Senior AI Backend Engineer - Siemens Mobility

Hiire is supporting Siemens Mobility in the search for a Senior AI Software Engineer to join a team focused on building enterprise-grade AI solutions with direct impact on critical business operations and workflows.

This is an opportunity to work in a highly technical and multidisciplinary environment where AI, software engineering, and product thinking come together to create scalable solutions for real-world problems. We are looking for someone with a hands-on mindset, strong production focus, and experience turning AI prototypes into robust and reliable systems.

What You’ll Do

• Collaborate closely with engineering, operations, and business stakeholders to understand workflows, identify pain points, and design AI-driven solutions with measurable impact.

• Translate complex requirements into scalable AI-enabled services and technical concepts.

• Contribute directly to the design and architecture of systems powered by LLMs and retrieval technologies.

Build AI Systems for Production

• Develop and maintain scalable, production-grade AI services focused on:

  • LLMs

  • RAG pipelines

  • Hybrid retrieval

  • Semantic search

  • Vector search

  • Agentic workflows

• Build backend APIs, data pipelines, and integrations while ensuring reliability, observability, and engineering best practices.

• Own the full development lifecycle: architecture, implementation, testing, deployment, and monitoring.

AI Evaluation, Prompt Engineering & Data Quality

• Design rigorous evaluation strategies for AI output quality, retrieval accuracy, and model behavior.

• Treat prompt engineering as an engineering and experimentation discipline.

• Ensure high standards for data quality and contextual grounding across AI systems.

• Mentor junior team members on AI engineering, experimentation, and evaluation practices.

What We’re Looking For

• 5+ years of experience in Software Engineering, with strong exposure to AI, NLP, or Information Retrieval.

• Proven experience building and operating AI solutions in production and enterprise environments.

• Ability to bridge experimental Data Science workflows with reliable and maintainable software engineering practices.

Technical Skills

• Strong proficiency in modern Python (3.11+), including:

  • async/await

  • typing

  • Pydantic

• Experience with:

  • Docker

  • CI/CD

  • testing frameworks (pytest)

  • code quality tooling (ruff, mypy)

  • Git workflows and code reviews

• Hands-on experience with:

  • LLMs

  • Prompt Engineering

  • RAG

  • GraphRAG

  • Vector databases / OpenSearch

  • AI evaluation pipelines

Nice to Have

• Experience with AWS Bedrock or Azure OpenAI.

• Familiarity with MCP (Model Context Protocol) and modern AI interface standards.

If you’re looking for an opportunity to work on applied AI in a serious, scalable, and impactful environment, this could be a very exciting next step.
