## Description

Join a fast-growing software company that is transforming how organizations manage and leverage large-scale scientific and operational data. This is a full-time opportunity for a Senior .NET Engineer to build cloud-native applications and distributed systems using C#, .NET, React, TypeScript, and AWS. You'll work on highly scalable products that process complex datasets, integrate with external platforms, and support mission-critical business workflows. Based remotely within the United States.

This is an opportunity for an engineer who enjoys solving difficult technical challenges rather than simply maintaining applications. You'll help design modern microservices, improve platform reliability, drive architecture decisions, and contribute to products that have a direct impact on customers. The team is looking for someone who can operate across the stack, troubleshoot production systems, and help scale a rapidly evolving cloud platform.
