• You will have the opportunity to show who you are throughout our interview process; we don’t ask any trick questions or expect you to perform a whiteboard exercise. We want to see you shine by showing us work you are most proud of!
• Train and fine-tune supervised learning models (e.g., classification, ranking, embeddings) for internal tools and customer-facing product features
• Lead prompt engineering and testing efforts to fine-tune LLM behavior for specific use cases across the product suite
• Design and implement evaluation pipelines for both LLMs and traditional ML models
• Work with and optimize Elasticsearch-backed data systems that power AI and intelligence pipelines
• Proactively identify opportunities to improve AI models, data pipelines, and engineering workflows beyond the existing roadmap
• Develop tools and frameworks to support prompt iteration, model benchmarking, and performance tracking
• Coordinate with security team to ensure adherence to AI compliance standards
• Evaluate and compare commercial and open-source LLMs (e.g., OpenAI, Anthropic, Mistral, Meta, etc.) for performance, cost, alignment, and reliability
• Collaborate with product and engineering teams to integrate AI features in a safe, scalable, and maintainable way
• Monitor, evaluate, and continuously improve the performance of AI and machine learning models in production
• Stay informed of emerging research in NLP, machine learning, and AI infrastructure, and evaluate potential applications for the business
• Contribute to AlertMedia’s culture, values and vision for the future

• Team Building and Celebrations: Take part in company celebrations, team buildings, and peer-nominated value award recognition- You are an applied AI and machine learning engineer with strong data science fundamentals, deeply curious about what’s possible with large language models and practical machine learning applications
• You’re a collaborative engineer who thrives in a fast-moving environment, and you’re as comfortable training and fine-tuning models as you are crafting prompts or evaluating model outputs
• You have a strong understanding of ML fundamentals, but you’re pragmatic in applying the right solution for the problem
• Familiarity with model evaluation best practices, including offline metrics, cross-validation, and A/B testing
• The ability and desire to work in a fast-paced challenging environment
• 4–6+ years of experience in data science and/or software engineering, specifically in machine learning engineering, or applied AI
• Experience working with Elasticsearch or other large-scale search and indexing platforms
• 2+ years of software engineering experience, Python preferred
• Strong organizational skills and ability to manage working on multiple projects in parallel
• Proficiency in Python and ML libraries (e.g., scikit-learn, PyTorch, TensorFlow, Hugging Face)
• Experience with cloud-based ML tooling (e.g., SageMaker, Bedrock) and data workflows
• Experience with prompt engineering, model fine-tuning, and evaluation
• Demonstrated experience training and deploying supervised learning models, ideally in production environments (a plus)
• Strong understanding of LLMs and traditional machine learning methods
• Bachelor’s degree in a technical field such as computer science, computer engineering or related field preferred
• Ability to work independently and collaboratively on cross-functional teams
