Job description

Lead Full Stack Engineer
Vauxhall, London
Hybrid - 3 days in the office, 2 days remote

As Zapp enters its next stage of growth, we are hiring a Lead Full Stack Engineer to join our 'Operations Technology' team, which owns vital services that power our critical frontline operations. They ensure smooth operations between our suppliers, distribution centres, Zapp stores and our end-customers.

Zapp is London’s leading premium convenience retail platform.

Zapp partners with some of the world’s leading brands to deliver an exclusive range of hand-picked products 24/7, delivered in minutes.

In a typical backend role, you might never get to interact with your end-customer or witness the impact that your work can have on productivity and efficiency.

• Work closely with our Product and Design team to propose and build the next generation of our operational tooling.

• Become a domain expert in our DC/store/supplier operations.
• Increase the quality of the commits pushed to production.
• Collaborate and work closely with your manager to grow and maintain a mature team of engineers.
• Define critical KPIs to monitor and review performance.
• Be the voice of Engineering in quarterly and annual planning.
• Work with cross-functional teams to understand business requirements and convey them into technical solutions.
• Stay updated on emerging technologies and best practices in backend/frontend development.
• Ensure the reliability, security, and performance of front-end systems through thorough testing and optimisation.

Essential skills:

• 5+ years BE experience withNode.js
• 5+ years working with Typescript
• 3+ years experience building UIs in React
• Comfortable with data design and database architecture
• Experience working with SQL & NoSQL DBs
• Experience of DevOps in AWS or GCP

Desirable skills:

• Serverless architecture
• Working with event driven systems
• Building dashboards and tooling around cloud infrastructure
• GCP experience

Benefits:

• Highly competitive salary & equity package
• Enjoy 25 days of holiday per year (plus all bank holidays)

• Extended sick pay and maternity/paternity leave pay
• Perkbox

• Flexible/hybrid working arrangement (60:40 between office/home)
