Accountabilities

• Design, train, and optimize computer vision and multimodal machine learning models that convert complex inputs into accurate, structured data.

• Fine-tune and evaluate multimodal models using techniques such as Low-Rank Adaptation (LoRA) and hyperparameter optimization to improve accuracy, speed, and cost efficiency.

• Build and maintain scalable data pipelines to prepare, validate, and organize production data for model training, testing, and evaluation.

• Develop robust evaluation frameworks and performance metrics to compare models, measure accuracy, and guide deployment decisions.

• Deploy and manage machine learning models on scalable cloud infrastructure, using automated scaling, monitoring, and controlled rollouts to maintain reliable performance.

• Integrate machine learning models into real-time processing systems and enhance computer vision capabilities, including image preprocessing, barcode decoding, and optical character recognition (OCR).

• Collaborate with Engineering, Fulfillment Operations, and other cross-functional teams to identify opportunities, improve workflows, and strengthen systems supporting lottery fulfillment.

• Promote engineering excellence through code reviews, technical documentation, automated testing, and mentorship.

• Contribute to the development and improvement of the team's broader data infrastructure.

Requirements:

• Bachelor's degree in Computer Science, Engineering, Mathematics, Data Science, or a related discipline, or equivalent practical experience.

• At least 3 years of experience in machine learning engineering.

• Proven experience developing, deploying, and maintaining machine learning models in production environments.

• Strong proficiency in Python and software engineering best practices, including automated testing, data validation, and asynchronous programming.

• Hands-on experience with computer vision, multimodal models, or vision-language models.

• Familiarity with machine learning frameworks and libraries such as PyTorch, Hugging Face Transformers, PEFT, or vLLM.

• Experience with model fine-tuning, prompt design, performance evaluation, and image processing tools such as OpenCV.

• Experience with cloud-based machine learning platforms, preferably Google Cloud.

• Familiarity with containerization, orchestration, and monitoring tools such as Docker, Kubernetes, GitHub Actions, or Datadog.

• Strong technical ownership, analytical thinking, and problem-solving skills, with the ability to lead complex initiatives and make sound technical decisions.

• Excellent communication and collaboration skills, including the ability to explain technical concepts and work effectively across teams.

• Familiarity with Kotlin, Java, message-driven architectures, or Protocol Buffers is an advantage.

• Experience in lottery, gaming, financial technology, or other regulated industries is considered a plus.

Benefits:

• Salary: US annual base salary range of $134,400–$168,000, depending on work location, relevant skills, experience, education, and training.

• Bonus opportunities and equity compensation, as applicable.

• Benefits package for eligible employees.

• Opportunity to work remotely within the United States.

• Full-time employment.

• Opportunity to develop and deploy advanced machine learning and computer vision solutions with real-world operational impact.

• Potential requirement to obtain a gaming license from the relevant state agency as a condition of employment.
