Note: The job is a remote job and is open to candidates in USA. Arcadia helps healthcare providers and payers transform complex data into actionable insights that improve patient care, reduce costs, and support better health outcomes. The Principal Software Engineer will own and evolve the agent AI platform, including its runtime, infrastructure, quality attributes, security, and production operations, while partnering with engineering teams and coaching senior engineers.
Responsibilities
- 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
Skills
- 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
- 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
Benefits
- Remote-first across the US
- A flexible culture with personality and heart
