Job Description

We are creating the most ambitious iOS app to date.

This is a rare opportunity to join a rocket ship backed by world-class investors and already proven by tens of thousands of users who rely on Hero every day.

Company Background

Hero is the first AI Daily Assistant, a superapp to manage your day, coordinate with others, and soon, run every part of your life from messaging to payments, ordering food, booking, and beyond. We're creating a new category of an all-in-one AI-powered app, combining beautiful UI with deep intelligence.

  • TechCrunch
  • App store
  • Website

Hero has already replaced 8 apps for our users and this is just the start. With a fast-growing user base, glowing reviews, and clear product-market pull, we’re building something that could define how people interact with technology every day.

We're looking for a senior iOS engineer who wants to build fast, elegant, and reliable mobile experiences and help shape one of the most ambitious mobile products ever. You'll join a small, elite team and play a foundational role in crafting a next generation interface.

We have a world-class iOS team, with our CTO being the former iOS lead of Facebook Stories, and tech lead being a former iOS tech lead at both Amazon and Instacart.

We’re a seed-stage startup backed by top investors including Forerunner, Neo, Abstract Ventures, the Chainsmokers, Arash Ferdowsi (Dropbox founder and CTO), Ime Archibong (VP of FB Messenger), Max Mullen (co-founder Instacart), Scott Belsky (Chief Product Officer, Adobe) and more.

LOCATION:

SF Bay Area, in person (Burlingame) 5 days a week

  • Excellent problem-solving ability, from optimizing user experience to integrating backend data
  • Clear communicator capable of explaining technical concepts and trade-offs to non-technical team members

  • Hard-working – Expect to work hard on something that you will look back on and be incredibly proud of.
  • Low ego, good person – While we are ambitious, we highly value low-ego, good people. We believe you can be direct, efficient, and build great things, while being viewed by everyone as part of ‘their dream team’. We want to create an environment where everyone is good at what they do, and enjoys coming to work.

  • Work with a really talented team on something that will change millions of people’s lives.
  • Significant equity, good salary, and medical and dental.
  • Whatever else you are interested in, we can figure out – We are committed to hiring the best and setting you up to love what you do every day.
