We are looking for a Senior AI/ML Engineer to join a high-performing AI engineering team building and deploying real-world AI systems used by Fortune 500 customers. You will take technical ownership of critical ML components, lead model development and productionization efforts, and work closely with AI researchers, platform engineers, and product teams to deliver scalable, production-grade AI systems.
This role is intended for experienced AI/ML engineers who have already built and deployed models in production environments and want to operate at the intersection of research-quality AI and real-world systems engineering.
What You’ll Do
Design, build, train, and optimize machine learning and deep learning models for production use
Lead the deployment of ML models into scalable, reliable production systems
Architect training, inference, and evaluation pipelines for structured and unstructured data
Own model performance, reliability, scalability, and lifecycle management
Drive experimentation, model iteration, and performance benchmarking
Implement and maintain high-quality ML codebases primarily in Python
Monitor, debug, and improve live production models
Collaborate with platform, backend, and infrastructure teams on system integration
Contribute to technical direction, architecture decisions, and AI roadmap planning
Mentor junior engineers and support team-level technical excellence
What We’re Looking For
Bachelor’s, Master’s, or PhD in Computer Science, Engineering, Mathematics, or a related field
7+ years of professional experience in AI/ML, data science, or applied machine learning roles
Proven experience deploying ML systems into production environments
Strong understanding of ML fundamentals, evaluation methodologies, and model lifecycle management
Deep hands-on experience with ML frameworks such as PyTorch, TensorFlow, or scikit-learn
Strong proficiency in Python
Experience designing scalable ML systems and pipelines
Ability to operate independently and take technical ownership of complex systems
Strong problem-solving, architecture, and system-design skills
Bonus Points
Experience with deep learning, LLMs, GenAI, or modern AI architectures
Experience building AI systems used by enterprise or large-scale customers
Strong experience with cloud platforms (AWS, GCP, Azure)
MLOps experience (CI/CD for ML, model deployment, monitoring, observability)
Research background, publications, or applied AI innovation projects
Experience leading AI initiatives or mentoring ML engineers
Why This Role Is High-Impact
Work directly with MIT CSAIL–founded leadership
Build AI systems deployed to Fortune 500 customers
Operate at the intersection of cutting-edge AI and real-world production systems

Questions you could be asked
- How do you monitor a model once it's live, and how do you know it needs retraining?
- Walk me through how you've used PyTorch in your day-to-day work.
- What are the limits of TensorFlow that you've run into, and how did you work around them?
- What's a project where you used scikit-learn hands-on?
- How would you decide a model or AI system is ready to ship?
Adapt your resume
- List these exact terms on your resume: ML Ops, PyTorch, TensorFlow, and scikit-learn. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped. This role is judged on the AI system itself, not the tools around it.
