Senior or Staff Frontend Engineer

Job Title: Senior / Staff Frontend Engineer (Remote, US)
Role Overview
We are partnering with a well-established, global technology-enabled services company that is modernizing how it builds software. Their engineering organization is delivering new customer-facing web and mobile experiences, a unified design system, and AI-powered capabilities across its products, with Engineering, Product, and Design working together end to end.
This is a high-leverage opportunity for a frontend engineer who already works this way. You will spend more time on architecture, technical direction, and production ownership than on writing every line of code yourself. Frontend Engineers here are software engineers first, held to the same bar for design, testing, performance, security, and production quality as everyone else, with added depth in the browser, component architecture, accessibility, and design systems. The team builds in Angular and TypeScript, and strong React or comparable frontend experience is directly relevant. This search covers two levels: Senior (own a frontend domain) and Staff (set frontend architecture strategy across products).
Key Responsibilities
Own the full frontend lifecycle (architecture, implementation, testing, review, and production) while directing implementation and delegating meaningful build work to AI agents
Senior: Own a frontend domain end to end, including its architecture, quality, evolution, production behavior, and the shared capabilities other teams depend on
Senior: Set technical direction within the frontend platform, design patterns that solve real product needs, and establish clear boundaries
Staff: Set frontend architecture strategy across products, defining where shared patterns and platforms create leverage and where teams need flexibility
Staff: Lead the design system as an engineering platform, setting its technical direction, contribution and release model, and adoption strategy
Solve difficult frontend problems in production, leading diagnosis when behavior, performance, or reliability breaks down and staying accountable for what ships, regardless of who or what wrote the code
Own frontend quality and production health, defining how accessibility, performance, reliability, security, and testing are designed into frontend systems
Staff: Create the APIs, tooling, guardrails, documentation, and defaults that make excellent frontend engineering easier for every engineer
Set AI-native engineering practices for frontend teams, defining how agentic work is specified, validated, tested, and reviewed, while keeping review and production judgment human
Partner with Product, Design, QA, and full-stack engineers to bring frontend architecture, browser behavior, accessibility, and platform constraints into decisions early
Raise the engineering bar through mentoring, reviewing consequential changes, and growing engineers into broader ownership
Education & Qualifications
All levels:
Deep frontend engineering experience building substantial applications with Angular, React, or a comparable framework
Strong understanding of component architecture, state and reactive data flows, rendering, APIs, and asynchronous behavior
Experience designing reusable frontend systems other engineers depend on (component API design, tokens, theming, versioning, migrations, backward compatibility)
Ability to set the bar for accessibility, performance, security, and privacy (XSS, authentication and session handling, browser storage, sensitive data exposure, third-party scripts)
Already works AI-first: agentic tools are a primary development surface for planning, implementation, testing, and review, and you remain accountable for what ships
Technical leadership experience, including mentoring and carrying meaningful production and incident responsibility
Senior
Strong browser and web-platform fundamentals (semantic HTML, CSS, DOM and event model, browser APIs, progressive enhancement, cross-browser behavior) and the ability to diagnose issues with profiling and developer tooling
Ability to design and own a frontend testing strategy across unit, component, interaction, visual-regression, and end-to-end levels; experience with Jest, Testing Library, Playwright, Storybook, or similar tooling is preferred
Staff
Deep frontend architecture expertise, having set technical direction for substantial Angular, React, or comparable applications, including module and package boundaries, dependency management, and performance
Depth to lead an Angular + TypeScript platform, with experience transferable across frameworks
Track record of building frontend platforms other teams successfully depend on
Ability to reason about production systems beyond the browser (API and service boundaries, authentication and authorization, observability, failure modes, deployment behavior)
Ability to turn organization-level ambiguity into durable technical direction and build alignment without relying on authority
Experience creating patterns and guardrails that let teams delegate engineering work to AI agents at organizational scale
Preferred Experience
Hands-on Angular expertise
Experience with Storybook or visual-regression tooling
Contributions to a shared component library
Staff: Experience owning a component library or design system consumed outside your own organization
Staff: Contributions to open-source frontend tooling
