Siemens Mobility is a leading provider of innovative mobility products and solutions, covering the full rail asset lifecycle through hardware, software, and services. Our mission is simple but ambitious: help customers make better decisions by turning IoT data from rail assets into reliable, actionable insights!

Are you passionate about building AI systems that actually run in production and create long‑term value? Do you enjoy combining strong software engineering with advanced AI techniques? If so, this role might be for you.

Your Impact

As a Senior AI Engineer, this role plays a key part in transforming real user needs across Siemens Mobility into scalable, production‑grade AI services. The focus is on engineering reliable systems that last—AI is not the end goal, but a powerful enabler.

From early understanding of user workflows to deployment and monitoring, the work directly impacts how teams across engineering, tendering, and operations solve complex problems every day.

What You’ll Work On

How do user problems turn into usable AI products? By working closely with internal stakeholders, understanding their workflows in depth, and identifying where AI can genuinely add value. These insights are translated into AI‑enabled service designs that go far beyond prototypes and make it into daily use.

Strong emphasis is placed on data‑centric development and robust evaluation. Prompt engineering is treated as a structured discipline, supported by measurable evaluation strategies and high‑quality datasets. In parallel, there is an active role in mentoring junior engineers and working students, guiding them through experiments, evaluation methods, and continuous improvement.

On the engineering side, the role involves building and operating production AI services using LLMs, RAG and hybrid retrieval approaches, and vector search technologies. Features are owned end‑to‑end—from design and implementation to deployment, monitoring, and ongoing improvement—within modern CI/CD and software quality standards.

Your Background

This position is best suited for someone with a strong software engineering foundation and significant experience working with AI systems in production environments. A degree in Computer Science, IT, or a related field is expected, along with 5+ years of hands‑on experience in AI, NLP, or Information Retrieval.
