Job summary

Jobtailor is seeking an experienced frontend engineer to design and implement interfaces for configuring and monitoring scientific workflows. You will build interactive visualizations for large datasets and 3D structures, and optimize rendering performance as data scales.

You will collaborate with backend teams on APIs and data models, ensuring maintainable, reusable components and a strong user-centric design focus across analytics platforms and dashboards.

Qualifications

Experience shipping and maintaining production-grade web applications.
Strong TypeScript and reactive framework fundamentals (React/Vue/Svelte/others), including component design patterns, state management, and testing.
Experience building data-dense and interactive products, such as analytics platforms, scientific software, dev tools, workflow systems, or complex operational dashboards.
Experience profiling performance and memory usage, with observability and maintainability as a priority.
Strong product-driven mindset: you seek to understand the underlying problem and care deeply about usability.

Responsibilities

Build the interfaces for configuring, launching, monitoring, and analyzing scientific research workflows.
Create interactive visualizations of 3D structures, simulation results, and other large, complex scientific datasets.
Profile and optimize rendering performance and memory so data-dense views stay fast as datasets grow.
Maintain a library of reusable, extensible frontend components with clean, well-documented interfaces so the UI stays consistent as the product grows.
Partner with backend engineers on API contracts, data models, and how asynchronous work is handled.
Work with research scientists and product stakeholders to turn their requirements into interfaces that surface real insight.
