• Maintain reliable data flows supporting training, inference, analytics, and AI operations

Infrastructure, Deployment & MLOps

• Containerize AI services using Docker and deploy workloads to Kubernetes or cloud-native environments
• Build and maintain CI/CD pipelines for AI model updates and application releases
• Monitor inference latency, application performance, costs, and model drift using MLflow, Weights & Biases, Prometheus, or custom dashboards
• Support scalable and reliable cloud infrastructure on AWS, GCP, or Azure

Security & Compliance

• Ensure AI systems comply with GDPR, HIPAA, SOC 2, or relevant privacy/security standards
• Implement authentication, access control, rate limiting, and secure API practices
• Protect user data and AI workflows using modern security standards and best practices

Collaboration & Product Development

• Collaborate with product managers, designers, and data scientists to prioritize impactful AI features
• Translate prototypes into production-grade systems with scalable architecture and maintainable code
• Participate in sprint planning, architecture discussions, code reviews, and technical documentation
• Maintain clear documentation to support reproducibility, onboarding, and long-term maintainability

What Makes You a Perfect Fit

• Strong software engineer with deep curiosity around AI/ML systems and emerging technologies
• Comfortable moving quickly from prototype to production-grade deployment
• Analytical and solutions-oriented with strong debugging and optimization skills
• Able to balance performance, scalability, usability, and operational cost
• Collaborative communicator who works effectively across technical and non-technical teams

Required Experience & Skills

• 3+ years of professional software engineering experience with AI/ML exposure
• Strong proficiency in Python and JavaScript/TypeScript
• Experience with AI/ML frameworks such as PyTorch, TensorFlow, LangChain, or Hugging Face
• Experience deploying AI or ML models into production systems
• Strong front-end experience with React, Next.js, or Vue
• Strong SQL skills and experience with cloud data warehouses
• Familiarity with REST APIs, microservices, and distributed systems
• Experience with Docker, CI/CD workflows, and cloud infrastructure

Preferred Experience & Skills

• Experience building and scaling AI-powered SaaS applications
• Strong understanding of embeddings, vector databases, and RAG architectures
• Experience with LLM fine-tuning, evaluation, and prompt optimization
• Familiarity with MLOps tools such as MLflow, Kubeflow, Vertex AI, SageMaker, or Weights & Biases
• Experience with serverless architectures and cost-optimized inference systems
• Background in SaaS, automation platforms, analytics systems, or AI-driven products

What Does a Typical Day Look Like?

A Full-Stack AI Engineer’s day revolves around transforming AI capabilities into scalable, production-ready applications. You will:

• Review and optimize AI model APIs for latency, accuracy, and reliability
• Build front-end interfaces that expose AI-driven functionality to end users
• Maintain and improve data pipelines supporting AI systems and analytics
• Deploy updates through CI/CD workflows and monitor production performance
• Collaborate with product and data science teams on AI feature prioritization
• Debug infrastructure, inference, or workflow issues impacting system performance
• Document architectures, workflows, and deployment processes for maintainability and scaling

In essence: you ensure AI systems move beyond prototypes into secure, scalable, reliable, and impactful production applications.
