Staff On-boarding (10%)


We’re on a mission to make the world safer and more productive through open source. To make that happen we first have to create a great place to work–an inclusive, courteous online community where incredibly talented individuals are empowered to do their best work for our customers, with very little in their way. This guide is a summary of our guiding principles. As Mattermost grows, we hope these principles serve each new staff person that joins us. If you are new to Mattermost, welcome! While the goals here are important, it’s your ideas, talent, and energy that will keep Mattermost shining in the years ahead. Thanks for being here. Let’s change the world.

Our handbook defines what it’s like to work at Mattermost, from the high level to specific operating procedures. If you’re new, you’ll start with our onboarding guides.

Our mission is to make the world safer and more productive by developing and delivering secure, open source collaboration software that is trusted, flexible and offers fast time-to-value.

Leadership principles are deliberate choices defining our behavior. When facing complexity, uncertainty, or ambiguity (CUA) we determine our point of view and our actions through the lens of our values:

  • Customer Obsession - Mattermost exists to make customers successful. Every project starts with the customer perspective.

  • Ownership — Own the outcome of your actions. Act on behalf of the company, not just the team. Never say “that’s not my job.”

  • High-Impact — Choose high-impact projects over low-impact projects. Figure out what matters most and focus on those priorities.

  • Insist on High Standards — Have relentless high standards. Continually raise the bar for high-quality products and processes.

  • Self-Awareness — Seek to understand strengths and growth opportunities while being open to criticism. Share critiques constructively and respectfully.

  • Earn Trust — Make decisions based on maximizing the trust of others in your judgment. Be open, self-critical and factual.

Mattermost is an open source, remote-first, communities-centered company based in Palo Alto, California and headquartered on the internet.

Open source means that by default we make our technology, business process and source code available to the public. We develop a small portion as proprietary technology, built upon our open source work, to license for subscription fees that enable more high quality open source work to be produced. Since the start of the Mattermost open source project in 2015, we have used this model to develop effective open source solutions for the world to use. This model is sometimes called Thin Open Core.

Remote-first means that by default our staff works anywhere in the world where a) we have support for quality video calling and b) where we can work in a legally appropriate environment. Mattermost was born in an extraordinary age where organizations can attract, hire and enable remote teams–working from homes, coffee shops and co-working spaces across timezones–to produce better technology and business results in less time than purely office-based teams, while maintaining security and compliance standards.

Remote-first culture flourishes when we share one simple principle: Courtesy. Courtesy means Mattermosters are thoughtful about keeping our communities appropriately informed, following etiquette for discussions, calls and video meetings, and giving and receiving feedback on how to work better together. Courtesy also means we gladly accommodate those who prefer to work out of a dedicated office. We are remote-first, not remote-only.

Communities-centered means we define our success in the context of the success of our communities: users, customers, implementers, resellers, technology partners, contributors, and colleagues. The success of each community is owned by a member of the Mattermost leadership team. The plural definition of “communities” is intended to avoid unconsciously marginalizing downstream stakeholders.

Based in Palo Alto, California and headquartered on the internet means the mailing address for Mattermost, Inc. is in Palo Alto, California, and our headquarters is on the internet, specifically the Mattermost instance at Our online headquarters is where Mattermost staff work with our communities of colleagues, users, partners, customers and contributors, to envision, develop and refine new open source technologies to make the world safer and more productive.
