Become a Key Player as a Staff Frontend Engineer, Systems

You will help build and scale the frontend systems that give engineers real-time observability into high-frequency telemetry, enabling faster and more reliable development. You’ll work closely with backend engineers and other stakeholders to define architecture, APIs, and data formats. This is a Hybrid role (in person twice a week—Mondays and Thursdays—with a full team week every two months); the organization prefers local candidates but may consider relocation assistance or remote from the San Francisco area for the right candidate.

Here’s How You’ll Make an Impact on the Team

• Design and optimize data pipelines that run entirely in the browser (e.g., Web Workers, OPFS, binary data processing)
• Build interactive visualizations for time-series telemetry, FFT frequency analysis, mapping, scatter plots, and other specialized visualizations
• Solve high-performance problems such as bypassing framework render cycles, coordinating worker thread pools, and managing memory for large binary buffers
• Architect composable UI systems that preserve full data fidelity and precision for technical users
• Collaborate across the stack on API design, binary serialization formats, and query semantics for structured data endpoints

Here’s What You’ll Need to Be Successful in This Role

• 7+ years building software for the web with experience pushing browser limits (performance optimization, binary processing, GPU rendering, multi-threading, etc.)
• Strong TypeScript skills and comfort working in a React codebase
• Systems-level intuition (memory layout, thread coordination, caching strategies, data serialization)
• Experience building for correctness under constraint where data fidelity and performance cannot be traded off

Here’s What Else Might Help You Out

• Experience with GPU-accelerated rendering in the browser (WebGL, WebGPU, Canvas 2D optimizations) or large-scale technical visualization (D3, ECharts, custom renderers)
• Hands-on experience with binary data formats (Arrow, Parquet, protobuf, FlatBuffers) or columnar data processing
• Background in Web Workers, SharedArrayBuffer, OPFS, or other browser threading/storage APIs
• Domain experience where data correctness is non-negotiable (aerospace, scientific computing, medical devices, financial systems)
• Experience building custom caching layers, data processing pipelines, rendering engines, or developer tools

Pay Range

$200,000 - $250,000/year
