Technical Lead I, Backend, App Foundations

POS-12191

At HubSpot we are building a customer platform that helps millions of organizations grow better. To do this we need a flexible extensible foundation that allows our own engineers third-party developers and natural language vibe coders alike to build seamless integrations and personalizations natively into HubSpots platform.

We are looking for a Backend Tech Lead to join the App Foundations team. This is a high priority role where you will lead a small team of engineers responsible for the packaging and distribution container for every integration across the entire HubSpot ecosystem. You will be moving the needle from a code-only extension model to a future where agents and natural language can personalize and extend the HubSpot product.

In this role you will:

• Lead by example: Serve as a Player-Coach balancing technical mentorship for a small team of engineers with high-level system design and hands-on execution.
• Architect the future: Own the data model and packaging systems that allow first and third-party extensions to plug into HubSpots platform.
• Solve complex systems problems: Reason through before and after architectural shifts that impact a wide surface area of the HubSpot product.
• Drive AI-readiness: Build the underlying structures and guardrails that enable AI agents to reason about and build extensions and integrations on behalf of users.
• Collaborate broadly: Partner with teams across the business to ensure that our platform decisions enable success for our global customer and developer community.

We are looking for people who have:

• Technical Leadership experience: Ideally you have previously served as a Tech Lead or lead engineer in past roles.
• Expertise in System Design: You have a proven ability to design and scale complex distributed systems.
• Proficiency in our stack: Strong experience with Java and MySQL and hands-on use of agent-assisted coding tools will enable candidates to hit the ground running.
• Integration domain knowledge: Experience working on integration platform problems extensibility frameworks or developer platforms (either internally or externally facing).
• A Collaborative mindset: You enjoy working cross-functionally and understand that your technical decisions affect thousands of other developers.

Why this team

The App Foundations team is part of a cohesive pod in our Cambridge office. You will join a larger group of long-tenured engineers who value in-person collaboration and mentorship. While HubSpot is remote-friendly this specific team maintains a hybrid presence in Cambridge to foster deep technical culture and brainstorming. We are happy to relocate the right candidate to join us in person.
