We’re looking for a Senior Frontend Engineer to take full ownership of the user interface for our advanced graph visualization platform.

This product visualizes large-scale, dynamic networks that represent complex behavioral and analytical relationships within our systems — helping teams intuitively explore, understand, and act on data.

You’ll lead the evolution of the visualization layer: optimizing performance, improving interactivity, and exploring new rendering techniques to create seamless, high-impact visual experiences.

What You’ll Do

Build

• Design, develop, and maintain interactive graph visualizations capable of handling large-scale, complex data.
• Implement high-performance rendering pipelines leveraging 2D, and GPU-based techniques.
• Collaborate closely with backend and data teams to define efficient data formats and APIs for visualization.

Optimize

• Continuously profile and tune rendering performance for smooth, real-time interaction.
• Ensure scalability and responsiveness across devices and data sizes.
• Apply robust architecture and clean design patterns for long-term maintainability.

Innovate

• Research and evaluate new rendering approaches and visualization techniques for scalability and clarity.
• Prototype next-generation visual experiences that make complex data understandable and actionable.
• Shape the technical direction and standards for visualization development across the organization.

• 5+ years of professional experience in frontend development with JavaScript/TypeScript.
• Strong fundamentals in UI architecture, component design, and state management.
• Proven experience in building data-heavy, interactive interfaces with focus on performance and scalability.
• Strong understanding of canvas rendering, GPU acceleration, and rendering pipelines.
• Solid knowledge of 2D visualization concepts, and how to translate data into interactive experiences.
• Deep understanding of browser performance optimization and memory management.
• Ability to work cross-functionally with designers, data engineers, and product managers.

Preferred Experience

• Familiarity with GPU programming, shaders, or parallel computation concepts.
• Experience with large-scale datasets and designing efficient data transformations for rendering.
• Knowledge of data visualization principles, graph theory, or interaction design.
• Experience with coaxing that last frame-per-second out of browsers.
• Strong sense of visual aesthetics combined with an analytical mindset.

Who You Are

• You’re passionate about performance, clarity, and user experience.
• You enjoy transforming complex data into meaningful, intuitive visuals.
• You’re analytical, creative, and detail-oriented — comfortable working close to the metal when needed.
• You take full ownership of your work, from design to deployment, and thrive in an environment that values experimentation and technical excellence.
• You collaborate naturally and enjoy mentoring others while continuously learning new technologies.

Why Join Us

• Own a core visualization platform that plays a key role in how BioCatch visualizes and explores behavioral intelligence data.
• Tackle complex, high-impact visualization challenges at scale.
• Drive the technical evolution of rendering and visualization strategies across the organization.
• Collaborate with talented engineers and designers who care deeply about innovation, performance, and craft.
• Work in a culture that values curiosity, autonomy, and growth.
