We're looking for a highly experienced Product Engineer to help build a next-generation AdTech platform, supporting categories such as beauty, lifestyle, UGC, and topic-based recommendations for a Euro Retail and Marketing powerhouse.

This contract role sits inside a fast-moving, cross-functional product team building internal tools and white-labelled solutions used across wider business units. You'll be responsible for scoping, designing, and developing features end-to-end — from backend services to polished, user-friendly front-end experiences.

This is a hands-on build role, perfect for an engineer with strong product instincts and experience delivering consumer-facing or AdTech-driven discovery systems.

• Product Engineering & Feature Ownership
  • Build and evolve a creator discovery solution end-to-end using Node.js and React
  • Own product features from concept → prototype → implementation → iteration
  • Work closely with product managers, data teams, and internal partners to define requirements
  • Rapidly test, validate, and iterate on user workflows and ranking experiences
• API & Platform Integrations
  • Integrate with social-platform APIs (e.g., YouTube Data API, Instagram, TikTok, Pinterest)
  • Develop services to ingest, enrich, and structure creator data (categories, topics, UGC signals, relevance scoring)
  • Optimise ingestion and discovery pipelines for performance and scale
• AdTech & Recommendation Work
  • Build components that support advertising partners, sponsorship matching, and creator-brand fit
  • Implement logic for topic / category classification, recommendation ranking, and metadata structuring
  • Work on internal tools and white-label solutions used by cross-functional teams
• Backend & Frontend Engineering
  • Build scalable backend services in Node.js (REST, GraphQL, event-driven services)
  • Develop polished UIs in React, ensuring high usability and clarity for internal teams
  • Ensure strong code quality, automated testing, and reliable CI / CD
• Collaboration & Delivery
  • Partner closely with engineering leads, PMs, data scientists, and marketing / AdTech teams
  • Operate in a rapid, iterative environment with short feedback loops
  • Participate in architectural decisions and contribute to long-term platform direction
  • Support a healthy engineering culture focused on velocity, clarity, and product impact

• 5+ years as a product-focused engineer
• Strong hands-on experience with Node.js and React
• Experience integrating with social media APIs (YouTube essential; Instagram / TikTok / Pinterest a plus)
• Experience in AdTech, marketing tech, creator platforms, or discovery / recommendation systems
• Experience building internal tools, dashboards, or white-label solutions
• Strong product mindset — comfortable owning features, making trade-offs, and shipping iteratively
• Ability to translate ambiguous ideas into clear technical plans
• Strong communication, stakeholder alignment, and cross-functional collaboration

• Experience with video / content metadata (categories, beauty, topics, "lookalike" discovery)
• Understanding of ranking, scoring, or classification models
• Background with UGC / creator ecosystems (YouTube creators, UGC workflows, performance marketing)
• Experience with event-driven microservices or data pipelines
• GraphQL experience
• Experience in high-scale consumer-facing platforms

• High-impact greenfield project
• Central to the business' advertising & creator strategy
• Autonomy to shape the product and tech direction
• Flexible remote contract with extensions very likely
