Senior iOS Engineer, Money Forward Cloud, Fukuoka

About Us

At Money Forward, we are dedicated to transforming financial services using advanced technology. With over 50 services for individuals and businesses, including popular products like Money Forward ME and Money Forward Cloud, we help make managing money easier. We use “account aggregation” technology to gather user data, turning it into useful insights for our customers.

Our company has reached a turning point from "Cloud to AI" and is accelerating company-wide AI Transformation (AX) toward achieving our goal of becoming the "No. 1 Back-Office AI Company in Japan" under "Money Forward AI Vision 2026."

Leveraging our robust customer base of over 440,000 companies and years of accumulated business logic, we are expanding beyond the traditional SaaS market into the ¥14.1 trillion "Digital Worker" market, where autonomous AI agents substitute and augment human labor.

To turn this grand ambition into reality, we are driving "AI-PDLC / AI-SDLC (AI-Driven Development)" to redefine the product development process itself. We are seeking engineers who want to look beyond simple SaaS feature additions—redefining architecture and user experiences using cutting-edge AI agent technologies to co-create next-generation products across job functions.

Overview

At Money Forward, we leverage technology to solve financial challenges for businesses and individuals. Our Fukuoka office leads the development and operations of our flagship B2B services: Money Forward Expense and Money Forward Payables.

We are looking for an iOS Engineer to join the Money Forward Expense team. Money Forward Expense is an enterprise SaaS platform that integrates data across diverse back-office platforms and applications to automate and streamline expense management workflows.

Our mobile development team is dedicated to shipping new features and continuously refining UI/UX so users can effortlessly manage expenses from their smartphones. Enhancing app stability, resilience, and overall product quality is equally central to our mission.

We welcome applications from iOS engineers who are excited to collaborate across disciplines, tackle complex technical challenges, and drive the continuous growth of our product.

Since opening in December 2017, Money Forward’s Fukuoka Development Base has steadily expanded alongside a growing community of talented engineers and designers.

In November 2025, we relocated our office to "Fukuoka Daimyo Garden City" to set the stage for our next chapter of growth. We are now aggressively recruiting engineers and designers to help our organization leap forward.

Our local vision is "Move Forward." We place the highest priority on growth opportunities for every member, striving to be an energetic hub where everyone can boldly take on new technologies and complex challenges.
