Senior Product Engineer - Backend (General / Flex)

About Dash0 Join Dash0 and help us define the future of observability. We are OpenTelemetry-native, building a delightful, simple, and AI-centric platform that eliminates vendor lock-in and meaningless toil. Shape a product that developers love—all with transparent pricing and cost-control built in. The Opportunity Dash0 is looking for a Senior Product Engineer to join one of our core backend teams — Intelligent Edge, Revenue Engineering, or Platform. You'll build everything from high-scale data pipelines and edge processing to the usage-based billing systems that power our business. This is a role where product thinking matters as much as engineering craft. You'll work at the intersection of massive-scale infrastructure and business-critical systems — processing billions of signals, querying terabytes of data, and ensuring accuracy in metering systems where real money is on the line. We need someone who cares about the end-user experience and the economic efficiency of every technical decision. What You'll Do Build highly scalable and resilient backend services in Go — from core ingestion pipelines and edge processing to usage-based billing infrastructure. Solve data engineering challenges at scale, including efficiently querying terabytes of data in ClickHouse and ensuring data accuracy in complex metering systems. Collaborate with product teams to evaluate the economic efficiency of technical designs and ensure maximum value for customers — you're a Product Engineer, not just a coder. Architect and evolve backend systems to handle billions of observability signals with low latency and high reliability. Define standards for code quality and testing, serving as a mentor to the team and ensuring systems remain maintainable as we scale. Drive best practices for Go services and OpenTelemetry distributions across the engineering organization. What You Bring Extensive experience building and scaling distributed backend systems, primarily in Go. Familiarity with high-performance data stores like ClickHouse or messaging systems like Kafka. A product mindset — you care about the end-user experience and think about the business impact of your technical decisions. Strong understanding of observability principles, including experience with OpenTelemetry and Prometheus. Experience designing for reliability, scalability, and operational excellence in production environments. A collaborative approach to engineering — you mentor others, share knowledge, and raise the bar for the team. Nice to Have Experience with Java in addition to Go. Background in billing, metering, or revenue engineering systems. Experience in a high-growth, venture-backed startup environment. Why Dash0 This is a unique opportunity to help build a generational company. Dash0 is backed by top-tier investors including Balderton Capital, Accel and Cherry Ventures and led by a founding team with decades of experience in observability. We're in the middle of a massive growth phase after our Series B — and we're just getting started. If you're looking for a place where a great product meets great people, where momentum is real and your impact is visible from day one — this is it. What we offer: Competitive salary & meaningful equity participation — you'll own part of what you're building Flexible, remote-first work environment with offices in New York, Amsterdam, and Munich €60/month phone & internet allowance Location-specific benefits Collaborative, fast-moving team culture with a builder mindset Clear path for career growth and development Direct access to founders and leadership
