Job Description

OpenAI's Training team is responsible for producing the large language models that power our research, our products, and ultimately bring us closer to AGI. Achieving this goal requires combining deep research into improving our current architecture, datasets and optimization techniques, alongside long-term bets aimed at improving the efficiency and capability of future generations of models. We are responsible for integrating these techniques and producing model artifacts used by the rest of the company, and ensuring that these models are world-class in every respect. Recent examples of artifacts with major contributions from our team include GPT4-Turbo, GPT-4o and o1-mini. As a member of the architecture team, you will push the frontier of architecture development for OpenAI's flagship models, enhancing intelligence, efficiency, and adding new capabilities.

Job Responsibility

  • Design, prototype and scale up new architectures to improve model intelligence
  • Execute and analyze experiments autonomously and collaboratively
  • Study, debug, and optimize both model performance and computational performance
  • Contribute to training and inference infrastructure

Requirements

  • Experience landing contributions to major LLM training runs
  • Can thoroughly evaluate and improve deep learning architectures in a self-directed fashion
  • Motivated by safely deploying LLMs in the real world
  • Well-versed in the state of the art transformer modifications for efficiency
  • Deep understanding of LLM architectures
  • Sophisticated understanding of model inference
  • Hands-on empirical approach

What we offer

  • Medical, dental, and vision insurance for you and your family, with employer contributions to Health Savings Accounts
  • Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses (parking and transit)
  • 401(k) retirement plan with employer match
  • Paid parental leave (up to 24 weeks for birth parents and 20 weeks for non-birthing parents), plus paid medical and caregiver leave (up to 8 weeks)
  • Paid time off: flexible PTO for exempt employees and up to 15 days annually for non-exempt employees
  • 13+ paid company holidays, and multiple paid coordinated company office closures throughout the year for focus and recharge, plus paid sick or safe time (1 hour per 30 hours worked, or more, as required by applicable state or local law)
  • Mental health and wellness support
  • Employer-paid basic life and disability coverage
  • Annual learning and development stipend to fuel your professional growth
  • Daily meals in our offices, and meal delivery credits as eligible
  • Relocation support for eligible employees
  • Additional taxable fringe benefits, such as charitable donation matching and wellness stipends, may also be provided

Requirements
Requirements
  • 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?'
Job Responsibility
Job Responsibility
  • Own the full lifecycle of Lovable's post-training pipeline - from data curation and training runs through evaluation and deployment
  • Apply and adapt reinforcement learning, preference optimization, and supervised fine-tuning methods to make our models better at generating code, reasoning about user intent, and acting as reliable agents
  • 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
