Job description

Remote Leverage, a talent startup based in California, USA, is building and launching a new, independent SaaS platform backed by a proprietary talent dataset, and we're hiring a Senior Full Stack MERN Developer to join as a founding engineer. This is a remote role focused on building a standalone product with external customers, real scale, and long-term ambition — not client work and not internal tooling. About the Product We're developing a proprietary software platform designed to transform how companies discover, evaluate, and hire remote talent at scale.

What You'll Be Responsible For Taking an existing MVP and bringing it to market-ready, production quality Designing and refining backend APIs and data models Improving frontend UX, usability, and performance Ensuring the system is stable, secure, and scalable Identifying and resolving edge cases, bugs, and technical debt Making pragmatic architectural decisions that support long-term growth Working closely with the founder to move fast while maintaining engineering discipline Writing clean, maintainable, well-structured TypeScript Applying a product-minded engineering approach, not just feature delivery Thriving in an environment with ambiguity, iteration, and evolving requirements Must-Have Skills & Experience 5+ years of professional experience as a Full Stack Developer or similar role Strong experience with TypeScript across frontend and backend Solid React experience building production-grade user interfaces Experience building Node.js / Express APIs Experience working with MongoDB in production environments Proven track record of shipping and maintaining real-world SaaS products Ability to move a product from "it works" → reliable, scalable, and usable Strong product-minded engineering mentality Comfortable working without rigid specs and iterating quickly Fluent English, written and verbal Professional, collaborative, and proactive Open to feedback and continuous improvement This Role Is a Great Fit If You Enjoy taking ownership of real products from early stages Like working close to founders and decision-makers Have shipped SaaS products before and know where MVPs tend to break Care deeply about code quality, maintainability, and scalability Want meaningful impact on a product with real market potential Compensation USD 3000 to 4000 per month We value real-world production experience over polished portfolios. If you've built and shipped meaningful software — and can show it — we want to hear from you. #J-18808-Ljbffr
