Job details

COVID-19 UPDATE: We are continuing to interview, hire, and onboard remotely. All of our engineering staff are working from home following the UK government’s advice. We shipped everyone’s tech gear and office chairs to their homes and we’re working to ensure everyone is comfortable. We’re expanding on our existing remote practices, and holding some fun online events too!

Who We Are is an e-commerce platform and subscription business. We deliver tailor-made dog food to over 150,000 dogs every month. Every single bag we ship is unique — which is no mean feat when you produce 11,000+ per day. We own the whole experience, from our landing page to the customer’s front door. We use Python everywhere we can, including in our factory.

What You'll Do

You’ll work in one of our autonomous squads made up of engineers, product managers, designers, and quality assurance. You’ll collaborate with teams to solve difficult problems across the entire company — from marketing and data to the factory engineers. We’re remote friendly and engineers can take two days a week to work from anywhere.

In this position, you’ll get to:

  • Work with a modern web stack and microservices to deliver features and products
  • Lead best practices ensuring great software engineering and appropriate testing
  • Contribute to the ongoing evolution of the platform architecture
  • Participate in bi-monthly hackdays to build or learn absolutely anything you want
  • Build software in an environment that supports your individual growth
  • Ensure our customers have a healthy and happy dog for life!

We ship early and often, so we push multiple deployments live per day through our CI/CD pipelines. Our local development environments have setup guides and it’s possible to ship something on your very first day. We like to keep the code review process friendly and supportive so everyone can learn and grow. We also make space in our sprints for learning and development time, and hold in-house workshops on new technologies.

What Makes Us Different

We prioritise work-life balance. We have flexible hours (start 7-10 am, finish 4-7 pm) and the office is almost empty at 6pm or earlier every day. If you’re working remotely you’ll have the same schedule. You are never expected to reply to Slack messages outside of your working hours.

Squads are free to choose their technology stack. We primarily use Kubernetes, Python 3, Flask, Celery, and SQLAlchemy for our monolith and microservices. AWS is our main cloud provider and CI/CD is paramount. Any new frontend features are built with Vue.js in collaboration with product designers. We have a design system which is currently evolving into a design components library.

We don’t use algorithm puzzles in the hiring process. After a phone interview with an engineer, you’ll get a short take home test directly related to the work we do everyday. After that, we’ll bring you in for a round of interviews. Usually two and a half hours, during which you’ll speak to two pairs of engineers and our head of engineering with small breaks in between.

You Are Welcome At

You are welcome at no matter what you look like or where you come from. We are actively seeking a diverse pool of applicants, including those from historically marginalised groups. We believe that a diverse company is a powerful company. It’s through our differences that we will innovate and change the world of pet food for good.
