Platform Engineer – Global AI & Data Platform
Loc: Global Platform Team, HeadFirst x Impellam Group
Enable scalable engineering workflows across our global AI and data platform.
About the Role
Are you a Platform Engineer passionate about building scalable internal platforms, improving developer experience (DX), and driving automation and standardisation? Do you thrive in modern cloud-native environments where CI/CD, observability, and self-service engineering are central to platform strategy?
We’re looking for a Platform Engineer to join the Global Platform Team at HeadFirst x Impellam Group. In this role, you’ll design, build, and evolve the platform capabilities that enable teams to efficiently develop, deploy, and operate workloads across our Headless Data Architecture (HDA) and Custom Apps Infrastructure (CA).
Your Impact
As a Platform Engineer, you’ll play a key role in shaping the engineering foundations behind our global Workforce-as-a-Service (WaaS) platform. You’ll operate at the intersection of cloud infrastructure, platform engineering, and developer enablement, ensuring teams can scale workloads without deep infrastructure expertise.
Your contributions will directly support:
- Headless Data Architecture (HDA) – A modular, API-first platform built on Azure and Databricks, enabling data-driven applications.
- Custom Apps Infrastructure (CA) – Powering integrations, applications, and operational workflows across the organisation.
- Reusable engineering standards – Designing golden paths for:
- CI/CD, deployment workflows
- Observability (logging, metrics, tracing)
- Infrastructure provisioning
- Developer self-service – Reducing friction in build, test, and deployment while maintaining consistency and scalability.
- Cross-functional collaboration – Working closely with Cloud Engineers, Data Engineers, AIOps Engineers, and development teams to simplify operations and enhance DX.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
