About the role
Cranston is building the AI back office for accounting firms, combining the judgment of experienced operators with the leverage of AI agents and reliable software.
We automate the most complex manual workflows inside CPA firms: tax preparation, bookkeeping, document collection, cleanup, review, close, and client operations.
Cranston is already deployed with accounting firms across the country, helping them serve more clients, reduce bottlenecks, and give their best people time back for higher-value work.
About the role
You will work across product, design, engineering, and implementation. Some days that means mapping how tax packages move through a firm. Other days it means building a review workflow, designing an agent loop, tightening data models, or debugging why a customer workflow failed in production.
This is a product engineering role for someone who wants to build the system, not just spec it. You will turn what we learn from firms into durable product: interfaces, automations, review loops, workflow primitives, data models, and agent behavior that work across customers.
Cranston is vertically integrated across software, AI agents, and managed back-office operations. That makes the problems unusually concrete: if the product is wrong, the work breaks. If the product is right, firms can take on more clients without adding headcount.
What you will do
- Own core product workflows for tax prep, tax review, bookkeeping, client requests, and practice-management operations.
- Design and build product abstractions that turn messy accounting work into repeatable, reviewable systems.
- Use Cranston's internal agent platform to move from product context to working software quickly, then inspect the result until it is right.
- Build interfaces, workflow states, data models, and agent behavior that hold up in live customer usage.
- Codify repeatable patterns from customer deployments back into the main product.
