About the role

We're looking for an Applied AI Solutions Lead - a technically strong LLM engineer ready to step into leadership. You'll design and deliver data strategies for LLM training and evaluation, lead a small team, and work directly with customers to turn research goals into practical, high-quality AI data solutions.

What You'll Work On

• Bridge customers and engineering - understand client research goals, translate them into data strategies, and advise on best practices in LLM training and evaluation.
• Design and validate LLM data pipelines: prompts, datasets, audit methods, quality criteria, and evaluation workflows using Toloka's ML audit tools.
• Ensure data quality and success in training: anticipate which data or labeling strategies will lead to better model outcomes; define metrics and validation plans to prove it. 
• Collaborate cross-functionally with Product, ML, Business Development and Delivery teams to launch projects that meet timelines, scope, and client satisfaction.
• Act as a trusted advisor to customers - scope projects, identify pain points, and guide researchers on data-centric AI strategy.
• Drive fast iteration and continuous improvement, applying agile practices and evidence-based decision-making.

About You

• Hands-on ML & LLM Experience: You've trained or fine-tuned large language models and understand how data strategy, prompt design, latency, throughput and evaluation affect model quality and behavior. You think critically about data quality - what makes good training data, how to measure it, and how to improve it. You bring 5+ years of experience as an AI/ML Engineer or Software Engineer in an AI environment, ideally with a Master's or PhD in Artificial Intelligence, Computer Science, or a related field.
• Customer & Communication Excellence: You can talk to researchers and business stakeholders with equal confidence - translating technical concepts into clear, actionable solutions. You're great at scoping projects, identifying customer pain points, asking the right questions, and presenting ideas in polished, professional English.
• Strong Technical Foundation: You're fluent in Python and familiar with ML libraries such as Hugging Face, PyTorch, or OpenAI's APIs. You can prototype and evaluate LLM-based solutions independently. You bring all-around technical depth and innovate. You don't criticize existing solutions, you make them better.
• Project & Delivery Mindset: You've worked in project-based environments with external stakeholders, understand iterative software development, and can balance quality with speed in real-world delivery settings.
• Mindset: Curious, pragmatic, collaborative - you enjoy solving complex problems with customers, not just building models in isolation.

What we can offer

• You'll have the opportunity to work on highly innovative, projects at the leading edge of AI development, and work with a genuinely dedicated and dynamic team of experts.
• You'll also be working on projects with customers that are AI industry leaders and household names.
• Personal and career development: we support employee's ambition for professional development and encourage them to implement their ideas in their projects.
• Flexibility: we offer remote or hybrid employment. You will also design with your manager a workday that works best for you.
• Paid parental leave and sick leave.
