K – £130K plus equity) and the chance to shape the future of customer support technology. You'll be working with a team that's focused on practical solutions rather than chasing the latest tech trends. The role is perfect for senior engineers who want to make a significant impact in a growing company while maintaining their focus on hands-on development rather than management.

If you're passionate about building scalable backend systems, enjoy the challenges of early-stage products, and want to work on technology that's transforming how businesses connect with their customers, this role at Plain offers an exciting opportunity to make your mark.
