Job description

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, * Codebase map: frontend, backend, database, integrations
Top 10 technical and product risks
What is broken versus merely messy
Estimate to stabilize HomeBase
Hiring plan for the next 30 to 60 days

Within 2 to 4 weeks:

Recovery roadmap
Technical debt triage
Recommended architecture changes
Test and QA priorities
One shipped stabilization improvement, or a verified implementation plan, Type: Contract (2 to 4 weeks, option to extend) Location: Remote, US Compensation: Candidate-proposed hourly or weekly rate Eligibility: Eligible to work in the US

Requirements

Do you have experience in TypeScript?, * 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
