[Hiring] Principal Software Engineer @HubSpot

Role Description

We’re looking for a Principal Software Engineer to play a defining role in this platform’s future. 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.

• Platform-scale ownership: Helps influence/drive technical direction across the entire AI context group. You’ll work across ingestion, processing, storage, sync, reliability, and intelligence surfaces.
• AI/ML Fluency: Our group is made of world-class experts in machine learning and AI and we help power AI experiences across HubSpot. The depths of your skill and expertise will be tested internally by our systems and externally by our partners.
• 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 acquisition: You move into unfamiliar areas quickly and meaningfully contribute—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.
