Ilir Sela started Slice with the belief that local pizzerias deserve all of the advantages of major franchises without compromising their independence. Starting with his family’s pizzerias, we now empower over tens of thousands of restaurants with the technology, services, and collective power that owners need to better serve their digitally minded customers and build lasting businesses. We’re growing and adding more talent to help fulfil this valuable mission. That’s where you come in.

This position is open to applicants across all of the UK on a remote basis, with the physical office located in Belfast, Northern Ireland.

The Role

By applying your Mobile experience, and software development skills, you will build high quality and intuitive experiences for customer-facing and business-facing apps. You will collaborate with other developers to build scalable solutions that make it easy to build high quality products, and you will work alongside designers and other stakeholders to build exciting new features and refine existing experiences. You will integrate with our custom built in-shop embedded projects. Knowledge of more than one mobile stack as well as an interest in embedded systems is a bonus. 

For this role, we are focusing on hiring at the Senior level, which requires broad professional mobile development experience and a strong track record of leading complex initiatives and delivering broad impact.

The Team

You will be part of our Devices development team that is responsible for all of our customer-facing and business-facing mobile and embedded products. Think pizza ordering apps, Point-of-sale and Kiosk’s to name a few. We believe that consolidating our skills on platform-specific teams leads to a better development environment where you can collaborate, learn from and grow alongside other device experts. Our team brings together talented developers from across the US, UK, and Eastern Europe, each contributing unique perspectives and expertise to drive success.

The Winning Recipe

The core competencies this role calls for:

• Proven experience developing iOS apps with Swift, SwiftUI, Combine and Core Data.

• Embedded systems experience is highly desirable.
• Able to clearly express opinions on product design, while respecting the thoughts and opinions of their peers.
• Adaptable, proactive and results-oriented, capable of delivering solutions efficiently and meeting tight deadlines.
• Proven ability to communicate and collaborate effectively with engineers across all platforms and non-engineering stakeholders alike.
• Comfortable working remotely and collaborating asynchronously with teammates in different timezones and from different backgrounds.
