Software Development Engineer - Backend
South West London

Zapp is looking for Back End Software Development Engineers to join our growing team. You will design and build full-stack experiences for both desktop and handheld devices - creating APIs, and developing backing services to streamline these workflows. 

You’ll own features from inception to deployment and, unlike typical software roles, you'll get hands-on experience by participating in picking, packing, and delivering orders to truly understand the impact of your work on front-line operations. 

Main responsibilities 

• Stock Prediction Optimisation: Striking a balance between overstocking and understocking is crucial. This challenge is amplified by Zapp's unique and diverse product catalogue.
• Supplier Coordination: Managing orders from suppliers with varying levels of technical sophistication—ranging from websites and emails to APIs—requires creating a consistent and reliable ordering experience.
• Handling Unpredictability: Unlike predictable APIs, supplier responses can be erratic. Engineers skilled in managing edge cases will thrive here.
• Order Fulfillment Optimisation: Beyond simple packing, this involves optimising the picking route and prioritising orders efficiently. Think beyond the basics—how can we ensure the best route and prioritise effectively?
• Accurately predicting stock needs: Ensuring we source the right amount to meet demand without waste.

The ideal candidate will have the following

•  Professional experience (5+ years) as a back end developer scaling applications within a fast paced environment.
• Strong Typescript skills and experience with NestJS/NextJS.
• Experience using GCP or AWS.
• Knowledge of GraphQL.

Benefits 

• Competitive salary & equity package
• Enjoy 25 days holiday per year (plus all bank holidays) 
• Private Health Insurance
• Extended sick pay and maternity, paternity leave pay
