Title: Senior Software Engineer Location: Remote - Canada

About the Role

AlphaSense is seeking an exceptional engineer to own our Excel plugin strategy, bringing the power of AI-driven market intelligence directly into the workflow of financial professionals worldwide. You'll build the bridge between our cutting-edge AI platform and the tool that millions of analysts, investors, and researchers use every day – Microsoft Excel. You'll create experiences that feel magical to users. Your work will directly impact how the world's leading financial institutions make critical decisions.

Who You Are:

• 5+ years building and operating large scale production systems
• Deep expertise in JavaScript/TypeScript and modern development practices
• Strong understanding of asynchronous programming, state management, and event-driven architectures
• Experience with enterprise software deployment, updates, and version management
• Track record of building performant applications with excellent error handling and recovery
• Excellence in debugging complex integration issues and memory/performance optimization
• Ability to mentor teams and establish development best practices

Preferred:

• Production experience with Office JavaScript API, VSTO, or COM add-ins
• Knowledge of Excel's calculation engine, object model, and common power-user patterns
• Understanding of financial modeling, data analysis workflows, or trading systems
• Experience with React and modern frontend frameworks

Technical Environment

• Office JavaScript API / Office Add-ins framework
• TypeScript, React, and modern frontend tooling
• Complex state management between local and cloud data
• Enterprise authentication (SSO, OAuth, SAML)
• Cross-platform support (Windows and Mac)

What You'll Do

• Build the Excel Experience: Develop and ship production-grade features for the Excel plugin that integrate AlphaSense's capabilities while respecting Excel's performance and stability requirements
• Navigate Complex Integration: Work with Excel's object model, calculation engine, and event system to deliver features that feel native while accessing cloud-based intelligence
• Optimize Relentlessly: Make complex operations feel instantaneous, manage memory carefully, and ensure the plugin never slows down Excel
• Uphold Best Practices: Follow and contribute to team standards for development, testing, deployment, and monitoring of Office plugins, and support junior engineers through code reviews and pairing

Impact You'll Have

You'll fundamentally change how financial professionals interact with market intelligence. Within your first year, you'll ship a plugin used by thousands of analysts at leading financial institutions, making AI-powered research as simple as typing an Excel formula. You'll eliminate the context-switching between Excel and research platforms, saving analysts hours daily while improving the quality of their analysis.

More importantly, you'll establish the technical foundation and best practices that will guide our Office integration strategy for years.

Why This Role is Unique

This isn't just another plugin development role. You'll be working with:

• Cutting-edge AI capabilities that need to feel simple in Excel
• Financial professionals who depend on Excel for critical decisions
• Complex technical constraints that require creative solutions

You'll need to think like a financial analyst, architect like a distributed systems engineer, and optimize like a game developer. It's a rare opportunity to work on deeply technical challenges while directly impacting how the financial world operates.
