Advice for ML mature companies

Factors to consider when determining when to hire the first MLOps Engineer

Lev Udaltsov, an experienced ML Engineer who transitioned into an MLOps Engineer role, offers valuable insights into the factors that organizations should consider when deciding whether to upskill or hire MLOps engineers. His firsthand experience highlights the critical role that MLOps plays in overcoming infrastructure challenges, bridging skill gaps, and achieving long-term ML success.

  • Infrastructure Complexity: The Missing Piece

    Lev’s experience working with both ML Engineers and DevOps professionals underscores the need for a dedicated MLOps role to bridge the gap between these two domains. He emphasizes that while both ML Engineers and DevOps professionals possess valuable expertise, the lack of an MLOps engineer can hinder progress. MLOps engineers bring a unique blend of data science and engineering skills, enabling them to effectively translate research-oriented models into production-ready applications.

  • Team Size and Skillset: Fostering Expertise

    Lev concurs that team size and skillset play a significant role in determining the need for MLOps engineers. He points out that traditional data science teams often lack the operationalization and automation expertise that are essential for successfully deploying and maintaining ML systems. MLOps engineers fill this critical gap, ensuring that ML models are not only developed but also integrated seamlessly into the organization’s infrastructure and processes.

  • Long-term ML Strategy: A Vision-driven Approach

    Lev’s observation that the need for an MLOps engineer depends on the organization’s long-term ML strategy is well-founded. He acknowledges that for organizations heavily focused on research-oriented ML initiatives, the immediate need for an MLOps engineer may not be as apparent. However, as organizations transition towards more production-driven ML applications, having an MLOps engineer becomes increasingly important to ensure the successful deployment and continuous improvement of these systems.

Additional considerations:

  • Cost-effectiveness: Upskilling existing ML engineers may be more cost-effective in the short term, but hiring experienced MLOps engineers can bring immediate expertise and accelerate your organization’s ML journey.

  • Time-to-market: If you need to deploy ML models quickly, hiring experienced MLOps engineers can expedite the process.

  • Retention: Upskilling existing employees can foster loyalty and engagement, while hiring experienced MLOps engineers can bring fresh perspectives and expertise.

Ultimately, the decision to upskill or hire depends on your organization’s specific needs, budget, and timeline. Carefully evaluate these factors to determine the most effective approach to address your ML requirements.
