Headquarters: San Jose, CA URL: https://remoteleverage.com
About the Role
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.
The product already has a functioning MVP and early validation. Your role will be to take it from “working” to production-ready — ensuring it is stable, scalable, secure, and polished enough for a public launch and real-world usage.
This is a hands-on, execution-heavy role with significant ownership and influence over the product’s technical direction.
Responsibilities
You will 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
Requirements
- 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
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.
