Senior Frontend Infrastructure Engineer

Description

The company builds software that turns industrial process data into business insight. This is a frontend systems engineering role centered on the React infrastructure, state management, and design system of a complex enterprise product.

You will help create reusable application patterns and the shared frontend foundations that teams use to deliver clear, consistent experiences in data-dense workflows. You care about code that is clean, extensible, and easy to maintain.

Responsibilities

• Lead the ongoing improvement of the frontend system, raising component quality, consistency, usability, and developer experience across the product.
• Build systems that prepare AI-driven development to succeed by codifying practices that agents can easily follow, since AI is changing how interfaces are built.
• Choose and adapt open-source tools such as Zustand, TanStack Query, and StyleX, extending them where needed to suit the company's product, standards, and workflows instead of building from scratch.
• Hold refactors that bring in new patterns or libraries to a very high standard of quality and completeness, since they affect every team that relies on them.
• Work closely with the teams that depend on this infrastructure to roll out changes smoothly.

Requirements

• Expert-level skill in JavaScript, TypeScript, React, and HTML primitives.
• Some exposure to ecosystem libraries such as Zustand, StyleX, or TanStack Query.
• Exceptional frontend engineering with product sense, visual taste, and systems thinking.
• Minimum of 5 years of professional software development experience, including designing, building, and evolving complex systems over several years.
• Experience shipping and maintaining design systems or component libraries in production applications.
• Experience designing, building, or significantly evolving shared frontend systems, such as design systems, component libraries, state management, styling systems, or reusable application frameworks.
• Solid understanding of modern frontend architecture, including state management, server and client data flow, component composition, rendering, and performance.
• Experience building reusable components with careful attention to API design, accessibility, responsiveness, styling, usability, and maintainability.
• Experience leading or significantly contributing to large frontend refactors, migrations, or adoption of new patterns in a production application.
• Good judgment about open-source frontend tools, favoring extension of existing tools over custom solutions.
• Skill at finding root causes of complex defects and performance problems rather than fixing symptoms.
• Ability to write clear technical documentation, conventions, and examples that help engineers adopt shared systems.
• Ability to shape technical direction beyond your own area through design and code reviews, pairing, mentoring, and cross-team work.
• Strong product sense and the ability to work with designers and product teams on consistent experiences across complex workflows.
• Ability to build responsive, scalable web experiences across devices and keep visuals consistent with designers.
• Strong problem-solving and analytical skills with close attention to detail.
• Clear written and verbal communication, and the ability to work in a remote, cross-functional team.
• Familiarity with agile methods and tools such as Scrum or Kanban.
• Ownership and initiative: spot gaps without waiting to be told, decide where to focus, and carry improvements through to completion.
• At Staff level, demonstrated experience setting frontend technical direction or creating shared architectural patterns adopted by multiple engineers or teams.
