Staff Software Engineer - Full Stack / Python / React

The Staff Software Engineer will be a high-velocity full-stack builder for the new Product Engineering team, predominantly focused on delivering elite frontend interfaces while possessing the backend capability to ship end-to-end features. This is a 100% builder role meant for an engineer who excels at bridging complex data structures with resilient, highly secure user experiences. You will own the implementation of real-time UI components built predominantly using React. You will enforce a clean, feature-domain driven architecture and harden the API integration layer to ensure absolute security and reliability as our products pivot to an agentic future. 

Key Responsibilities

Own features from the database to the browser. While your primary focus is crafting world-class UIs, you will actively write and modify backend services to support user-facing workflows and real-time streaming components.

Design and enforce a clean Angular module-based architecture organized by feature-domains, ensuring the frontend codebase remains scalable, decoupled, and highly maintainable as the product line expands.

Implement and harden enterprise-grade API integrations. Design robust interceptor patterns for request/response handling, custom error capturing, and secure multi-tenant auth/session state management.

Architect real-time asynchronous UI modules using advanced state management libraries to seamlessly handle heavy data feeds, WebSockets, Server-Sent Events (SSE)

Own internationalization (i18n/localization) workflows across screens, and leverage Progressive Web App (PWA) patterns and service workers to optimize offline resilience and caching strategies.

Architect and develop high-concurrency backend services in Python (FastAPI/Django) to handle core business logic and complex workflows

Actively utilize autonomous coding agents to plan, generate, and test front-end and backend code, maintaining high velocity while ensuring code quality through agent-assisted peer reviews.

Own the implementation of secure authorization protocols (JWT, OpenID Connect) to ensure that both humans and AI agents operate within strict permission boundaries

Monitor and optimize API latency and database query performance (PostgreSQL/MS SQL) to support real-time interaction for both web/mobile apps and high-frequency agent calls. 

Experience: 7-8 years of professional full-stack software engineering experience with a stellar track record of shipping production-grade commercial web applications. 

Expert-level proficiency with React and TypeScript as your primary engineering stack. Strong secondary experience with modern React architectures is highly valued.

Deep experience with React module-based architecture, feature-domain organization, and hands-on mastery of modern state management libraries. Strong knowledge of HTTP/API patterns, secure auth/session handling, and advanced interceptor design for resilient request/response processing. 

Practical experience with enterprise UI frameworks, custom component libraries, and localization/internationalization (i18n) workflows. Solid understanding of PWA behavior, service worker lifecycles, and advanced caching mechanics in React applications 

Strong SQL skills (PostgreSQL/MS SQL) and production experience with OAuth2/JWT for secure service-to-service communication. 

Practical, hands-on experience building or modifying backend microservices and APIs (e.g., Python, Node.js, or Java. Python preferred). Comfortable navigating databases, routing logic, and data schemas. 

Demonstrated proficiency in using coding agents to accelerate the SDLC and plan and code complex engineering tasks.
