About the role

We are looking for a Senior  Principal Engineer.

Someone who does not work from closed requirements, but rather understands the problem in depth, questions it when necessary, and proposes solutions and improvements.

This is a technical role, close to the teams and the product, where responsibility is not limited to defining, but also to building and supporting what goes into production.

What you'll do

A significant part of the role involves understanding the system and the context in which it operates. This means working close to real users —in stores, logistics, or operations— and understanding how systems affect specific business processes. Based on that understanding, you are expected to be able to identify underlying problems, not just symptoms, and to propose simpler or more effective alternatives.

On the design side, you will actively participate in defining technical solutions from early stages. You will translate complex problems into solutions that are maintainable and evolvable over time, making decisions about architecture, data models, APIs, or integrations. The use of data and AI capabilities will be a natural part of this process, both to improve the products themselves (automation, optimization, assistants) and to accelerate solution exploration and decision-making.

The role maintains a direct connection to implementation. It is not just about judgment, but also the ability to get into the details when necessary: reviewing code, participating in technical design decisions, or contributing directly to unblock specific situations. In this context, the use of AI tools applied to development (code assistance, testing, analysis) is part of the day-to-day to improve quality and speed.

Additionally, you will work with multiple teams, helping to raise the quality of technical decisions and maintain consistency across systems. This involves detecting unnecessary complexity, aligning approaches when there are dependencies, and proposing simpler ways to solve common problems. Part of the role also involves driving practical use of AI in engineering and product, ensuring its adoption makes sense from both a technical and business standpoint.

Technology

About the company & team

We are a global company where technology is key to making the business run every day: in stores, ecommerce, logistics, transportation, distribution, people, and finance.

We are changing how we design and build technology: small, autonomous teams with real responsibility.

Less intermediation. More judgment. More ability to make decisions close to the problem.

We believe the best products emerge when engineering understands the full context: the people, the processes, the data, and the technology that connects them.

You will work in an environment with small teams and real autonomy over product and technology. The systems are evolving, which means there is room to improve, simplify, and build better on top of what already exists.

The context is broad and the problems are complex, which allows you to have an impact beyond a single team or domain, while always staying close to the product and to what happens in production.
