Senior Engineering Manager - Reliability Engineering


Because you belong at Twilio

The Who, What, Where and Why


We are looking for a talented and experienced engineering leader who is passionate about building software platforms for other Twilio engineering teams, delivering force-multiplying software solutions that keep Twilio shipping products with quality and velocity. You are the right fit for this role if you have a track record of recruiting, building, and retaining high-performing engineering teams in execution of your goals. You are an API first engineering leader who understands the power of platforms.  You are passionate about enabling other developers through the software experiences you create. You have the ability to balance long-term objectives with urgent short-term needs, and with your sound decision making and managerial creativity, you can successfully lead teams through very challenging situations. You’ll bring your deep experience with reliabile software engineering, particularly with regards to testing, along with agile development practices to the table. You are passionate about testing and operational excellence and know how to build an engineering organization that delivers it. You are able to think at scale, define, and meet stringent availability and performance SLAs while ensuring quality and resiliency challenges across our diverse product and tech stacks are addressed.


A successful day means you have worked with your team providing engineering leadership and ensuring your resources are solving the most critical reliability engineering problems.   You focus on delivering the highest quality of services, and you support your team as they push production code that impacts hundreds of Twilio developers. You also spent time with customer engineering managers and developers to create and deliver critical new products and/or features that empower them to introduce change with quality and speed.  Before the end of the day, you make sure to connect with your team, both onsite and remote, to ensure they are delivering on engineering and operational excellence.


The Reliability Engineering team enables Twilio builders to create unique experiences that will fuel the future of communications by delivering testing capabilities that allow teams to successfully prove the reliability and functionality of their software in a multitude of ways - from integrations tests to load testing to failure injection.  The Reliability Engineering team develops and operates the worldwide infrastructure for a comprehensive and integrated software qualification experience. You are not centralized quality assurance or quality engineering. You develop software that eliminates the need for specialized testers.

Twilio is a company that empowers the world’s developers with modern communication in order to build better applications. The Reliability Engineering team plays a vital role in building out key products and capabilities that allow our developers to meet their commitment of delivering compelling software solutions quickly and with confidence. We would love for you to help us build this.

Twilio is committed to your growth, your learning, your development and your entire employee experience. We only win when our employees succeed and we're dedicated to helping you develop your strengths. We invest in weeks dedicated to tackling hard problems and creating your own ideas. We have a cultural foundation built on diversity, inclusion and innovation and we want you and your ideas to thrive at Twilio. Come join us.


This position will be located in our beautiful office at 375 Beale St in San Francisco, CA. You should expect the normal perks: catered meals, snacks, game room, ergonomic desks, etc. 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.   About us: More than 2 million developers around the world have used Twilio to unlock the magic of communications to improve any human experience.
