Software Engineer – Platform Services Position Summary This is a mid-level individual contributor on the Platform Services team. This role focuses on building and maintaining the foundational systems that power identity, authentication, and integration capabilities across MeridianLink's multi-product SaaS platform. Platform Foundation is a small, high-output team. It runs lean by design, with the expectation that the right combination of engineering depth and AI-assisted tooling can achieve platform-scale impact with a minimal footprint. Engineers here are expected to understand the systems they own deeply enough to identify what needs to be built next, flag problems before they become incidents, and ship with the kind of care that keeps downstream product teams unblocked. The immediate focus of this role is federated identity and authorization infrastructure. The work ahead involves building and extending the platform services that product teams depend on to authenticate users, enforce authorization, and manage access at scale. A strong candidate for this role has hands-on experience with OAuth 2.0, OIDC, SAML, and JWT, understands how authorization frameworks work in practice, and knows what it takes to integrate identity services into real-world applications. Equally important is how this person approaches their craft. Platform Services run with AI-assisted workflows as a first-class part of how software gets designed, validated, and delivered. Engineers on this team are expected to be fluent users of AI development tools, not just passive consumers of them. If you want a role where AI is a force multiplier and not an afterthought, this team is built around that idea. Key Competencies At this level, competencies reflect technical ownership of well-defined work, growing independence, and the beginning of a mentorship posture toward more junior engineers. Technical Execution & Delivery Delivers features end-to-end with limited guidance; takes a scoped requirement through design, implementation, testing, and production release Independently identifies edge cases and failure modes within the scope of assigned work Writes clean, maintainable code and participates actively in code review with constructive, specific feedback Proactively surfaces blockers or ambiguities rather than waiting for check-ins Identity & Authorization Systems Applies practical knowledge of federated identity standards including OAuth 2.0, OIDC, SAML 2.0, and JWT Understands how authorization frameworks function: how they enforce policies, how they integrate into upstream and downstream services, and how access decisions are modeled and evaluated Reasons clearly about token lifecycle, session management, and the security implications of identity design choices Integration Engineering Understands the mechanics of connecting distributed services in a multi-product platform environment Builds and maintains integrations that are observable, fault-tolerant, and respectful of downstream consumers Writes and works with API contracts (REST, event-driven patterns) with attention to versioning and backwards compatibility AI-Forward Engineering Actively uses AI-assisted development tools (Claude Code, Codex, etc.) to accelerate design, implementation, and validation Participates in building and improving AI-assisted workflows and evaluation harnesses that improve the team's delivery throughput Stays current on how AI tooling is evolving and brings new approaches to the team where they apply Craft & Professionalism Writes tests with enough coverage to catch regressions without over-engineering the test suite Contributes to operational health: monitors what they've shipped, responds to issues, and follows incidents to resolution Documents what needs to be documented; keeps tribal knowledge out of individual heads and into shared systems Expected Duties Identity & Authorization Platform Development Build and extend platform services that
