[Remote] Sr. Software Engineer – Platform Services
Note: The job is a remote job and is open to candidates in USA. MeridianLink is a technology company that builds foundational infrastructure for its products. They are seeking a Senior Software Engineer for the Platform Services team to manage identity and authorization services, with a focus on building and extending platform capabilities that support AI product development.
Responsibilities
- Build and extend platform services that manage federated identity, authentication flows, and authorization enforcement across MeridianLink products
- Implement and maintain integrations with the centralized identity platform (FusionAuth), including token handling, session management, user provisioning, and tenant configuration
- Support product teams through their integration process: help them understand the platform's contracts, debug issues, and navigate edge cases in multi-tenant identity behavior
- Build the tooling, documentation, and examples that make those integrations repeatable and self-service over time
- Design and maintain backend services in C# and Python that expose platform capabilities through clean, versioned APIs
- Build with multi-product and multi-tenant scenarios as first-class requirements: data isolation, tenant-scoped configuration, and cross-product consistency
- Participate in API design reviews with attention to contract stability and developer experience for consuming teams
- Use AI development tools as an active part of daily workflow: code generation, design exploration, test scaffolding, and investigation
- Contribute to the team's AI-assisted engineering practices and share what's working
- Build familiarity with the systems that support AI agent development (LLM gateways, orchestration frameworks, evaluation harnesses) so you're ready to own those capabilities as the team's scope grows
- Participate in design discussions and code reviews; give and receive feedback constructively
- Mentor other engineers on the team
- Contribute to documentation and onboarding materials that reduce tribal knowledge
Skills
- 5+ years of professional software engineering experience, delivering features and infrastructure independently in production
- Proficiency with standard development tooling: Git, Docker, automated testing, and modern scripting languages
- Active daily use of AI-assisted development tools
- Bachelor's degree in Computer Science, Software Engineering, or equivalent experience
- Hands-on experience implementing or integrating with federated identity systems using OAuth 2.0, OIDC, SAML 2.0, and/or JWT in production applications
- Practical understanding of authorization frameworks: how policies are modeled, enforced, and integrated into application and platform services
- Proficiency in C# and Python for backend service development, including modern API frameworks (.NET 10+, FastAPI, or equivalent)
- Working knowledge of identity protocol mechanics: authorization code flow, token introspection, claims-based access, assertion handling, and SSO logout behavior
- Experience with multi-tenant SaaS patterns, including tenant-scoped configuration and user identity across application boundaries
- Familiarity with cloud platforms (AWS preferred), including relevant managed services for networking, compute, and secrets management
- Prior experience working with a commercial or open-source identity platform (FusionAuth, Keycloak, Auth0, Okta, or equivalent) in an engineering capacity
- Experience modeling and implementing fine-grained authorization: RBAC, ABAC, or policy-based access control systems
- Prior experience building internal platform capabilities used by other engineering teams
- Experience in financial services, fintech, or a regulated technology environment
- Experience building or supporting AI agent systems: orchestration, tool integration, evaluation pipelines, or LLM gateway infrastructure
- Familiarity with the end-to-end lifecycle of an AI agent, whether internal-facing (developer tooling, automation) or customer-facing (conversational, decisioning)
- Exposure to SOC 2 or similar compliance frameworks from an engineering perspective
