Profasee builds AI employees for Amazon brands.Our platform, Profasee Ultra, runs a coordinated team of named AI agents that handle PPC, dynamic pricing, demand planning, FBA reimbursements, supply chain ops, catalog audits, and listing health.Sellers replace their agency, their tool stack, and their in-house hires with one system.We have around 120 live customers, a 90-person waitlist, and we're growing fast.Founded by Chad Rubin, who previously built and sold Skubana and Prosper Show.We are a small, product-focused team.We move fast.We expect every engineer to use the best available tools, including AI, to ship excellent work.The roleWe are looking for an AI-native full stack engineer who is strong in TypeScript and knows how to build real production software with the help of AI tools.This is not a wait-for-a-ticket role.You will take ambiguous product goals, use AI tools like Claude Code, Codex, Cursor, or similar systems to move faster, and apply strong engineering judgment when the model gets things wrong.You should be comfortable working across the stack: frontend, backend, APIs, workflows, data models, integrations, QA, debugging, and production stability.What you will doBuild and improve features across the Profasee Ultra TypeScript applicationWork on AI agent workflows that help Amazon brands make decisions and execute workBuild frontend experiences for our agent UIBuild backend services, APIs, workflow logic, and integrationsImprove platform stability, observability, QA coverage, and production reliabilityUse AI coding tools every day to accelerate development,



investigate issues, write tests, refactor, and ship fasterReview AI-generated code critically and make sure it is correct, maintainable, secure, and production-readyTranslate business goals into working software without needing every detail spelled outWhat you bringStrong professional experience building production software with TypeScriptExperience across the full stack: frontend, backend, APIs, databases, and production debuggingStrong React and modern frontend experienceAbility to reason through complex systems and understand upstream and downstream impact before making changesHands‐on experience with AI coding tools such as Claude Code, Codex, ChatGPT, Cursor, or CopilotA clear point of view on how to use AI effectively in software developmentStrong debugging instincts and the ability to verify that something actually works, not just that the code compilesComfort in a fast‐paced, high‐ownership startup environmentStrong time‐zone overlap with the U.S.Nice to haveExperience with agentic AI systems, LLM workflows, tool‐calling, or autonomous agentsExperience with Amazon, e‐commerce, marketplaces, advertising, pricing, inventory,
