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 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.
Make AI Real!
