• Collaborate with cross-functional teams to translate business objectives into robust, scalable engineering solutions.

• Mentor and guide engineers across multiple levels, fostering technical growth and high-quality delivery.

• Drive initiatives that improve developer productivity, system observability, and operational excellence.

What You'll Need:

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

• 12+ years of professional software engineering experience, with at least 2+ years in a Staff- or Principal-level technical leadership role.

• Proven success designing and delivering high-performance, distributed systems or large-scale workflows and services.

• Strong proficiency in one or more modern programming languages (e.g., Java, Kotlin, Python).

• Proficiency in Terraform and Jenkins

• Deep understanding of system design, architecture patterns, and cloud-based deployment (AWS, GCP, or Azure).

• Experience integrating with or supporting ML pipelines, APIs, or data-driven applications.

• Demonstrated ability to drive cross-team technical initiatives and influence architectural decisions.

• Strong communication and collaboration skills, with the ability to partner effectively across engineering, product, and data science teams.

Bonus:

• Experience in e-commerce or retail.

• Experience with modern MLOps.

• Exposure to front-end or product-facing integration of ML features.

• Experience with AWS Sagemaker and other ML platform tooling.

• Experience working with large distributed datasets and ML feature engineering.
