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. 
• We are looking for folks willing to jump into our most complex modules and solve our trickiest problems.
• 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.

What We Need

• Expertise in modern JavaScript (ES6), TypeScript, NodeJS
• Experience with building and deploying applications in public clouds like AWS, GCP, and Azure
• A strong, hands-on technical track record of delivering public-facing APIs (REST, GraphQL)
• Extensive experience working with scalable cloud services, particularly with event-based asynchronous programming frameworks like Node.js or distributed queues
• Deep understanding of distributed systems concepts like caching, traceability, security, databases, sharding, and regional deployments
• Proven ability to be self-directed and operate effectively in a fast-paced and high-energy environment
• Nice to have experience in Enterprise-class AuthZ/AuthN (SSO, OAuth2, OpenIDConnect and etc.)
