About the role

Principal Product Engineer at Tilt (f.k.a. Delphia), a remote-friendly YC-backed company building InvestOS and Tilt as the open platform for AI-native investment methodologies.

Responsibilities

  • Own major product areas from architecture through production, shipping features that customers use every day.
  • Build across the stack—from AI orchestration and backend services to APIs and frontend experiences.
  • Work closely with designers and AI/ML researchers to turn ambitious product ideas into fast, reliable software.
  • Design systems that scale while remaining simple enough to evolve as the product changes.
  • Make thoughtful engineering tradeoffs between speed, quality, and long-term maintainability.
  • Identify technical bottlenecks before they become organizational bottlenecks.
  • Raise the engineering bar through technical leadership, code reviews, mentoring, and a bias toward pragmatic execution.
  • Continuously improve how we build by leveraging AI throughout development, testing, debugging, and deployment.

Qualifications

  • Experience building products, not just software, and understanding the difference.
  • Strong engineering fundamentals and comfort across the stack.
  • Ability to decompose messy, ambiguous problems into simple, maintainable systems.
  • Understand when to invest in architecture vs. shipping.
  • Clear communication of technical ideas with designers, researchers, and founders.
  • Ownership mindset and ability to work from first principles.
  • Belief in AI transforming software development and active use of AI in workflow.
