• Implement core domain logic that drives key product workflows and system behavior
• Ingest and process high-volume usage and event data from customer-facing endpoints
• Build backend services that support operational, analytics, and reporting use cases
• Model, persist, and manage domain data, enabling querying, filtering, and lifecycle management
• Expose well-designed APIs and webhooks consumed by customers, UIs, and external systems
• Power customer-facing UI experiences by providing backend APIs for visibility, analytics, and configuration

Requirements

• 3–5+ years of professional software engineering experience building backend services and distributed systems in the Java ecosystem (Java, Spring Boot, Maven/Gradle)
• Strong understanding of event-driven architectures, asynchronous processing patterns, messaging systems, and distributed system design
• Proven experience designing and maintaining RESTful APIs, web hooks, and service-to-service integrations
• Comfortable operating in AWS, GCP, or Azure environments and working with modern observability tooling, logging, and monitoring platforms
• A track record of delivering performant, reliable and scalable applications
• Excellent collaboration and communication skills in cross-functional teams
• Experience building products in cybersecurity, identity, governance, compliance, data protection, or enterprise SaaS environments
• Understanding of architectural decisions and their impact
• Ability to balance scalability, reliability, maintainability, and speed of execution
• Critical thinking about security, observability, and operational excellence
• Familiarity with blending software development, distributed systems and data-intensive applications
• Strong familiarity with authentication and identity technologies such as OAuth, OpenID Connect (OIDC), SAML, SCIM, Entra ID (Azure AD), Okta, or other enterprise identity providers
