Embedded Client Platform Engineer

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 For base compensation, we set standard ranges for all roles based on function and level benchmarked against similar stage growth companies and internal comparables.
