Principal Software Engineer – Platform Engineering

Overview

Principal Software Engineer on the Platform Engineering team, setting the architectural direction for scaling AlphaSense's Kubernetes-native microservices platform across regions, cells and deployment models.

What you'll do

• Drive the service-side changes cell architecture needs, including re-architecture and shared libraries.
• 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.
• Make configuration a runtime concern rather than something baked into service code.
• Partner with Cloud Platform, SRE and DevEx on where the service and platform boundary should sit.
• Raise the architectural bar across the org and mentor Staff and Senior engineers.
• Embed AI tooling into day-to-day development for lasting productivity gains.

What you'll need

• Deep hands-on architecture experience in large microservice estates, at least in hundreds of services.
• Strong in Java and Python, and willing to contribute to other tech stacks if needed.
• Track record decomposing large service estates into sub-systems that can evolve independently.
• Proven experience designing for horizontal scalability across regions and independent deployments.
• Experience with cell-based, multi-tenant or multi-region architectures.
• Strong cloud-native background: Kubernetes, containers and AWS.
• Experience externalising configuration and removing environment coupling from application code.
• Demonstrated ability to land significant changes in code owned by other teams.
• A record of spotting architectural limits before they turn into incidents.
• Ability and desire to design, lead, influence and deliver on ambitious technical roadmaps.

Nice to have

• Experience with Vespa.
• Experience with private, isolated, on-premise or air-gapped deployments.
• Design and stewardship of shared libraries or internal frameworks used by many teams.
