At HubSpot, we’re building a world-class CRM, Marketing, Sales, and Services platform that helps small and medium-sized businesses grow better. More than 250,000 customers around the globe rely on our products, and we’re continuing to invest deeply in engineering to scale and innovate.
We’re looking for a Senior Software Engineer to join the Data Sync Engine team, the foundation of HubSpot’s Data Hub. This team is responsible for building and maintaining Data Sync: a best-in-class, real-time two-way sync platform that connects external SaaS tools with HubSpot’s CRM. On top of that, the team is also working on Data Studio: a brand new data ingestion platform, from where data can be combined, enhanced and activated upon, which is now more relevant than ever in the current AI age.
About the Team: Data Sync Engine
Data Hub is one of the fastest-growing parts of HubSpot’s ecosystem. It helps organizations stay productive by keeping their data consistent across tools like Salesforce, Microsoft Dynamics, and Zendesk.
At the core of both Data Sync and Data Studio is a flexible, high-performance engine powered by Haskell. This engine processes large volumes of data changes across systems, ensures accuracy, and provides customers with a real-time view of their data. The sync behavior is driven by a composable domain-specific language (DSL) interpreted at runtime.
You’ll be part of a team of experienced engineers who care deeply about functional programming, quality, and solving complex distributed system challenges.
In this role, you’ll:
- Design and implement platform capabilities that power both the Data Sync and Data Studio experiences.
- Contribute to the Haskell-based sync engine and evolve its DSL for new use cases.
- Build scalable infrastructure and performance-critical features across a distributed worker fleet.
- Develop monitoring and observability tools to ensure platform health.
- Invent reusable abstractions that extend the platform to support more SaaS integrations.
- Collaborate with teams across app integrations, product, and design.
- Work in a high-trust environment with product ownership and autonomy.
We’re looking for people who:
- Are proficient in Haskell (or excited to deepen their expertise).
- Have experience with distributed systems and data pipelines.
- Think in systems and care about correctness, reliability, and performance.
- Enjoy solving real customer problems and delivering outcomes.
- Balance engineering quality with product delivery.
- Take initiative and ownership of complex projects.
- Are comfortable analyzing trade-offs and making empathetic decisions.
What’s in it for you?
- Join an experienced and passionate team of functional developers.
- Significant autonomy in a high-impact, product-focused engineering culture.
- The opportunity to contribute to an advanced Haskell system, in production today.
- The ability to shape how customers connect their business tools in a rapidly growing space.
Tech Stack
- Primary language: Haskell
- Other technologies: Java, Go, Kafka, Kubernetes, Vitess, HBase, internal developer tools
- Platform: Microservices running in Kubernetes, built for scale and reliability
At HubSpot, we know the right candidate might not check every box. If this role excites you, we encourage you to apply. We’re committed to building a diverse, inclusive, and supportive workplace where you can do your best work.
