Senior Full-Stack Engineer (Heavy Frontend)
Location: Remote (UK or Europe - preference for London or Stockholm)
Contract Duration: 6 Months (Start Date: ASAP)
We are looking for a highly skilled Senior Full-Stack Engineer experienced in product based industries to join a globally recognized tech company for a 6-month contract.
You will be joining a brand-new, specialized team currently in a discovery/MVP phase. This team is on a mission to manage data contracts at the code level, drastically improving overall data quality and preventing data incidents to support core personalization platforms and key stakeholders.
If you are an experienced engineer who thrives in platform-driven environments rather than just standard feature development, this is an incredible opportunity to make a massive impact from day one.
The Role
This is a senior-level position intended to double the capacity of a lean, high-performing team. Your day-to-day will be weighted heavily toward frontend architecture, with foundational backend and data engineering responsibilities.
Role Split: ~60-70% Frontend / 30-40% Backend & Data.
Project Focus: Platform engineering and infrastructure work over strictly feature-based UI development.
Impact: Building the MVP to manage code-level data contracts, ensuring high-fidelity data pipelines for massive-scale personalization systems.
Required Skills & Experience
Deep JavaScript Expertise: You must have advanced JavaScript engineering skills, as this is the primary technical requirement for the team.
Platform Experience: A proven track record of working on platform engineering or developer-tooling projects rather than purely consumer-facing features.
Cloud Infrastructure: Familiarity with modern cloud infrastructure (GCP experience is a bonus, but general cloud expertise is highly valued).
AI Tools: Comfortable utilizing modern AI coding tools to accelerate development.
Nice-to-Haves: Experience with Java and a foundational understanding of data engineering principles or data quality systems.
