Senior Data Analyst

Efficient Studio is a Mar Tech & AI-Automation consultancy on a mission to turn data chaos into clarity and clarity into growth. We're a lean, senior-heavy team that partners with Indonesia's leading brands to eliminate guesswork and drive decisions with real data. Fast-moving, no-fluff, high-impact.

We're looking for a Senior Data Analyst who can do it all, pull and process raw data, extract sharp insights, and walk into a client boardroom and tell a story that drives action. This isn't a back-room analytics role. You'll be client-facing, consultative, and expected to translate complex data into decisions that move the needle for marketing teams.

• Build and maintain dashboards in Looker Studio, Power BI, and/or Tableau that stakeholders actually use
• Translate data into clear, compelling presentations. You'll regularly present to marketing leads and C-level clients
• Identify trends, anomalies, and opportunities in marketing performance data (paid, organic, CRM, retention, etc.)
• Work closely with Measurement Specialists and Data Engineers to ensure data integrity before analysis
• Develop frameworks and templates that improve how we, and our clients, think about data
• Handle multiple B2B client accounts simultaneously, managing timelines and deliverables like a pro

Must-Have:

• 4–5 years of experience in data analysis, preferably with exposure to marketing data (paid media, CRM, retention, funnel analytics)
• Strong proficiency in SQL, you can write complex queries without breaking a sweat
• Hands-on experience building dashboards in Looker Studio
  , Power BI
  , and/or Tableau
• Proven ability to extract and communicate insights, not just report numbers
• Excellent presentation and slide-making skills, your decks are structured, visual, and tell a story
• Experience handling B2B client relationships with professionalism and confidence
• Sharp analytical and critical thinking, you question assumptions and dig until you find the real answer
• Open to feedback, able to iterate fast, and never precious about your work

Nice-to-Have:

• Background in a marketing agency, consultancy, or Mar Tech environment
• Familiarity with GA4, Apps Flyer, or CRM platforms (understanding of the data sources is a big plus)
• Exposure to Python or R for more advanced data processing
• Experience with Big Query or cloud data warehouses

• Competitive salary based on experience
• Hybrid work setup, 2 to 3 days WFO in Jakarta (office or client site)
• Direct access to diverse, complex datasets from Indonesia's top brands
• A culture that rewards sharp thinking, fast execution, and intellectual curiosity
• No bureaucracy, your ideas get heard and implemented

• Come from a marketing background and understand what metrics actually matter to a CMO
• Love the moment when a messy dataset finally reveals a clear story
• Can simplify complexity into a slide a CEO can act on in 5 minutes
• Are a builder at heart, you don't wait for perfect conditions, you make it work
