Senior BI Engineer

Guardio is one of the fastest-growing companies in consumer cybersecurity - we’ve doubled revenue four years running, passed $150 million in ARR, and now protect over a million people, at a moment when AI has made scams more convincing than ever.

AI has democratized cybercrime: scams that once required sophisticated hacking teams are now cheap, personalized, and everywhere.

Traditional security wasn’t built for this - so we’re building it, protection that sees the person, connects all the dots - and stop attacks and scams wherever vector they come from.

And honestly, we all feel here - it’s just the beginning!

Let's cut to the chase. What's the job?

At Guardio, the Growth team moves fast to turn visitors into protected, paying users. We work in quick cycles: idea → build → A/B test → learn → iterate. We are looking for an experienced Fullstack Product Engineer who loves owning features from the first line of code to live production, and using data to see what works.

What you'll do

• Build and maintain robust ETL/ELT pipelines that transform raw data into production-ready datasets used for threat detection, risk investigation, and customer-facing product features.
• Design and develop scalable, maintainable data models in dbt (layered architecture, reusable components, documentation) supporting cybersecurity use cases such as detecting suspicious patterns, emerging risks, and behavioral anomalies across users and online platforms.
• Take ownership of our cybersecurity data infrastructure (foundational datasets, governance, and observability) - maintaining, improving, and enriching it to support reliable, high-scale data delivery to detection and protection systems.
• Orchestrate and monitor workflows with Airflow (scheduling, dependencies, retries, alerting, SLAs).
• Partner with Security Analysts, Data Science, Research, and Product teams to understand their needs and translate them into reliable pipelines and datasets that power threat detection capabilities and customer protection.
• Ensure data quality and reliability through testing, validation, and monitoring for critical security datasets.

What we're looking for

• 5+ years in BI Development / Analytics Engineering / DWH Development roles.
• Expert SQL and strong experience with data modeling concepts (e.g., dimensional modeling, facts/dimensions, modular design).
• Experience with ETL/ELT tools and modern data stacks (orchestration, transformations, CI/testing, monitoring).
• Strong communication skills and a track record of delivering data solutions that power real product or operational outcomes.
• Experience building data pipelines that feed production systems, detection engines, or operational data products.
• Experience with cloud-based data technologies (GCP/AWS/Azure) and modern warehouses (BigQuery/Redshift/Snowflake).
• Experience in Python is an advantage.
• Familiarity with web technologies and protocols (HTTP, DNS, HTML, etc.) is an advantage.
• Cybersecurity or security data experience is an advantage.
• Hands-on experience with dbt and Airflow in production environments is an advantage.
