Full-Stack AI Engineer

Job Title: Full-Stack AI Engineer

Position Type: Full-Time, Remote
Working Hours: U.S. client business hours (with flexibility for deployments, experimentation cycles, and sprint schedules)

About the Role

Our client is seeking a Full-Stack AI Engineer to design, build, and deploy AI-powered applications that bridge modern software engineering with applied machine learning. This role focuses on taking AI solutions from prototype to production — ensuring systems are scalable, reliable, secure, and optimized for real-world business impact.

The ideal candidate combines strong full-stack engineering skills with hands-on experience integrating LLMs, machine learning models, vector databases, and AI workflows into production environments. You will work closely with product, engineering, and data teams to build intelligent applications that improve automation, user experience, and operational efficiency.

This is a highly technical, execution-focused role for someone comfortable owning AI systems end-to-end — from infrastructure and APIs to front-end experiences and deployment pipelines.

• Optimize AI inference performance and infrastructure costs across environments

Security & Compliance

• Ensure AI systems comply with GDPR, HIPAA, SOC 2, and other applicable data privacy standards
• Implement secure authentication, access controls, rate limiting, and API security best practices
• Maintain secure handling of sensitive user and business data

Collaboration & Product Development

• Work closely with data scientists to productionize experimental models and prototypes
• Partner with product and engineering teams to scope and prioritize AI-driven features
• Contribute to architecture discussions and technical planning
• Document workflows, APIs, infrastructure, and AI systems for maintainability and reproducibility

What Makes You a Perfect Fit

• Strong engineer with hands-on experience across both software development and applied AI/ML
• Comfortable moving quickly from experimentation to production deployment
• Analytical problem solver who balances scalability, latency, usability, and cost
• Curious and adaptable, constantly exploring emerging AI frameworks, tools, and workflows
• Ownership-driven with the ability to independently execute complex technical initiatives
• Strong communicator capable of collaborating across technical and non-technical teams

Required Experience & Skills

• 3+ years of software engineering experience with exposure to AI/ML systems
• Strong proficiency in Python and JavaScript/TypeScript
• Hands-on experience with AI/ML frameworks such as PyTorch, TensorFlow, Hugging Face, or OpenAI APIs
• Experience building scalable APIs and back-end systems

• Experience deploying machine learning models into production systems
• Strong SQL skills and experience with cloud data warehouses
• Familiarity with Docker, Kubernetes, and CI/CD workflows
• Experience integrating APIs, vector databases, and AI inference services

Ideal Experience & Skills

• Experience building and scaling AI-powered SaaS applications
• Hands-on experience with embeddings, fine-tuning, and RAG pipelines
• Familiarity with MLOps platforms such as MLflow, Kubeflow, Vertex AI, or SageMaker
• Experience with serverless architectures and microservices
• Knowledge of prompt engineering and AI workflow optimization
• Experience optimizing inference latency and AI infrastructure costs
• Familiarity with monitoring model drift, evaluation metrics, and AI observability practices
