Job Description

As a QA SDET intern, you'll do everything that a full time Optimizely SDET engineer does! You'll collaborate with engineers, designers, & product managers; build software automation tools to help detect bugs; read & write design docs; & attend standups & team lunches. And you'll also get to participate in our summer Hackathon.

You'll also get 1:1 mentorship experience with an Optimizely engineer who will make sure that you thrive at Optimizely. Additionally, you will have regular coaching sessions with your manager.

Your summer will be focused on building & contributing to Optimizely's frontend & backend automation frameworks; while in parallel learning software QA principles & applying them.

What's it like for interns who work at Optimizely?

We treat our interns like full-time employees: your opinions & ideas matter here & can shape the way we build things. Interns have worked on a number of impactful features & products that have made it to the hands of our customers during their summer.

More than shipping code, though, we host offsites for the intern class; in the past, we've been to Giants games, escape rooms, & Benihana.

What we're looking for in interns:

  • You're passionate, curious, and/or skilled in web application development.

  • You have demonstrated skill & enthusiasm for learning about & applying new technologies & open source packages when appropriate.

  • You have strong interpersonal communication skills & the ability to work well in a diverse, team-focused environment with other engineers, product managers, designers, & partners outside of Engineering.

  • You have some experience with at least one web programming language, like Ruby, Python or Java

  • You have some basic familiarity with HTML, CSS & Javascript.

  • You want to write clean, modular & testable code.

  • Your experience is less important than your enthusiasm for learning & collaboration. For example, it helps to know JavaScript, but we've had frontend interns who arrived here knowing only Java :)

Bonus Points, but not necessary:

  • You're familiar with a backend web stack. We use Python web frameworks like Pyramid & Django, & ship our builds via Docker on AWS & on Google App Engine.

  • You are proficient in any of the following: jQuery, CSS, HTML5, AJAX, or React. We use VueJS, NuclearJS, & React on our frontend.

  • You have an understanding of closures, prototypal inheritance, DOM manipulation, HTTP, web security & cross browser compatibility challenges.
