Join LeadUp

The Role

You build the majority of the user-facing application. You work from a detailed specification and follow patterns set by the senior developer. AI coding tools are a core part of your workflow.

This is a fast-moving environment. You'll have clear specs, but priorities will shift as the product meets real users. We need someone who treats that as normal.

Why this is different from most junior roles: You're not joining a 50-person engineering team where you'll spend six months on a button. You work directly with the senior developer and the CTO — both hands-on builders. You'll get real code reviews, real architectural conversations, and real mentorship. The product is being built now, with pilot clients coming within months. Your code ships to actual users, fast.

What You'll Do

• Build the full user-facing web application: dashboards, reports, settings, onboarding
• Build admin views: user management, configuration, aggregate data
• Implement supporting systems: notifications, emails, exports
• Write tests against defined error scenarios
• Contribute to database schema design alongside the senior developer and the CTO
• Daily sync with senior developer; PR review on every merge

Required

• 1–3 years of professional development experience (internships and freelance count)
• React (or Next.js) for frontend, Python for backend (FastAPI experience is a strong plus)
• Basic PostgreSQL: can write queries, understands joins, can contribute to schema design
• Active AI coding tool user (Claude Code, Cursor, Copilot) — part of your daily workflow
• Can read a spec and ship features without hand-holding
• Comfortable with changing priorities
• Asks questions when unclear rather than guessing
• Solid written and spoken English

Preferred

• FastAPI experience
• Tailwind CSS, responsive design
• Authentication flows (OAuth, JWT)
• Dashboard or report-style interfaces
• Portfolio or GitHub showing end-to-end projects

Why Join

• You won't guess what to build. Detailed spec. Your creativity goes into quality and speed.
• You'll learn from strong people. Senior developer sets patterns. CTO works hands-on with the team.
• Your work ships fast. Pilot clients within months. Real users, real feedback.
• Ground floor. The product is being built now. If it succeeds, you were there from the beginning.
