About the Role
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.

Key Responsibilities
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

Required Experience
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

Nice to Have
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

Why This Role?
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
