What is a full stack AI engineer?

A Full Stack AI Engineer is a professional who develops and deploys artificial intelligence solutions across both the front-end and back-end of applications. They combine expertise in AI and machine learning with software engineering skills, allowing them to build, integrate, and maintain AI-powered features throughout the entire technology stack. Their responsibilities often include designing machine learning models, integrating them with APIs, and ensuring seamless user experiences on web or mobile platforms. Full Stack AI Engineers bridge the gap between data science and software development, enabling scalable and production-ready AI applications.

What are the key skills and qualifications needed to thrive as a full stack AI engineer?

To thrive as a Full Stack AI Engineer, you need strong programming skills (such as Python, JavaScript), understanding of machine learning algorithms, and experience with both front-end and back-end development, often supported by a degree in computer science or related fields. Familiarity with frameworks like TensorFlow or PyTorch, cloud platforms (AWS, Azure, GCP), and containerization tools (Docker, Kubernetes) is typically required. Excellent problem-solving abilities, collaboration, and effective communication are standout soft skills in this role. These skills and qualifications enable the seamless integration of AI models into scalable applications, ensuring innovative and robust solutions.

How do full stack AI engineers typically collaborate with data scientists and front-end developers on AI-driven projects?

Full Stack AI Engineers often serve as the bridge between data scientists, who develop machine learning models, and front-end developers, who build user interfaces. They work closely with data scientists to understand the model requirements and deployment needs, and with front-end teams to ensure seamless integration of AI functionalities into applications. This collaboration requires effective communication skills and a clear understanding of both the technical and user experience aspects. Regular meetings, code reviews, and shared documentation are common practices to facilitate smooth teamwork and successful project outcomes.

Type: Contract
Compensation: $90–$110/hour
Location: Remote
Commitment: 40 hours/week

Role Responsibilities

  • Build and ship full-stack applications, services, and internal tools in Python, Java, Rust, C#, C++, or TypeScript that exercise frontier model capabilities end to end.
  • Integrate pre-release model APIs into working software, including tool interfaces, evaluation harnesses, and telemetry.
  • Diagnose and document model and integration failure modes, translating engineering observations into clear written feedback for the research team.
  • Prototype quickly against shifting requirements, delivering working increments with limited up-front specification.
  • Collaborate with the engineering manager and other engineers to maintain consistency in code quality, architecture, and technical documentation.
  • Work independently and asynchronously to meet deadlines while improving AI model performance.

Qualifications

Must-Have

  • 6+ years of dedicated professional experience building and shipping production software at a recognized, top-tier organization.
  • Deep production experience in at least one of Python, Java, Rust, C#, or C++, plus demonstrated delivery in a second language across a different ecosystem.
  • Hands-on ownership across the stack: backend service and API design, a modern front-end framework (React or equivalent), data modelling, and cloud deployment and operations.
  • Demonstrated ability to onboard onto an unfamiliar codebase and deliver working code quickly with minimal ramp-up.
  • Strong written communication skills and the ability to explain complex technical decisions clearly.
  • Ability to engage reliably for at least 40 hours/week during weekdays.

Compensation & Legal

  • W-2 employment with Cincinnatus LLC.
