The role

Reporting to:

Manager, Platform Automation

Job role and purpose:

The AI Engineer will be responsible for designing, developing, and deploying AI solutions on cloud platforms. This role involves collaborating with cross-functional teams to integrate AI capabilities into existing systems, creating scalable, efficient, and secure AI infrastructure.

The role involves developing, programming, and training complex AI algorithms to function like a human brain. AI Engineers must be experts in software development, data science, data engineering and programming. They uncover and pull data from a variety of sources; create, develop and test machine learning models; and build and implement AI applications using embedded code or application program interface (API) calls. This role requires occasional travel based on business needs.

Main responsibilities & tasks:

AI engineers play a crucial role in developing and implementing AI based solutions. The responsibilities of this role have evolved to meet the demands of modern generative AI applications and fall under multiple categories. Here are the key facets of the job of AI Engineer, followed by responsibilities.

Key areas of responsibility include:

· Designing and implementing solutions on cloud platforms (Azure, AWS) using LLMs

· Collaborate with cross-functional teams to design and implement AI solutions

· Explore cutting-edge technologies for optimal design and implementation of solutions.

· Creating best practices for implementing AI solutions on cloud platforms

· Implementing data transformation and data ingestion infrastructure

· Building, maintaining and optimizing AI models

· Confirm that Security is high enough level on AI related systems

Other accountabilities & tasks:

· Extensive knowledge of statistics, calculus or algebra to work with algorithms and an understanding of probability to interact with some of AI's most common machine learning models, including Naive Bayes, hidden Markov and Gaussian mixture models.

· Proficiency with programming languages such as Python, Java or R to develop and deploy AI models.

· Solid understanding of algorithms and applied mathematics to build, modify and use AI models.

· Good knowledge of NLP, which combines computer science, information engineering, linguistics and AI in one system, plus the ability to program the system to process and analyze large data sets.

· Familiarity with generative AI frameworks and architectures, such as transformers and generative adversarial networks (GANs).

· Experience with LLMs and their applications.

· Knowledge of prompt engineering and fine-tuning techniques for generative AI models.

· Understanding of potential biases and ethical considerations in AI systems.

· Proficiency in working with cloud-based AI platforms and services (Azure and AWS).

· Experience deploying secure solutions to cloud using Terraform.

· Knowledge of GenAI and Machine Learning Cloud services (Azure ML, SageMaker).

· Communication and teamwork skills are highly valued as well as ability to work independently and sometimes even under some time pressure.

· Positive attitude and desire to help others are also valued.

· Strong communication skills English. Finnish language fluency considered as a plus.

Please note that the person selected for this role needs to pass the Finnish security clearance (perusmuotoinen turvallisuus-selvitys).
