As part of our engineering team, you’ll shape the platforms and tools that drive high-impact research - designing systems that scale, accelerate discovery and support innovation across the firm.

Take the next step in your career.

The role

The Storage Engineering team manages hundreds of petabytes across VAST, PowerScale, ECS, Rubrik, Alletra, Pure and a custom Tier Zero platform. The current operational tooling is a patchwork of GitOps workflows and Jenkins pipelines. We're replacing it with a custom-built central automation and reporting engine backed by CockroachDB.

We are hiring a Python Platform Engineer on a contract basis to deliver key components of the platform alongside two other senior Platform Developers and the existing Storage Engineering team. This is a senior individual contributor role focused on hands-on delivery. You will write code every day, contributing high-quality engineering work that meets the team's standards and supports the platform's long-term architecture.

Key responsibilities of the role include:

• Designing and building the central automation and reporting platform in Python
• Building a custom data orchestration engine to copy, move and sync data across platforms, sites and storage tiers
• Delivering world-class self-service tooling for non-technical users
• Implementing a tiered storage strategy to maximise GPU farm efficiency and minimise storage cost
• Building proactive monitoring, health checking and operational dashboards
• Following established coding standards, participating in code reviews, and maintaining CI/CD quality gates and infrastructure-as-code discipline

Who are we looking for?

The ideal candidate will have the following skills and experience:

• Great Python experience, with experience designing large codebases rather than scripting
• Significant experience designing CI/CD pipelines beyond basic Jenkins
• Proven ability to design modular, maintainable systems with clean APIs and contracts
• Strong testing discipline across unit, integration and end-to-end testing
• Excellent communication skills, with the ability to collaborate effectively across teams

The following are desirable but not essential:

• Experience with Go and/or Rust
• CockroachDB or similar distributed SQL databases
• HPC or storage domain knowledge
• Workflow orchestration tools such as Temporal, Airflow or Prefect
• Data movement tooling at scale
• Front-end development experience with frameworks such as React

G-Research is committed to cultivating and preserving an inclusive work environment. We are an ideas-driven business and we place great value on diversity of experience and opinions.
