Meet the Team: CS on Service Hub - Flywheel Group

The Flywheel Group supports HubSpot's vision to build a product that powers its own teams - "HubSpot runs on HubSpot." This team builds the core experience that enables Customer Success and Customer Service reps to operate efficiently within the HubSpot platform.

Our work focuses on creating the next generation of rep experiences:

• A central, intelligent interface that supports reps with contextual data and actionable alerts
• Tools that help identify high-impact opportunities and drive consistent execution
• AI-powered experiences to eliminate repetitive tasks and enhance workflows

The features built by this team don't just empower HubSpot's internal teams - they often evolve into externally available functionality for our customers, especially as we grow upmarket.

What's the day-to-day like?

• End-to-end ownership of new features, often initiated by engineers themselves
• Collaborating closely with CS reps to understand needs and iterate rapidly
• Building backend systems (Java required), while contributing across the stack when needed (React experience preferred)
• Partnering with data scientists to surface insights and build intelligence into workflows
• Embracing a "ship to learn" mindset - using experimentation and feedback to guide development
• Operating in a high-trust, high-autonomy environment where engineers are expected to take initiative

You may be a great fit if you:

• Have strong backend experience and a willingness to work across the stack
• Think like an owner and love learning about the business
• Care deeply about the impact of what you're building and the problems you're solving
• Are comfortable working closely with users (CS reps) and iterating quickly based on feedback
• Thrive in a fast-moving environment with a high degree of autonomy and ownership
• Are excited about leveraging AI and data science in real-world, practical applications
• Hold yourself to a high standard of code quality and take accountability for delivery
• Are comfortable navigating ambiguity and contributing to shaping the team's direction

Why join this team?

• Meaningful Impact: The features you build will directly support HubSpot's CS teams - and scale to customers.
• AI-Powered Innovation: Partner with data scientists to drive intelligent workflows.
• Engineer-Led Problem Solving: Engineers are encouraged to propose and drive initiatives.
• Growth-Focused Culture: Fast iteration cycles, regular feedback, and space to experiment.
• Psychological Safety: The team iterates quickly in a safe, collaborative environment designed for learning.

If you're excited to build high-impact, AI-powered tools that serve both internal and external users - and you love solving complex problems alongside a collaborative team - we'd love to hear from you.
