Staff Software Developer, Services

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 Challenge to Solve

How do mom-and-pop pizzerias survive and win in a world of big-budget pizza chains and third-party apps? This is the challenge you’ll help solve at Slice.

Local pizzerias already outperform the big chains in offline sales, yet are outsold 20-to-1 online – a gap we’re determined to close.

We operate at the intersection of high stakes and local community: our mission is to level the playing field for small businesses by providing them with the technology and capabilities that rival those of the biggest players.

When a shop partners with Slice, our goal is that it feels “as if they’ve just hired 1,000 people” to support their business.

What You’ll Do

As a Staff Software Developer on our Services team, you will immerse yourself in our ambitious mission and take on a wide range of responsibilities to drive customer impact.

• Build innovative features & services: Design, code, and launch new backend features that help our restaurant partners operate more efficiently and deliver exceptional, seamless experiences to their customers.

Your work will directly enhance real-world interactions between shops and pizza lovers every day.

• Identify game-changing opportunities: Constantly look for asymmetric opportunities where a small technical change can deliver disproportionate value.

You’ll use your creativity and entrepreneurial mindset to find 10x solutions that delight users and give our partners an edge.

• Own projects end-to-end: Take ownership of initiatives from concept through production.

You’ll work closely with product, design, and other teams to define solutions, execute rapidly, and iterate based on feedback.

When you see a problem, you don’t wait - you tackle it.

• Use the best tools for the job: While our primary stack is Python (Flask), we embrace any technology that delivers value.

You might rewrite a microservice from Go to Python, craft a script in Ruby, or leverage a new cloud service – whatever it takes to solve the task at hand in a scalable way.

• Collaborate in a small, agile team: Work alongside a tight-knit team of 5 to 8 backend engineers (across the US, UK, and Europe) who are as passionate about the mission as you are.

Together, you will review code, brainstorm ideas, and push each other to raise the bar while maintaining a fun, supportive atmosphere.

• Ensure quality and performance at scale: Employ best practices in coding, testing, monitoring, and Dev Ops to ensure our services are reliable and performant.

You build it, you own it - from writing unit tests to fine-tuning logging and alerting, you’ll make sure your code runs smoothly in production.

The Winning Recipe

We’re looking for bold, founder-like engineers who aren’t afraid to challenge the status quo and build products that make a real difference.

If you’re an unconventional thinker and a highly productive doer, you’ll feel right at home.

The Extras

Working at Slice comes with a comprehensive set of benefits, but here are some of the unexpected highlights:

• Access to medical, dental, and vision plans
• Flexible working hours
• Generous time off policies
• £200 per annum employee wellbeing allowance
• Market leading maternity and paternity schemes

The ideal candidate has

• Owner’s mindset: You think like a founder.

You take initiative, own problems end-to-end , and move with urgency to deliver results.

Obstacles energize you, and you thrive in a fast-paced, ambiguous startup environment where your decisions drive real impact.

• Proven builder: You have solid experience crafting scalable backend systems in Python (Flask) and working with databases and cloud services.

You’re comfortable diving into monitoring and logging tools to keep systems healthy.

More importantly, you’re technology-agnostic – you quickly pick up new languages or frameworks (Go, Ruby, or whatever is needed) to solve problems effectively.

• Remote-ready collaborator: You excel at working on a distributed team and communicating asynchronously.

You’re comfortable collaborating with teammates across different time zones and backgrounds, and you know how to stay connected and communicative in a remote work setting.

• Product & customer focus: You care deeply about the why behind your code.

You can freely express opinions on product direction and design, always keeping the end-customer and restaurant owner in mind.

At the same time, you respect others’ perspectives and believe the best ideas can come from anywhere.

• Innovative problem solver: You love finding creative solutions to hard problems.

Words like “impossible” or “uncharted” fuel your curiosity.

You seek out those asymmetric win scenarios and aren’t afraid to experiment, adapt, and iterate to achieve a better outcome for users.

If you’ve ever dreamed of building something big, scrappy, and impactful – and you have the skills to back it up – we want to meet you!
