Senior Software Engineer (Mobile) - App Factory

At Kikoff, we are redefining how people build financial confidence - helping millions of Americans establish credit, access smarter products, and reach their financial goals.

We are launching a new initiative: a small, high-leverage incubation team focused on exploring and validating new product verticals that will shape the future of Kikoff. Operating like a startup within the company - fast-moving, experimental, and deeply aligned with Kikoff’s broader mission, this team blends deep platform engineering with 0 to 1 product execution. The team is responsible for Kikoff’s app factory, the foundations that enable rapid app creation and experimentation, while simultaneously using it to build, test, and refine new product ideas that will define Kikoff’s next chapter.

We are looking for a Senior Software Engineer who is excited to build from zero, driving both product and platform outcomes. You’ll:

• Architect and ship the first version of a new 0 to 1 product - from concept to launch.

• Design and own reusable systems, growth tooling, and experimentation infrastructure that accelerate iteration across this and future Kikoff verticals.

• Balance speed with foundation - knowing when to move fast to learn, and when to invest in the right abstractions to scale.

This is a rare opportunity to incubate new businesses within a fast-growing fintech, while building the technical backbone that will power Kikoff’s next generation of products. If you thrive on blank-canvas building, love solving ambiguous problems, and care equally about building things right and getting things into users’ hands fast, you’ll fit right in.

What you’ll be doing

• Build and launch new 0 to 1 user experiences end-to-end in Flutter, from rapid prototypes to production-quality apps.

• Design elegant, performant mobile UIs that express Kikoff’s brand and make financial progress intuitive for our members.

• Develop reusable mobile modules, design systems, and feature scaffolds to accelerate experimentation and iteration speed.

• Partner with backend engineers to define APIs, data contracts, and experimentation hooks that enable rapid learning.

• Instrument user flows with analytics and A/B testing frameworks to measure impact and guide iteration.

• Help shape Kikoff’s mobile platform foundations - improving build systems, CI/CD pipelines, and developer velocity.

What we’re looking for

• 4+ years of mobile development experience (preferrably with Flutter in production).

• Deep understanding of Flutter architecture, state management, and performance optimization.

• Experience working across the stack (API design, data modeling, analytics).

• Excited by fast iteration, ownership, and helping shape platform foundations for future products.

• Strong product sense - you care about the “why” behind features as much as the “how.”

• Entrepreneurial mindset - thrives in ambiguity, takes initiative, and loves turning ideas into working systems.
