The role
At Mercadona Tech, the innovative spin-off of Mercadona dedicated to transforming the online shopping experience for supermarket products, we are looking for an SRE to join our Tech Hub in Valencia.
In the context of a digital product project, we understand that the true value lies in ensuring our customers are as satisfied as possible with our service, and that is only possible thanks to the products developed by our colleagues from other verticals.
As part of the Platform team, your role will be key to guaranteeing the stability, security, and efficiency of the technological ecosystem. Your mission will be to support product teams from the technical base, facilitating their autonomy and delivery speed.
What you'll do
Provision and maintain the infrastructure necessary for the optimal functioning of our applications.
Manage observability tools that allow teams to monitor and diagnose their services in real time.
Automate deployment processes, ensuring speed and reliability in every delivery.
Develop proprietary solutions with a product focus, adapted to the real needs of the teams.
Foster technical autonomy of the development teams, offering self-managed and well-documented platforms.
Apply Extreme Programming practices to guarantee quality, collaboration, and continuous improvement.
Actively participate in the day-to-day of the verticals, collaborating closely with other product teams.
Professional development at Mercadona Tech
In 1 month
You will get to know everything about the Mercadona Tech project that the public does not see. You will go to our Colmena (the warehouse where we prepare our orders) so you can experience our preparation and distribution processes firsthand. Additionally, you will receive many introductory talks about our infrastructure, services/microservices, and the teams that maintain and develop them.
You will also have some time to create some simple functionalities from scratch to understand our development pipeline.
In 3 months
You will already be settled and working. You will know how we work, you will have met all of us, and you will know us all by name. You will actively participate in everything that happens. Dailies, plannings, groomings, kick-offs, demos, and retros are part of our team's rituals, but everyone chooses when and how to do them.
In 6 months
You will understand the SRE team's vision, why we do things the way we do, and what our objectives are. At this point, you will have much to contribute, you will understand what the priorities are, and you will be able to make informed decisions. Additionally, as a valuable member of the team, you will have participated in defining your team's common objectives. The rest of the team will have had time, will know you better, and may even dedicate some memes to you.
But... how can you get there?
From day one, you will work hand-in-hand with your buddy, who will support you in setting up your computer, accessing the necessary tools, and integrating into the team. After completing our onboarding process and being ready to work autonomously, you will continue to receive constant support and guidance from the entire team.

In their own words
About the company & team
At Mercadona Tech, we like to say that we are engineers with a product mindset. We do not see technology as an end in itself, but as a tool to achieve our goal: Selling Lettuce. This philosophy allows us to get involved in all phases of the process, collaborating closely with other roles, such as Product Makers and Process Owners, not just implementing solutions, but actively participating in the creation of valuable products.
We consider ourselves data-driven, as we have access to key data that allows us to make informed decisions. This provides us with a clear view of the impact of each action, both at an individual and team level, and helps us to continuously improve.
In our day-to-day, we work with feedback loops constantly. We are always looking for ways to maximize their effectiveness, while minimizing their size and cost. We adopt Lean development and Extreme Programming principles and practices, such as Pair Programming, TDD, or Small Safe Steps, among others, to keep solutions simple and avoid over-engineering.
In the SRE team, we work with a modern technical stack oriented toward facilitating the autonomy and efficiency of development teams, always maintaining high standards of reliability and observability. These are some of the technologies and practices that are part of our day-to-day:
A robust CI/CD structure based on GitHub Actions and containers, which allows us to automate deployments efficiently and securely.
We combine the Elastic (ELK) and Prometheus stacks to offer teams total visibility into the behavior of their applications and services, both at the log and metric levels.
Although our main function is to support development teams, we go further: we have our own roadmap for improvements and innovation.
Currently, we are exploring hybrid cloud solutions and developing automation tools for the creation of Kubernetes clusters, aligned with our scalability and self-service strategy.
