 * Strong backend skills (Python, Node.js, C#, or Java)
 * Comfort with cloud-native environments (Docker/Kubernetes, AWS/Azure/GCP)
 * Experience with distributed systems, event-driven architectures, message queues, observability
 * Experience with structured/unstructured data, ideally time-series or financial data

## Description

This is a U.S. remote role for a Senior Software Engineer who wants to build at the frontier of agentic finance. You'll work directly on Era Context, our MCP server. Designing and maintaining the tool schemas and endpoints that let LLMs query and act on financial data safely, extending our connector integrations, and building the backend systems (transaction sync, categorization, insights, automation rules) that power it. You'll be working in genuinely new territory - there's no established playbook for "backend engineering for MCP servers," so you'll help write it.
