Role overview

Join Hopper as a Staff Backend Software Engineer (Full Remote). You’ll use AI to build and ship features quickly in a low-process environment with senior engineers. You’ll drive decisions and own features end-to-end, with a strong emphasis on scalable backend systems and product-focused engineering.

Key missions

  • Improve the codebase to enhance efficiency for both humans and AI agents.
  • Architect scalable solutions and foundational patterns to launch new partner experiences efficiently.
  • Collaborate across teams using asynchronous feedback, while giving and receiving feedback to drive decisions and growth.

Responsibilities / what you’ll do

  • Direct AI agents and automated workflows to build and maintain complex systems, including knowing when to intervene.
  • Deliver results by rapidly onboarding to and contributing in unknown codebases.
  • Clearly explain not only solutions, but also the rationale and tradeoffs.
  • Design guardrails and feedback loops that keep AI-assisted development productive and reliable.
  • Apply product thinking by grounding quality and architecture in the customer experience.

Requirements

  • Mastery-level willingness to learn and/or experience with distributed system development in Scala.
  • Ability to design and implement guardrails/feedback loops for reliable AI-assisted development.
  • Strong communication and product-oriented architectural judgment (quality anchored in customer experience).
  • Experience working with AI automation/agents to build and maintain complex systems.

Nice-to-haves

  • Experience building scalable backend patterns for partner-facing experiences.
  • Demonstrated comfort in a low-process, high-ownership environment.
