Sr. Platform Engineer

Posted 14 hours ago

Istari Digital is on a mission to build the world’s best digital engineering ecosystem, making digital threads, models, and simulations easier, more secure, and more collaborative. Led by former U.S. Air Force acquisition chief Will Roper, the company aims to democratize what they call the engineering metaverse — where technologies are created digitally, reducing costs, time, and environmental impact. They partner with aerospace, defense, and industrial customers to certify and virtualize complex hardware systems, including a recent prototype with Lockheed Martin to digitally certify an aircraft under a U.S. Air Force contract.

Job Description

We are seeking a Senior Platform Engineer to join our Core Platform team. In this role, you will own and evolve the end-to-end architecture of the Core Platform, including backend services, SDKs, AI-enabled capabilities, and supporting infrastructure.
You will design and operate scalable APIs, event-driven systems, distributed services, and AI-integrated workflows, ensuring high standards for reliability, performance, observability, and security. This role requires strong architectural judgment, hands-on technical leadership, and the ability to collaborate cross-functionally to deliver extensible platform capabilities that support both traditional integrations and AI-driven use cases.
You will help set technical direction, mentor engineers, and drive engineering best practices across the team.
