About the Role

We are looking for a Head of Engineering to lead the technical future of Mantle. This is a foundational role for a hands-on engineering leader who wants to build not just a product, but an engineering team and culture from the ground up. You will work side-by-side with the founders to turn an ambitious vision into a consumer product that families trust with some of the most important parts of their lives. In the early days, you'll write a meaningful share of the code yourself while also hiring the team, setting the technical direction, and establishing how we ship.

Responsibilities

  • Hire, develop and lead a small, high-performance team of engineers across full stack, AI and mobile.
  • Own the architecture and infrastructure for our consumer web and mobile applications and the AI agent at their core.
  • Establish a culture of urgency, ownership, sound judgment and strong execution.
  • Define how engineering plans, prioritizes, communicates and delivers alongside product and design.
  • Build the testing, monitoring, security and privacy practices that let families trust Mantle with sensitive information.
  • Make modern AI coding tools and agents a core part of how the team builds.

Requirements

  • 10+ years of high-performance software development experience, including 3+ years leading engineering teams.
  • Track record of shipping consumer products end-to-end, from concept to production, in a startup or high-growth environment.
  • Strong proficiency with modern full stack technologies (e.g. React, Node.js) and cloud infrastructure on AWS.
  • Hands-on engineering ability and willingness to go deep on any part of the stack.
  • Expert in hiring and developing strong technical talent.
  • Strong technical judgment, including the ability to make good tradeoffs under uncertainty.
  • Early-stage startup experience, ideally having built an engineering function from the ground up.
  • Experience building both web and mobile applications.
  • Experience shipping AI-powered or LLM-based products to real users.
  • Strong product sense and a clear instinct for what matters in a startup.
  • Has partnered with founders on company priorities, roadmap, and execution.
  • Experience with FinTech or products handling sensitive personal data is a plus.

About the Company

  • We’re building an AI agent to help families support their aging parents.
  • Over 40M “sandwich generation” Americans currently manage their parent’s affairs. Keeping mom/dad safe and supported is like a second job: it’s time-consuming, stressful and on top of their already busy lives. We believe that managing our parents’ affairs should feel under control, easier and lower stress.
  • Co-founded by serial entrepreneur partners including Ted Zagat, who sold his previous businesses to Slack and Google.
