Location: Remote with occasional in-person work in our co-working space in downtown Toronto.

ABOUT FISCAL.AI

Fiscal.ai is a leading research and data platform built for capital markets professionals. Combining a high-performance research Terminal with a modern, near-real-time fundamentals API and MCP server, Fiscal.ai is redefining financial data infrastructure for the AI era. Headquartered in Toronto and backed by $13M in venture capital, the company serves thousands of institutional and professional clients and reaches millions of end-users through its API ecosystem.

Brief Description of the Role

The Fiscal.ai Terminal is used every day by thousands of investors to research companies: financial statements, segments and KPIs, estimates, ownership and insider activity, filings, valuation models, screening, and charting. When a chart won't load, a screen returns the wrong companies, or a paywalled cell unlocks for the wrong tier, our users notice immediately, because they know exactly how the product should behave.

You will own the quality of the Terminal. This is an engineering role, not a QA analyst role. You will find bugs, reproduce them, trace them to root cause across the frontend and backend, and ship the fix yourself. You will build the end-to-end test framework that stops those bugs from coming back. You will work alongside the engineers building the Terminal and the Fiscal.ai data infrastructure.

What you will do

• Own the inbound bug pipeline for the Terminal: Sentry issues, customer-reported problems, and what you find yourself. Reproduce, prioritize, and fix or route every one of them.
• Fix bugs across the stack: the React/Next.js frontend, the Cloudflare Workers backend, and the data layer between them. Investigate to the root cause. Never patch the symptom.
• Design and build the end-to-end test framework for the Terminal (Playwright), get it running in CI against preview deploys, and grow regression coverage of the flows that matter most: financials, charting, screener, portfolio, auth, subscriptions and paywall.
• Write unit and integration tests alongside your fixes so the same class of bug cannot ship twice.
• Turn what you learn into playbooks: debugging guides, test conventions, and tooling the rest of the team uses
  
  If you think this is the perfect fit for you, we'd love to specifically hear why, and which bug in a financial product you are proudest of having found and fixed.

Requirements

• You write good code, fast, and you fix what you find. If you want to file tickets for someone else to fix, this is not the role.
• Proficiency in TypeScript, React, Next.js.
• Hands-on experience building end-to-end test automation (Playwright preferred) and unit tests (Vitest or Jest), and running them in CI.
• Strong debugging skills across the full stack: browser devtools, network traces, server logs, error monitoring, database queries.
• Experience testing and debugging data-heavy applications where correctness matters: finance, analytics, or similar.
• Proven experience or strong interest in investing and finance. Our platform is built by investors, for investors. You should be able to read an income statement, know what LTM and NTM mean, and recognize when a P/E ratio or free cash flow figure is obviously wrong. Ideally you already use Fiscal.ai, or a competing terminal, for your own research.
• Understanding of how paid data products work: subscription tiers, entitlements, paywalls.
• Experience or interest in AI technologies, specifically Large Language Models (LLMs), including using AI coding agents as part of your daily workflow.
• Keen eye for design, UI, UX. You notice the misaligned column and the layout shift.
• Based in Canada.
