About
the Role We are seeking an exceptional Principal Software Engineer to provide technical leadership, architectural vision, and team mentorship for our core engineering group. In this role, you will be the primary architect and public face of a cloud-agnostic software platform that helps enterprise customers provision, scale, and orchestrate Apache Airflow instances completely on-premises within their own environments. This is a unique infrastructure challenge: our platform is designed to be completely self-contained, operating without reliance on an external SaaS backbone or mandatory outbound communication. Both our control plane and data planes deploy locally inside the customer’s infrastructure. You will lead the engineering team in defining, designing, and building these systems to function reliably across a spectrum of enterprise network setups—ranging from standard customer-managed clouds to strictly isolated, air-gapped environments.
What You'll Do Define, Design, and Build Core Architecture : Own the end-to-end definition, design, and implementation of both the control plane and data plane services, creating highly resilient inter-connections between them to power this self-contained infrastructure platform. Architect an Extensible Platform API : Drive the design, data modeling, versioning, and long-term backward compatibility of robust APIs (such as REST or gRPC). These APIs serve as the core platform engine that power the customer-facing UI, and the developer endpoints for customer-facing programmatic integrations. Design Comprehensive Platform Observability : Architect the telemetry framework (metrics, logs, and traces) for the self-contained platform itself, ensuring deep visibility into both the core control plane services and the performance, health, and status of the underlying Airflow instances it provisions. Architect for Varied Isolation Levels : Oversee the architecture of a self-contained software platform, ensuring all services, images, dependencies, and configurations can run smoothly whether deployed in connected private clouds or highly secure, zero-egress networks. Provide Technical Leadership : Act as the technical face of
