Original job description

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.

The Role

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.

What Your Days Will Look Like

Product development

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
Partner with internal accounting staff to understand process pain points and translate them into clean system designs
Define and enforce security, data handling, and access control standards as tools expand to client environments

Technical Leadership

Own architectural decisions: service design, data models, API contracts, queue/worker patterns, cloud infrastructure
Establish code quality standards and review practices, including responsible use of AI-generated code
Identify and mitigate technical risk proactively - especially as systems handle sensitive financial data
Document systems clearly so that non-engineers can understand what's been built and why

Collaboration & Iteration

Work closely with the internal product lead (non-engineering background) to bridge business requirements and technical execution
Surface trade-offs clearly and make pragmatic calls under ambiguity
Contribute to hiring and capability-building as the team grows

Requirements

5+ years of software engineering experience building and shipping production systems, products, or platforms
Demonstrated experience building and operating production backend systems: APIs, queues, workers, databases
Strong command of at least one modern backend language (Node.js/TypeScript, Python, Go, or similar)
Solid understanding of cloud infrastructure and deployment (AWS, GCP, Azure, or Render-equivalent platforms)
Experience with common integration patterns: webhooks, REST APIs, event-driven workflows, third-party SaaS connectors
Strong security fundamentals - authentication, authorization, secrets management, data handling for sensitive financial data
Excellent written communication; able to document architecture and explain technical decisions to non-engineers
Comfortable working in a small, high-ownership environment where requirements evolve

Assets

Experience with AI/LLM application development: prompt engineering, tool use, agentic workflows, output validation
Familiarity with low-code/workflow automation platforms (n8n, Make, Zapier) and their integration into code-native systems
Prior work with accounting or finance software APIs (QuickBooks, Xero, or similar)
Experience with document processing pipelines (OCR, PDF extraction, classification)
Background working in or alongside finance, accounting, or professional services environments

Benefits

Treewalk For a Reason

This is a formative role in a fast-growing service line - you'll have real influence over the architecture, culture, and direction of how we build
A collaborative, supportive team that takes the work seriously without taking itself too seriously
Flexible working arrangements and a genuine commitment to work-life balance
Extended healthcare benefits from Day 1 - no waiting period

Who We Are

Treewalk is a Vancouver-based advisory and accounting practice serving a diverse client base across technology, financial services, and other sectors. We bring the same rigour and high standards of financial reporting that built our reputation in public company work to organizations of all sizes and industries. We are one of the fastest-growing accounting firms in Canada with big goals and an anti-firm culture - think tech startup, but accounting. We are moving away from traditional top-down hierarchy and toward a more autonomous, ownership-driven model of governance. Our ambition is to become the go-to destination for finance professionals who want to build deep expertise, do meaningful work, and grow fast.

Our Core Values

Mastery  - We pursue knowledge and aspire to be the best at our craft, constantly building on our expertise
Support  - Teamwork and collaboration are our bedrock. You're never alone at Treewalk
Ownership  - We own our mistakes and our outcomes. Responsibility to our colleagues and clients is non-negotiable
Kaizen  - Change for the better. Nothing is perfect, but we're always striving for it anyway

Annual Salary: $135,000-150,000
