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
