Podsumowanie oferty

Build and evolve a mature enterprise application for exploring and interacting with complex industrial information. Work across the application stack, with a strong frontend focus, using React and TypeScript to handle interconnected data and complex application behavior.

Wymagania

7+ years of professional software development experience.
Strong commercial experience with React and TypeScript, and strong JavaScript fundamentals.
Proven experience building and maintaining large, complex web applications, including interfaces with complex state, business logic, asynchronous behavior, and feature dependencies.
Experience working in large existing codebases and across frontend and backend boundaries, including APIs, data modelling, integrations, or application architecture.
Experience integrating frontend applications with backend services and APIs.
Practical experience with non-trivial structured or interconnected data, such as trees, graphs, matrices, hierarchical, spatial, or multidimensional data.
Ability to explain how data was represented, transformed, and used in an application, and experience with data representation affecting implementation, architecture, or performance.
Strong problem-solving and analytical skills; ability to reason about performance with larger or more complex datasets.
Ability to work independently with incomplete requirements, ask questions, gather information, and move work forward.
Strong collaboration and communication skills.
English at least B2 level.

Nice to have:

Experience with algorithmic or data structure problems, including graph or tree traversal and shortest path problems.
Experience with matrix operations, multidimensional data processing, large datasets, or performance-sensitive data processing.
Experience with diagrams, editors, workflow systems, maps, CAD-like applications, or interfaces based on interconnected data.
Experience with interactive visualization using D3.js, PixiJS, SVG, Canvas, or WebGL.
Stronger commercial backend development experience or experience with .NET / C#.
Understanding of backend concepts including authentication, databases, API design, data modelling, and distributed systems.
Experience with mature products, legacy functionality, complex dependencies, products used by multiple customers or user groups, or working in a product company over a longer period.
Experience with GitLab and CI/CD, or in a fast-changing R&D or product environment.

Obowiązki
