AI Platform Engineer

6 hours ago

Helsinki, Uusimaa, Finland Polar Squad Full time

We are looking for AI Platform Engineers to help our clients build strong foundations for AI use in real business environments. You will work with cloud, data, and machine learning systems that support the reliable adoption of AI at scale.

Who We Are
Polar Squad helps companies make the tech work meaningful. We build platform solutions for engineers, help our clients get AI-ready, and create environments where technology supports real business value.

We aim for a warm, personal, and modern approach to cloud, platform engineering, data, and AI.

What You'll Do
In this role, you are part of client teams designing and building modern AI and data platforms. Your work makes it possible to train, deploy, and operate AI systems in a trusted and efficient way.

You will:

  • Build and maintain platform components that support AI workloads such as model training, inference, vector search, data preparation, and feature processing
  • Design pipelines and workflows for data and model delivery, covering both batch and real-time cases
  • Work with various data types and design models that serve analytics and machine learning needs
  • Implement storage solutions like warehouses, lakes, and lakehouses with the right balance of security, cost, and performance
  • Ensure reliability in data and model flows through testing, monitoring, and clear governance
  • Work closely with data scientists, ML engineers, and platform teams to make sure models can run safely and at scale
  • Support deployment, versioning, and monitoring of AI and ML models, including evaluation and rollout strategies
  • Take part in shaping Polar Squad's approach to AI platforms, tools, and ways of working

What We're Looking For
Must-haves

  • Strong hands-on experience with Python or similar languages for platform and pipeline work
  • Solid skills in SQL
  • Experience with modern data or AI platforms such as Databricks, BigQuery, Snowflake, Redshift, or lakehouse setups
  • Cloud experience in AWS, GCP, or Azure
  • Experience with workflow tools such as Airflow, dbt, Prefect or Dagster
  • Understanding of data modeling and schema design for analytics and ML
  • Familiarity with deploying or supporting AI and ML workflows in production
  • Nice-to-haves
  • Experience with real-time systems (Kafka, Kinesis, Pub Sub)
  • Experience with feature stores, vector databases, or model registries
  • Knowledge of observability, lineage, and quality tools
  • Awareness of privacy, security, and compliance practices (for example, GDPR)

Why this role matters
Many organizations want to move forward with AI, but they lack stable foundations such as data quality, scalable runtimes, and safe deployment pipelines. As an AI Platform Engineer, you help them create these foundations so they can use AI in a trustworthy and practical way.

What We Offer

  • Work that matters, building AI and data platforms for companies in many industries
  • Real influence you help shape our tools, choices, and ways of working
  • Collaboration with skilled cloud engineers, platform engineers, and advisors
  • Learning and growth with new data and AI technologies
  • Flexible working setup and a healthy work-life balance
  • Competitive salary and benefits

If this sounds like the right next step for you, we'd love to hear from you
If this sounds like a good next step for you, we would love to hear from you. Please send your CV or a link to your LinkedIn profile and share a short story about a data or AI challenge you have solved.

Please note while applying:
we are currently only able to hire talents within the EU, preferably located in Finland or Spain (Malaga). Regarding the requirements listed above, we know that the perfect candidate does not exist - we are all a mix of different skills and experiences, and that is great. If you could see yourself working at Polar Squad and have over 8 years of technical experience - we would love to hear from you.

Note for and regarding agencies/recruitment companies:
we are happy to take good care of our recruitment process and valuable candidates on our own, no external assistance required at this point.
