Technical Lead I, Backend, App Foundations
Directly building AI-readiness for AI agents and natural-language driven extensions; role expects use of agent-assisted coding tools and supports agent-driven development workflows.
About the Role
Lead a small backend engineering team on HubSpot's App Foundations to design and build the packaging, data models, and distribution systems that enable first- and third-party integrations and prepare the platform for natural-language and agent-driven extensions. Balance hands-on execution, system design, and technical mentorship to move the product from code-only extensions toward AI- and agent-enabled extensibility.
Job Description
Role
HubSpot is hiring a Backend Technical Lead for the App Foundations team to own the packaging and distribution container for integrations across the HubSpot ecosystem. The role is a hands-on “player-coach” position responsible for system design, execution, and mentoring a small team while driving architectural shifts to enable agent- and natural-language-driven extensions.
Key Responsibilities
- Serve as a player-coach: provide technical mentorship, lead by example, and contribute hands-on to engineering work.
- Architect and own the data model and packaging systems that allow first- and third-party extensions to plug into HubSpot’s platform.
- Design and execute large-scale architectural changes that affect a wide surface area of the product and integrations.
- Build AI-readiness: develop structures and guardrails enabling AI agents and natural language workflows to reason about and construct extensions and integrations.
- Collaborate across product and engineering teams to ensure platform decisions support developers and customers globally.
Requirements
- Prior technical leadership experience (Tech Lead or lead engineer roles).
- Proven ability to design and scale complex distributed systems and system architectures.
- Proficiency with Java and MySQL; familiarity with agent-assisted coding tools is expected.
- Experience with integration platforms, extensibility frameworks, or developer platform problems (internal or external).
- Strong cross-functional collaboration, communication, and mentorship skills.
Team & Location
- The App Foundations team operates as a cohesive pod with a hybrid presence in HubSpot’s Cambridge office; the role emphasizes in-person collaboration and mentorship.
- HubSpot is remote-friendly overall, but this team maintains a hybrid, Cambridge-focused presence and can relocate the right candidate.
- In-person onboarding and periodic in-person product events are required for employees joining Engineering and Product roles.
Notes
- The description focuses on technical leadership, backend system design, and preparing the platform for AI/agent-driven extension workflows. Boilerplate company and equal-opportunity language have been omitted.
