Principal Engineer (Platform Integration)

As a Principal Software Engineer on the Platform Services team, you will serve as the senior technical authority for the services layer of the platform – a portfolio of services spanning data processing, file transfer, financial data feeds, communications, compliance, and shared infrastructure. Reporting to the Engineering Manager, you will own the reliability, observability, and modernization of these services across multiple production ecosystems. This is a pure IC role. Your job is to write great code, make sound architectural decisions, and drive the technical evolution of a mission-critical platform that was recently migrated to Azure and is now entering a cloud-native modernization phase. You will be the go-to technical voice for platform reliability, resilience, and shared engineering standards on the Platform Services Team, partnering closely with the Scalable Architecture Team as they define the future-state design patterns this portfolio will adopt. The services you own span a wide range of modernization stages – some recently refactored, others carrying significant technical debt. Your immediate mandate is improving the reliability and resilience of these services in their current state – reducing fragility, improving observability, and ensuring production stability across multiple ecosystems. The longer-term opportunity is to partner with the Scalable Architecture Team to determine the right cloud-native path forward and sequence the modernization of legacy services into that future state. You will bring an AI-first mindset – genuinely integrating agentic development tooling into your daily workflow and setting the standard for your team.
