SENIOR MACHINE LEARNING ENGINEER (SMLE) - Sweden

As a member of Modulai you will be working with a broad range of problems with one common denominator โ€“ ML will be the key ingredient. As a SMLE you will be responsible for team success and advisory to both teams and clients.

In this role, you will be responsible for engaging clients and teams from the initial idea phase through to execution. We are looking for someone with a proven track record of successfully developing end-to-end ML products and leading teams in both commercial and delivery settings. It's important that you have a passion for ML and strong opinions on how to succeed in applied ML. At our company, being a lead is not just a formal title; it's a responsibility to help others achieve even greater success.

You will have to analyze the problem at hand, devise a solution strategy, and execute it. This typically entails gaining an in-depth understanding of the challenge, understanding the available data, and then re-formulating it as an ML problem. It requires openness, creativity, and an eagerness to learn new methodologies and explore new terrains.

We approach these problems as a team where great leaders are essential, meaning that you will have to be able to clearly explain your reasoning and code to engage the team as well as clients, investors, and others.

About Team Modulai

At Modulai, we focus 100% on solving problems with machine learning (ML). We work in teams on a project basis, for clients, as part of the core team in startups where we have long-term engagements, and we also build our own ML products.

Learning and teamwork are central to how we work. Everyone in the team is or will soon be a full-stack ML engineer capable of scoping and developing end-to-end ML solutions. You should be able to do end-to-end machine learning products by yourself but never do it because we always work in teams. If there is data, we will do ML on it!

About the Company

Name: modulai.teamtailor.com
Location: Stockholm

We are machine learning engineers, AI researchers, software developers and data scientists. But first and foremost, we are innovators. We just like to try, everything. When we say that no ideas are too crazy for us, we mean it. But we have our feet on the ground (or hands on the keyboard, if you will). We explore new avenues, assess the achievability of a goal, research, and try it out. We work iteratively, piece by piece, to produce a concept, from idea to final product.

This mindset, of exploration and curiosity, is the foundation of how we work. We all stem from STEM, which means we have something in common: the urge to not take anything for what it seems to be. We encourage expanding our perspectives through machine learning breakfasts, journal clubs, book circles, hackathons, and spontaneous whiteboard sessions. Making โ€œlearningโ€ the primary activity inside and outside of projects results in an equal team where your eagerness to learn, collaborate and develop speaks higher than any KPI.

The right place to develop your ML & AI skills With challenging projects, daily stand-ups, whiteboard sessions, and ongoing discussions surrounding AI, we aim to support you with everything to expand your knowledge. We like to say that the more you know individually, the more we know collectivelyโ€” a saying that rests on one strong foundation of our micro-culture; to share learnings.

Innovation thrives in teamwork We always make sure to be at least two on every project because we are firm believers in collaboration. By constantly working in teams, we help each other develop new areas, learn from each other, and share perspectives. We are building an open and inclusive workplace where we rather say, letโ€™s try it than no. Innovation flourishes in diversity; diversity of background, thought, and culture.
