Senior Full-Stack Engineer, Growth & Community Platform

Acorns; United States; Remote; USD 175,000 - 206,000; Full time

Job summary

Acorns is building a new Community product team. As a Senior Full-Stack Engineer, you will own features end-to-end across iOS, Android, Web and backend services to power Acorns' organic growth through social graphs, referrals, sharing flows, and real-time interactions.

You will work directly with the CEO, a Senior PM and a Senior Designer, shaping architecture, instrumentation, and analytics, using AI-assisted tools to accelerate delivery and ensure scalable, high-quality product experiences

Qualifications

• Built social or engagement systems at scale with feeds, referral flows, notification infrastructure, social graphs, or real-time interactions at a gaming or consumer social company
• Owned a feature end-to-end across the full stack: you designed the data model, wrote the API, shipped the client, and monitored it in production
• Shipped production features across more than one client platform (iOS, Android, or Web) - you have depth in at least one and have demonstrated you can build in the others with ramp-up time and modern tooling
• Instrumented a growth or engagement feature with analytics events and used the data to drive meaningful iteration
• Worked in a fast-moving, low-process environment where you drove your own work without waiting to be told what to build next
• Used AI-assisted development tools (Claude, Copilot, or similar code-generation tools) as genuine accelerators - you see them as force multipliers, and have a clear point of view on how to use them well
• Written production code in Swift, Kotlin, React Native, Typescript, Dart, or Python that served millions of users
• Built something - a side project, an open source tool, a game mechanic - because you wanted to, not because someone asked you to

Responsibilities

• Build the mechanics that make a product spread including referral systems, social sharing flows, engagement loops, and real-time features that drive Acorns' organic growth
• Own features end-to-end from data model to shipped customer experience, across mobile and web, with full accountability for quality and performance in production
• Deliver features end-to-end across iOS, Android, Web, and backend services, moving fluidly between platforms depending on what each initiative requires, and leveraging AI-assisted development tools to accelerate work in less-familiar codebases
• Instrument your work properly: define the events, build the visibility, and use data to iterate fast
• Take full ownership of the technical bar and architecture, while upholding engineering standards, where your decisions have outsized impact and every voice counts
• Partner directly with the CEO, a Senior PM, and a Senior Designer in a tight, high-trust team that moves fast and ships things people actually use
