Senior Software Engineer – Agent Experiences at Alpaca

Our company

5+ years of software engineering experience building and operating production backend systems
Evidence of scope and ownership matters more than a strict year count
Shipped autonomous execution: software that took actions under an explicit policy without a person approving each action, and that rejected or stopped actions outside that policy
Designed and implemented account-level policy in an application: durable rules for what a caller may do, enforced on the action path, with an audit of the decision
Experience with MCP architecture to work with stateless and stateful behavior, and building to MCP, or to connector, plugin, or skill standards as they have changed in production
