Senior Frontend & Design Engineer (San Francisco)

Building data-driven AI applications and agents is too complex, even for advanced developers. At Spice AI, were making it simpler by helping developers combine code, data, and AI to build truly intelligent, decision-making systems. Our mission is to make this as easy as creating a modern web page.

We created Spice.ai OSS , a portable AI databasewritten in Rust with a unified SQL interface to query, materialize, and accelerate data from any source, co-located with machine learning models. By bringing compute, data, and models together, Spice OSS enables secure AI-Feedback-Loops (AI-Fly-Wheels) for apps and agents to learn and adapt. We just announced the 1.0-stable release of Spice.ai OSS.

For a deeper dive into the vision, watch Luke's CMU Databases talk on Spice.ai OSS at and read his Materialized View interview at .

We're also building the Spice.ai Cloud Platform , offering managed, cloud-scale Spice.ai OSS along with tools for high-performance SQL, machine learning training, and inference in an interconnected AI backend-as-a-service.

At Spice AI, we hire for MEI: Merit, Excellence, and Intelligence . We're looking for exceptional, top-tier engineers - A players - who are driven to solve hard problems and push the boundaries of what's possible for AI.

As a Senior Frontend & Design Engineer, you will design and build the frontend for the Spice.ai Cloud Platform, creating intuitive interfaces that empower developers to query data, search, inference, and deploy intelligent applications and agents with minimal friction. Your work will directly shape how thousands of developers interact with complex AI systems, turning abstract data and compute concepts into accessible, high-performance tools that accelerate innovation in decision-making applications. This role demands expertise in crafting pixel-perfect UX while integrating robust frontend architectures, ensuring the platform scales to handle real-time AI workloads and delivers measurable value to our users from day one.

• Expertise in design tools, with mastery of Figma for UX, web, and product design.
• Experience designing, implementing, and shipping production frontend systems for developer-focused products, such as tools, platforms, or APIs that target software engineers.
• A track record of strong design, architectural, engineering, and product decisions in frontend and UI/UX contexts.
• Excellent communication skills.
• Ability to ramp up quickly and hit the ground running.
• Ideally, fullstack capabilities with knowledge of databases, data pipelines, search systems, and AI integrations.
• Ideally, experience contributing to open-source projects.
• Experience with cloud-native development and modern web stacks.

• An outstanding contributor in the Spice.ai frontend and design efforts, including the Spice.ai Cloud Platform dashboard, spicerack.org , and developer-facing interfaces.
• Creating, designing, and building intuitive UX for data and AI tools, focusing on web-based experiences that simplify complex workflows for developers.
• Take ownership and drive initiatives for improving the product through frontend innovations, design iterations, and stack optimizations.

• Your first month - ramp up and contribute improvements to the Spice.ai frontend codebase and design prototypes.
• 30-60 days - contribute to weekly Spice.ai platform releases, including UI updates and design refinements.
• 60-90 days - take technical and design ownership of an entire feature area, such as a developer dashboard or AI integration interface.
