What you’ll do

As a PhD intern, you will:

• Collaborate with research scientists to advance methods in:

  • Planning and RL for computer use (e.g. behavioral cloning, RL on model weights, RAG-based domain knowledge)

  • Multimodal grounding (e.g. vision-only models, tree search, hybrid methods with large models)

  • Reward/judge modeling (e.g. error analysis, human evaluation, training judge models)

  • User intent understanding (e.g. modeling vague queries, preference learning)

• Contribute to building datasets, running experiments, and benchmarking results

• Explore novel approaches and help derisk Simular’s long-term technical roadmap

• Document and communicate findings through internal reports or academic-style writing

You might be a fit if

• Currently pursuing a PhD in Computer Science, Machine Learning, or related field

• Research background in at least one of: Reinforcement learning, Large language/vision-language models, Computer vision and multimodal perception, Representation learning

• Experience conducting experiments and publishing or preparing papers in top-tier conferences (NeurIPS, ICLR, ICML, CVPR, ACL, etc.)

• Strong coding and prototyping skills in Python and ML frameworks (PyTorch/JAX)

• Curiosity, initiative, and interest in bridging fundamental research with applied AI
