Senior Engineer, Platform

Every audit answers one question: can I trust this? For 150 years, people have answered it by hand. Clark is changing that.

We build AI that doesn’t just assist auditors. It does the audit work itself. More than 35 CPA firms already use Clark to run audit fieldwork faster and at equal or better quality. Audit is where we start. Our mission is to build the trust infrastructure layer for the AI economy, and we’re only getting started.

We’re a small, hard-working team backed by top investors. We take ownership and judge ourselves by results. If you want to change how an entire profession works, you’ll fit in here.

We are hiring Senior Platform Engineers to build the product and systems through which customers experience Clark.

You will own features from initial customer problem through frontend experience, backend architecture, data models, integrations, deployment, and production operation.

This is a broad engineering role for someone who enjoys moving across the stack, working directly with users, and solving the highest-leverage technical problem regardless of where it lives.

You will help build customer-facing workflows, integrations, shared services, internal tools, and the engineering foundation that allows Clark to scale.

Clark’s customers operate across complex workflows involving documents, accounting systems, workpapers, approvals, evidence, and collaboration. Our product must make those workflows simpler without sacrificing reliability, security, or control.

Full-stack engineers turn Clark’s AI capabilities into complete products that customers can deploy, understand, and trust. They also build the integrations and platform foundations that allow Clark to connect with existing systems and support increasingly complex enterprise workflows.

The systems you build will directly affect customer adoption, product velocity, reliability, and Clark’s ability to scale.
