The Opportunity

Our client are hiring three Senior Software Engineers to join a growing engineering function that builds technology powering large-scale advertising and media platforms.

This is a hands‑on senior role for engineers who enjoy thinking about the “why” , not just the “how”. You’ll help shape technical decisions, guide less experienced engineers, and contribute to building well‑designed, scalable systems used across major advertising campaigns.

The Challenge

The team is looking for engineers who can:

• Provide technical direction and sound judgement
• Think critically about priorities, architecture, trade‑offs, and impact
• Ask the right questions before diving into implementation
• Collaborate effectively and feel comfortable discussing solutions rather than following scripts
