Founding Full Stack Engineer

Company Description

ResX is changing the way people make last-minute plans. Our platform allows diners to exchange in-demand reservations at the hottest spots, solving the frustration of finding or forfeiting a table at the last minute.

The product is already live in New York and London, used by thousands of diners every day, and growing quickly. We’re now hiring our first in-house engineer to help shape the technical direction and build what comes next.

Role Description

We’re looking for a Senior Full-Stack Engineer to join ResX as our first in-house technical lead and founding engineer. The product is already in market and we’re entering the next phase of scaling the platform.

You’ll own the core architecture across mobile and backend, work directly with the founders, and shape the technical roadmap as we scale the product and team. This is a foundational role - you’ll help define how we build, how we ship, and how the engineering team grows.

If you care about building consumer products people actually use, enjoy fast-moving environments, and want your work to have real, visible impact, we'd love to hear from you.

What You’ll Do

• Own and evolve our current architecture across mobile, backend, and infrastructure
• Build new product features and improve existing ones across the full stack
• Make key technical and architectural decisions as we scale the platform and engineering team
• Integrate with 3rd-party services (Stripe, Twilio, Firebase, RevenueCat, etc.)
• Help scale a real-time consumer marketplace handling reservation alerts, submissions, and claims
• Collaborate with our offshore dev team to ensure smooth, high-quality releases
• Work closely with the founders on product strategy and roadmap
• Grow into a technical leadership role as we build our internal engineering team
• Set high standards for code quality, speed, and user experience

Skills That Will Make You Successful

• Full-stack confidence, especially with mobile-focused products
• You’ve worked with TypeScript, React Native, Node, PostgreSQL, AWS, or similar stacks
• You’ve built consumer apps and know what makes a user experience delightful, fast, and smooth
• Start-up instincts: you’ve been at early-stage companies or worked closely with founders and know how to prioritize and move fast without cutting corners
• You’ve mentored others or led projects and are ready to grow into a technical leadership role
• You know how to translate between technical and non-technical teams, and how to give and receive feedback well
