Principal Software Engineer - Customer Journey

We're looking for a Principal Software Engineer to help define and build the future of the Customer Journey at HubSpot. This is a deeply hands-on role focused on building intelligent, scalable systems that power onboarding, activation, and long-term customer success. You'll shape the architecture behind our Everboarding engine — a system that consumes millions of signals to predict next best actions, power surfaces like Global Home, and drive smarter growth and upgrade experiences.

Requirements

• Proven experience building and scaling distributed systems used by millions of users.
• Strong architectural instincts with a bias toward quick iteration, simplicity, clarity, and extensibility.
• Experience applying ML or GenAI in real products, with a healthy skepticism for “magic” and a bias toward trust and control.
• A track record of owning and delivering large, and complex cross-team initiatives.
• Comfort operating in ambiguity and turning it into clear plans and working systems.
• A hands-on mindset — you lead by building, not just by guiding.
• Strong product intuition and a focus on delivering real customer value.

Benefits

• Paid Time Off
• 401k Matching
