About the Team:
Our diverse Product & Engineering team values innovation, collaboration, and the continuous improvement of our platform. We offer a dynamic work environment where employees can grow and thrive while working on cutting-edge technology that shapes the future of AI and search.
At AlphaSense, we believe that diverse experiences and perspectives are critical to our success. We are committed to creating an inclusive workplace where all employees feel valued and empowered to be their authentic selves.
About the Role:
Own and evolve AlphaSense's embedded client platform, starting with Excel, to bring AI-powered market intelligence directly into the daily workflows of financial professionals. This role is responsible for building mission-critical integrations inside constrained host environments where performance, correctness, and user trust are non-negotiable.
Excel and PowerPoint are the first and most important host environments today, but the mandate is broader: define durable client-side integration patterns that can scale across tools, workflows, and future analyst surfaces.
This is a Staff-level role with significant architectural ownership, deep hands-on work, and long-term leverage across the product.
Why this role is important:
Financial professionals live in Excel. One data corruption bug, one performance regression, or one broken enterprise deployment can permanently erode trust. At the same time, Excel is a highly constrained, non-owned runtime with sharp edges, undocumented behavior, and strict performance ceilings.
We are looking for an engineer who thrives in hostile integration environments, not someone who treats Excel as "just another web view."
Who You Are:

• 7+ years building and operating production user-facing software
• Proven experience embedding software into a non-owned host environment
• Strong JavaScript/TypeScript skills and event-driven programming experience
• Track record of performance profiling and optimization in constrained runtimes
• Zero-tolerance mindset for data corruption and reliability issues
• Experience with enterprise deployment, updates, version skew, and rollback
• Strong testing and observability instincts for client-side systems
• Ability to mentor engineers and set technical standards

Nice to have:

• Built systems where <100ms latency materially impacted user trust
• Experience debugging non-deterministic, stateful, event-driven systems
• Background in financial systems, trading tools, or analyst workflows
• Experience with offline-first architectures and sync
• History of working effectively with enterprise IT and security teams

What You'll Do:
Near-Term (Excel-Focused)

• Own the architecture and reliability of AlphaSense's Excel integrations (Office Add-ins, JS/TS, legacy components)
• Define clear boundaries between workbook state, plugin state, and cloud state
• Ensure zero data corruption and strict Excel file integrity guarantees
• Make complex operations feel instantaneous (<100ms local, <500ms remote)
• Design for offline, slow networks, and enterprise restrictions (proxy, SSO, locked-down IT)
• Establish testing, observability, and deployment best practices for desktop/embedded environments

Medium-Term (Platform Leverage)

• Unify fragmented Excel tools into a single, coherent client architecture
• Create reusable abstractions for embedded client development
• Define patterns that reduce Excel-specific fragility over time
• Mentor other engineers working in constrained client environments
