Job description

Senior Full Stack Engineer

Location: Remote — (Open to applicants located anywhere around the globe)

Fueled is a leading digital strategy, design, and engineering agency. We are a 300+ person team that has designed and built hundreds of digital products and experiences for brands like Google, Apple, The New York Times, ESPN, Victoria’s Secret, MGM Resorts, Albertsons, and CLEAR.

As a Senior Full Stack Engineer at Fueled, you will architect, build, and scale high-performance web applications from the database layer through to the browser. You'll own end-to-end solutions across the entire stack, designing API contracts and data models in TypeScript and building performant frontends in React and Next.js, all while ensuring every layer works cohesively to deliver premium user experiences. Type safety runs through your work on both sides of the wire, giving you confidence to evolve complex, business-oriented systems without fear.

You'll model relational and non-relational data, craft pixel-perfect accessible interfaces that perform under real-world conditions, and implement effective caching strategies at the edge. Whether you're optimizing a database query, shaping a REST API, or fine-tuning a front-end bundle, you move fluently across the stack. Your work turns ambitious ideas into maintainable, future-ready systems that evolve with client needs, raise the bar for quality and performance, and consistently drive measurable outcomes.

Depending on your experience and project alignment, your work may lean more heavily into either Fueled's Content Solutions or Digital Product practice. On the Content Solutions side, you may focus on headless CMS architecture, enterprise publishing platforms, performance optimization, design systems, accessibility, and SEO-focused front-end experiences. Within Digital Product, your work may center around complex web applications, stateful front-end systems, API and backend architecture, real-time functionality, and end-to-end product feature development across web and mobile ecosystems. Regardless of focus area, engineers at Fueled are expected to move fluidly across the stack and contribute to thoughtful, scalable user experiences.

Intentionally remote, our team thrives in a culture that values flexibility, creativity, and cutting-edge technology. Together, we’re shaping the future of digital experiences.

What you will do:

• Own the end-to-end delivery of key product features, from concept to deployment and beyond. You won't just code tickets; you'll be a crucial voice in shaping the technical approach, making critical architectural decisions, and ensuring what we ship is robust, scalable, and maintainable.
• Architect and build dynamic web experiences that hold up under the demands of real users and real editorial teams, working across the stack to make the right call at every layer.
• Elevate the team's velocity and craft by introducing and socializing tools and practices that raise the technical bar. We expect you to proactively identify bottlenecks, whether in build processes, state management, content modeling, or anywhere else, and implement solutions that make the entire team more effective.
• Bridge the gap between ambitious creative vision and technical reality, proving that high-quality user experience and developer experience are not mutually exclusive. You'll collaborate directly with designers and strategists to challenge assumptions, explore what's possible, and build solutions that are as elegant under the hood as they are for the end-user.

What you will achieve:

• From Day 1, you're shipping a tangible feature for a live client project, building immediate momentum.
• Within 6 months, you'll own and deliver a key feature end-to-end and improve a core performance metric by at least 10%.
• You will enhance team efficiency by creating a reusable component or process that is adopted by your peers.
• By 12 months, you'll have spearheaded a significant project phase from concept to launch, on time and to a high standard.
• Your expertise becomes a multiplier, evidenced by positive client or team feedback on your ability to solve complex challenges.

About you:

• You think in systems and components, not just pages. You get genuine satisfaction from designing a React architecture or a data schema that is as intuitive for the people using it as it is performant for the end-user.
• You're a proactive problem-solver who doesn't wait for perfect requirements. You thrive on digging into ambiguity, asking "why," and prototyping solutions to complex challenges, whether they involve headless architecture, microservices, or data flow.
• You see the "full stack" as a single, interconnected challenge. You're comfortable crafting a polished, dynamic front-end with Next.js and then diving into the back-end logic, API routes, caching strategies, or CMS configuration that makes it all possible.
• You are a natural collaborator and translator, able to explain technical constraints to designers and strategic goals to engineers, ensuring the entire multidisciplinary team is building momentum together.
