Overview

This role is responsible for the ongoing design and development of Prism Core, our IoT software platform, a distributed microservices environment based on Node.js. Prism Core runs on Linux servers, typically in a cloud environment like AWS, but can also run in any cloud or on-prem environment that supports Linux. Our shared-tenant platform is designed for five-nines availability, currently processing about 90 million transactions per day, and is growing rapidly. Using Node.js, you will integrate with a variety of supporting services, including databases, distributed caching, message brokers, AI (LLM, ML, and CV), and third-party systems via API integrations. Projects include developing and integrating new technologies into the platform, as well as enhancing existing capabilities around security, performance, and scalability.

Additional responsibilities include working with applications and front-end developers to solve specific challenges with customer applications, identifying ways to improve the application developer experience, streamlining application debugging and troubleshooting, improving observability, developing test plans for automated and user testing, and exploring emerging technologies as the platform evolves.

This is an Individual Contributor role that reports to the CEO/CTO, with growth-path options to technical lead, staff/principle, or management.
