The Data Platform product line builds the foundation for an AI-powered CRM that powers customer engagement and front-office workflows through unified, trustworthy, and real-time customer data.

We Operate At a Massive Scale

Our core CRM platform processes billions of transactions daily.
We manage petabyte-scale data systems.
The platform is not a single database, but a full ecosystem of ingestion pipelines, storage layers, synchronization systems, AI/ML data infrastructure, and developer frameworks to power the next generation of intelligent, extensible CRM features.

About The Role

We’re seeking a Principal Software Engineer to play a pivotal role in shaping the future of this platform. This individual will have a proven track record of delivering projects with significant product-line or company-level impact, often in ambiguous or complex technical environments. They move across domains with ease, challenge existing assumptions, and redefine what’s possible through deep architectural thinking and strong execution.

At HubSpot, Principal Engineers are not only technical strategists but builders: trusted with end-to-end delivery of complex initiatives. This engineer will help shape the technical direction across the entire Data Platform, comprising 180 people, influencing decisions that directly tie into HubSpot’s broader CRM, extensibility, and AI/ML product strategy.

Key Expectations

Platform-scale ownership: Helps influence/drive technical direction across the entire Data Platform product line, not just one group or team. You’ll work across ingestion, processing, storage, sync, reliability, and intelligence surfaces.
Hands-on, high-leverage contributor: You ship software- not just prototypes. We expect deep technical engagement in the systems you influence, including ownership of large, high-impact initiatives.
Distributed systems expertise: You’ve operated and evolved large-scale, fault-tolerant, cost-efficient systems. You’re comfortable scaling across billions of events per day and guiding design around availability, throughput, and latency.
Architectural leadership: You define and drive reusable platform patterns across ingestion, processing, quality, sync, and observability.
Strategy alignment: You align platform architecture with HubSpot’s CRM, AI/ML, and extensibility goals, ensuring infrastructure enables product evolution- not constrains it.
Technical mentorship & leadership: You’re recognized as a mentor and multiplier. Others seek your input for design reviews, incident postmortems, and architectural bets.
Cross-functional influence: You partner with product and engineering leadership to define strategy, scope opportunities, and execute for product-line-wide outcomes.
Rapid domain fluency: You move into unfamiliar areas quickly and make meaningful contributions- whether it’s a new tech stack, domain model, or organizational challenge.
Internal and external impact: You elevate HubSpot’s brand, help attract and retain senior talent, and share your knowledge across the company.
