A Research Analyst at C5i is responsible for managing the end-to-end lifecycle of market research projects. This includes everything from initial project scoping and methodology design to data analysis, synthesis, and final client reporting. You will actively execute both quantitative and qualitative studies, often utilizing modern agile research platforms to deliver high-quality insights under tight timelines.

Collaboration is a core component of this role. You will work closely with onshore and offshore teams, ensuring that project deliverables are aligned with client expectations. You will act as a trusted advisor to client marketing, brand, and creative teams, responding to ad-hoc data requests and synthesizing disparate data sources into clear, actionable, and visually compelling presentations.

Additionally, you will be expected to maintain meticulous documentation of research processes and best practices. You will manage vendor relationships, coordinate with external media or research agencies, and provide regular status updates to your leadership team. The role demands high agility, as you will frequently pivot between structured, long-term brand tracking studies and rapid-response market intelligence requests.

To be competitive for the Research Analyst position at C5i, you must present a strong combination of technical capability, analytical curiosity, and polished communication.

• Must-have skills – Strong foundation in market research methodologies (both qualitative and quantitative), experience with custom data analysis, and proficiency in MS Excel and PowerPoint. Excellent written and verbal communication skills are mandatory, as is the ability to manage multiple projects simultaneously.
• Nice-to-have skills – Experience with agile research platforms (such as Toluna, Zappi, or Qualtrics), familiarity with syndicated data sources, and basic knowledge of data visualization tools like Tableau or Power BI.
• Experience level – Typically requires a Bachelor's degree or an MBA in Marketing, Market Research, Business Analytics, or a related field. Prior experience in a research agency, consulting firm, or corporate market research department is highly valued.
• Soft skills – Exceptional organizational skills, high attention to detail, a calm demeanor under pressure, and the ability to collaborate effectively with cross-functional and global teams.
