B2B • Fintech • Accounting

Treewalk is an innovative accounting firm that leverages AI technology to provide comprehensive accounting solutions for businesses. They offer services such as bookkeeping, financial reporting, and CFO support, focusing on delivering value and growth for their clients. Treewalk emphasizes a flexible and collaborative work environment, empowering both their team and clients to navigate challenges effectively and embrace new opportunities for advancement.

📋 Description

• 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. • 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. • 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. • 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.

🏖️ Benefits

• 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
