About Reacher

Reacher is a YC-backed AI SaaS platform building the operating system for TikTok Shop brands and creators. We’re backed by Y Combinator, Pioneer Fund, Rebel Fund, and key operators. We have years of runway and are scaling fast with some of the biggest brands in the world (UnderArmour, Hanes, Logitech, Goli).

Our vision is to become the Hubspot for creator marketing, powering brands and creators to connect and grow across all commerce platforms. Your work will directly impact users on day 1.

We build with AI, not around it. Our engineering team uses Claude Code and agentic coding tools as our primary development environment.

What You'll Do

• Own and lead product features end-to-end: research, design, implement, test, and ship
• Lead and shape engineering architecture - set standards for code quality, testing, and development practices across the stack
• Mentor and guide other engineers in adopting AI-native workflows, establishing best practices and patterns
• Talk directly to customers and translate vague requirements into polished user experiences
• Design scalable backend systems (Python, FastAPI, PostgreSQL, GCP)
• Build responsive, delightful UIs (React, TypeScript, Tailwind, shadcn/ui)
• Write clean, maintainable, and testable code with minimal oversight
• Drive architectural decisions and engineering processes that maximize AI-assisted development velocity
• Ship fast and learn fast in a high-urgency environment

You're a Fit If

Engineering Foundations

• 2–6 years of professional backend-leaning full-stack experience at a product-first company
• Comfortable building features across the entire stack—from schema design and backend APIs to pixel-perfect frontend
• Care deeply about product, design, and user experience
• Have owned something meaningful end-to-end
• Resourceful and thrive in ambiguous environments

AI-Native Development

• AI coding experience is your most important skill: deep understanding of modern coding tools (specifically Claude Code) and its various modes
• "AI-pilled" when it comes to problem-solving and default workflows
• Strong systems thinking and architectural awareness: direct AI to build while you architect, review, and verify
• Can demonstrate recent AI-native work where AI coding tools were your primary development environment in the last 90 days

Technical Skills We Value

• AI and Agentic Development: Claude Code proficiency, custom commands, MCP integrations, subagent coordination, and prompt engineering
• Backend: Python, FastAPI, PostgreSQL, system design, GCP, API design (REST/GraphQL)
• Frontend: React, TypeScript, Next.js, Tailwind CSS, shadcn/ui, state management, accessibility (WCAG)
• General: Testing frameworks (pytest, Jest, Playwright), product analytics tools (Amplitude, Mixpanel)
