Job DescriptionJob Description

Senior AI/ML/GenAI Engineer $120/hr | Remote | 6-Month Contract

Are you passionate about building next- AI applications that solve real-world business problems? Join a high-impact digital innovation team as a Senior AI/ML/GenAI Engineer, where you'll help shape intelligent systems using large models (LLMs), agentic AI, and scalable ML architectures. This is a fully remote, contract position starting July 28, 2025, offering $120/hr and the opportunity to work on cutting-edge AI solutions at enterprise scale.

What You'll Do:

• Design and deploy advanced machine learning and generative AI models, including agentic systems and intelligent assistants.
• Optimize LLM performance and inference speeds for real-world scalability.
• Engineer prompts and fine-tune foundation models using domain-specific datasets.
• Implement safety mechanisms and AI guardrails to ensure responsible model outputs.
• Build algorithms to personalize content and decode user intent.
• Architect CI/CD data pipelines for robust, secure ML operations.
• Collaborate across teams to translate business goals into production-grade AI tools.

What Were Looking For:

• 5+ years of ML or AI engineering experience, including hands-on work with LLMs and GenAI frameworks.
• Strong skills in Python, Golang, R, or Java; familiarity with TensorFlow, PyTorch, and related ML libraries.
• Experience with tools like LangChain, CrewAI, and NVIDIA NeMo Guardrails.
• Solid understanding of AI security best practices (e.g., prompt injection protection, compliance standards).
• Proficiency with SQL and both relational and NoSQL data systems.
• Ability to work independently and proactively in a remote setting.

Bonus Points For:

• Experience deploying deep learning systems at scale.
• Knowledge of quantization, model distillation, or semantic vector search.
• Hands-on work with RAG pipelines and personalization strategies.

Why This Role?

Youll be at the forefront of building intelligent systems that power data-driven marketing solutions. This role is implementation-focused with high ownership, strong collaboration, and the chance to directly influence user-facing AI tools in a highly agile team environment.
