Principal Design Engineer in London

The Design team is a strategic driver of product differentiation, shaping how the world’s leading companies make high‑stakes decisions. We believe great UX is not just about usability, but about deeply understanding our customers’ workflows and building experiences that feel tailored, intelligent, and indispensable. Our team is a global group of craftspeople, systems thinkers, and innovators who care deeply about quality, velocity, and impact.

We are seeking a Principal Design Engineer to play a key role in shaping the future of AlphaSense’s product experience. This senior individual‑contributor role will lead through craft, systems thinking, and technical excellence, building AI‑powered experiences that feel tailored, intelligent, and essential to our customers’ workflows. You will 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.

What You’ll Do

• 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.
• Lead technical design discussions, make architectural decisions, and guide cross‑team implementation efforts.
• Advance AlphaSense’s design system as a core piece of product infrastructure—defining scalable patterns, enabling consistency, and accelerating teams building across AI‑native experiences.
• Collaborate closely with product managers, engineers, and other stakeholders to research and evaluate user requirements, translate them into effective designs, and ensure that the final product meets both user and business needs.
• Collaborate with engineering teams during development, advocating for design quality and user experience by championing design fidelity and attention to detail throughout the development lifecycle.

Design Leadership & Team Impact

• Act as a senior leader within the Design team, mentoring designers and engineers, raising the bar for craft, and contributing to a strong, collaborative design culture.
• Serve as connective tissue across design, product, and engineering—helping teams navigate trade‑offs between technical constraints, business goals, and user experience to deliver high‑quality outcomes.

Who You Are

• 12+ years of experience in product design, design/UX/front‑end engineering, design systems, or a related discipline.
• A bachelor’s degree or higher, with preference for degrees in design, computer science, information sciences, psychology, or human‑computer interaction.
• Hands‑on experience with modern front‑end technologies (HTML/CSS, JavaScript/TypeScript, React) and evolving design systems.
• Experience building AI and agentic experiences, and actively leveraging AI to speed up and augment the end‑to‑end design and development process.
• Expertise with modern AI technologies and ability to apply them to design problems (e.g., MCP, Claude Code, Codex, Skills).
• Experience shipping production‑ready experiences and influencing technical and design choices across teams.
• Strong understanding of user‑centered design principles, end‑to‑end customer workflows, and the ability to turn new users into habitual users.
• Excellent communication and collaboration skills with both technical and non‑technical stakeholders.
• Demonstrated experience in project leadership, mentorship, and providing constructive feedback to foster professional growth.
