Software Engineer - Mobile



Software Engineering
Posted on Tuesday, January 10, 2023

Padlet is building software for a good education. A good education is one that inspires curiosity, creativity, and community. Our software enables that through visual content creation and collaboration in millions of classrooms worldwide.

For a majority of the world, the mobile device is their first computer. For many it’s their only computer. We are looking for Mobile Engineers to improve our mobile apps so we can improve the lives of a billion people.


  • Building new features for our iOS and/or Android apps. E.g. a voice recorder with audio effects.

  • Making apps faster and more reliable. E.g. making network calls more resistant to spotty internet connections.

  • Improving how we work. E.g. improving our internationalization pipelines we use to translate our app into 40+ languages.


  • At some point in your life, someone has told you: “you write good code.”

  • You know how to copy-paste code from Stack Overflow.

  • Bonus: you have a good sense of humor.

About Padlet

  • Vision: Every child in the world will grow up with Mickey Mouse and Padlet.

  • Product: We are making the default way of collecting and sharing thoughts on the Internet. People love the product.

  • Impact: We have over 50 million active users making Padlet one of the most used apps on the planet. Our goal is to be THE the most used app on the planet.

  • Money: We are venture backed AND profitable. We are built to last one hundred years.

  • Badassery: We are 36 people (plus a baby crane that we've adopted but it doesn't really do much). That's over a million active users per employee. Some badass people work here.

Tech stack

  • Mobile apps: React Native (with Swift and Java where necessary.)

  • Backend: Ruby (Rails), Typescript, Elixir (Phoenix), and Python.

  • Web: VueJS, Tailwind.

  • Storage: Postgres, Redis, Elasticsearch, Firestore, and Snowflake.

Joys of engineering at Padlet

  • We have very few meetings. We value keeping you in flow.

  • A lot of people use Padlet. We have to solve interesting concurrency problems.

  • Our users are in over 200 countries, using all kinds of devices and connections, and speaking over 40 languages. We have to solve interesting internationalization problems.

  • We process a lot of data real fast. We have to solve interesting scale problems.

  • We try to solve problems creatively instead of just throwing money at them. We are engineers! We thrive in constraints, not in the absence of them.

  • We ship often.

  • We value beautiful code.

Sorrows of engineering at Padlet

  • We grew pretty fast last year and our processes are still catching up. E.g. we don't have 100% code coverage yet. Our deployment process isn't as painless as it could be. This sometimes leads to spending time on things that aren't the most fun. We’re working on it!

  • Our project management process could be better. This sometimes leads to re-speccing in the middle of development, getting in the way of programming flow. We’re working on it!

Some people you'd be working with

  • Linh Nguyen: At any given point, no one really knows where Linh is. We learn of his existence through pull requests and code reviews. Frontend maestro.

  • Brian Koh: Only human we know who has impulsive urges to exercise. When he does, he doesn't care about outfits. We've seen him running in boots, tight jeans, and leather jackets. Exceptional engineer and even better mentor.


  • Top tier medical insurance for you and your family.

  • Good stock options.

  • Catered lunches and dinners.

  • 20 vacation days. Plus sickness and bereavement days for when life happens.

  • All the gadgetry you need, including a new phone every year.

Special time to join

Because we're small, there's a lot of energy. And because we have tremendous traction, your first commit touches millions. This combination is rare and quite satisfying.
