.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, AngularJS, 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.

Responsibilities

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 AngularJS code behind clean seams and introduce modern Angular and TypeScript 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

Required Qualifications

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

Preferred Qualifications

Azure DevOps, Git, CI/CD pipelines and experience with OctopusDeploy

Experience with Blazor, SignalR, 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 WinForms 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, AngularJS 1.x, jQuery 1.9.x, jQuery UI 1.11.x, ES5 modules authored as CommonJS wrapped in IIFEs

Back end: C# and .NET, ASP.NET and Web API, SQL Server

Tooling: Webpack v3 on legacy bundles, Azure DevOps, Octopus Deploy, logging and metrics tuned per stack

How success will be measured

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
