Position Description We are seeking an experienced Senior LLM Engineer to join our team. You will play a key role in designing and implementing workflows that leverage large language models (LLMs, LAMs, LMMs, LVLMs, etc.) to automate the process and drive innovation in our products. The ideal candidate will have a deep understanding of NLP, experience with foundational models, and a flexible, problem-solving mindset. You will collaborate closely with cross-functional teams, contributing to the development of scalable AI-driven solutions. Major Areas of Responsibility Design, Implement, and optimize workflows that incorporate large language models to automate and enhance product features. Leverage existing foundational models and adapt them to fit into various product requirements, ensuring alignment with business goals.

• Own the Technical Blueprint: Personally architect the infrastructure solutions for our most strategic M&E partnerships, studio-scale content production pipelines, agency data consolidation plays, generative AI model deployments. • The Physics to P&L Narrative: Fluently demonstrate to executive stakeholders how infrastructure decisions, data lake locality, storage tiering, inference optimization, directly impact their business model and operability. • Deconstruct the Bottleneck: Go beyond the stated problem to find the technical truth. Translate vague business goals (e.g., “We need lower rendering costs”) into precise engineering requirements (e.g., “We need to optimize the inference batch size on L40s to reduce cost-per-token by 30%”). • Map the Transition: Identify exactly where a customer sits on the curve from legacy service bureau to AI-native tech platform and prescribe the specific infrastructure intervention needed to move them forward. • Build and Validate the Integration Layer: Identify, engage, and technically validate relationships with the most critical ISVs in the media and entertainment landscape, from rendering and VFX toolchains to generative AI platforms. • Define the Standard: It is not enough to support these tools. You will define the reference architectures for how they run best on Nebius infrastructure, and work directly with ISV engineering teams to build and publish those standards. • Decide What’s Worth Doing: In partnership with the GM, evaluate ISV and partner opportunities on their technical merit and strategic leverage, and be equally rigorous about what not to pursue. • Shape the M&E Roadmap: Use forensic evidence from the field to prioritize and justify the M&E vertical roadmap. You will work directly with Nebius’s global Head of Product and Head of Engineering to translate partner and customer needs into product direction. • Lead the M&E Product Summit: Chair a quarterly summit with Core Engineering leadership, using field evidence to drive roadmap decisions and maintain vertical momentum.

• Develop performant, scalable, and high quality APIs and backend processes for Ostro's SaaS platform, with a strong emphasis on LLM integration. • Collaborate with cross-functional teams to implement new features and refine existing ones, particularly those involving AI/LLM capabilities. • Provide feedback on roadmap and features for your team, contributing to the strategic direction of Ostro’s AI/LLM initiatives. • Ensure code quality and compliance through thorough reviews, unit testing, and adherence to best practices for LLM-powered applications and Ostro engineering. • Optimize application performance and scalability to meet user demands, especially for LLM inference and data processing. • Stay informed about emerging AI/LLM technologies, prompt engineering techniques, and industry trends. • Troubleshoot and resolve production issues, ensuring performance, reliability, and scalability of LLM-driven features.
