Your role

We are looking for a Senior / Lead AI Scientist to develop Krosswise AI's agentic capabilities and lead the technical delivery of AI solutions for our clients. You will work in an experienced team where agentic development is not an experiment but the way we work.

In this role, you will develop agentic capabilities that enable us to efficiently produce tailored agentic solutions built on the latest AI, including sovereign environments. You will lead client deliveries of AI solutions in a technical role, making sure that what we build works as intended and meets our clients' requirements. We've been building our capability for a while now and our core team is running at full speed, yet we're still early enough that you will have a real say in what Krosswise AI looks like tomorrow.

What we expect

• At least 5 years, preferably 10 years, of relevant experience
• Strong experience in classical AI and machine learning
• Experience in implementing agentic solutions and agentic development in a key role
• In-depth understanding of generative AI models and methods
• Experience in conceptualising AI solutions and defining requirements together with clients

Experience and expertise in the following will be considered an advantage:

• A master's degree
• Previous experience in a consulting role in software development or data engineering
• Experience, vision or interest in leading change

Due to the nature of our projects and our strong sense of community, we work in a flexible hybrid model, which means being prepared to work at our office in Tampere (GO21 building) or Helsinki (Aleksanterinkatu) when needed. If you’re based in the Turku region, we’d be glad to hear from you too.

Our working language is English. Please note that we do not offer relocation support. Employment is conditional on passing an official security clearance and/or a drug test.

With us, you will have the opportunity to help build a new success story

We are in a very exciting phase of growth, and you can truly make an impact. In addition, we offer:

• A competitive salary, which for this role is €6,000–8,000 per month depending on your skills and experience
• Comprehensive and diverse employee benefits, including extensive occupational healthcare and accident insurance, sports and culture benefits, lunch benefits, a company mobile subscription and home broadband, as well as modern work equipment of your choice
• Support for your professional development in mutually agreed ways, from mentoring to training, and from certifications to coaching – for example, we have supported doctoral studies alongside work
