Job Description:

The Post-Training team focuses on adapting foundation models to real-world performance and alignment requirements. Their work informs how Distyl leverages foundation models safely, effectively, and at scale across industries.

Job Responsibility:

  • Researchers develop and evaluate techniques such as supervised fine-tuning, preference optimization (DPO, RLHF, RLAIF), and continual adaptation to align models with Distyl’s enterprise systems
  • Researchers in Post-Training investigate new methods for aligning large models with human and system-level objectives. They explore trade-offs between generalization and specialization, data efficiency and robustness, capability and controllability

Requirements:

  • Deep Understanding of Post-training Techniques: Familiarity with supervised fine-tuning, preference optimization (RLHF/DPO), LoRA/PEFT, and instruction-tuning pipelines
  • Experience Adapting Frontier Models: You’ve tuned or adapted LLMs/SLMs to specialized domains or behaviors through data curation, reward modeling, or continual pretraining
  • Experience Building with Models, Not Just Building Models: We develop intelligent systems using models rather than training or fine-tuning them. Ideal candidates have expertise in compound AI systems, agentic collaboration, and associated techniques (ensembling, ReAct, graph-of-thoughts, etc.)
  • Proven Track Record of Research Results: Whether you’ve published in top journals, posted amazing work on twitter, or somewhere else we want to see what you've done
  • Uses AI Every Day: Before you can revolutionize someone else’s workflow, you need to revolutionize yours. You should be using tools like ChatGPT, Cursor, and Perplexity to accelerate your workflow
  • Strong Programming and Data Analysis Skills: While you might not consider yourself a software engineer you need to be able to build prototypes of your ideas and then perform the experiments to prove the effectiveness to a F500 Head of AI
  • Biases Towards Showing vs Telling: Our customers want to see the power of AI today vs discuss the most elegant idea that will take 5 years to realize
What we offer:
  • 100% covered medical, dental, and vision for employees and dependents
  • 401(k) with additional perks (e.g., commuter benefits, in‑office lunch)
  • Access to state‑of‑the‑art models, generous usage of modern AI tools, and real‑world business problems
  • Ownership of high‑impact projects across top enterprises
  • A mission‑driven, fast‑moving culture that prizes curiosity, pragmatism, and excellence
  • meaningful equity

  • You've personally run post-training jobs on large language models - RFT/RLVR, preference optimization, or similar. Not just called APIs or written prompts, but actually trained and iterated on models
  • You can write solid production code. The systems you build need to run reliably, not just produce interesting research artifacts
  • You're fluent in at least one major ML framework (PyTorch, JAX) and comfortable working with distributed training setups and GPU clusters
  • You understand the math behind preference optimization, reward modeling, and alignment techniques - and can reason about when each approach fits
  • You've built or significantly contributed to evaluation systems that capture real-world quality, not just benchmark scores
  • You can trace a model quality regression from user-facing symptoms back through serving, inference, and training - and you enjoy doing it
  • You want to ship. Research taste matters, but at Lovable the question is always 'how fast can we get this to users?'

  • Build the evaluation and experimentation infrastructure that tells us whether a model change actually helps users - covering helpfulness, safety, latency, and reliability
  • Develop and operate the production systems that run training jobs at scale, including GPU orchestration and data pipelines
  • Work across team boundaries with our agent, product, and infrastructure engineers to turn model gains into product improvements users can feel
  • Investigate and resolve failures end-to-end - whether the root cause is in a training recipe, a data issue, or a serving regression
  • Read papers, run experiments, and move fast: the goal is to get promising research into production within days or weeks, not months
