Technical Proficiency

This area is the foundation of the role. You will be evaluated on your mastery of data tools, languages (such as SQL, Python, or Java), and your understanding of data structures. Strong performance involves not just knowing the tools, but understanding why you chose them for a specific problem.

This includes working closely with product managers and other engineers to define requirements, architect solutions, and ensure that the final product meets the highest standards of reliability.

You will often be embedded in project teams where you will act as a subject matter expert. This involves not only coding and architecture but also proactive communication with stakeholders to ensure that technical implementations are aligned with business goals. You will be expected to identify potential risks early in the development lifecycle and suggest proactive solutions to mitigate them.

• Must-have skills – Advanced proficiency in SQL, experience with ETL/ELT pipeline development, and a strong understanding of database management systems.
• Nice-to-have skills – Experience with cloud platforms (AWS, Azure, or GCP), containerization technologies like Docker or Kubernetes, and familiarity with data governance and compliance standards.
• Experience level – We value a mix of theoretical knowledge and hands-on experience, typically looking for candidates who have demonstrated the ability to own and deliver data-centric projects.
