Lila Sciences - Senior / Staff Machine Learning Engineer, Applied AI
Requirements
• Minimum 1-2 years of hands-on post-training experience (SFT, RL methods such as DPO/PPO/GRPO) and evaluation system design, gained from having solved these problems many times before. • Strong software engineering skills in Python and modern ML frameworks like PyTorch. • A demonstrated ability to debug ambiguous, high-stakes model behavior quickly, using data, traces, logs, and qualitative feedback - the kind of judgment that only comes from having seen many failure modes before. • Deep familiarity with large language models, multi-modal models, or agentic AI systems. • Clear communication skills for translating customer needs into technical approaches, and for explaining complex model behavior to both technical and non-technical audiences. • Experience adapting models for customer-facing or production workflows, ideally in scientific, technical, or data-intensive domains. • Experience with RL post-training, such as RLHF, GRPO, or tool-augmented RL. • Experience building evaluation harnesses, model monitoring, or quality dashboards. • Experience training MoE architectures. • A track record of mentoring engineers and being sought out as a go-to technical expert, rather than a people manager or strategy owner.
