AI Engineer

Make Your Story Real

At Siili, we don’t just talk about AI – we make it real. We build AI-powered solutions that deliver measurable impact, combining data, design, and engineering. From recommendation engines to generative AI, our work goes beyond experiments and proof-of-concepts. We deliver solutions that scale and create value for our clients.

As an AI Engineer, you will play a key role in designing, building, and deploying machine learning and AI solutions that help organizations transform how they use data. You’ll work as part of our Data & AI community, alongside data scientists, data engineers, and data architects – but your focus will be on true AI engineering: making models work in production, ensuring reliability, scalability, and performance. 

What You’Ll Do

• Design and implement end-to-end AI solutions, from prototyping to production deployment.
• Build and optimize LLM-powered applications and agentic systems integrated into real business processes and systems.
• Collaborate with data scientists to turn models into robust, scalable products.
• Apply MLOps practices to ensure reproducibility, monitoring, and continuous improvement.
• Work with modern cloud environments (Azure, AWS, GCP) and open-source AI frameworks.
• Stay curious about the fast-evolving AI landscape, and bring that insight into client projects.

What we’re looking for

• We are looking for an experienced AI Engineer who has built real AI solutions – beyond using APIs or experimenting with models.
• We hope you recognize yourself in most of these:
• 2+ years of experience in AI/ML engineering or data science, with a solid understanding of key ML concepts such as classification, regression, NLP, and generative AI.
• Experience in building production-grade LLM and agentic applications, incl. evaluation, monitoring, and scaling.
• Knowledge of core LLM concepts e.g. tokenization, RAG, CoT, reasoning models, memory, fine-tuning, tool use, and self-correction.
• Hands-on experience with MLOps, CI/CD, containers, and cloud environments.
• Ability to design and maintain data pipelines, ensuring model reliability and performance in production.
• Curiosity and drive to stay ahead of developments in AI and apply them responsibly.
• Excellent communication and consulting skills — able to guide stakeholders, create understanding, and inspire confidence around AI capabilities.
• Fluent in Finnish and English.

Relevant Technologies:

• LLMs and LLM middleware: GPT, Claude, open-source models, LiteLLM, vLLM
• Agent technologies: MCP, agent/workflow frameworks (LangGraph, LlamaIndex, Haystack, Magentic, Strands)
• Platforms, e.g. Azure AI Foundry, Amazon Bedrock, Snowflake and Databricks
• Cloud: Azure, AWS, GCP
• Python
• Vector databases, e.g. Pinecone, pgvector
• AI powered development tools: ChatGPT, Cursor, GitHub Copilot, Claude Code, OpenAI Codex

What We Offer

• A technically strong and collaborative community: You’ll work alongside experienced data professionals who support each other, share insights, and aim for excellence in everything we do. Our culture values respect, autonomy, and peer-driven improvement.
• Opportunities to lead and influence: Whether you're passionate about architecture, data platforms, or AI enablement, you'll have the freedom to take ownership and shape solutions that matter.
• Real-world impact, not just buzzwords: You'll help deliver scalable, meaningful Data & AI solutions with clear ties to business strategy – not just experimental prototypes.
• Continuous learning, backed by top partnerships: We invest in your growth through mentoring, training, and hands-on access to the latest tools via our partnerships with Microsoft, Databricks, Nvidia and more.
• Practical benefits: Flexible hybrid work, well-being support, hobby clubs, daycare support for sick children, and a share option program.
• Company with a mission: We have a clear vision and purpose, and unique opportunity for you to make your mark as we shape the Data & AI story for a leading IT service company.
• Mental well-being at the core: We know that thriving at work requires more than technical skills. That’s why we offer support through services like Auntie and Focus Tiger, provide in-house coaching, and ensure that all our leaders have completed Brain-Friendly Leadership training with the NeuroLeadership Institute. You’ll have access to tools and support that help you take care of your mind as well as your career – because real impact starts with well-being.
• A culture shaped by Joy, Ambition, Responsibility and a Humane touch: At Siili, we believe that great results stem from meaningful work, psychological safety, and the courage to act responsibly. You’ll be trusted, supported and encouraged to grow as your authentic self – while contributing to a more sustainable digital future.
• At Siili, you’re not just coding models.
• You’re making AI real – in production, at scale, with impact.
