From free multicurrency accounts to powerful e-commerce tools, we’re here to support business owners of all sizes and everyone out there who dreams of starting their own business.

As we are expanding our team, we’re looking for AI engineer to help us make a real difference in the Fintech industry. Ready to join us and shape the future of payments? Let’s make it happen!

About the role:

As an AI Engineer, you'll design, build, and operate production-grade AI/ML systems - from agentic applications and MCP-powered tools to the underlying MLOps infrastructure and data foundations that make them reliable at scale. You'll sit at the intersection of applied AI, DevOps/MLOps, and data engineering, taking systems from prototype to production and keeping them healthy once they're there. Your work will power intelligent products and internal automation across the company, and will help shape how the organisation safely adopts AI at scale.

What you’ll do:

• Design and build agentic systems: single agents, multi-agent orchestration, and sub-agent patterns for complex workflows (planner/executor, supervisor/worker, hierarchical task decomposition)

• Develop MCP (Model Context Protocol) servers and tools that expose internal systems, datasets, and actions to LLM-powered applications in a safe, governed, and reusable way

• Implement retrieval systems (RAG, hybrid search, graph-based retrieval) including chunking, embedding, re-ranking, and context-assembly strategies

• Build and maintain MLOps automation: CI/CD for models and agents, environment management, artifact handling, and versioning of prompts, models, data, and code

• Implement observability for AI systems: tracing, token/latency/cost metrics, quality and drift monitoring, alerting, and incident response

• Build and maintain data pipelines for ingestion, transformation, and export across multiple sources and destinations

• Expose well-modelled, governed datasets and APIs that agents, tools, and downstream consumers can rely on

• Ensure secure data handling and compliance with relevant data protection standards and internal policies

  Contribute to documentation, standards, and continuous improvement of the data platform and engineering processes

This role is perfect for you if you have:

• Bachelor’s degree in Computer Science, Engineering, Mathematics, or a related technical field (or equivalent practical experience)

Nice to have:

• Strong GCP experience and ecosystem knowledge: Vertex AI (Agent Engine, Model Garden, Pipelines, Endpoints), Cloud Run, BigQuery, Composer, Dataproc, Cloud Run, Dataplex, Cloud Storage

Why you should join myPOS:

• Vibrant international team operating in hi-tech environment

• Annual salary reviews, promotions and performance bonuses

• myPOS Academy for upskilling and training

• Unlimited access to courses on LinkedIn Learning

• Annual individual training and development budget

• Refer a friend bonus as we know that working with friends is fun

• Teambuilding, social activities and networks on a multi-national level

What we offer:

• Excellent compensation package

• 25 days annual paid leave (+1 day per year up to 30)

• Full “Luxury” package health insurance including dental care and optical glasses

• Meal vouchers of 102.26 EUR per month
