Senior Software Engineer (Node + React)£90,000 + Bonus + Benefits
Location: Soho, London
Hybrid: 2 days per week in the office
The OpportunityOur 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 ChallengeThe 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 ForExperience
*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
