At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Technical Product Manager to play a key role in our calculations squad of the Platform Product team in Athens. If that’s you, and making a difference gets you out of bed in the morning, keep reading. It could be the start of something, well, extraordinary.

Sounds great, what will I be doing? 🤔

As our Technical Product Manager you’ll sit within the Calculations squad of the Platform Product team, who are responsible for GWI’s high-performance computation engine that processes billions of data points to deliver fast, accurate, and scalable insights. This system sits at the core of our platform, powering in-memory data processing across all our products and services. You’ll work closely with engineering teams to define how our core calculations, APIs, and data pipelines power end-user insights. You’ll ensure that our platform remains scalable, reliable, and future-proof, while translating highly technical capabilities into clear product outcomes.

This role is perfect for someone who loves solving complex technical challenges, thrives in cross-functional collaboration, and is excited by the idea of building systems that empower customers to uncover meaningful insights at scale.

You will:

• Define and own the roadmap and backlog for backend systems (calculation engine, APIs, data processing pipelines) that power insights across our platform.
• Translate technical detail into clarity; document expected system behaviors and calculations logic, write product requirements, and communicate technical changes to internal and external stakeholders.
• Collaborate with engineering leads to prioritize and deliver performance, scalability, and reliability improvements without disrupting team autonomy.
• Partner with cross-functional teams (Data Science, Research, Customer Success) to ensure backend capabilities align with product strategy and customer needs.
• Drive technical alignment by facilitating discussions, clarifying dependencies, and ensuring consistent delivery across multiple product squads.
• Evangelize the platform internally and externally, help stakeholders understand how our core systems translate into customer value.

It’s also fun; shaking things up is what working for a growing company is all about. So you’ll need to be flexible, comfortable with continuous change, and working in a high-tempo environment as we grow.

What do I need to bring with me? 🧳

You’ll need to be able to demonstrate the core skills this role requires. You don't have to tick all the boxes right away; the important thing is that you’re willing to learn. Here’s what the team will be looking for:

Equally important is attitude. We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, exemplified by our leadership team, and they’re a big part of what we’re looking for in you.
