Jobs

We're building the most advanced browser-based analytics platform in life sciences — where WebAssembly, WebGPU, AI, and scientific computing meet elegant design. The browser is our performance frontier and creative canvas. Join us to push the limits of what the web can do and shape the next generation of interfaces for scientific discovery.

The challenge

Datagrok is both a ready-to-use platform for exploratory data analysis and a foundation for building applications on top of it - think an operating system for life sciences. For UI, we use our own lightweight library, and it has served us really well, unlocking the best performance of interactive visualizations, letting scientists build powerful UIs in a few lines using our JS API, and enabling developers to build rich UI across 50+ plugins.

Now we're taking our UX toolkit and platform experience to the next level. We want to keep the ability to write lightweight, expressive code, and at the same time, we want new frontend developers to be productive on day 1 using popular technologies (maybe React), have dynamically discoverable and configurable components, LLMs to produce the UX based on user prompts, and more.

We're not rewriting the core - we want a technology that would simplify creating UI in apps, plugins, and scripts. And along the way, we'll be creating cool high-performance scientific applications on that stack!

What you'll do

This is an individual contributor role with significant ownership and decision-making authority.

• Enable 90% of polished UIs to be built in pure JavaScript (no HTML or CSS) in lightweight (no-dependency, no-preprocessing) scripts
• Decide whether to evolve our JavaScript API or adopt a framework (React/Vue/etc.), styles (Tailwind), preprocessor (SASS), and/or component library
• Build wrappers for the Datagrok components and expose as widgets using the library of choice
• Develop the component model for widget registration, discovery, and configuration
• Create intuitive UIs for customizing components, binding data, and handling events
• Implement a visual designer with a drag-and-drop palette of dynamically loaded widgets
• Evolve the JavaScript API to be fast, stable, and well-documented
• Build scientific applications using the UX framework
• Build prototypes that showcase platform capabilities and improve UX based on feedback
• Head the front-end development, establish guidelines, mentor, do PRs, etc.

Requirements

Must have

• 5+ years of front-end development (but ability matters more than years)
• Strong JavaScript/TypeScript skills and experience building complex web applications
• Expertise with modern frameworks (React, Vue, or similar)
• Experience building reusable component libraries or design systems
• Proven ability to create polished, intuitive interfaces users love
• Efficient, performant code for data-intensive applications
• Strong problem-solving skills, ability to work independently, and get stuff done quickly

Nice to have

• UX/UI design background or strong aesthetic sense
• Game development experience (demonstrates ability to create engaging, interactive experiences)
• Experience with data visualization libraries and techniques
• Full-stack development skills (Java, Python, R, or other languages)
• Experience with high-performance web applications or scientific computing
• Background in natural sciences, STEM, or scientific software

You're the ideal candidate if you

• Think in systems - building frameworks that empower others to create
• Care deeply about developer experience and elegant architecture
• Thrive in small, autonomous teams where decisions have immediate impact
• Enjoy solving challenging technical problems at the intersection of performance and design
• Get excited about pushing browser capabilities (WebAssembly, WebGPU, WebGL)
• Have a portfolio that makes us say, "wow - we need this person"

We value ability over checkboxes. If you can demonstrate you can deliver - through experience, portfolio, or projects - we want to hear from you.

To apply: include portfolio links, GitHub, or demos showcasing your best UI work.

About Us

We’re building an AI App Builder — a platform that allows anyone to create functional applications through natural interaction with AI. Users describe their ideas — and the system builds the app.

Our small, high-impact team is shaping the foundation of the product: architecture, interface, and AI integration layer.

We’re looking for an experienced engineer with strong leadership skills, technical vision, and hands-on experience in AI-related projects. Someone who can see the full picture — from code to product — and drive the team toward clean, scalable solutions.

(Preference for Russian-speaking engineers with experience in Western AI products.)

Responsibilities

• Lead the design and development of core platform features — from concept to production.
• Define technical architecture for both frontend and backend systems, ensuring scalability and stability.
• Collaborate with AI engineers and product designers to turn ideas into reliable, user-ready functionality.
• Take ownership of engineering quality, process efficiency, and release cadence.
• Mentor and guide other developers; participate in technical decision-making and planning.

• Continuously improve system performance, UX, and developer workflows.

   

Requirements

• 5+ years of professional experience as a Full-Stack Engineer or Tech Lead.

• Practical exposure to AI-driven products (builders, agents, generative apps, etc.) — even up to one year is valuable.
• Demonstrated leadership, ownership, and product vision — not just executing tasks but shaping direction.

• Fluent in building fast-moving products from scratch in startup environments.

   

Nice to Have

• Familiarity with LLM APIs (OpenAI, Anthropic, Mistral, etc.).
• Experience with Supabase, Docker, AWS, Vercel, or Cloudflare AI.

• Background in real-time collaboration, Web IDEs, or AI agent architectures.

   

Why Join Us

• Build at the edge of AI innovation — creating tools that help others build with AI.
• Influence not just the codebase but the entire direction of the product and engineering team.
• Work in a lean, ambitious environment with full autonomy and real impact.
• Become part of the core leadership group shaping a platform designed to redefine how software is created.
