Full Job Description
Software Engineer III – 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. This is a fully remote role. 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 guida
