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
They've met candidates who look strong on paper but struggle to explain their reasoning - this role is for someone who can clearly articulate how and why they solve problems.
What They're Looking For
Experience
- Ideally 5+ years of commercial experience
- Experience with NodeJs and ReactJs
- Industry is open (financial services experience may not be the best fit)
Mindset
- Self-starter who can take ownership
- Comfortable leading solutions without formal authority
- Analytical, thoughtful, and curious
- Collaborative rather than siloed
Interview Process
- ~1-hour competency-based interview with the Engineering Director
- ~ Final onsite interview - problem-solving session using a whiteboard
- Focuses on approach, reasoning, and collaboration, not coding syntax
