.NET Web UI Engineer​/Architect

We support mission-critical, data-heavy web applications on a primarily C# and .NET back end. You will be the hands‑on architect for a mixed front end that spans Angular, Angular

JS, and jQuery. Your focus: keep today’s UI stable and fast while leading an incremental, low-risk migration to a modern, testable, observable front end that integrates cleanly with .NET services and middleware.

• Own front-end architecture and a multi-year roadmap aligned to business priorities
• Define standards for state, events, data access, error handling, accessibility, security, and performance and drive adoption across teams
• Encapsulate legacy ES5 and jQuery modules and Angular
  
  JS code behind clean seams and introduce modern Angular and Type Script where it adds clear value
• Improve performance and UX on table-centric workflows including search, filter, sort, paging, export, and near-real-time updates
• Establish pragmatic testing and observability per stack and reduce production defects and time-to-recover
• Partner with product and back-end engineering to sequence increments, de-risk changes, and ship reliably

• Bachelor’s degree in Computer Science, Software Engineering, or related field or equivalent practical experience.
• Five or more years building and shipping front-end features in production with measurable outcomes
• Proven success modernizing legacy front ends incrementally without business disruption
• Solid .NET integration skills including RESTful APIs, OpenAPI, authentication and authorization, caching, middleware, and CI/CD
• Excellent debugging across DOM, events, async flows, data grids, and performance along with clear written and verbal communication

• Azure Dev Ops, Git, CI/CD pipelines and experience with Octopus Deploy
• Experience with Blazor, Signal
  
  R, gRPC‑Web, Web Components, module federation, or micro-frontends
• Financial or trading UI experience and data-heavy screens
• Exposure to desktop UI stacks such as Win Forms or WPF
• Experience with modern AI tools or agentic AI systems. Familiarity with integrating AI capabilities into applications, experimenting with autonomous or semi‑autonomous agents, or leveraging AI to enhance developer productivity is considered beneficial but not required.
• Front end:
  Angular, Angular
  
  JS 1.x, jQuery 1.9.x, jQuery UI 1.11.x, ES5 modules authored as Common
  
  JS wrapped in IIFEs
• Back end: C# and .NET, ASP.NET and Web API, SQL Server
• Tooling:
  Webpack v3 on legacy bundles, Azure Dev Ops, Octopus Deploy, logging and metrics tuned per stack

• Fewer front-end incidents and faster recovery on critical paths
• Performance and accessibility improvements on key screens
• Clearer module boundaries, reduced global coupling, and faster onboarding
• Delivery of modernization milestones with minimal disruption
