What You’ll Do

  • Lead the design and deployment of end-to-end ML systems for enterprise applications, from experimentation to production.
  • Apply large language models (LLMs) effectively by:
  • Fine-tuning and evaluating domain-specific models
  • Developing robust prompt engineering and orchestration strategies
  • Optimizing inference pipelines for latency, throughput, and cost efficiency
  • Write production-quality software with strong engineering rigor, including clean APIs and reliable systems, while collaborating closely with product engineers.
  • Build high-reliability ML infrastructure, including training pipelines, model registries, observability, and CI/CD for ML.
  • Ensure ML solutions meet enterprise standards for security, compliance, data privacy (e.g., SOC2, GDPR), explainability, and auditability.
  • Develop evaluation and monitoring frameworks to measure accuracy, fairness, robustness, and drift in deployed models.
  • Partner with product and GTM teams to identify high-value enterprise use cases for ML and translate them into scalable solutions.
  • Collaborate directly with customer-facing teams to deliver high-impact enterprise projects.
  • Mentor engineers and raise the bar for technical excellence across the organization.
  • Influence technical strategy and help define the company’s long-term AI roadmap.


Who You’ll Be

  • An experienced Python developer with strong knowledge of data structures, algorithms, and CI/CD pipelines.
  • A Machine Learning professional skilled in data wrangling (SQL, pandas, NumPy), supervised and unsupervised learning, model evaluation, and feature engineering.
  • Knowledgeable in Deep Learning frameworks such as PyTorch, with experience in neural networks and NLP models; exposure to generative and multi-modal models is a plus.
  • Experienced in MLOps, including model serving, orchestration (Kubernetes), and experiment tracking, with the ability to design and deliver large-scale ML systems focused on cost optimization and reproducibility.
  • Equipped with a solid foundation in linear algebra, probability, statistics, and calculus.
  • An effective communicator who can translate technical concepts into clear business value and collaborate with non-technical stakeholders.
  • A mentor and leader who provides guidance through code reviews, architectural decisions, and technical direction.
