About Customer.io

Over 7,500 companies — from scrappy startups to global brands — use our platform to send billions of emails, push notifications, in-app messages, and SMS every day. Customer.io powers automated communication that people actually want to receive. We help teams send smarter, more relevant messages using real-time behavioral data.

About you

You're a systems-minded writer who brings clarity to complexity. You have a sharp eye for detail, a passion for consistency, and the ability to transform technical design decisions into clear, actionable guidance. You're energized by creating documentation that empowers teams, and you understand that great design systems need great content. Whether it's defining when to use a button versus a link, or establishing tone for error messages, you bring precision, empathy, and craft to everything you write.

What you'll do

  • Audit and document 50+ design system components, creating comprehensive guidelines for usage, anatomy, behavior, accessibility, and content.
  • Establish voice, tone, and content standards for component documentation—creating templates and patterns that scale across the system.
  • Collaborate with the Design Systems Lead to prioritize components, understand design decisions, and ensure guidelines reflect real-world usage.
  • Define and document content patterns for common UI scenarios (error states, empty states, CTAs, validation messages, etc.).
  • Create before/after examples that demonstrate best practices and common pitfalls for each component.
  • Work cross-functionally with Product and Engineering to ensure guidelines are practical, implementable, and aligned with how teams actually build.
  • Improve discoverability and organization of design system documentation in Figma and Notion.

What we're looking for

  • 3+ years of UX writing experience, with at least one project involving design systems, component libraries, or technical documentation.
  • Proven ability to write clear, concise guidelines that balance technical accuracy with practical usability.
  • Strong portfolio demonstrating component documentation, UI content, or similar systems-level writing work.
  • Experience with Figma and comfort navigating design files, understanding component structure, and collaborating with designers.
  • Familiarity with accessibility standards (WCAG) and inclusive design principles.
  • Exceptional organizational skills and attention to detail—you're energized by creating order and consistency.
  • Comfort working independently in a remote-first, async-friendly environment with some overlap for collaboration.
  • A pragmatic communicator who asks great questions, gives clear rationale for decisions, and values feedback.

Compensation & Benefits

We believe in transparency. Starting agreement for this role is $60/hr-$70/hr USD (or equivalent in local currency) depending on experience and subject to market rate adjustment.

Our Process

No gotchas, no trick questions - just a clear, human process designed to help both of us make an informed decision.

  1. 30-minute phone call with a Recruiter

  2. 60-minute video call with the Hiring Manager

All final candidates will be asked to complete a background check and employment verifications as part of our pre-employment process.

Customer.io recognizes the stifling impact of systemic injustice on diverse communities. We commit to using our influence to increase inclusion and equity within the tech industry. We strive to build an inclusive team culture, implement bias-free hiring practices, and develop community partnerships to expand our global impact.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
