Senior Data Analyst

Analyst
Media Data & AI
Signal Clarity | Ho Chi Minh City (Hybrid) | Full-time | Senior (4-6 years)
About Signal Clarity
Signal Clarity is an independent technology company building intelligence infrastructure for brands and agencies. We design data platforms, dashboards and AI products - from social and competitive intelligence to media analytics - that turn fragmented marketing data into decisions.
We are now helping one of the leading global media agency networks in Vietnam bring its media data into a single, standardised data warehouse - the foundation for both its analytics and its next step: putting AI to work in daily operations through MCP (Model Context Protocol).
The Role
We are looking for a Senior Data Analyst who speaks both languages: data and media. You will split your time roughly 50/50 between two areas, and report to the Signal Clarity Leadership Team.
This is a hands-on role. You will write the SQL, design the data model and build the dashboards yourself - and you will be trusted to sit with agency teams, understand how they plan, buy and report media, and turn that into data they can rely on.
What you'll actually do
1. Client engagement (-50%): media data standardisation, warehouse & MCP
· Map and standardise media data across sources: platform and ad-server exports (Meta, Google, TikTok, YouTube, DV360 and others), media plans, buying and billing data, and agency trackers
· Define a common media taxonomy and naming convention - client, brand, campaign, channel, format, buy type, KPI - and the mapping rules to bring every source onto it
· Design the data model and build the data warehouse layers (raw → cleaned → business-ready) that serve all analytical needs
· Own data quality: validation rules, reconciliation of spend and delivery against plans and invoices, and clear data documentation
· Build the semantic layer and metric definitions that let AI agents query the warehouse through MCP - and test that the answers are correct
· Run workshops with agency stakeholders to gather requirements, explain data logic and agree definitions
2. Signal Clarity projects (-50%): data analysis & delivery
· Work as the data analyst on Signal Clarity's ongoing projects: analysis, dashboards and reporting for our clients and products
· Turn business questions into KPIs, data requirements and clear, evidence-based insights
· Build and maintain data pipelines and reporting automation, using Python and AI/LLM tools where they save time and reduce errors
· Work closely with our engineers and product team; review data logic and mentor junior team members as the team grows
What we're looking for
Must-have
· 4-6 years of experience in data analytics / business intelligence, with hands-on ownership of data models, dashboards and reporting
· At least 2 years working with media or advertising data - at a media agency, adtech/martech company, publisher, or a brand's media/marketing team
· Solid understanding of media metrics and how media is planned, bought and reported (spend, impressions, reach, CPM, CPC, CTR, VTR, conversions)
· Strong SQL and data modelling skills; experience building or maintaining a data warehouse
· Proficiency with a BI tool (Power BI, Looker Studio, Tableau or similar) and Python for data processing
· A data-quality mindset: you validate before you report and can explain why a number is right
· Confident working with stakeholders and presenting data logic to non-technical teams
· Good English (documentation, definitions and many stakeholders are in English) and native-level Vietnamese
Great-to-have
· Experience with cloud data platforms and tooling (BigQuery, Snowflake, dbt, Airflow or similar)
· Experience with advertising platform APIs or connectors (Meta, Google Ads, DV360, TikTok, Funnel, Supermetrics)
· Hands-on use of AI/LLM tools in analytics work; familiarity with semantic layers, MCP or text-to-SQL
· Experience designing data governance, master data or taxonomy standards across multiple teams
Why join
· Build the foundation.
Shape how a major media agency organises its data for analytics and AI - work that will be used every day
· Frontier AI in practice.
Put MCP and AI agents on top of real, well-governed data, not demos
· Variety.
Combine a large client engagement with Signal Clarity's own data and AI products
· Real influence.
Work directly with the Leadership Team in a small, senior team where your decisions matter
Compensation & benefits
· Competitive salary & benefits under Vietnam's law
· Hybrid working in Ho Chi Minh City, with client visits as needed
· Exposure to modern data stack and applied AI across media and marketing
