Senior Software Engineer

• Design, develop, and deploy AI/ML microservices using Python in a cloud-native environment.
• Build scalable pipelines for training, tuning, and serving ML models in production.
• Integrate and manage NoSQL databases (e.g., MongoDB, ElasticSearch) for efficient storage and retrieval of unstructured or time-series data.
• Optimize model accuracy, latency, and throughput, including hyperparameter tuning, feature engineering, and profiling model performance.
• Lead the development of ML-based solutions for anomaly detection, time series forecasting, and predictive analytics.
• Collaborate with cross-functional teams to translate product requirements into ML-based features.
• Apply best practices in model versioning, A/B testing, and continuous training/validation.
• Ensure high standards of code quality, modularity, and observability in deployed services.
• Evaluate new tools, technologies, and frameworks for ML lifecycle management and monitoring.

• 5+ years of experience in backend software development using Python.
• Strong programming expertise in Python, with proficiency in ML libraries such as scikit-learn, TensorFlow, PyTorch, XGBoost, or LightGBM.
• Demonstrated experience in implementing anomaly detection algorithms and time series forecasting models (e.g., ARIMA, Prophet, LSTM).
• Good understanding of AI/ML algorithms like Random Forest, K-Means, Autoencoders, Graph Neural Networks (GNNs), and Louvain for anomaly detection, clustering, and time-series analysis.
• Experience in building and deploying cloud-native microservices (e.g., on AWS, Azure, GCP).
• Solid understanding of NoSQL databases like MongoDB, ElasticSearch storing ML data and time series.
• Messaging bus like Kafka or RabbitMQ
• Hands-on experience with model performance tuning, evaluation metrics, and real-world ML system optimization.
• Familiarity with ML lifecycle tools (e.g., MLflow, Kubeflow, SageMaker, Vertex AI).
• Understanding of containerization and orchestration (Docker, Kubernetes) for scalable deployment.
• Proficient in working with Git, CI/CD workflows, and Agile development methodologies.
• Experience with CI/CD tools such as Jenkins, GitLab CI, or GitHub Actions.
• Familiarity with Agile methodologies and ticketing systems (JIRA).

• Experience applying ML to wireless network optimization.
• Familiarity with federated learning or edge AI techniques to enable distributed ML across radio/access nodes.
• Understanding of online learning or reinforcement learning for dynamic network adaptation and control.

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field.

• "route" is used for session stickiness
• "careerSiteCompanyId" is used to send the request to the correct data center
• "JSESSIONID" is placed on the visitor's device during the session so the server can identify the visitor
• "Load balancer cookie" (actual cookie name may vary) prevents a visitor from bouncing from one instance to another
