Senior Full Stack AI Engineer

Hiring company: Toptal Headquarters: Remote URL: https://www.toptal.com/ Summary: We are looking for a Senior Full Stack AI Engineer to design, build, and scale production-grade applications powered by generative AI. This role is focused on delivering real products, not just prototypes. The ideal candidate is a strong end-to-end builder who can make sound architectural decisions, integrate AI capabilities into usable systems, and balance fast delivery with long-term maintainability. General Information: This is a senior engineering role for someone who can own product development from architecture through deployment. The role requires strong full stack engineering fundamentals combined with hands-on experience integrating generative AI into production workflows. The right candidate understands how to build scalable backend services, intuitive frontends, and reliable AI-enabled features that serve real users. This person should bring strong product thinking, architectural judgment, and the ability to move independently from requirements to shipped solutions. Tasks and deliverables: • Build end-to-end applications that incorporate generative AI capabilities into real user workflows • Develop scalable backend services, APIs, and integrations using modern engineering practices • Build responsive and maintainable frontend experiences using modern frameworks • Design modular system architectures that support scalability, reliability, and long-term maintainability • Integrate LLMs and other AI tools into production applications with appropriate safeguards and monitoring • Optimize prompt flows, data pipelines, and system interactions for consistency and performance • Translate business requirements into technical solutions and make strong implementation trade-offs • Own features from ideation through development, testing, deployment, and iteration • Reuse and adapt proven solutions where appropriate to accelerate delivery • Continuously improve product quality based on performance data, feedback, and operational learnings Required Experience: • Strong full stack engineering experience, ideally 5+ years • Proficiency in backend development with technologies such as Node.js, Python, or similar • Strong frontend experience with frameworks such as React or comparable modern tools • Experience building and consuming APIs, working with databases, and deploying on cloud platforms • Hands-on experience integrating generative AI into production applications • Practical understanding of prompt engineering and AI system limitations, including failure modes and edge cases • Proven ability to design systems that scale beyond MVP and remain maintainable over time • Strong understanding of software architecture, system design, and engineering best practices • Demonstrated experience shipping multiple production-grade products or platforms • Ability to combine traditional software engineering discipline with modern AI-driven workflows • Experience working independently with strong ownership and product mindset Engagement highlights: • Opportunity to build impactful AI-powered products used in real production environments • High ownership across architecture, implementation, and delivery • Role suited for engineers who enjoy both product thinking and technical depth • Chance to shape scalable systems early and influence long-term engineering quality • Fast-paced environment with a strong emphasis on execution and practical outcomes • Meaningful work at the intersection of full stack engineering and applied AI To apply: https://weworkremotely.com/remote-jobs/toptal-senior-full-stack-ai-engineer
