AI Engineer – Trust & Explainability (AI Platform)
Role Overview
The AI Platform team is building the shared runtime that every AI agent at MeridianLink will run on as part of the MeridianLink One platform: model gateway, orchestration, memory, and observability, delivered as reusable services so product teams build agents once and run them safely for hundreds of credit union and lender customers. This role builds the trust and explainability layer of that runtime: the tracing, evaluation, and explanation capabilities that let engineers understand exactly what a multi-agent workflow did and why, and that let product teams show end customers the right level of explanation to trust an agent's output.
This role has a strong dotted-line relationship to MeridianLink's Security Operations team, so the platform's trust guarantees and Security's threat models are built from the same picture.
About the Opportunity
This is a deeply technical, hands-on engineering role and an integral part of the platform itself.
You will write the code that traces agent actions across a multi-agent workflow, adopt and extend leading open-source explainability and observability frameworks, and build the primitives product teams use to surface explanations to lenders, credit unions, and their borrowers.
You should have real hands-on experience with LLM-based systems and a strong pull toward the problems of trust, tracing, and evaluation.
You do not need to be an expert in all of it.
This is a place to build that expertise while the platform is being built, working alongside a Staff engineer team lead and architects who will invest in your growth.
