About The Position

We’re looking for a Staff Full Stack Engineer to lead the design and delivery of complex, integration-heavy platforms. This role is ideal for an experienced engineer who can define front-end architecture and technical strategy, lead complex UI systems development, and confidently own large parts of the system end-to-end. In this role, you will work as a key technical contributor on a cross-functional team, defining standards and best practices, building scalable systems, and solving complex integration challenges. You’ll build and integrate across channel surfaces including chat, voice, and web, craft front-end experiences for client demos and prototypes, mentor more junior engineers, collaborate closely with senior engineers and leadership, and deliver high-quality work where reliability, performance, and scalability are critical.

Requirements

7+ years of professional software engineering experience, with experience leading complex full-stack initiatives
Deep proficiency in React or Angular with strong JavaScript and TypeScript skills (e.g., React, Angular, Next.js)
Strong experience with state management
Strong command of modern CSS frameworks and build tooling
Strong back-end development and API architecture experience in Python and Node.js
Hands-on experience building channel integrations across chat (e.g., Slack, Teams, SMS), voice (e.g., Twilio, PSTN), and web surfaces
Strong testing practices across unit, integration, and UI testing
Deep expertise in relational and NoSQL databases, caching, and query optimization
Strong experience with microservices architecture, event-driven systems, and message queues
Strong experience with cloud platforms and container orchestration
Strong experience with CI/CD pipelines
Strong experience integrating AI services into production full-stack systems, including LLM APIs, streaming, tool and function calling, multi-step agent flows, and RAG patterns
Ability to build fast, high-fidelity front-end demos and prototypes that communicate technical capability to non-technical audiences
Comfort working closely with design tools and partners to ship polished, accessible UI (e.g., Figma)
Demonstrated leadership and technical mentoring experience across a team or organization
Strong stakeholder communication skills, with the ability to translate technical depth across audiences
Demonstrable, day-to-day usage and expert knowledge of AI-forward tools such as Claude and Cursor
Excellent problem-solving skills and the ability to navigate highly ambiguous technical and business challenges with sound judgment
