Job Description

Build and shape the next generation of support tooling. 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, Vercel, 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

  • Build across the stack: frontend interfaces, backend logic, and everything in between
  • Ship high impact features that are fast, reliable, and delightful
  • Contribute to product and technical direction, working closely with design, engineering, and founders
  • Collaborate tightly with customers to understand their problems and solve them elegantly
  • Help shape a fast moving, product centric engineering culture

Requirements

  • Have shipped features end-to-end in fast paced environments
  • Take initiative and show strong agency
  • Are impact driven and motivated by seeing customers succeed
  • Want to work closely with customers and shape product decisions
  • Care deeply about craft and love building products that feel simple, powerful, and polished
  • Want to not only do great work in a fast paced team, but also have a voice to level up how Plain as a company works

What we offer

  • Competitive salary, and a generous option grant on employee-friendly terms
  • Two global offsites per year in great locations, plus team-based offsites throughout the year
  • 35 days annual leave - including public holidays - to take as you wish
  • 4 extra days off a year, a chance for all of us to recharge at the beginning of a quarter
  • Private Health Insurance: 100% employee coverage, dental and vision, access to out-of-network care. Also included: life insurance
  • $100 Monthly Wellness Credit
  • $1000 WFH stipend
  • Retirement Planning: UK and Ireland: Employer matching up to 5%. USA: Contribute to your 401k pre-tax, with no employer match
