Staff Software Engineer, Backend - Breeze Assistant

We’re seeking a Staff Software Engineer to join a high-impact, new initiative within the Breeze Assistant team at HubSpot. Breeze Assistant is a fully conversational AI chief of staff designed specifically for Go-to-Market (GTM) teams. By integrating frontier AI capabilities with rich data from HubSpot and third-party applications, Breeze provides an AI assistant that fundamentally transforms team collaboration and productivity.

As a Staff Engineer on the Breeze Assistant team, you’ll do many things—and you likely already have experience doing some of them in the past. We are looking for people who:

• Have a long track record of experience delivering high-value, high-impact, cross-team projects. Staff Engineers are among the most senior individual contributors at HubSpot; they are leaders who continually strive to raise the bar for the engineering organization as a whole and are expected to help drive the product vision forward through strong collaboration skills and hands-on coding.
• Have extensive full-stack engineering experience, particularly with deep backend expertise. Proficiency with technologies like Java, Node.js, MySQL, Kafka, and cloud-native architectures is beneficial. We’re not necessarily looking for someone who is an expert in a specific technology, but someone who is well-versed in engineering principles and eager to leverage them to solve complex problems.
• Have direct experience building new user-facing products from scratch (0-1 experience), ideally involving complex integrations, data-rich applications, and collaborative user-facing platforms.
• Have hands-on experience or familiarity with Generative AI technologies (LLMs, Agents, RAG, etc.). Demonstrated interest or substantial experience working on AI-driven products is highly desirable.
• Demonstrate exceptional problem-solving, decision-making, and pragmatic engineering skills, balancing short-term needs with long-term technical vision.
• Thrive in high-risk, fast-paced environments and are comfortable operating without pre-existing structures, rapidly iterating, and adapting to evolving requirements.
• Have a strong grasp of secure, compliant application development practices, particularly around data privacy, governance, and API integrations.
• Committed to maintaining a hands-on approach to all technical aspects while providing leadership through effective collaboration with cross-functional teams and internal stakeholders.
• Provide strategic direction for major projects and drive technical decisions to solve challenging problems around persistent context, conversational interfaces, real-time collaboration, data governance, and application performance.
• Regularly mentor and teach engineers in their areas of expertise.
• Exhibit enthusiasm for building reliable, scalable systems.
• Can guide teams beyond the status quo; we need engineers who lead us beyond what we have, and towards what we can build, while fostering a shared vision of how to get there.
  

Preferred Qualifications:

• Prior experience developing desktop applications with frameworks like Electron, SwiftUI, or AppKit.
• Familiarity with HubSpot or other CRM platforms and integrations.
• Demonstrable interest or previous work in developing collaborative and conversational user experiences.
  

Join us in creating the AI assistant that defines the future of work for GTM teams!
