 Position Summary:

We are looking for a passionate Software Engineer II to help design and build the web-based viewing and collaboration experiences at the heart of Bentley Infrastructure Cloud (BIC). Our team builds the embedded 3D/digital-twin viewer and its surrounding feature modules - used by engineers, owners, and contractors worldwide to review, markup, and collaborate on infrastructure projects (buildings, bridges, roads, rail, and utilities).

You'll work in a modern TypeScript/React codebase built on iTwin.js and Cesium rendering large-scale iModels, Reality Data, and Geospatial Data in the browser, and surfacing that data through rich workflows. This is a high-impact role on a product that is central to how Bentley's users interact with their digital twins every day.

 We will rely on you for the following: 

• Design, build, and ship frontend features for the Bentley Infrastructure Cloud iTwin/iModel Viewer using TypeScript, React, Cesium, and iTwin.js, from requirements through delivery.
• Document features and decisions through clear code, comments, and concise technical write-ups
• Build and maintain micro-frontend (Module Federation) packages in a large pnpm monorepo, balancing shared-package stability with feature velocity
• Write clear, testable, maintainable code with strong unit (Vitest + React Testing Library) and end-to-end (Playwright) coverage.
• Participate in code reviews, PR-based workflows, and agile/Scrum ceremonies, and help uphold our coding standards and architectural boundaries.
• Mentor and support fellow engineers through pairing, reviews, and knowledge sharing.

What You Bring to The Team:

• Graduate or post-graduate degree in computer science, software engineering, or relevant training and/or experience.

• At least 5 years' experience in frontend development with TypeScript, React
• Experience with frontend unit and end-to-end testing (e.g., Jest/Vitest, Playwright), data structures, and OOP.
• Working experience with Scrum and agile methodologies.
• Experience building component-based UIs and consuming REST APIs.
• Familiarity with 3D/graphics in the browser (WebGL, three.js, Cesium, or similar) - directly relevant to iTwin.js viewer work.
• Good verbal and written communication skills.
• This role requires minimal travel.
• Requires sitting or standing at will while performing work on a computer (or any other physical requirements).

What would make you stand out:

• Experience with Azure DevOps, CI/CD, GitHub, GitHub Copilot,  and Git 
• Experience with monorepos and module/micro-frontend architectures
• Exposure to Cesium and iTwin.js  or other digital-twin / BIM / CAD platforms.
• Experience integrating or building AI/Copilot-assisted features 
• Familiarity with WebGL/3D rendering performance in web apps.
