Sr. Front End Engineer - Twilio Flex


Because you belong at Twilio

The Who, What, Where and Why


Twilio is looking for a Senior Front End Engineer skilled at building rich, high fidelity front-end web experiences.

You have experience building fast-rendering reusable and extendable components using HTML, CSS and modern JavaScript Frameworks such as React.

You bring experience with build patterns common to web technology stacks, you love shipping amazing products and you sweat the little things around user experience.

You communicate well out loud, on paper and in code. You love to make an impact and thrive in small, collaborative, energetic teams.


As a Senior Front End Engineer you will be part of a cross functional team that designs, builds and operates Twilio Flex - the first fully programmable cloud contact center platform.

Twilio Flex delivers an instantly deployable, cloud-based platform that allows businesses to programmatically customize every element of their contact center experience -- from the core infrastructure to the user interfaces.

You will own and create front end experiences, from individual components to entire web applications and frameworks collaborating with Designers, Product Managers and Engineers.

Our React based UI framework powers user experiences for agents, supervisors, administrators and end users of our customers on their websites for some of the largest contact centers in the world.

You enjoy getting the MVP out the door, and you know that great user experience takes ongoing investment, refinement and polish.

With the launch of Flex, Twilio introduces a new type of platform for applications which has the potential to disrupt traditional monolithic application vendors in the same way API platforms disrupted traditional infrastructure services for communications, compute and payments.

Occasional travel to the San Francisco based headquarters is something that you should be able to accommodate as well. What you will also get to experience is a company that believes in small teams for maximum impact; that strives to balance work and home life, we know this is a marathon not a sprint; that builds an inclusive culture where we want all of our people to be comfortable and thrive.  We seek out people who live by our values, who are challenged by problems, empower others to thrive, people who can draw the owl and not be beholden to one playbook.
