## About the Role

Software Engineering, Order Delivery, Healthcare, Cost Control, Customer Relations, Operational Audit, Clinical Assessment, Startup, Automation, Artificial Intelligence (AI), * Scars from production LLM/agent deployments beyond glossy demos (but we won't ask for 20 years of LLM experience).

 * Pragmatism about the LLM ecosystem: excited by it, not distracted by it.
 * Regulated-data experience (HIPAA, PHI, SOC 2 or HITRUST environments).
 * A public voice through talks, writing, or open source.

## Description

* Evolve and run our agent platform for both internal and client-facing use cases: the runtime, SDKs, templates, and paved paths that let teams ship agents on Arcadia's data. You write a meaningful share of the code.
 * Stand up and harden the infrastructure underneath it: IaC, network topology, security controls, and the operational tooling that keeps it running, in close partnership with SRE.
 * Make quality attributes platform defaults, not per-team projects: evaluation harnesses and regression gates, guardrails and policy enforcement, tracing and telemetry, and resiliency patterns for model, tool, and data failures, plus the inevitable provider churn.
 * Design for a regulated industry: PHI isolation, least-privilege identity for agents, audit trails, and human review.
 * Run the platform as an internal product: work with the teams building on it every week, and measure adoption and developer experience.
 * Partner with domain teams on their hardest agent use cases, and turn what you learn into platform capability.
 * Own it in production: SLOs, on-call, incident response, and postmortems.
 * Set the technical bar for how engineers build with AI at Arcadia, and coach Senior Engineers through design partnership and review. Their trajectory is part of your impact.

What You'll Bring

 * Platforms you've built and run that other engineering teams adopted, from ambiguous beginnings through years of operation, with results you can show.
 * Deep foundations in cloud-native distributed systems, data infrastructure, and service architecture. You reason from first principles.
 * Hands-on infrastructure depth: IaC, cloud, security architecture, and running production systems. You can go deep with SRE, not just hand work off to them.
 * Current, hands-on production coding, and the desire to keep doing it.
 * Passion for developer experience (DevEx/DevProd) as a discipline.
 * Writing clear enough to set standards beyond your own work, and influence that comes from credibility, not title.
 * No healthcare background required. We hire builders from fintech, infrastructure, and consumer scale, and teach the domain.

Would Love for You to Have, This position is responsible for following all Security policies and procedures in order to protect all PHI under Arcadia's custodianship as well as Arcadia Intellectual Properties. For any security-specific roles, the responsibilities would be further defined by the hiring manager.
