MailChimp makes powerful marketing products that people love to use, and our engineers make it all possible. We hire world-class talent, give them the resources and support they need, then turn them loose to do great work.

Small teams, big impact

Our engineers are empowered to be nimble and autonomous. They solve tough problems every day, and no 2 days are ever the same.

MailChimp has millions of users with more than 20 billion subscriptions, and 14,000 new accounts are created every day. Our apps run off thousands of servers and we handle 1.2 million queries per second in our primary database layer. Our API, now in v3.0, gets 160 million requests every day. At its peak, our new Data Pipeline sees up to 1 million events per second. We helped send 246,148,661,219 emails in 2016.

We give markets production-ready software designed to help them grow. We succeed through togetherness, momentum, and pragmatism.

A place to be yourself

Our engineers have come to MailChimp from many different paths, and they fill unique roles all over the company. We support the next generation of engineers with lots of opportunities for professional development, including internal apprenticeships and tuition reimbursement for completing or continuing education.

Grow your own way

There’s not just one kind of engineer at MailChimp. Some are specialists, others are generalists, and there are always opportunities to grow. With our 2 flexible ladders (technical and management), that growth can be vertical, horizontal, or even diagonal. Our engineers follow their own paths, not rigid organizational structures.
