Location: Exton/Philadelphia, PA, US – Hybrid (3 days a week, in-office)
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 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.
Responsibilities:
- 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 pnpmmonorepo, 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.
Qualifications:
- 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.
