Senior DevOps Engineer

Job description

Chatterbug is building the internet’s best way to learn a language by empowering those who speak them: Humans! Humans build our curriculum, teach our students how to speak in one-on-one lessons, and now we are looking for a few more humans to join us in making Chatterbug the best it can be.

About the job

Speed and accountability are two values our engineering team cares about deeply. Chatterbug is growing and looking for an engineer who prides themselves in taking ownership of the infrastructure that helps us scale not only with our user base but our team as well. Given that we ingest, transform and serve a large amount of video, our infrastructure comes with a unique set of challenges which are difficult and rare, yet rewarding to solve.


As we introduce new languages, enterprise offerings, mobile applications and explore strategic integrations and partnerships, we anticipate the complexity and scale of our systems to increase over the next year. As the first devops engineer on the team, you’ll join as an early employee at one of the most exciting times in our company's history.


The heart of our service is a Rails 5.2 application "monolith", and not a disjointed series of services. On the backend side, we use many tools, including:


  • PostgreSQL 10 via Heroku

  • Fastly and Netlify for static content serving and caching

  • TokBox, Twilio and OpenVidu for video/WebRTC services

  • Travis CI for running our Ruby and JS test suites

  • Sauce Labs combined with Rails' system testing for real browser tests

  • AWS services including: S3, Polly, AWS ML

  • Cluvio and Mode to help analyze and present data to our business and marketing teams

As a Senior DevOps Engineer, you’ll architect and manage the infrastructure behind Chatterbug to help make our services run smoothly. On a given day you could be tracing a Live Lesson's logs and graphs to determine why a tutor's connection suddenly went haywire, building a new piece of infrastructure to allow us to support more students in the future, and more. 


About you

You’re a multi-talented, experienced engineer who wants to join our team building our language-learning product and infrastructure. You’ll be part of a small development team and will have the opportunity to own major components of our systems. You’re an active learner whose passions may include learning languages. (If you know a language other than English please tell us!)


About us

Although we are a small company, we have a big product. We are an experienced team with backgrounds at GitHub and other major tech companies with funding from top investors in Silicon Valley and Europe. Our team works extremely reasonable hours and we have a strong commitment to work-life balance.


Beyond language learning, we’re on a bigger mission to help make lots of jobs for people who only need one skill: how to speak their native language. We currently teach German and Spanish and French to English speakers, as well as English to Spanish speakers. We have an international team and an international product, and we’re proud of it.


Curious about how the company operates? Here’s a quick overview:


  • Remote flexibility. Our largest office is in Berlin with ~24 people, but our team is encouraged to travel and work from home when needed. Because of the vast time zone spread (9 hours now!), we focus on asynchronous communication when possible, via Slack and Basecamp.

  • Work/life balance matters. We work a full day then go home, and please set up your Do Not Disturb. That Slack message can wait, can’t it? We think so too.

  • Face time brings us together. Since we’re split up over the world, we put a lot of value on our weekly in-video “Chattermeet” all-hands meetings. We share what’s happening in the company, our product, our curriculum, and occasionally some tidbits about our lives too.

  • Learning first. We have monthly breakfast meetings at our Berlin office to teach about our systems and we encourage our employees to network and be continual learners at professional events.

  • Pitch us. Ideas for our company and our product can come from all levels or layers of the organization—you just need to write it up or propose it!
