Sr. Software Engineer - Platform Services - meridianlink

POSITION SUMMARY

This is a Senior-level individual contributor on the Platform Services team. The team builds the foundational infrastructure that all MeridianLink products depend on: centralized authentication, authorization, user management, and the shared services layer that enables a multi-product SaaS platform to operate as one system.

Platform Services runs lean by design, engineers own their domain deeply, and ship production features with minimal oversight. The immediate focus is federated identity and authorization infrastructure: extending the identity platform, hardening what's already in production, and supporting product teams as they integrate.

Over time, the team's scope will expand into platform capabilities that directly support AI product development, including shared backend services that encapsulate cross-product functionality and AI-powered features.

This is a fully remote role.

KEY COMPETENCIES

What it means to be a Senior Engineer at MeridianLink

• Identifies edge cases and failure modes independently within assigned scope
• Participates actively in code review with constructive, specific feedback
• Surfaces blockers early rather than waiting for check-ins

Craft & Professionalism

• Writes tests that catch regressions without over-engineering the suite

• Reasons clearly about token lifecycle, session management, and the security implications of identity design choices

Platform & Integration Engineering

• Builds shared services that multiple product teams consume through well-defined APIs
• Designs with multi-tenant and multi-product constraints in mind: data isolation, tenant-scoped configuration, and cross-product user identity
• Writes API contracts (REST, event-driven patterns) with attention to versioning, backwards compatibility, and developer experience

Domain Context
