About this role
We are looking for a Senior Machine Learning Engineer to join a cross functional team, focussing on growing our product algorithmic recommendations within Just Eat .
Your team will focus on evolving existing machine learning and AI capabilities across the platform, improving those capabilities, and innovating new ones for the future.
As a Senior Engineer you will drive our architecture, write highly scalable and testable code, mentor engineers and challenge our teams to strive for excellence. You will work closely with a large number of teams, both internal and external, with inner-sourced development our standard way of working. Ownership is one of the core engineering principles in our organisation - we write it and we own it. Engineers are expected to take responsibility for their work from discovery to production, ensuring the ongoing reliability and stability of our systems.
Location: Hybrid - 3 days a week from our office & 2 days working from home
Reporting to: Technology Manager
These are some of the key ingredients to the role:
- Collaborate extensively with Data Scientists, Product Managers, and Backend Engineers to bridge the gap between model development and production systems.
- Lead the architectural design of end-to-end ML systems, from data ingestion and training pipelines to real-time inference and monitoring infrastructure.
- Transform innovative data science prototypes into robust, scalable, and secure production software, taking ownership of the "path to production."
- Drive the adoption of MLOps best practices (CI/CD for ML, model versioning, feature stores) to accelerate the feedback loop for Data Scientists.
- Effectively communicate the complexities of ML systems (e.g., latency vs. accuracy trade-offs) to technical and non-technical stakeholders.
- Build and maintain a strong network across the Data and Engineering organizations to ensure ML systems integrate seamlessly with the wider platform.
- Lead projects, mentor peers, and advocate for engineering excellence within the data science domain.
What will you bring to the table?
- Proficiency in Python and a strong understanding of software engineering principles (OO design, patterns, testing) applied to Machine Learning.
- Demonstrable experience designing and operating ML systems in production (not just training models in notebooks), including familiarity with serving patterns (e.g., REST APIs, batch inference, event-driven).
- Experience with orchestration tools (e.g., Airflow, Dagster) and cloud-native ML platforms (e.g., AWS SageMaker, GCP Vertex AI).
- Ability to influence decision-making regarding infrastructure and tooling, balancing "build vs. buy" discussions.
- Strong knowledge of Infrastructure as Code (Terraform) and containerization (Docker/Kubernetes).
- Familiarity with data engineering fundamentals (SQL, distributed data processing) to debug and optimize data flows.
- A proactive mindset to automate manual processes and a passion for improving the developer experience for Data Scientists.
