Who we are
Our mission at Nylas is to turn communication into inspiration and insight. We empower over 100,000 developers and over 900 companies all over the world to access, parse, and gain insights from communications data to provide better experiences for their customers and users, all while providing top tier security and compliance. To achieve this vision, we’ve raised over $175M from Tiger Global, 8VC, ScaleUp, Spark Capital, Slack, and more.
We have a huge market (every company that builds software) and a massive opportunity (the world runs on communication and data). By continuing to hire exceptional people from all different backgrounds and perspectives, we have the opportunity to make Nylas one of the biggest, most successful and equitable technology companies in the world.
Why Nylas
Nylas is an advocate for the well-being of our employees. We trust our employees and give them the autonomy to achieve their goals without focusing on when, where, and how they get there. We are a flexibility first workplace, but if Nylanauts want to work from an office, we have hubs in San Francisco, Denver, New York City, Toronto, and London.
We are also strong supporters of internal and cross-team mobility and growth. We want Nylas to be a place where anyone can be supported to grow, learn, and become the best at what they do. We’ve been named a top Startup for career growth and development by Forbes, Great Places to Work, and Comparably!
From our CTO + Co-Founder, Christine Spang:
“We have a number of folks on the team who started as an individual contributor and became staff level or leaders in their area. I personally love seeing people reach their full potential and become successful at Nylas.”

About the role

Nylas is currently operating at extreme scale with sharded MySQL clusters fronted by ProxySQL and managed with Terraform and Ansible. You will be responsible for the administration, scaling and maintenance of these MySQL clusters. You will also pair with our AI/ML team on getting the data they need to train new models.
