• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model

• Network optimization (e.g., compressing front-end assets, minimizing payload size to the application server)
• Performance testing at scale (load, stress, soak testing; identifying bottlenecks under peak conditions)
• Fine-tune for scalability (horizontal scaling, load balancing, partitioning/sharding strategies)
• Asynchronous processing (job queues, batch processing, event-driven architectures)
• Database performance tuning (connection pooling, replication, failover strategies)
• Observability (metrics, logging, tracing, APM tools) to proactively detect and resolve issues
• Following strict governance on PII data.

Experience with agentic tools is a plus, but not required.

Job Responsibilities

We are looking for someone who not only identifies areas for improvement but actually resolves the issues.

We are looking for seasoned, self-starters who can identify bottlenecks, propose solutions, and execute independently.

Department/Project Description

Our client is an award-winning workforce and human capital management SaaS company, supporting hundreds of thousands of healthcare workers across the US. Senior care facilities are facing unprecedented workforce challenges. Our client provides a time-tested, industry-specific platform that allows providers to harness the power of real-time data, proactively manage their workforce, and improve measures of care quality and reimbursement, reduce costs associated with overstaffing and excess overtime, and ensure regulatory compliance.

We are seeking an experienced Mid/Mid+ Data Scientist with expertise in Large Language Models (LLMs) such as GPT, Claude, and related technologies. The ideal candidate will have a strong background in natural language processing (NLP), machine learning, and deep learning models. They will play a critical role in developing and deploying cutting-edge LLM applications to drive innovation across our product lines.
 

Responsibilities:

• Design, develop and optimize Large Language Models for various NLP tasks such as text generation, summarization, translation, and question-answering
• Conduct research and experiments to push the boundaries of LLM capabilities and performance
• Collaborate with cross-functional teams (engineering, product, research) to integrate LLMs into product offerings
• Develop tools, pipelines and infrastructure to streamline LLM training, deployment and monitoring
• Analyze and interpret model outputs, investigate errors/anomalies, and implement strategies to improve accuracy
• Stay current with the latest advancements in LLMs, NLP and machine learning research
• Communicate complex technical concepts to both technical and non-technical stakeholders.
   

Requirements:

• MS or PhD degree in Computer Science, Data Science, AI, or a related quantitative field
• 2-3+ years of hands-on experience developing and working with deep learning models, especially in NLP/LLMs
• Expert knowledge of Python, PyTorch, TensorFlow, and common deep learning libraries
• Strong understanding of language models, attention mechanisms, transformers, sequence-to-sequence modeling
• Experience training and fine-tuning large language models
• Experience with classical ML models - XGBoost, LightGBM
• Proficiency in model deployment, optimization, scaling and serving
• Excellent problem-solving, analytical and quantitative abilities
• Strong communication skills to present technical information clearly
• Ability to work collaboratively in a team environment
• Fluency in Ukrainian and English
   

Preferred:

• Research experience in LLMs, NLP, machine learning
• Experience working with multi-modal data (text, image, audio)
• Knowledge of cloud platforms like AWS, GCP for model training
• Understanding of MLOps and production ML workflows
• Background in information retrieval, knowledge graphs, reasoning
