Job description

Fetcherr builds responsible AI that transforms market complexity into measurable profit growth. At the core of the company is the Market Model, a proprietary AI-powered model delivering accurate, granular demand predictions with 96% forecast accuracy and real-time decision intelligence for commercial teams. Built on a glass-box architecture, it uses market data, not personal data, with full transparency into logic and outcomes. First deployed in global aviation, the technology is industry-agnostic and scales across volatile markets. Fetcherr delivers a consistent average profit uplift of 7%, with corporate partners including Delta, Virgin Atlantic, WestJet, Viva, and Azul.
We are looking for an MLOps Team Lead to drive the development of an internal machine learning platform for a group of ML teams. This is a hands-on leadership role: you will guide a small team of MLOps engineers that builds the automation and infrastructure powering our research (R&D) workflows and runs our pipelines to production. You will take ownership of end-to-end initiatives and drive the team toward critical infrastructure and model-lifecycle milestones, while staying close enough to the code to set technical direction and raise the bar by example.
You will be responsible for building and maintaining the models and data pipelines behind our data science workflows, ensuring the accuracy, consistency, and efficiency of the data used for training and inference, working across structured and unstructured data from many sources on a large-scale, distributed platform.

What You Will Do

• Lead, mentor, and grow a team of MLOps engineers, owning delivery and technical quality.
• Take end-to-end ownership of infrastructure and pipeline initiatives across the LMM group, from design through production.
• Stay hands-on: contribute to design and code, review work, and set engineering standards.
• Drive the team through critical milestones in ML model-lifecycle and infrastructure ownership.
• Partner with R&D and other stakeholders to translate research needs into robust, scalable systems.
• Help evolve the platform, including our ongoing migration from Dask to Ray.

Requirements:

• BSc or Master's degree in Computer Science, Mathematics, or Engineering.
• At least 5 years of commercial experience in Python.
• At least 3 years of hands-on commercial MLOps experience in production (not side projects).
• Experience managing or leading a team of engineers, with ownership of both people and delivery.
• Hands-on experience owning the ML model lifecycle (training, deployment, monitoring, retraining).
• Experience with pipeline orchestrators such as Dagster or Airflow.
• Experience with a major cloud provider such as GCP, AWS, or Azure.
• Experience with distributed computing systems.
• Experience with Docker.
• Experience with Kubernetes.
• Commercial experience writing and maintaining scalable ML systems.
• Fluent in English, both written and spoken.

NICE TO HAVE

• Experience with Dagster (Advantage).
• Experience with Dask or Ray (Advantage).
• Experience with Spark, including implementing distributed algorithms in Python (Advantage).
• Experience with traditional predictive, forecasting, or pricing-optimization ML systems (Advantage).
• Experience in aviation, demand forecasting, or price optimization (Advantage).
• Good understanding of data structures and algorithms (Advantage).

If you are excited about building impactful AI systems in a high-growth startup environment, and want to help redefine how industries price, forecast, and optimize, we would love to hear from you.
