What will I be doing?

This is a hands‑on early‑career role for someone with a Computer Science degree, a year or two of commercial experience, and a genuine interest in AI and automation. You'll work closely with our People and Finance teams to identify where AI can make the biggest impact – then build the tools to make it happen. You won’t be writing code in isolation. You’ll own solutions from initial idea through to live, AI-powered production systems, with mentorship and support from a technically strong team around you.

  • Build AI workflows - design, develop, and deploy automation using modern LLMs (Anthropic, Gemini) that genuinely transform how our internal teams work
  • Connect ecosystems - integrate AI capabilities into the tools our teams use every day (Workday, Greenhouse, Slack, Jira, Google Workspace) via APIs and modern integration tooling
  • Collaborate with users - partner directly with stakeholders in People and Finance to understand real problems, build prototype solutions, and iterate on feedback
  • Champion responsible AI - act as a go‑to resource for your colleagues, helping them use AI effectively, safely, and with a clear understanding of data privacy implications

About You

You’ll have:

  • A degree in Computer Science or a closely related technical field
  • 1-2 years of commercial experience in software development, systems engineering, or a technical role
  • Comfort connecting systems and manipulating data via REST APIs
  • Hands-on experimentation with LLM APIs (Anthropic, OpenAI, Gemini) – a side project, a university project, or something you built because you wanted to
  • A foundational understanding of data privacy, security, and responsible AI practices

You’re someone who:

  • Enjoys talking to non-technical stakeholders and translating their needs into working solutions
  • Is genuinely interested in how People and Finance operations work – and wants to make them better
  • Takes ownership, asks good questions, and doesn’t wait to be told what to build next
