We heard you might be looking for a new opportunity! sunday might be the perfect stop for you. Just in case you haven't heard, sunday is an exciting and thriving FinTech (or FunTech) startup that's changing the way payments are made in restaurants across the world. We are saving millions of people minutes at the end of their meal with the simple scan of a tiny 4x4cm QR code. The coolest thing is we are growing quickly and possibly have the perfect position for you.


Data Engineer

At Sunday we are creating the future of payments, and are looking for experienced data engineers.

With steady growth, millions of requests to handle, a rich and complex business domain and the need for us to have a very high level of availability, you'll find a rewarding and supportive work environment at Sunday.

We are searching for engineers who understand that data is necessary to drive business and product.


We are looking for data engineers

We want to build a data platform that follows the principles of the data mesh paradigm: 

  • domain-oriented decentralization of data ownership and architecture
  • domain-oriented data served as a product
  • self-serve data infrastructure as a platform to enable autonomous, domain-oriented data teams
  • federated governance to enable ecosystems and interoperability

Our data engineering team will build the next generation of analytics. It will fuel our product and internal teams with data, by deploying and scaling our data architecture and tools.

As part of the team, you will create this bridge between business and technical teams and help envision and deploy tools throughout the whole company.

You don't have to be a "fullstack" data engineer to apply to Sunday. If you have an interest for crunching data, development (or both), we are interested in having a discussion. 

Our teams work from the user interface, to the deployment units, owning the whole technology stack. We have a combination of backend, front-end and SRE working collaboratively. So, when needed, it will be expected of you to help your colleagues even if it is not in your area of expertise.


The stack

Our goal is to evolve in a scalable product, able to manage always more payments. 

To this end, we chose this current stack :

  • Storage on GCP
  • PostgreSQL for the persistence of services
  • Firebase for B2C client applications
  • BigQuery for analytics
  • Metabase/Datastudio for Vizualisation tool
  • Datadog for logs
  • PubSub for event stream


What are we looking for ?

If you have already worked on software related to payment, restaurants or POS systems your experience will be of great interest to us.


What do we offer ?

A learning environment with supportive colleagues, a place to grow both technically and as an individual.

A position with full flexibility: full remote, partial or in our Paris office as long as you are available on the CEST schedule.

Competitive salary and stock options.

100% health coverage for you and your children and 4 month equal parental leave policy


While we are offering fully remote opportunities, it is important to know that employees need to be fiscally based in one of the countries we work in to be hired by one of our office: Canada, France, Spain, United Kingdom, United States


Our challenges

Our first challenge is the need to interact with many different POS vendors, each with their specificity.

In addition we obviously must ensure a high level of security, great performance and availability.

Our rapid growth requires a strong focus on data architecture to sustain our delivery capacity while increasing our teams' size, adding new features to the existing software and handling an ever-rising number of users.

And at last, the type of industry we are serving implies a sudden and concentrated traffic peak, meaning we need to have an on-demand scaling capability.
