Product Engineer (Node.Js / React / AdTech) – Contract (6+ Months, Extension Likely)
Location: Remote (EU Time Zones)
Contract Length: 6 months – strong potential for long-term extensions
Start: ASAP
Tech Stack: Node.Js, React, APIs, Social/YouTube integrations, AdTech, Creator/UGC discovery
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
