About the job
Role Description

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
Strong JavaScript and TypeScript fundamentals and deep experience in at least two of the following: Angular, AngularJS, jQuery with ES5
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
Accessibility standards, responsive design, and cross-browser hardening
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.


Our current environment

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
