Senior Frontend Engineer, Visualization

Foxglove • San Francisco, CA

5d • Onsite

About The Position

We’re looking for a Frontend Senior Software Engineer who gets excited about solving complex product problems and pushing web technologies to the limit. At Foxglove, we’re building high-performance, deeply interactive tools for robotics and complex data visualization - far beyond typical frontend framework workflows. If you get excited about streaming massive datasets, pushing browser limits, and crafting workflows that surprise people with what’s actually possible in the frontend, this role might be for you.

Requirements

• 4+ years experience in frontend or full stack engineering roles focused on complex product applications
• 1+ years experience working in Autonomous Vehicles (AV), or related Robotics companies
• Strong proficiency in Rust, JavaScript/TypeScript, along with modern frameworks like React
• Deep knowledge of frontend performance optimization, browser internals, and debugging tools
• Experience handling large datasets in the frontend—buffering, streaming, or visualizing complex information
• Familiarity with build tools (e.g., Vite, Webpack, esbuild) and optimizing development pipelines
• Passion for building technical tools with engineers as the primary users
• Excellent written & verbal communication skills
• Deliver high‑quality work efficiently, often in a third of the time most think is possible
• Ability to self motivate and thrive in a fast-paced, small team environment

Nice To Haves

• Experience working close to the metal: WebGL, WASM, or web workers is a plus
• Experience building Electron-based desktop applications
• Experience in 2D or 3D visualization
• C++ experience

Responsibilities

• Architect and build high-performance, dynamic frontend applications that operate on large or real-time datasets
• Design and optimize complex UI workflows that feel snappy, even under heavy computational load
• Collaborate with product and design teams to create polished, intuitive user experiences for engineers and technical users
• Tackle performance bottlenecks across the stack: from JavaScript execution to data transfer and rendering pipelines
• Contribute to core build systems, framework architecture, and overall app reliability
• Explore creative solutions for non-traditional browser-based workflows (think: streaming data, GPU-backed rendering, large-scale interactivity)
• End-to-end ownership over features, working directly with our customers and community to understand requirements
• Expand your knowledge of the robotics and self-driving industries
• Work alongside an experienced team on a cutting edge product

Benefits

• $300 monthly budget towards commuter benefits or building your personal workspace (remote only)
• Competitive equity grant in a Series B company
• Medical, Dental, Vision, and Term Life insurance coverage at 100% for employees and 75% for dependents
• 401(k) matching up to 4%
• 4 weeks vacation, plus holidays and winter break
• All expenses paid company off-sites 2× per year
