About The Position
Base is seeking 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. The role requires someone who can quickly understand an existing codebase, identify architectural and execution risks, separate real problems from noise, and produce a practical recovery plan. The initial engagement is a 2 to 4 week paid audit, with the option to extend into implementation.
Requirements
- 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
- Eligible to work in the US
Nice To Haves
- 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
Responsibilities
- 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
Benefits
- Option to extend contract
