Senior Product Engineer, React Native + Backend (Contract)

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

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
