## About the Role

We are looking for a Senior iOS Engineer to own Sekai’s iOS app and help us build a fast, polished, AI-native consumer experience. This role is for someone with strong iOS experience, good consumer product taste, and the ability to move quickly in a startup environment. You should keep up with the latest Apple platform updates, understand what great mobile apps feel like, and be excited to use AI to rethink how fast a small team can build. You will work closely with Product, Design, Backend, and Mobile engineers to improve the iOS app experience, ship new features, and help define our AI-native mobile development workflow.

## Responsibilities

- Own and improve Sekai’s iOS app experience, quality, and release velocity
- Build and ship consumer-facing iOS features with strong attention to speed, polish, and reliability
- Bring modern iOS best practices and the latest Apple platform knowledge to the team
- Work across native iOS, hybrid mobile, and web-based app experiences when needed
- Partner closely with Product, Design, Backend, and Mobile engineers to move from idea to shipped product quickly
- Use AI development tools to accelerate coding, debugging, refactoring, and product iteration

## Qualifications

- Strong professional experience building and shipping iOS apps
- Deep familiarity with Swift, iOS SDK, and modern iOS development practices
- Experience working on consumer mobile apps with high standards for UX, performance, and reliability
- Experience owning projects end-to-end in a startup, 0-to-1 product environment, or similarly fast-moving team
- AI-native mindset: you actively use AI tools to build faster, explore better implementation paths, and improve engineering productivity
- Strong product sense and willingness to work closely with design and product teams

## Nice to Have

- Experience with social, entertainment, creator, gaming, UGC, or feed-based consumer products
- Experience with React Native, Flutter, WebView, or other hybrid mobile architecture
- Familiarity with Android, backend systems, or full-stack product development
- Experience working on AI-native products or teams that heavily use AI in day-to-day development

## What We Offer

- Top compensation package, including competitive salary and meaningful equity
- Comprehensive health insurance and benefits

If you are excited about building at the frontier of AI, consumer social, and interactive entertainment, we would love to hear from you. At Sekai, you will work with an AI-native team, move fast, own meaningful problems, and have the flexibility to explore new ideas from an early stage.

## About Sekai

## Company Overview
- **One-liner**: Sekai is an AI-native social platform that lets anyone create, play, and remix interactive mini-apps (called "Sekais") using text prompts, turning software into shareable cultural artifacts.
- **Entity Type**: Private (Series A; raised $20M in June 2026)
- **Headquarters**: Sunnyvale, California, United States
- **Founded**: 2023 (incorporated as Versa AI, Inc.)
- **Founders**: Lucky Zhang

## Core Business
- **Primary industry/industries**: AI-powered social content / User-generated mini-apps / Generative interactivity
- **Target customers**: B2C – consumers (especially younger demographics) who want to create, discover, and remix playful, utility, or fan-interaction mini-apps; also creators and potential celebrity partners.
- **Mission or purpose statement**: To move beyond static content (text, image, video) and build the first ecosystem for "Generative Interactivity" – making software a medium for creative expression and social sharing.

## Products & Services
- **[Sekai Platform (app + web)]**: An AI-driven platform (iOS, Android, and web) where users describe an idea in natural language and a mini-app is instantly generated. Apps can be utilities, quizzes, polls, cards, games, or fan experiences. Users can play, remix others' creations, and share them. Includes a creator monetization path (in development). **Type**: AI-powered SaaS / mobile app

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed (private company).
- **Key Metric**: Total funding – $26M ($20M Series A co-led by Khosla Ventures and Connect Ventures in June 2026, plus $6M seed led by Mayfield in 2025). Also received $3M in pre-seed/non-equity assistance in 2024.
- **Notable Investors/Partners**: Khosla Ventures, Connect Ventures (joint CAA/NEA), a16z Speedrun, Mayfield, A*, MVP Ventures, 359 Capital, Parable VC, 645 Ventures. Early backing from a16z Games Speedrun.
- **Growth Signals**: 
  - 15 million mini-apps created, with over 200,000 generated daily.
  - Users spend more than 1 hour per day on the app.
  - 550% YoY headcount growth (from ~3 to 16 employees).
  - 4,689 LinkedIn followers (+611.5% yearly).
  - Active hiring: 7 open positions as of July 2026.

## Competitive Advantages
- **First-mover in AI-native social app creation**: Unlike traditional social media, Sekai enables true interactive creation – not just content consumption.
- **Remix culture + low barrier**: Users can create without coding; remixing others' apps lowers friction and drives viral loops.
- **Strong engagement metrics**: >1 hour daily usage signals product-market fit and user “obsession” (per investor Nicole Quinn).
- **Founder track record**: Lucky Zhang previously sold startups to Apple (Yi+ AI) and ByteDance (Blacktail), showing execution and exit experience.

## Strategic Focus
- **Scaling the creator economy**: Sekai plans to help creators earn money from their mini-apps and interactive fan experiences.
- **Expanding partnerships**: Working with CAA on creator and celebrity partnerships.
- **Hiring aggressively** for engineering, product, and AI roles to build out the platform and mobile experience.
- **Broadening beyond anime/fan-fiction** (initial niche) into general-purpose mini-app creation as AI coding models improve.

## Why Work Here
- **Culture of creativity and impact**: Sekai describes itself as the “first AI-native social platform” – employees get to build a new medium, moving beyond doomscrolling to active creation and interaction.
- **Early-stage growth**: Very small team (16 people) with massive funding ($26M) and explosive user traction – high ownership and ability to shape product.
- **Founder with serial success**: Working under Lucky Zhang, who has sold two companies to Apple and ByteDance, provides credible leadership and deep AI/social experience.
- **Remote/hybrid policy**: Likely flexible; job postings on Ashby (e.g., AI Product Engineer) include "Remote" tag. HQ is in Sunnyvale, CA, but team spans US, Indonesia, Singapore, NZ.
- **Notable perks/engineering culture**: Focus on rapid prototyping, AI tools, and user-generated content. Roles posted include "AI Agent Engineer," "Senior Data Engineer," "AI Product Engineer" – strong AI engineering environment.
