  • At least seven (7+) years of professional software development experience using any modern backend stack (Python, Java, .NET/C#, Go, etc.), with demonstrated AWS cloud experience

  • Experience implementing and scaling ML models in production (MLOps), utilizing containerization technologies (Docker, Kubernetes) and serverless architectures.

  • Proven proficiency in Python and standard ML/scientific computing frameworks (e.g., PyTorch, TensorFlow, Scikit-learn).

  • Experience utilizing AWS ML services such as AWS SageMaker, AWS Bedrock, or comparable MLOps and Generative AI platforms from other cloud providers for model deployment and serving.

  • Experience leading a team of software developers.

  • Strong technical communication skills, ability to share concepts to various audiences.

  • Ideally, holding certification as an AWS Cloud Practitioner, AWS Certified Developer or AWS Certified Machine Learning Specialist or be willing to earn certification within the first year (supported and funded by Skywise ).

  • You have a College Diploma or Bachelor's Degree within the software engineering area of study or equivalent professional experience.
