The Opportunity: Principal Software Engineer

This is a high-level individual contributor engineering role. The Principal Software Engineer leads innovation and sets the technical standard for the entire engineering team. This person is deeply AI-native — not just using AI tooling, but actively championing and evolving AI-driven development workflows across the engineering organization.

LifeLoop is an AI-native engineering organization. All roles are expected to be proficient with the latest AI development tooling and workflows, and to actively keep pace with rapid advancements in this space. The engineering team is organized into focused squads operating on a Kanban model, with a culture of spec-driven development, pragmatic execution, and continuous improvement.

What can you expect the role to look like:

  • Lead development of the most complex products and features on the LifeLoop platform
  • Identify and drive adoption of emerging AI tools and workflows that improve how the team builds software
  • Serve as a technical coach to both engineering leads and junior engineers — helping the team level up technically and in their use of AI-assisted development
  • Contribute to the engineering playbook and continuously evolve how the team works
  • Operate with a pragmatic coaching style — hands-on, not just advisory
  • Set and uphold engineering quality standards across the codebase
  • Collaborate with product and leadership to shape the technical direction of the platform
  • Drive spec-driven development practices and ensure technical specifications are clear, complete, and actionable

AI Expectations:

This role is expected to be a visible champion of AI-native development. Proficiency with tools like Claude Code, and similar AI coding assistants is required. Willingness to experiment with new AI tooling, document learnings, and raise the entire team’s capabilities is essential. The Principal Software Engineer should be the person the team looks to for guidance on how to best leverage AI in their day-to-day workflows.
