Job description

Design-Minded Builder Who Can Own Features End-to-End

We’re looking for a sharp product-minded builder who can take ownership of features from concept through QA — not someone waiting around for tickets.

You’ll work directly with a technical founder across several active products and internal tools. This role is ideal for someone who enjoys building fast, thinking critically, and improving products beyond the original ask.

What This Role Looks Like

You’ll be responsible for taking ideas, features, fixes, and improvements and driving them forward independently.

That means:

• Building the feature
• Testing it thoroughly
• Refining the UX/UI where needed
• Communicating tradeoffs and blockers clearly
• Suggesting better approaches when appropriate

We value people who think like product owners, not task executors.

Responsibilities

• Build and ship features across multiple projects using Lovable and modern web stacks
• QA and validate your own work before handoff
• Improve workflows, UX, and product quality proactivelyDebug, refine, and extend generated code when needed
• Work independently while keeping communication clear and proactive
• Help move projects forward quickly without sacrificing quality

Requirements

• Strong experience with Lovable for rapid feature development and prototyping
• Strong full-stack engineering skills (React, TypeScript, Node.js, Supabase, or similar)
• Ability to work directly in code when overrides, debugging, or refinements are needed
• Strong product intuition and design awareness
• Experience building polished applications end-to-end
• Excellent English communication skills (written and verbal)
• Comfortable managing multiple concurrent projects
• Reliable part-time availability on an ongoing basis

Bonus Points

• Experience working on SaaS or marketing technology products
• Strong UI/UX instincts without requiring detailed design direction
• Experience working closely with founders or fast-moving startup teams
• Ability to identify product gaps and propose thoughtful solutions proactively

What We Value

We care about builders who take pride in their work, think independently, and genuinely care about product quality.

If you’re the type of person who notices what could be better — and fixes it — we’d love to talk.
