Associate Director, Platform Engineering
Location: London - x3 days onsite per week
Employment Type: Full-time
Department: Engineering
The Opportunity
As Associate Director, Platform Engineering, you will lead the team responsible for hybrid compute infrastructure, developer platforms, and scientific compute environments that power machine learning, data science, and computational research.
Reporting to the VP of Engineering, you will work closely with your team and senior stakeholders across Engineering, Data Science, and Machine Learning to define and evolve the organisation's platform strategy.
The platform spans on-premises infrastructure and public cloud environments, supporting computational scientist notebooks, model training and serving, internal services, and large-scale data and scientific pipelines.
You will set the technical direction across these areas, build and develop the team responsible for delivering them, and ensure the platform continues to evolve alongside the needs of the organisation.
Day to Day, You Will
- Partner with the VP of Engineering and peers across Engineering, Data Science, and Machine Learning to define and evolve the platform strategy.
- Own the architectural strategy for Kubernetes-based clusters and broader hybrid infrastructure, setting the technical standards and guardrails within which the team designs, builds, and operates.
- Lead and develop the Platform Engineering team, hiring and retaining exceptional engineers, setting clear expectations, and creating the conditions for them to do their best work.
- Own the scientific compute platform, ensuring it reliably and efficiently meets the evolving needs of Machine Learning and Data Science teams.
- Drive the maturity of CI/CD pipelines, internal services, and developer tooling, treating the platform as a product and internal engineers and computational scientists as its customers.
- Establish comprehensive observability and robust disaster recovery and failover strategies across on-premises and cloud environments.
- Own platform security controls, including IAM, secrets management, network policy, and vulnerability management.
- Ensure the platform meets appropriate data governance and security standards when working with sensitive data.
