Software Developer, DevEx (Stateful Systems)

About the role

We believe independent restaurants deserve the same advantages as big chains without giving up their independence.

Ilir Sela started Slice in his family’s pizzerias, where he saw firsthand what it takes to run a local shop. Now we’re taking everything we’ve learned beyond pizza, to taquerias, delis, burger joints, and other neighborhood staples.

We put technology, marketing, buying power, and support to work for more than 15,000 restaurants, so owners spend less time on admin, marketing, and order management and more time growing their business. They remain independent, but never alone.

We’re growing our team to help bring this next chapter to life. That’s where you come in.

This position is open to applicants across all of the UK, and North Macedonia on a remote basis, with the physical offices located in Belfast - Northern Ireland and Debar, Ohrid, Skopje - North Macedonia.

What You'll Do

As a Software Engineer on the DevEx Stateful Systems team, you'll build the tooling and services that let every engineer at Slice work confidently with our databases, queues, caches, streaming pipelines and data lake. Our first priority is availability, from the systems that let customers order pizza and shops fulfil those orders, through to the reporting used across the business. You'll bring strong backend engineering to that problem, turning expert, manual work into self-service capabilities that product teams actually want to use.

You will:

- Build internal tooling, services and APIs that let engineers provision, change, migrate and troubleshoot their databases, topics and caches safely, without waiting on us.

- Replace manual operational work with automation: upgrades, migrations, access requests, backups and restores.

- Help operate and harden our production data stores and take part in the team's on-call rotation.

- Partner with product engineering teams on schema design, migrations, query performance and ORM usage, bringing the perspective of someone who has done it from the application side.

- Manage infrastructure as code with Terraform and improve CI/CD pipelines using GitHub Actions.

- Improve observability across our stateful systems, instrumenting services and building alerts that teams can act on.

- Use generative AI to help build and maintain internal services, including agentic services.

- Champion best practices around reliability, safe change, security and platform adoption. Slice works on a "you build it, you run it" model, so our job is to give teams the tooling and expertise to run their systems well, not to run them on their behalf.

Our Technology

- PostgreSQL (AWS RDS)

- Python

- Terraform

- AWS

- GitHub & GitHub Actions

- Datadog
