Compensation: $170,000 – $220,000 base + 0.5% – 1.5% equity
Hiring: 1–2 Founding Engineers

Overview

Our Client is a venture-backed startup building a new consumer primitive: an accountability protocol that adds real financial stakes to personal goals.

The company is the first to successfully navigate the regulatory and infrastructure barriers that previously prevented this market from existing. The business is well-capitalized, resourced for multiple years, and protected by a meaningful regulatory moat.

Hiring two Founding iOS Engineers is the company’s #1 priority . The interview process is highly efficient and moves from initial screen to offer in 7–14 days .

  • Own large portions of the product with real autonomy

  • Influence product direction, UI/UX, and overall polish

  • Wear multiple hats in a true founding-team environment

Tech Stack

  • Swift (primary)

  • Native iOS development

  • Backend/API collaboration

  • On-chain interaction support

Experience Requirements

  • 2–8 years of software engineering experience

  • Strong product intuition and attention to detail

  • Ability to contribute to backend/API design

  • High bar for design, UX, and performance

Soft Skills & Mindset

  • Comfortable with ownership, ambiguity, and speed

  • Strong collaboration and communication skills

  • Demonstrated history of building outside of work or school (projects, apps, Web3, music, art, etc.)

Traits We’re Avoiding

  • Engineers who have only worked on poorly designed or low-quality iOS apps

  • Candidates looking for “just another job” instead of a founding opportunity

Interview Process

Efficient and founder-led:

  1. Initial Screen (30 minutes)

    • Assess mindset, interest, and alignment

  2. Technical & Product Conversation (30 minutes)

    • Deep dive into technical background and product thinking

  3. Technical Problem-Solving Interview (60 minutes)

Why This Role

  • Consumer product with regulatory protection

  • Strong runway and serious backing

  • Opportunity to build something that hasn’t existed before
