About Base
Base is a platform for in-real-life social connection and community. Our Members are accomplished people who have built careers, families, and reputations. They come to Base for what their calendars are missing: regular, in-person time with peers they actually want to know. The gathering is the product.
The systems that make it possible are what this role exists to protect.
Engagement
Contract: 2 to 4 week paid audit, with the option to extend into implementation.
About the Role
We are looking for a senior, hands-on engineer to audit and stabilize a consumer mobile product and its internal admin tool, HomeBase. The current system spans React Native, TypeScript, backend APIs, database-driven booking and payment workflows, notifications, and Metabase reporting. This is not a greenfield build. We need someone who can quickly understand an existing codebase, identify architectural and execution risks, separate real problems from noise, and produce a practical recovery plan.
What You'll Do
Audit the React Native and TypeScript mobile app and the related HomeBase admin flows
Review backend and API structure, database models, and the business logic around bookings, guests, cancellations, refunds, credits, and notifications
Identify technical debt, broken workflows, security risks, stale code, and missing tests
Review Linear and project artifacts, and compare planned work against actual implementation
Produce a prioritized technical recovery plan
Ship or supervise one small but meaningful stabilization fix during the engagement
Recommend the exact team needed to continue: mobile, backend, data, QA, design, or fractional CTO
Must Have
Senior or staff-level experience with React Native and TypeScript
Strong backend experience with APIs and relational databases
Experience with payments, refunds, booking systems, marketplaces, memberships, or operational and admin tooling
The ability to read messy code and make judgment calls quickly
Strong written communication: you can explain risks clearly to a non-technical founder or operator
Comfort working without perfect specs
Nice to Have
Experience with Metabase or analytics cleanup
Experience migrating away from NativeBase, NativeWind, or inconsistent styling systems
Experience with mobile release pipelines, QA automation, push notifications, and email workflows
Prior startup rescue, code audit, or fractional CTO experience

Within 5 business days:
