Join Assert Labs

We are a team of engineers and researchers with an ambitious mission: to move the world toward error-free software. We're doing this by building tools to autonomously test and analyze code. We are backed by Accel, Guillermo Rauch (Vercel), Thomas Wolf (Hugging Face), David Cramer (Sentry), Charlie Marsh (Astral), and a number of other open source developers, machine learning researchers, and entrepreneurs. If you wish to learn more, read here about our mission and values.

Our Culture

• -We are assembling a lean group of generalists. While we welcome experience, we're primarily looking for creative, curious problem solvers with a keen interest in open-ended, technically challenging problems.
• -We want to work with people who care deeply about the mission of the company and enjoy the work required to achieve it.
• -We work in person in our office in San Francisco. We believe that having a community is critical for learning, growth, and camaraderie. We pay generously for relocation assistance.
• -We invest heavily in our team's growth. We sponsor conference attendance (NeurIPS, ICML, RustConf, PyCon, etc.), run an internal paper reading group, and encourage blogging/publishing research. If there's something that will help you grow as an engineer or researcher, we actively want to support it.
• -We believe in compensating exceptional talent exceptionally well. We benchmark our compensation against the top 90th percentile for each role, and we're committed to working with candidates we're excited about to ensure they are excited too.
• -We have an academic as well as competitive spirit. We enjoy thought exercises, math puzzles, intellectual inquiry, and vigorous debates. Outside of working hours we enjoy playing board games like Chess, Go, and Diplomacy.

Role: Product Engineer

Build user-facing native/web applications, CLIs, and SDKs. We're creating a new category of developer tools that requires intuitive interfaces to complex systems. Our work spans VS Code extensions, web applications, and command-line tools - all working together seamlessly to help developers understand and verify their code. This role offers the opportunity to own significant features end-to-end while pushing the boundaries of what's possible in developer tooling.

Responsibilities

• -Design and build delightful user experiences across IDE extensions, native apps, web apps, and CLI tools that help understand and visualize complex program behavior
• -Own features end-to-end, from UI and system design through to implementation, testing, and deployment
• -Create elegant, maintainable APIs and SDKs that developers love to use
• -Collaborate with machine learning and systems engineers to make design decisions that expose powerful capabilities

Qualifications

• -Track record of shipping polished, full-stack applications with attention to detail and user experience
• -Experience with concurrency, multithreading, and distributed systems design
• -Strong understanding of state management, caching strategies, and data synchronization
• -Experience with TypeScript, React, and modern web technologies (WebAssembly, WebSockets, etc.)
• -Experience with macOS development (Swift, SwiftUI, GCD, etc.)
• -Experience implementing IDE integrations using LSP and DAP for rich development features
• -Background in building high-performance developer tools and CLI applications using systems languages (Rust, Go)
• -Product design capabilities including experience with modern design tools (Figma) and ability to implement sophisticated UI/UX independently

Interview Process

Our interview process is designed to be unusually thorough yet efficient, respecting our time as well as yours. We occasionally accelerate the process or skip steps for candidates.
