Responsibilities

AlphaSense runs a large-scale, Kubernetes-native platform built on a modern microservices architecture, serving the majority of the Fortune 500. We're now moving it into a cell-based architecture, where each cell is an independent deployment of the platform, and the cell count is heading from dozens toward hundreds, including private and isolated clouds.
Platform tooling only takes that so far. The rest of the problem is architectural and it sits in the services: how they're structured, how they're bounded, and what they assume about the environment they run in. This role owns that side of the work.
You'll set the architectural direction for how our services scale horizontally across regions, cells and deployment models, and you'll build it rather than specify it. You'll own the environments configuration management framework to operate environments as a fleet, and the services and libraries to make it work. Where the answer is a re-architecture rather than a patch, you design it and you write it. Much of it lands in code other teams own, so influence matters as much as design.
The scope is deliberately broad: hundreds of services, several languages, and the latitude to go after whichever scalability limit matters most. Our main languages are Java, Python, React and Rust.
We use AI tooling heavily and expect the same from you, along with a view on how the rest of engineering should be using it.
Drive the service-side changes cell architecture needs: re-architecture, shared library, etc.
Decompose hundreds of microservices into sub-systems with independent lifecycles
Find and close horizontal scalability gaps across regions, cells and deployment models
Own the environments application configuration management framework end-to-end
Own the services and libraries specific to private and isolated cloud deployments
Design and land changes directly in product services, partnering with the teams that own them
Set the architecture patterns and reference implementations product teams build against
