Senior Backend Engineer

Shalion is an eCommerce intelligence company. Our platform brings digital shelf, retail media and food service data together and shows global brands exactly how their products perform online: availability, pricing, content and share of search. With Maestro, our conversational AI, they get answers in seconds and make better decisions, faster. Every day, we collect 100 million data points from over 2,000 retailers in 85+ countries, for brands such as Heineken, Lego, Danone, Nestlé, Coca-Cola and JDE.

We are about 140 people, with offices in Barcelona, Buenos Aires and New York, and colleagues across Europe, the Americas and Asia. The role We run several distinct products, each supported by its own team. We want to boost the product team and are looking for a Senior Backend Engineer who leads the backend initiatives, decides on the technologies we use, and leads new technical solutions for what we want to build next. This sits alongside our internal software team.

Beyond feature work, you will own a platform to automate workflows for our clients with a solution developed in-house and using AI. This is a product oriented role: you think in terms of what clients need, not only what gets shipped. You will be in regular contact with the product stakeholders and CEO, translating what they need into your technical roadmap. You will manage one engineer already in place from day one, with the team potentially growing further down the line.

The products are already live and in clients' hands; what you will build is the unified engineering function behind them, the frameworks, standards, and way of working. What matters is that you stay hands on, in the architecture and the tougher technology decisions, like tradeoffs on tech stack or when to rebuild versus patch, not just in oversight. This role works best for someone who wants to do both, manage people and stay technical, rather than choosing one over the other.

• Lead back end development across our products, owning the engineering roadmap for new features.
• Decide on and evolve the technology stack for these products.
• Manage the existing backend engineer, staying hands on in the work, with the team potentially growing further down the line.

• Bring AI and automation into the products themselves, finding where workflows can be automated to speed up delivery.
• Set up engineering frameworks, standards, and processes across the product portfolio, since none exist in a unified way today.
• Stay close to the product stakeholders directly, understand what they need, and translate that into a technical roadmap and new features, not just a delivery plan.
• Stay hands on. This is a building role.

5+ years of hands-on experience in back end engineering, ideally across multiple products, including at least 1 year in a management capacity
