Job Description

We are looking for a Senior Product Engineer to join one of our core backend teams---building everything from high-scale data pipelines and the Intelligent Edge to the usage-based billing systems that power our business.

The Challenge You'll Tackle:

• Build for Massive Scale: Whether it's processing billions of signals at the Edge or architecting core ingestion pipelines, you will build highly scalable and resilient backend services in Go.
• Solve Data Engineering Puzzles: You'll tackle challenges like efficiently querying terabytes of data in ClickHouse or ensuring data accuracy in complex metering systems where "money is involved".
• Bridge Product and Engineering: You'll be a true Product Engineer, not just a coder. You will collaborate with product teams to evaluate the economic efficiency of technical designs and ensure we deliver maximum value to customers.
• Foster Technical Excellence: You'll define standards for code quality and testing, serving as a mentor to the team and ensuring our systems remain maintainable as we scale.

What Success Looks Like (and How You'll Get There):

• Within 1 week: You'll have shipped your first piece of production-ready code.
• Within 3 months: You'll have shipped significant backend features---such as new aggregation capabilities for the Edge or improved usage dashboards for billing.
• Within 6 months: You'll be a go-to expert for key areas of our backend, mentoring others and driving best practices for our Go services and OpenTelemetry distributions.
• Within 12 months: You'll have played a pivotal role in evolving our backend architecture to support the next generation of Dash0 features, helping us stay ahead in the observability market.

We're looking for someone who:

• Has extensive experience building and scaling distributed backend systems, primarily in Go (Java is a plus).
• Is familiar with high-performance storage like ClickHouse or messaging systems like Kafka.
• Has a "product mindset"---you care about the end-user experience and the economic efficiency of your code.
• Lives and breathes Observability and is familiar with OpenTelemetry and Prometheus.

Why You'll Love Working at Dash0

• Strategic Impact: See your decisions directly shape the trajectory of a fast-growing platform.
• Brilliant Team: Work with high-trust, high-talent engineers who value learning and psychological safety.
• Remote & Flexible: Work from anywhere in Europe with a competitive salary and equity package.
