Principal Design Engineer

You will play a key role in shaping the future of AlphaSense's product experience as a senior individual contributor, leading through craft, systems thinking, and technical excellence to build AI-powered experiences that feel tailored, intelligent, and essential to customers' workflows. You'll operate at the intersection of design, engineering, and product strategy, translating complex, data-rich problems into high-quality, production-ready experiences. You won't just prototype ideas; you'll define how they are built, scaled, and experienced in the product. As a senior member of the Design team, you'll act as a multiplier, mentoring others, guiding technical and design decisions, and strengthening the connection between user needs, business goals, and engineering realities.

Responsibilities

• Create high-fidelity, coded prototypes and interaction models that bring complex, AI-powered workflows to life and clearly communicate product direction
• Own high-impact initiatives from concept through production, shipping experiences that reflect strong design thinking, technical rigor, and a deep understanding of customer workflows
