Project Support & Collaboration:

• Review product release artifacts, assist with deployments, and collaborate with Application Management teams.

• Assess data-oriented product testing scope, define timelines, and develop execution roadmaps.

Automation & Advanced Analytics:

• Explore low-code libraries (e.g., Great Expectations, Sweetviz, Pandera) for automated data profiling.

• Leverage no-code tools like KNIME for effective data analytics.

• Familiarized with LLMs and machine learning techniques for data-driven automation initiatives wherever applicable (not mandatory but a plus)

Qualifications:

• Educational Background: Bachelor’s or Master’s degree in Engineering, Information Science, or a related field, with strong hands-on experience in data manipulation, analysis, and programming using Python.

• Experience: 6–8 years of experience in a data-driven role, with proven expertise in analytical programming, data wrangling, and data analysis.

• Financial Knowledge: An MBA (Finance), CFA Level 1/2, or CIPM certification is a significant plus.

• Detail-Oriented & Communicative: Exceptional attention to detail and strong communication skills, with the ability to collaborate effectively with global teams, ensuring alignment on project goals and deliverables.

• Self-Starter: A proactive mindset with the ability to work independently, adapt quickly to new challenges, and thrive in a fast-paced and evolving environment.
