Senior Full-Stack Engineer, AI-Native

Salary: $101,507 - 150,000 per year Requirements: We are looking for a senior full-stack engineer with genuine AI-native experience, not just familiarity with AI tools. We expect you to have recently shipped production work using Claude Code, Codex, Cursor, or similar tools as your primary development approach. You should be able to show examples from the last 0-6 months where AI tooling helped you deliver substantially faster than a traditional workflow. Strong engineering fundamentals are essential; you must know when AI output is incorrect and understand the systems you build on. You should be comfortable working across the stack, including Python, modern JavaScript/TypeScript, SQL, REST/GraphQL, and cloud deployment. You need a strong bias toward shipping, with a preference for getting a rough version into production over waiting for perfection. We value direct, timely communication, especially when work is blocked. You should be able to start from a simple goal and a short conversation with a stakeholder, then return with a working prototype. Experience with Salesforce APIs, Snowflake, or fintech and lending data models is a plus. Additional bonus experience includes building MCP servers, working on agentic systems, or contributing as part of a small founding team. We care more about what you have shipped recently than formal pedigree or brand-name credentials. Responsibilities: We will have you take prototypes into production quickly, often in days rather than weeks. You will work closely with our Lead AI Architect on architecture, system design, and the ongoing evolution of our AI platform. You will build and launch AI agents that interact with customers through SMS, email, and voice, with clear business impact on lead nurturing, transactions, and retention. You will integrate our systems across Salesforce, Snowflake, Gmail, Zoom, Slack, and internal services. You will own the full delivery lifecycle, including backend development, frontend work, deployment, monitoring, and continuous iteration. You will partner with operations, sales, underwriting, and marketing leaders to turn business needs into shipped product quickly. You will iterate directly in production and improve features after release rather than waiting for a perfect launch. You will be expected to move fast, make decisions, and deliver working solutions with minimal direction.
