Senior Software Engineer

This is a fully remote position, open to applicants in Canada.

📋 Description

• You will design and develop the systems that drive Treewalk's operations — including internal tools, integrations, and workflow automations — leveraging AI coding tools to expedite delivery while maintaining high quality.

• Your role will involve hands-on building, starting with accounting processes and business operations, converting them into clear technical specifications, and delivering robust, production-ready solutions.

• You will be responsible for the technical direction of our product stack: making architecture decisions, ensuring security posture, setting code quality standards, and scaling responsibly as these tools transition from internal use to client-facing implementations.

• In this position, you will frequently tackle ambiguous problem areas and serve as the technical cornerstone for AI-driven software development practices at Treewalk.

• You will shape the future of accounting work through the thoughtful and responsible development of a finance and accounting suite of tools based on modern AI infrastructure.

• You will architect, build, and refine internal AI-powered tools — such as invoice processing, accrual workflows, document classification, client reporting, and more.

• You will write production-quality code and set the technical standards for how the team develops, reviews, and delivers software.

• You will collaborate with internal accounting staff to identify process pain points and translate them into effective system designs.

• You will define and enforce security, data handling, and access control standards as tools expand into client environments.

• You will own architectural decisions related to service design, data models, API contracts, queue/worker patterns, and cloud infrastructure.

• You will establish code quality standards and review practices, including the responsible use of AI-generated code.

• You will proactively identify and mitigate technical risks, particularly as systems manage sensitive financial information.

• You will document systems clearly, enabling non-engineers to understand what has been built and the rationale behind it.

• You will work closely with the internal product lead (who has a non-engineering background) to connect business requirements with technical execution.

• You will clearly present trade-offs and make pragmatic decisions amidst uncertainty.

• You will contribute to hiring and building capabilities as the team expands.

⛳️ Requirements

• A minimum of 5 years of software engineering experience in building and deploying production systems, products, or platforms.

• Proven experience in constructing and operating production backend systems: APIs, queues, workers, and databases.

• Strong proficiency in at least one modern backend programming language (Node.js/TypeScript, Python, Go, or similar).

• A solid understanding of cloud infrastructure and deployment (AWS, GCP, Azure, or equivalent platforms).

• Familiarity with common integration patterns: webhooks, REST APIs, event-driven workflows, and third-party SaaS connectors.

• Strong fundamentals in security — covering authentication, authorization, secrets management, and data handling for sensitive financial data.

• Exceptional written communication skills; capable of documenting architecture and articulating technical decisions to non-engineers.

• Comfortable working in a small, high-ownership environment where requirements are subject to change.

🏝️ Benefits

• This is a key role in a rapidly growing service line — you will have significant influence over the architecture, culture, and direction of our development efforts.

• A collaborative and supportive team that takes their work seriously but maintains a light-hearted atmosphere.

• Flexible working arrangements with a genuine focus on work-life balance.

• Extended healthcare benefits starting from Day 1 — no waiting period.
