Design Engineer

Accountabilities

• Architect, design, and ship core product UI features from early concepts and whiteboarding through production-ready implementation.
• Translate complex distributed-system behavior into clear, intuitive interfaces for developers.
• Design interfaces that clearly communicate execution timelines, retries, queues, state, failures, and other system activity.
• Build data-intensive experiences capable of handling large result sets, live updates, filtering, search, charts, and timelines.
• Design and implement robust interface states, including loading, empty, partial, error, single-result, and high-volume scenarios.
• Optimize front-end performance across rendering, data loading, perceived latency, long lists, and interactive experiences.
• Profile and resolve performance bottlenecks, including unnecessary re-renders, rendering costs, and bundle-size issues.
• Maintain a consistent mental model across the UI, SDKs, documentation, and other product surfaces.
• Turn technically complex concepts into simple and visually compelling product experiences.
• Establish and maintain a high visual and interaction-design standard across the product.
• Build reusable design systems in code, including components, interaction patterns, and architectural conventions.
• Develop motion and interaction patterns that communicate state, time, and system dynamics.
• Collaborate directly with engineers and founding team members to shape product and design decisions.
• Bring a strong independent point of view to design discussions and challenge assumptions when appropriate.
• Read API specifications, queries, and backend code to understand technical requirements and system behavior.
• Use AI tools and workflows to accelerate development, solve problems, and independently take features from concept to production.
• Contribute to adjacent product areas where strong developer experience, design, and front-end engineering can create additional impact.
• Help establish scalable patterns that enable other contributors to build consistently on the product.

Requirements:

• Strong production front-end engineering experience with React, TypeScript, modern HTML, and CSS.
• Ability to independently take features from concept and design through implementation, deployment, and release.
• A strong portfolio of shipped work demonstrating both design craft and the ability to build what you design.
• Excellent visual design sensibility and a consistently high bar for product quality.
• Strong information-design skills, particularly the ability to turn large amounts of data into clear and quickly understandable interfaces.
• Experience designing and building data-intensive interfaces involving pagination, virtualization, filtering, search, charts, or similarly large datasets.
• Strong front-end performance expertise, including profiling rendering, optimizing long lists, reducing unnecessary re-renders, and managing bundle size.
• Ability to demonstrate measurable performance improvements where possible.
• Experience using visual storytelling to make complex technical concepts intuitive and accessible.
• Ability to implement motion and interaction design directly in code.
• Experience building scalable design systems through reusable components and coherent interaction patterns.
• Ability to read API specifications, queries, and backend code and understand how they affect front-end experiences.
• Strong autonomy and ownership, with the confidence to make design decisions without requiring extensive direction.
• Ability to collaborate directly with senior technical stakeholders and product leadership.
• Willingness to challenge assumptions and advocate for a strong product and design point of view.
• Practical AI literacy and experience using AI tools to increase productivity and independently unblock development work.
• Experience with developer tools, infrastructure products, or AI products would be advantageous.
• Experience with data visualization, including timelines, traces, graphs, or high-volume time-series data, would be a plus.
• Knowledge of accessibility and keyboard-first interface design would be beneficial.
• Creative development experience with technologies such as Three.js, GLSL shaders, 3D, generative, or game-like web experiences would be advantageous.
• Comfort reaching into backend systems when required to deliver a complete feature.
• Experience deploying and owning serverless applications using platforms such as Cloudflare Workers, Vercel, or similar would be beneficial.
• Understanding of edge runtimes, caching, and cold-start considerations would be a plus.
• Comfortable working as a senior hands-on individual contributor rather than primarily managing a design team.

Benefits:

• Remote-first opportunity in Europe, with the Netherlands among the supported locations.
• Exceptional candidates based remotely in the United States may also be considered.
• Minimal travel, with occasional team offsites.
• High level of autonomy and direct involvement in product and design decisions.
• Opportunity to own major product experiences from initial concept through production.
• Work at the intersection of product design, front-end engineering, developer tools, infrastructure, and AI.
• Opportunity to work on technically sophisticated products where performance, reliability, and clarity are critical.
• Close collaboration with experienced engineers and founding team members.
• Opportunity to establish design systems and patterns that influence the broader product.
• Environment suited to a senior hands-on IC who wants to combine strong design judgment with production-quality engineering.
