We’re looking for a Senior iOS Engineer to join Monstro as our foundational iOS hire. This is a unique opportunity to own and architect the entire iOS experience for a next-generation consumer fintech platform — from first line of Swift to shaping how millions engage with their finances.
You’ll work closely with design, product, and executive leadership to bring prototypes to life, establish our mobile architecture, and define how iOS development is done at Monstro. You’ll be hands-on from day one — helping us build, ship, and scale our mobile product while laying the foundation for a future iOS team.
The ideal candidate is a senior iOS expert who thrives in ambiguity, moves fast, and obsesses over user experience. You have a startup mindset and are excited to build from the ground up — from picking between UIKit vs. SwiftUI to setting the tone for iOS engineering excellence at Monstro.
Monstro, headquartered in New York, is an innovative AI-enhanced fintech company redefining personal finance management through a global financial platform. Our platform offers individuals a comprehensive view of their entire financial, legal, and tax life, delivering actionable insights, tailored recommendations, and the ability to take direct action.
For financial institutions, Monstro unlocks unparalleled access to personalized customer data and insights. Leveraging Monstro’s data-driven approach allows institutions to maximize revenue, boost customer retention, and attract new clients while lowering acquisition costs. By efficiently servicing clients across all wealth tiers and providing direct, actionable solutions, Monstro is transforming the financial services landscape.
We are democratizing access to high-quality financial advice, enabling institutions to optimize operations, empower their clients, and achieve measurable growth in an evolving digital economy.
