About Wonder

Wonder is a next-generation studio blending cinematic craft with AI to pioneer a new model of filmmaking. Backed by Atomico, LocalGlobe, Adobe and leaders from OpenAI, DeepMind, and ElevenLabs, we are building the studio of the future.

Since we got started just a year ago, we’ve worked with some of the best artists, studios and brands on cutting edge productions, launched our debut anthology series Beyond the Loop which surpassed 1.5 million views and grown to a team of 30+ people working across London, NYC, SF and LA.

There are three core pillars to Wonder:

• Agency — delivering content for global studios, brands, and artists
• Originals — incubating visionary new directors
• The Wonder App — a marketplace and community at the center of it all

The App is only a few months old, but it’s already home to thousands of creators talking in real time about the latest developments in creative AI. It’s where the AI × creativity conversation is happening: a live community, a showcase of the world’s best work, a jobs marketplace, and a hub for education.

The App is early, fast-moving, and high-impact. Every feature matters.

The Role

We’re looking for a Full Stack Product Engineer to take ownership of the Wonder App and drive its evolution.

You’ll be the engineer responsible for building, improving, and scaling the product end-to-end; working directly with founders, design, and community to shape what we build and how we build it.

You'll own end-to-end engineering across all four pillars of the App: Chat, Showcase, Jobs, and Education. You’ll architect new features, ship fast, and keep quality high as the platform scales. You'll operate with a high degree of autonomy and be expected to bring engineering opinions.

We’re looking for someone with a high sense of agency who is excited by ownership of the entire app experience.

The system you'll own

The Wonder App runs on a non-traditional stack designed for speed and flexibility:

• Frontend: Custom HTML/JavaScript embeds running inside Circle (iframe environment, no build step)
• Backend: Cloudflare Workers acting as an API layer (auth, caching, proxying Circle APIs)
• Infrastructure: Cloudflare R2 + CDN for asset delivery (images, animations)
• Platform: Circle (community layer), Framer (marketing + SEO)

This is not a typical React app. You’ll be working across constrained frontend environments, edge infrastructure, and API design — making performance and UX tradeoffs across the entire system.

What you'll do

• Own the entire application. Take full responsibility for the Wonder App — from architecture decisions to production deployments. You ship, maintain, and improve the system end-to-end.
• Design and build new features. Drive development across Chat, Showcase, Jobs, and Education. Turn ideas into shipped features quickly, without losing quality.
• Build in constrained frontend environments. Develop UI inside iframe-based embeds with no framework or build step. You’ll rely on strong fundamentals in JavaScript, the DOM, and browser behavior.
• Extend the backend and edge layer. Build and evolve Cloudflare Workers that handle API proxying, authentication, and caching. Make decisions about what runs client-side vs at the edge.
• Own performance and reliability. Optimize load times, caching strategies, and API efficiency as usage grows. You are responsible for keeping the app fast and stable.
• Work closely with design, product, and founders. Collaborate heavily with design, brand, and leadership. Translate ideas into clean, shippable implementations.
• Introduce structure as we scale. Improve testing, patterns, and engineering standards over time. Help lay the foundations for future team growth.

What you'll bring

• 3+ years building production web applications. You’ve shipped real products and owned features end-to-end.
• Strong frontend fundamentals. Deep understanding of JavaScript, the DOM, browser APIs, and performance. Comfortable working without heavy frameworks when needed.
• Experience with modern frontend frameworks (React preferred). You bring strong UI engineering instincts and component thinking.
• Backend or edge experience. Experience building APIs, serverless functions, or working with platforms like Cloudflare Workers or GCP.
• System design capability. You can take a problem from idea → architecture → production independently.
• Testing and performance mindset. You care about reliability, clean code, and making things fast.
• Bias for shipping. You move quickly, make pragmatic tradeoffs, and get things live.
• Fluency with AI tooling. You use AI coding tools as a natural part of your workflow. Not as a crutch, but to move faster, reduce boilerplate, and spend more time on the hard problems.
• Comfort with ownership. You’re happy being responsible for a system and making decisions that matter.

You might be a great fit if

• You’ve built and maintained a product largely on your own
• You enjoy working closely with design and founders
• You care about UX polish and performance, not just functionality
• You’re comfortable debugging across frontend, backend, and infrastructure
• You prefer shipping real features over working on abstract systems

Success in 12 months

• The App is stable, fast, and scalable — with systems you understand end-to-end
• A stream of meaningful features has shipped across all product areas
• Engineering standards and patterns are in place to support team growth
• You’re a trusted voice in product and technical decision-making

Why join Wonder

• Own something real. This is your App. Your decisions ship to production and are used by a fast-growing creative community.
• Build at the frontier. Work at the intersection of AI, creativity, and storytelling.
• Shape the team. Clear path toward senior ownership or leadership as we grow.
• Work with exceptional people. Collaborate with founders, creatives, and partners across the leading edge of AI and media.
