Description du poste

We love the magic of memory keeping

At Journi, we're on a mission to build the world's most-downloaded printing app.

With over 10 million users worldwide, we help people turn their favorite moments into beautifully designed Photo Books and Prints. Our smart AI makes the process fast, simple, and joyful, so our users can spend less time editing and more time reliving their best stories.

We're looking for a Senior Data Engineer to own our data warehouse and ETL pipelines, and make our data something the whole company can trust. You'll report directly to our CTO, work closely with our data analysts, and play a key role in shaping how data powers decisions across Journi!

What you'll do

• Own the architecture of our Redshift warehouse and ETL pipelines, and make it the trusted source for core business data. As our first dedicated data engineer, you'll shape how our data architecture evolves.

• Work directly with Marketing, Finance, Product, and Customer Happiness, together with our data analysts, to turn their questions into the right data models and connect new data sources.

• Implement data transformations that support changing key metrics definitions, such as revenue attribution.

• Build data marts that keep dashboards fast, and an internal MCP server that gives AI agents access to reliable, well-documented data.

• Keep our pipelines reliable, with monitoring that alerts teams when data is late or incomplete.

• Give and receive feedback, and bring your own expertise to the team.

Your bag of tricks

• 5+ years in data or backend engineering, including 2+ years owning a data warehouse or ETL pipelines end-to-end.

• Excellent SQL and Python, with strong experience optimizing query performance on columnar warehouses like Redshift, Snowflake, or BigQuery.

• You've built reliable pipelines from production databases and third-party APIs, with testing, monitoring, and alerting; you handle customer data with care, and you own it when they break.

• You know dimensional modeling and the trade-offs between data tools and architectures, including when to keep things simple.

• Solid analytics understanding: you know how metrics like revenue and conversion are defined and used, and why numbers differ between data sources.

• You communicate clearly. You explain technical decisions, trade-offs, and data limitations to analysts, marketing, finance, and leadership, set expectations, and push back when data quality is at risk.

• You are permitted to work in the EU/Austria (OR have a university degree in Data/Computer Science, which is required to apply for an Austrian work permit)

• You are able to relocate to / based in Vienna - the world's most liveable city!

Nice-to-haves

• Experience working across multiple data platforms at scale: connecting product analytics, backend data, and marketing sources to close gaps and improve data quality

• Experience running workshops with leadership in a startup or scale-up context
