SG2 Recruiting is a recruiting partner for the Greymatter.io team looking for cleared and clearable API/Platform software engineers. The Greymatter.io team builds infrastructure intelligence solutions for managing, governing, and operating customer enterprise software. We are multi-context, high-velocity, and use state-of-the-art technology. We focus on automation, solving complex challenges across multiple customers, and ensuring smooth and expedient services to users.

We support substantial multi-cloud, hybrid, and Kubernetes workloads running large-scale cloud-native systems that communicate using our Grey Matter service mesh platform. Working at this scale gives our engineers the chance to develop their existing cloud skills to a whole new level of challenges, tools, and strategies.


Our team helps organizations automate network configurations, discover services, and enable secure connectivity across any cloud. Our customers are operators, infrastructure engineers, and software developers that encounter novel performance, security, scaling, and usability challenges that we help them solve. Some examples of the functionality you'll be working on will include proxy integrations, Envoy's xDS APIs, certificate management for mutual TLS connectivity, and security through service-oriented patterns. You'll actively contribute to the service mesh ecosystem, follow new developments in emerging technology, look for opportunities to differentiate our product from the competition, and rethink product architecture to meet new global scale and organizational demands.
