Senior Full Stack AI Engineer

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
