Treewalk is a full-service accounting firm serving a diverse client base across public companies, private enterprises, First Nations, and government entities. We combine deep technical expertise with a forward-thinking culture – and we’re looking for someone to take the next steps of AI integration into accounting with us. We’re building custom internal systems at the cutting edge of agentic AI in the accounting and finance space.

The Senior Software

Engineer will be the hands‑on architect and builder of the new systems shaping our business — and the technical counterpart to our internal product leadership. You’ll design and build the systems that run Treewalk’s business — internal tools, integrations, and workflow automations — using AI coding tools to accelerate delivery without sacrificing quality. You’ll operate as a hands‑on builder who starts from accounting processes and business operations, translates them into clear technical specifications, and ships robust, production‑grade solutions.

You will own the technical direction of our product stack: architecture decisions, security posture, code quality standards, and how we scale responsibly as these tools move from internal use to client‑facing deployments. In this role you’ll regularly navigate ambiguous problem spaces and serve as the technical anchor for AI‑native software development practices at Treewalk. You’ll help define what the future of accounting work looks like — through thoughtful, responsible development of a finance and accounting suite of tools built on modern AI infrastructure.

Architect, build, and iterate on internal AI‑powered tools — invoice processing, accrual workflows, document classification, client reporting,



and more Write production‑quality code and set the technical bar for how the team builds, reviews, and ships software Define and enforce security, data handling, and access control standards as tools expand to client environments Technical Leadership
