Key Responsibilities:

Play a key role in designing, developing, and architecting our microservices and Temporal workflows behind money movement, trading, and account lifecycle.

•
We are a technology-first company, leveraging a cloud-native technology stack (Temporal, Kubernetes, Istio, AWS), AI and automation tools and agents for development and testing.
•
You make architectural decisions across a variety of systems and raise the bar on how we test these systems that must be correct.
•
Own gRPC services end-to-end in a multi-tenant platform along with partner-facing REST APIs.
•
Tackle really tough engineering and product problems and operate what you build. Instrument services in Datadog; own traces, dashboards, and monitors in your area.
•
Build and debug integrations with custodians, clearing systems, banking partners, and calculate and generate tax documents.
Qualifications:
