Machine Learning Team Lead

📍****Location: Greece

🏙️ Office requirement: Remote/ Flexible-first

📝 Employment type: Permanent

⛰️ Seniority level: Mid-Senior

At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Machine Learning Team Lead to play a key role in our Data Science Department 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 Machine Learning Team Lead, you’ll be accountable for the results of a team of machine learning engineers, through which you will help us shape and realise our data science strategy. In particular, you will be involved in how GWI moves to consolidate its data. You will define the team’s operating standards and allocations based on your domain knowledge. You will help your team grow either literally through hiring or figuratively through structured learning and development goals.

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:

👉 Experience directly managing and growing a diverse and inclusive data science and/or machine learning engineering team

👉 Professional experience in statistical or machine learning, and bringing data products into production

👉 Being able to translate business requests into incremental Data Science solutions and evaluate their business value

👉 High level of coding proficiency in a technical language such as Python (pandas, numpy, sklearn, matplotlib or seaborn)

👉 Strong Mathematical skills in probabilities and statistics, linear algebra and optimization techniques

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.

Interview steps 👟

👉 Preliminary phone call with the Talent Team (no video required)

👉 First video interview with the hiring managers

👉 Second (and final) video interview* with the hiring panel, often including a presentation, followed by a values conversation with members of the wider GWI community.

• Don’t be alarmed if there are other stages in the process, it’s all part of the plan for some of our roles.
