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 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 (e.g., Node.js, Python)
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
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

Nice To Haves

You see something broken and fix it. You'd rather move on clarity than wait for certainty.
A fast learner who knows you don't know everything. The AI landscape changes weekly. You're senior enough to know better and curious enough to keep learning anyway.
Direct in a way that makes the work better. You give honest feedback. You'd rather have the hard conversation than blow smoke.
Obsessed with craft. You know genius is in the details. You ship exceptional, not perfect, and you don't put your name on work you wouldn't stand behind.
Built for ownership. You honor commitments, admit mistakes fast, and back your teammates when a decision costs something. No handoffs, no finger-pointing.
All in. You treat clients' businesses like your own. You take the work seriously without taking yourself seriously.
Resourceful when the budget, timeline, or team is tight. Constraints don't slow you down. They sharpen you.
Glad to be in the room with people who care as much as you do. Our teams average fifteen-plus years of experience. We hire people who push each other to do better work.
