With a 200-year legacy and a shared passion for what’s next, this is the right place to build a fulfilling career.About UsWe 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.About the RoleAs 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.ResponsibilitiesProduct EngineeringBuild and maintain Angular-based interfaces for the core product: integration configuration, transformation building, workflow monitoring, execution results, and audit log viewsOwn features end-to-end — from Figma file through Angular components, Python API endpoints, and production deploymentImplement and extend the component library in close coordination with the Head of Design and Product DesignerBuild high-performance data views: filterable tables, real-time execution output streams, transformation diff views, and audit logsDesign CollaborationTranslate Figma designs into production Angular components with high fidelity — using Figma Dev Mode and design tokens as the contractWork directly with the design team during the design process — flag constraints early, prototype in code when needed, push quality forwardMaintain Storybook as the living documentation for the component libraryAI-Specific FrontendImplement streaming UI patterns for AI-generated transformation outputs — progressive rendering, token-by-token display, interruption and retry handlingBuild interfaces for AI-suggested transformations — multi-step diff views, accept/reject/edit flows, and inline suggestionsDesign and implement feedback mechanisms that capture user corrections and improve AI quality signalsQuality & SecurityWrite comprehensive unit and integration tests; maintain confidence through the CI pipelineOptimize for Core Web Vitals and application performance — lazy loading, OnPush change detection, virtual scrolling for large datasetsApply Angular's built-in security patterns and implement RBAC-aware UI rendering for permission-scoped featuresBuild to WCAG 2.1 AA accessibility standards — enterprise customers have compliance requirementsRequirementsExperience4+ years professional frontend engineeringHas built and shipped features in production SaaS environmentsTechnical SkillsAngular — deep proficiency required: components, services, RxJS, reactive forms, lazy loading, standalone components, Angular CDKTypeScript — strong TypeScript skills; thinks in typesPython — comfortable writing backend API endpoints (FastAPI or similar); full feature ownership across the stackFigma fluency — Dev Mode, components, design tokens; works directly from design files to production codeTesting — Jasmine/Jest for unit tests; Cypress or Playwright for integration and E2EState management — NgRx, Akita, or comparable reactive state patternsActive user of AI coding assistants in daily workflowNice to HaveStreaming UI experience — WebSocket or SSE for real-time data outputData visualization — D3.js, Chart.js, or ngx-charts for financial dashboardsCode editor experience — CodeMirror or Monaco for transformation editing interfacesAngular Material or Kendo UI (Telerik) for data-intensive enterprise UIsMicro-frontend patterns (Module Federation) or Nx monorepo toolingFinancial services UI experience — audit trail views, RBAC display logic, compliance-aware interface patternsWhy Join UsCategory-defining work — AI-native data integration and transformation for financial services doesn't exist yet.
