AlphaSense is a market intelligence company that empowers professionals to make smarter decisions through AI-driven insights. The role involves owning and evolving the embedded client platform, particularly focusing on Excel, to integrate AI-powered market intelligence into financial professionals' workflows while ensuring reliability and performance in constrained environments.

Responsibilities:

• 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
• 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

Requirements:

• 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
• 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
