Technical Lead I, Backend, App Foundations

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.
