About The Position

At BBH, Partnership is more than a form of ownership—it’s our approach to business and relationships. We know that supporting your professional and personal goals is the best way to help our clients and advance our business. We take that responsibility seriously. With a 200-year legacy and a shared passion for what’s next, this is the right place to build a fulfilling career. We are on a mission to rebuild how financial services firms create, manage, and execute their data integrations and transformations. Today that process stretches across multiple teams, tools, and handoffs — slow to build, expensive to maintain, and nearly impossible to change. We collapse it into a single AI-native platform that business users can operate without writing a ticket, while engineering teams retain the governance and security controls they require. We're growing our founding team now. As a Frontend Engineer, you'll own the client-side experience of the platform — the interfaces through which financial services users configure integrations, build and execute transformations, monitor workflows, and review results. Our product's promise is that business users can operate it without writing a ticket. That promise lives or dies in the UI you build. This is a design-collaborative, full-stack-adjacent role. You'll work directly from Figma, own features from Angular component to Python API endpoint, and build data-dense, enterprise-grade interfaces that financial services users trust. The bar for craft is high — our users are experienced, demanding, and will notice if something is ambiguous or slow. Angular is our framework. TypeScript is how we think. Python is how we reach the backend when a feature needs it.

Requirements

4+ years professional frontend engineering
Has built and shipped features in production SaaS environments
Angular — deep proficiency required: components, services, RxJS, reactive forms, lazy loading, standalone components, Angular CDK
TypeScript — strong TypeScript skills; thinks in types
Python — comfortable writing backend API endpoints (FastAPI or similar); full feature ownership across the stack
Figma fluency — Dev Mode, components, design tokens; works directly from design files to production code
Testing — Jasmine/Jest for unit tests; Cypress or Playwright for integration and E2E
State management — NgRx, Akita, or comparable reactive state patterns
Active user of AI coding assistants in daily workflow

Nice To Haves

Streaming UI experience — WebSocket or SSE for real-time data output
Data visualization — D3.js, Chart.js, or ngx-charts for financial dashboards
Code editor experience — CodeMirror or Monaco for transformation editing interfaces
Angular Material or Kendo UI (Telerik) for data-intensive enterprise UIs
Micro-frontend patterns (Module Federation) or Nx monorepo tooling
Financial services UI experience — audit trail views, RBAC display logic, compliance-aware interface patterns

Responsibilities

Build and maintain Angular-based interfaces for the core product: integration configuration, transformation building, workflow monitoring, execution results, and audit log views
Own features end-to-end — from Figma file through Angular components, Python API endpoints, and production deployment
Implement and extend the component library in close coordination with the Head of Design and Product Designer
Build high-performance data views: filterable tables, real-time execution output streams, transformation diff views, and audit logs
Translate Figma designs into production Angular components with high fidelity — using Figma Dev Mode and design tokens as the contract
Work directly with the design team during the design process — flag constraints early, prototype in code when needed, push quality forward
Maintain Storybook as the living documentation for the component library
Implement streaming UI patterns for AI-generated transformation outputs — progressive rendering, token-by-token display, interruption and retry handling
Build interfaces for AI-suggested transformations — multi-step diff views, accept/reject/edit flows, and inline suggestions
Design and implement feedback mechanisms that capture user corrections and improve AI quality signals
Write comprehensive unit and integration tests; maintain confidence through the CI pipeline
Optimize for Core Web Vitals and application performance — lazy loading, OnPush change detection, virtual scrolling for large datasets
Apply Angular's built-in security patterns and implement RBAC-aware UI rendering for permission-scoped features
Build to WCAG 2.1 AA accessibility standards — enterprise customers have compliance requirements
