Senior Full-Stack Developer (Node.js, Fastify, React) - Canada

Senior Full-Stack Developer

Are you a hunter who thrives on building robust, high-performance web applications? Do you have a passion for clean code and want to take ownership of critical features from concept to deployment? We're looking for a Senior Full-Stack Developer who's fluent in Node.js, Fastify, and React - and ready to take the lead on critical builds. You'll be hands-on in the codebase, help shape our architecture, and guide junior developers as we scale. STARTUP REALISTS NEEDED. This is a true 0-1 opportunity with pre-seed compensation but enormous upside potential. We're looking for someone who understands the early-stage journey and values equity + career growth over initial salary. As a 100% remote role, you'll enjoy location freedom while building something that could transform an industry. If you want to wear multiple hats, have outsized impact, and potentially see your contributions turn into significant rewards as we scale - this is your opportunity.

What You'll Do :

• Own key features end-to-end : architecture, development, testing, and deployment.
• Develop fast, scalable APIs using Node.js with Fastify.
• Build clean, responsive UIs in React (Next.js experience is a plus).
• Help scope and estimate tasks for sprints, and contribute to technical planning.
• Mentor junior developers and lead code reviews to maintain quality standards.
• Collaborate with product and design teams to turn requirements into technical solutions.
• Optimize application performance and ensure scalability as user base grows.
