Job Description:

Plain is redefining customer support for the next generation of B2B companies. We’re building the fastest, most powerful platform to help companies move beyond reactive support and build true customer relationships. Some of the world’s most forward-thinking companies - like Cursor, Raycast, and Granola - trust Plain to unify all customer interactions, enable faster team collaboration, and supercharge their workflows with AI. B2B customer support is undergoing a seismic shift. AI is transforming the way companies engage with customers, shifting support from a siloed function to a company-wide effort across Slack, Discord, and any other channel you talk to customers in. The old way - slow, manual, and disconnected - no longer works.

Job Responsibility:

  • Help set product direction. You’ll contribute to both the technical architecture and the roadmap, balancing customer feedback with long-term product health
  • Ship features end to end. You’ll scope, build, and launch product features that directly solve customer problems
  • Shape our backend architecture. You’ll tackle some of our most complex challenges, from data modeling to high-performance reporting, and help set the standard for how we build across the company
  • Create a stellar developer experience. From data pipelines to APIs, you’ll make sure Plain is not only great to use but also great to build on

Requirements:

  • Thrive in early ideation stages, love sharing work-in-progress, and enjoy the balance of making trade-offs in order to ship high impact products
  • Are impact driven and motivated by seeing customers succeed. You measure the quality of your work by the end-experience of users, not the abstractions or cleanliness of the code
  • Have a proven track record working for product-led companies, ideally in B2B SaaS
  • You’re autonomous and able to prioritise your workload. You know when to take a shortcut and when to invest in long-term infrastructure
  • Have experience working with distributed, serverless systems, and have worked on similar web applications with a high quality and performance bar before
  • Are equally at home in architectural conversations as you are in customer conversations
  • Can learn new technologies and paradigms quickly and independently
