Frontend Engineer

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. Type Script 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
• 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
