About WUKA
WUKA is a fast-growing consumer brand with established product-market fit across thousands of Tesco stores and Boots locations. While our retail presence is strong, 80% of our business is driven directly through our digital e-commerce infrastructure.
We are expanding our technical capabilities to build a modern, AI-driven data and automation layer. This role will work directly alongside our technology leadership, who brings over 20 years of experience scaling software architectures, including a successful IPO and various venture-backed startups.
Instead of maintaining rigid legacy enterprise platforms, you will have the autonomy to build a next-generation application ecosystem from the ground up. This system will leverage advanced LLM workflows to handle business intelligence, supply chain data orchestration, and automated marketing creative science.
Responsibilities
- Design and deploy internal business intelligence applications and data connectors that interface with our ecommerce systems
- Build backend automation workflows using Node.js, Python, or n8n and data ingestion from ad platforms like Meta, TikTok, and Google.
- Partner with our e-commerce engineers to deploy storefront features and structural updates using the CLI, Next.js, and modern API layers.
- Maintain data tracking integrity by implementing Tag Manager setups and managing Conversion APIs across multi-channel customer journeys.
- Integrate modern AI developer tooling into the daily engineering pipeline to optimize development velocity and code reliability.
Requirements
- 8+ years of professional full-stack engineering experience in a commercial environment.
- Strong proficiency with TypeScript/React, Next.js, Node.js, and backend environments using Python or Ruby on Rails.
- Direct experience integrating LLM APIs, handling structured JSON/XML prompting schemas, and designing multi-agent automation workflows.
- Familiarity with the mechanics of digital commerce
- Understanding of modern web performance metrics, browser tracking constraints, and custom data layers.
- Strong problem-solving skills and the ability to work effectively on-site in a collaborative, fast-paced technical environment.
What We Offer
- Direct mentorship and collaboration with an experienced technology leader.
- Full technical ownership over a modern, AI-integrated software roadmap.
- A practical, execution-focused workspace where your code directly affects business growth and operational scaling.
- Flexible work hours and WFH 1 day per week.
- Private BUPA health plan, company pension.
- Discretionary bonus of up to 5% base salary.
Salary subject to experience - £50K+
