Note: The job is a remote job and is open to candidates in USA. Arcadia is dedicated to happier, healthier days for all, believing in a better healthcare world powered by data. They are seeking a Principal Software Engineer to take technical ownership of the User Management system, leading the rearchitecture and implementation of a secure access control framework.
Responsibilities
- 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
Skills
- 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
- 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
Benefits
- Flexible Time Off (~22-day company average)
- Competitive compensation, comprehensive benefits
- 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
