Sr. Front-End Technical / Engineering Lead

Role Summary

The Sr. Front-End Technical/Engineering Lead is the senior technical point of accountability for a 6-month, Agile-driven redesign of an enterprise web application. The engineering lead is responsible for establishing Angular architecture standards, overseeing code quality, and leading backend API integration across the application.

This part-time senior role provides architectural guidance to the Angular engineering team, sets coding standards and best practices, and owns the integration with our customer-provided backend APIs into the Angular UI layer — including authentication state handling, session management, and secure routing.

This individual is the bridge between OneSpring’s design/development team and the client’s IT organization.

Key Responsibilities

• Define and enforce Angular architecture standards, module structure, coding conventions, and component design patterns for the engagement

• Lead backend API integration for authentication state handling, session persistence, secure routing, multi-tenant context, and error/loading state management

• Architect a reusable, modular Angular component library to support screens and UI components with minimal code duplication

• Conduct code reviews across all Angular and HTML/CSS deliverables to ensure quality, maintainability, and adherence to technical requirements

• Collaborate directly with our engineering teams to align on API contracts, integration patterns, and technical handoff requirements

• Implement UI-level session management: token handling, route guards, session timeout, and multi-tenant user context

• Establish testing strategy for front-end components; support integration testing and debugging with real client data

• Lead knowledge transfer and code documentation for handoff to the client's IT development team

• Provide technical input to sprint planning, acceptance criteria definition, and backlog refinement

  
  

Required Qualifications

• 7+ years of front-end engineering experience; 4+ years as a technical lead or architect on Angular applications

• Expert-level proficiency in Angular (v14+): component architecture, lazy loading, dependency injection, reactive forms, RxJS, NgRx or equivalent state management

• 5+ years of experience with HTML5, CSS3, and TypeScript/JavaScript in production web applications

• Demonstrated experience integrating REST APIs into Angular applications, including authentication flows (OAuth 2.0, JWT, session tokens)

• Experience implementing UI-level session management, route guards, and access control patterns in Angular

• Strong knowledge of Angular performance optimization: change detection strategy, lazy loading, tree-shaking

• Proficiency with Agile Scrum development and DevOps practices

• Knowledge of WCAG 2.1 AA / Section 508 compliance as it applies to front-end code

• Strong written and verbal communication skills; demonstrated ability to facilitate technical sessions with client IT teams

  
  

Preferred Qualifications

• Experience in consuming and integrating enterprise authentication services (SAML, OIDC, OAuth 2.0)

• Familiarity with Figma design-to-code handoff workflows and component token systems

• Experience with Angular Material, PrimeNG, or similar component libraries

• Background in DevSecOps practices; experience supporting CI/CD pipeline handoff
