Front-end Engineering

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 are on a mission to rebuild how financial services firms create, manage, and execute their data integrations and transformations. 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. 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. 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.

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

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

AI-Specific Frontend

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

Quality & Security

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

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; Python — comfortable writing backend API endpoints (FastAPI or similar); Testing — Jasmine/Jest for unit tests; Active user of AI coding assistants in daily workflow

Streaming UI experience — WebSocket or SSE for real-time data output

Data visualization — D3.js, Chart.js, or ngx-charts for financial dashboards

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

Category-defining work — AI-native data integration and transformation for financial services doesn't exist yet. You'll help build it from the ground up.

Foundational team — You'll be among the first in-house hires. Equity is available for select roles. Poland-based team members receive private healthcare (Medicover or Luxmed), Multisport card, home office setup budget, and professional development budget.
