We empower our people to stay resilient and relevant in a constantly changing world. We're looking for people who are always searching for creative ways to grow and learn. People who want to make a real impact, now and in the future. Does that sound like you? Then it seems like you'd make a great addition to our vibrant international team. DAI AIX – AI Acceleration and Exploration, is working on the cutting-edge research of Data Analytics and AI with Siemens global technology network, and consulting, co-creation, data driven applications for the end customers. Research Scientist is to do applied research for Industrial AI applications in the team. We are seeking a Reinforcement Learning (RL) Specialist to lead the design, implementation, and optimization of RL-driven systems for post-training of foundation models. The primary focus of this role is advancing our RL capabilities for real-world applications such as industrial control systems and LLM agents. You will develop cutting-edge algorithms, improve post-training efficiency, and deploy scalable RL solutions in industry.

You'll make an impact by

• 1. Reinforcement learning development for post-training:
  • Design and implement state-of-the-art RL algorithms (e.g., PPO, SAC, DQN) for post-training of foundation models like LLMs and time series foundation models.
  • Implement distributed RL training pipelines using frameworks like Ray RLlib, Deepspeed, or custom solutions.
  • Design and implement benchmark pipelines for model evaluation.
• 2. Align foundation models like LLMs and time series foundation models with specific areas/tasks through techniques like SFT, RL.
• 3. Coding & Infrastructure:
  • Write production-grade Python code using PyTorch, numpy, and pandas.
  • Manage Linux-based clusters for distributed training and deployment.
• 4. All other support required by the line manager if necessary.

Your defining qualities

• Master's or Doctor degree or above in Computer Science, Automation, Mathematics or related.
• Self-motivated, good communication skills and good team player.
• Ability to handle multiple competing priorities in a fast-paced environment.

The skills you are expected to have:

• 1~3 years of hands-on RL experience (academic or industry).
• Expertise in deep RL algorithms (model-based/model-free) and frameworks (e.g., RLlib, Gymnasium).
• Strong Python skills with PyTorch/TensorFlow and proficiency in Linux.
• Experience with distributed training (Horovod, DeepSpeed) and cloud platforms (AWS/Azure/Alicloud).
• Familiarity with LLM agents or LLM post-training.
• Prefer: Background in robotics, control systems, or game AI.
• Prefer: Contributions to RL open-source projects or publications at top conferences (NeurIPS, ICML, ICLR, KDD, IROS, etc).

You'll benefit from

• Diverse and inclusive culture, doing the work you like with people who appreciate it
• Systematic career development platform, various training courses, and online learning resources for you to help you tailor your growth path based on your strengths
• 15 days+ annual leaves, with additional benefits such as Christmas leave
• Generous benefits package, long-term care corporate annuity plan, flexible allocation of commercial insurance, employee stock sharing matching plan for mutual growth, etc
