Medior / Senior Data Analytics Engineer

We are looking for a technical, independent, and curious data analytics engineer to partner with our analytics lead and help scale the way Ventrata uses data both internally and as a product offering. You will be managing the backend of our analytics stack: building Dataform models, connecting data sources, and helping with PostHog and GoodData dashboards that fuel insights across our organization and client base.

If you are someone who loves writing code, building scalable data pipelines, and enjoys turning chaos into structure this is your playground. You will be shaping analytics foundations that power everything from product decisions, experiment evaluation and much more.

What We Are Building (Our Analytics Stack)

Ventratas analytics platform is still a greenfield environment, a space where great ideas and technical innovation are not just welcome but essential. Our current analytics setup includes:

• BigQuery: our central analytical data warehouse
• PostHog: for product analytics and A/B testing (we are expanding this into a client facing feature)
• GoodData: for internal business intelligence and dashboarding
• Dataform: for building and maintaining data models inside BigQuery
• PostgreSQL: our core backend database powering all Ventrata applications
• Keboola: for ingesting external data sources (e.g. Xero accounting data) into BigQuery

Google Tag Manager (GTM) and Google Analytics 4 (GA4): for managing client side tracking and analytics integrations.

• Experience: 3+ years in data analytics or data engineering, with a focus on building and maintaining data pipelines in cloud data warehouses (BigQuery, Snowflake, etc.).
• SQL Expertise: Proficient in SQL and able to write modular, maintainable queries. Familiarity with SQL-based transformation frameworks like Dataform or dbt is a must.
• BI & Data Modeling: Experience with business intelligence tools (e.g. GoodData, Looker, Power BI, Tableau). Ability to design logical data models, define clear metrics, and develop insightful dashboards.
• Communication: Excellent communication and documentation skills to be able to explain complex data concepts to both technical and non technical stakeholders clearly.

Self-Driven: High degree of ownership and independence. Proven ability to prioritize tasks, adapt to changing requirements, and meet deadlines. We are a startup, so an agile mindset and enthusiasm for continuous learning are crucial.

• Experience with product analytics tools like PostHog, Mixpanel, or Amplitude.
• Knowledge of web analytics and tracking instrumentation (GTM, GA4).
• Experience connecting and integrating external data sources (e.g., via Keboola).
• Previous exposure to backend systems or experience writing queries directly on production replicas (PostgreSQL).

Experience supporting client implementations or doing analytics in a SaaS environment.

What Success Looks Like (First 90 Days)

• Improved our data models: Refactored key parts of our Dataform models in BigQuery to boost performance and maintainability, with dependencies documented and data quality tests in place to ensure accuracy.
• Expanded our analytics data: Integrated a new external data source (for example, pulling Xero accounting data via Keboola) and joined it with our internal datasets, resulting in a unified dashboard for finance metrics.

Gained product domain knowledge: Built a strong understanding of Ventrata’s core products.
