49 Senior Fullstack Engineer jobs

About the Project

Our Client is partnering with a US-based tech startup to build a next-generation AI & Web3 indexing platform—a powerful tool designed to help modern enterprises access and leverage decentralized data with speed and intelligence.

We are looking for a Fullstack Engineer with a strong frontend focus to lead the development of the UI and deliver seamless, user-centric experiences.

Why This Role Stands Out

• Work directly with the founding team in the US – fast-paced, transparent, and execution-driven.
• Modern tech stack: Lit, Shoelace, Web Components, Generative AI.
• 100% remote – full flexibility, zero micromanagement.
• Contract-to-hire track – strong performers will have the chance to join the core team.
• Heavily backed product with high interest and recognition in the tech builder community.

This Role is for You If You:

• Are passionate about startups and want to see real impact from your code.
• Have a solid understanding of JavaScript/TypeScript, UI/UX, and a build-to-scale mindset.
• Want to join an early-stage team where your voice matters and your ideas are heard.

Requirements

• 5+ years of fullstack experience, with a strong emphasis on frontend development.
• Hands-on expertise with Lit and Shoelace (non-negotiable).
• Strong knowledge of JavaScript (ES6+), HTML5, CSS3, and modern web development best practices.
• Solid backend experience (any language/framework + database).
• High initiative, self-driven, and comfortable in fast-paced, fully remote environments.
• Excellent communication skills and proficiency with Notion, Linear, Slack, and Zoom.
• Ability to work async across US and European time zones.
• A passion for crafting beautiful, performant, user-friendly interfaces.

Nice-to-Haves

• Experience with cloud services, CI/CD pipelines, or web performance optimization.
• Contributions to open-source or personal project demos are a big plus.
