London, UK, United Kingdom hati Full time

At hati, we’re on a mission to fix modern dating. Swiping, ghosting, endless texting—dating apps promised connection, but they’ve left us lonelier than ever. We’re here to change that.


hati is built on a simple idea: no texting, no fluff—just 5-minute voice calls to help people connect meaningfully. We’re in BETA with over 750 users, and we’re ready to scale. To get there, we need a Founding Engineer who’s as obsessed with building products as we are with fixing the loneliness epidemic.

What You’ll Do

As our Founding Engineer, you’ll take ownership of the technical side of hati. This isn’t just about writing code; it’s about creating an app that people love and can’t live without. You will:

  • Lead product development: Build, ship, and iterate on the app, focusing on creating a seamless, delightful user experience.
  • Tinker and tweak: You’ll experiment constantly, optimizing every interaction to make the product feel intuitive and intentional.
  • Collaborate with the team: Work closely with the founder to translate user feedback into features that solve real problems.
  • Own the codebase: Architect, maintain, and refine a scalable, reliable foundation for the app.
  • Obsess over users: You’ll be deeply involved in understanding what users want and need—and you’ll care as much about the "why" as the "how."
What We’re Looking For

We’re not just looking for a coder—we want a builder, a creator, someone who’s obsessed with solving the dating problem. Our ideal candidate:

  • Is fluent in React Native: You can architect, build, and deploy robust, high-performance mobile apps for iOS and Android.
  • Sweats the small stuff: You believe the magic is in the details and love tinkering until every pixel and transition feels just right.
  • Is user-obsessed: You thrive on feedback and love building products that make people’s lives better.
  • Is relentless: You have a hacker mindset—you’ll push through challenges and figure things out no matter what.
  • Is mission-driven: You care deeply about fixing the loneliness epidemic and believe tech can foster real human connection.
Experience We Value
  • Expertise in React Native and a strong understanding of app development best practices.
  • Experience building consumer-facing mobile apps with a focus on UX/UI.
  • Comfort with API integrations and backend collaboration.
  • Startup experience or a passion for working in fast-paced, high-growth environments.
What’s In It for You?

This is more than a job—it’s a chance to build something from the ground up and change lives. As our Founding Engineer, you’ll:

  • Shape the future of hati and play a key role in redefining modern dating.
  • Work with an equity-based compensation package, with the potential for a full-time role as we scale.
  • Tackle one of the most challenging and rewarding technical problems out there—creating an app that feels effortless but delivers profound impact.
  • Be part of a small, passionate team that’s solving a problem that matters.
  • P.s. we have already built the app so you aren't starting from 0.
