Principal Software Engineer, User Management

What You'll Be Doing

Leading the rearchitecture and modernization of the User Management platform — authentication (Auth0, SAML 2.0, OAuth2, JWT), authorization, access control, and user provisioning across Arcadia products

Building backend services and APIs across a polyglot stack ( TypeScript/NestJS, Go, Python ) supporting secure, multi-tenant access models

Owning Auth0 tenant management, cross-application SSO, and session infrastructure — including SAML integrations, identity provider relationships, and Hydra session management

Managing cloud infrastructure through Infrastructure-as-Code (Terraform/Terragrunt) and AWS-native services (Lambda, API Gateway, DynamoDB, Cognito, SNS)

Defining SLOs and designing telemetry for key features, ensuring robust monitoring, canary, and standard rollout strategies — with shared ownership of on-call reliability

Partnering with cross-functional stakeholders — including Product, Security, and SRE — to ensure alignment between technical execution and organizational priorities

Providing leadership, mentorship, and clarity in complex, ambiguous problem spaces

What You'll Bring

10+ years of professional full-stack software engineering experience with a focus on backend and distributed systems

Proven success building and scaling identity and access management systems , including authentication (SAML 2.0, OAuth2, JWT) and fine-grained authorization frameworks

Expertise in TypeScript , Node.js/NestJS , and modern React/Angular development for full stack delivery

Hands-on experience with agentic AI-assisted development — actively using agentic coding tools, context-engineered environments, and AI-augmented workflows, with a track record of independently shipping AI-native tooling and defining how teams leverage AI strategically

Strong command of cloud architecture (AWS preferred) and IaC practices with Terraform

Deep experience with relational and NoSQL data stores , designing for vertical & horizontal scalability and high availability

Demonstrated ability to own complex systems from design through rollout and post-release operation , with strong attention to quality and reliability

Strong communication, collaboration, and architectural reasoning skills — able to work across engineering, product, SRE , and security teams while balancing pragmatism with long-term technical health

Would Love for You to Have

Experience modernizing identity and access systems or other critical, cross-cutting platform services

Familiarity with API gateway design, centralized JWT validation, and event-driven architectures

Exposure to data streaming or message-driven systems (Kafka, Kinesis, SNS/SQS)

Experience in healthcare technology, HIPAA compliance, or other regulated data environments

Polyglot engineering experience — comfortable working across multiple languages and frameworks (e.g., Python, Java, Go) when solving complex distributed system challenges

Experience building internal developer tooling, custom agents, or platform-level AI integrations that go beyond individual productivity — shaping how an engineering organization adopts and scales AI-assisted development

What You'll Get

The opportunity to own one of Arcadia's most critical platform domains and drive its evolution for scale and reliability

A mission-driven culture where your work improves patient outcomes and healthcare delivery

Competitive compensation, comprehensive benefits, and Flexible Time Off (~22-day company average)

A collaborative, remote-friendly engineering culture that values innovation, curiosity, and technical excellence

A team that is actively investing in AI-augmented engineering practices — you won't just use these tools, you'll help define how the organization adopts them
