What You’ll Be Doing 

• Build a secure, highly available cloud system that reliably ingests, quotes, and tracks millions of parts as they are manufactured around the world. 
• Because we handle a significant amount of pre-production intellectual property, it is critical that we protect our customer’s data even as we move it across the globe.
• Set the standard for building high-quality software. 
• This is 100% a hands-on role where you will tackle complex problems, design clean solutions, write clear code (including tests!), and lead by example.

• Promote best practices for working together to frequently deliver changes to production. Software development is a team sport, and we look to all our engineers to help one another achieve team goals, ensure uptime for our services, and give/receive feedback on how we can improve individually and collectively.
• Tackling a wide range of technical systems and challenges. 
• We’re growing fast as a product and business, so the type of work will be dynamic and diverse. 
• Examples of things you may work on include implementing token-based authorization and access control, developing algorithms to optimize job matching to manufacturing partners, building graceful failover between two third-party shipping services, and optimizing database queries to scale our backend services.
