Mixmax is the hub for all your business communications. We integrate with your company's existing toolchain - email, calendar, chat, CRM, and more - to bring all information into one place. This means we're syncing, storing, & indexing hundreds of millions of events a day into our system, and then building blazing fast APIs and rich integrations to delight users. Additionally, we have an extensive Developer API that powers entire third party products.

We're looking to hire our first Security Engineer to lay the foundation for all aspects of Mixmax’s application security/platform security from end to end. You’ll be a key communicator, working both cross-functionally in our San Francisco office and across our distributed organization.

As a Security Engineer, you will Design, develop, troubleshoot and debug databases, applications, tools, networks, etc.

As a member of the Platform Guild, you will take an active role in the definition and evolution of standard security practices and procedures. You’ll help start a team specifically focused on ensuring the company runs using forward-focused security mythology and practices. This means being a member of a team that values continuous and collective learning, culture over process, data-driven development and always asking tons of questions. We actively blog about our work, contribute to open source, sponsor Open Collectives, and host/present at meetups - we actively encourage you to do the same and under your own name.


You will immerse yourself in all aspects of security. You are looking for an opportunity that will try your technical skills and challenge your creativity. You are ready to face a wide range of security questions, many of which have not been considered before.

Production servers, networks, endpoint devices, and data are safe in your hands. You are a subject matter expert who wants to implement tactical solutions and contribute to the bigger picture.
