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: 4 to 6 week paid audit, with the option to extend into implementation. ## About the Role We're looking for a senior, hands-on engineer to audit and stabilize a consumer mobile product and its internal admin tool, HomeBase. This is a 4-week paid trial: come in, understand the system fast, separate the real problems from the noise, and ship. It's a stabilization engagement, not a net-new feature role. The long-term build-and-own seat is a separate Tech Lead position. The system spans a React Native + Expo mobile app, a TypeScript monorepo, two backend APIs on AWS (a member-facing API and an admin/back-office API) that run the Stripe payment, subscription, and refund integrations, a Supabase Postgres database with hundreds of migrations, an automation and data-integration layer (n8n-style workflows plus reverse-ETL into downstream tools), and Metabase reporting. Parts of it are mid-migration and lightly tested. 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 ship fixes that hold. ## What You'll Do - Audit the React Native + Expo mobile app and the HomeBase admin flows. - Review the backend and API structure, the Postgres data models, and the business logic around bookings, guests, cancellations, refunds, credits, and notifications. - Trace the payment path (Stripe) and the automation / data-integration layer (n8n-style workflows and reverse-ETL) for fragility and silent-failure points. - Identify technical debt, broken workflows, security gaps, stale code, and missing tests. - Review Linear and project artifacts, and compare planned work against what actually shipped. - Produce a prioritized technical recovery plan. - Ship or supervise one small but meaningful stabilization fix during the trial. - Recommend the exact team needed to continue: mobile, backend, data, QA, or design. Must Have - Senior or staff-level full-stack experience shipping production React Native + TypeScript apps. - Strong backend experience building and operating GraphQL APIs on a relational database (Postgres or similar), deployed on a cloud provider. We run AWS + Supabase. - Hands-on Stripe across subscriptions, refunds, invoices, webhooks, and reconciliation, integrated into backend services (ours run on AWS). - You've worked inside messy, partially-migrated, lightly-tested systems and brought order without freezing delivery. - You make fast, pragmatic judgment calls in unfamiliar code and explain them clearly to a non-technical founder. - 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 - Expo and EAS builds in production, with manual store submission (no OTA). - Apollo Client and GraphQL on the front end. - Supabase specifically (Auth, Postgres, Storage). - Automation glue and reverse-ETL: n8n, Hightouch, Airflow, or similar. - Stripe in a booking, marketplace, or membership context. - Mobile observability and E2E testing: Sentry, PostHog, Maestro. - Metabase or analytics cleanup. - Migrating away from NativeBase, NativeWind, or inconsistent styling systems. - Untangling a codebase mid-rewrite (legacy and new trees coexisting in production). - Prior startup rescue or code-audit experience. First Deliverables Within 5 business days: - 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 4 to 6 weeks: - Recovery roadmap - Technical debt triage - Recommended architecture changes - Test and QA priorities - One shipped stabilization improvement, or a verified implementation plan Details Type: Contract (4 to 6 weeks, option to extend) Location: Remote, US Compensation: Candidate-proposed hourly or weekly rate Eligibility: Eligible to work in the US How to Apply Apply through the link below. You'll be asked to share work samples, relevant experience, your availability, and to answer one short screening question: Describe a production system you inherited that had a single point of failure: a sole owner, a fragile integration, no monitoring, or no tests. What did you stabilize first, and why that one? Alongside your answer, upload a visual representation of that work: a system map, architecture diagram, data-flow sketch, or whiteboard photo of the system you describe. It can be rough. We want to see how you picture a system, not only how you write about it. Base is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status. ## About Base ## Company Overview - **One-liner**: Base is a tech-powered social club that curates in-person gatherings and experiences to foster authentic, meaningful connections among a vetted, growth-minded professional class in major cities. - **Entity Type**: Private (Startup) - **Headquarters**: Miami, Florida, USA - **Founded**: 2022 - **Founders**: Kaben Clauson (Co-Founder & CEO), Ricardo Vázquez (Co-Founder & CTO), Natalia Martinez-Kalinina (Co-Founder) ## Core Business - **Primary industry/industries**: Technology / Social Networking / Hospitality / Events - **Target customers**: B2C (individual professionals seeking community, new friendships, and curated social experiences in their city) - **Mission or purpose statement**: To help people connect with authenticity in cities around the world, combining the power of technology with world-class hospitality to unlock new learnings, connections, and friendships for members. The company describes its mission as "making magic for people where it matters most." ## Products & Services - **Membership**: A paid, vetted social club membership granting access to curated in-person events. Members are personally interviewed, and acceptance is limited to keep communities intentional. The core product offering includes several types of gatherings: - **Circles**: Small, curated dinner parties with conversation prompts designed for deep, substantive dialogue. - **Experiences**: Gatherings built around discovery (e.g., tastings, workshops, studio tours, hikes). - **Socials**: Larger community events ("the room where members you've met at smaller gatherings become friends"). - **Membership App**: A digital platform (likely mobile-first) for members to discover events, connect with the community, and manage their membership. - **Base+**: A perks program for members, including luxury gym discounts and airport lounge access. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed. - **Key Metric**: Total Funding (not publicly available); Revenue (not publicly available); Headcount: 41 employees (+21.6% YoY), with 16 active job postings at the time of research. - **Notable Investors/Partners**: Investors are not publicly listed. Alumni talent have reportedly come from companies like United Airlines, Slalom, and Fever. - **Growth Signals**: Expanding into new cities (e.g., Austin, Chicago); strong headcount growth (+21.6% YoY); significant increase in job postings (+220% quarterly); growing social media presence (4,617 LinkedIn followers, +57.2% yearly). The company describes itself as "growing FAST." ## Competitive Advantages - **Curated, High-Bar Membership**: Base limits membership to a small number of new applicants per month per city, and personally interviews every candidate. This creates a high-intent, high-quality community that is hard to replicate. - **Tech-Powered Matching**: An algorithm is used to match members to experiences and other members, designed to foster stronger, more intentional connections than a typical social club or networking event. - **"Product is the Room" Philosophy**: Base operates without a single clubhouse, using unique, rotating venues across each city. This approach keeps the experience fresh and dynamic, and avoids the fixed overhead of a physical location. - **Anti-Networking Culture**: Explicitly defines itself against "small talk" and "pitching." The brand is built on genuine connection, substance, and authentic conversation, differentiating it from many professional networking platforms. ## Strategic Focus - **Geographic Expansion**: Currently headquartered in Miami, Base is actively expanding to new US cities, including Austin and Chicago, where it is hiring General Managers (GMs). - **Product & Engineering**: The company is a "technology company at its core." It is actively hiring for a Senior Product Engineer (React Native + Backend) to "audit and stabilize HomeBase across React Native, backend APIs, booking, payments, reporting, and recovery planning," suggesting a focus on product maturity and infrastructure. - **Community Curation & Member Experience**: Investment in roles like "Head of Member Success" and "Membership Interviewer" indicates a strong focus on the quality of the member experience and community curation. ## Why Work Here - **Culture & Mission**: The company emphasizes a mission-driven culture focused on "magic," authentic connection, and intellectual curiosity. Internal values include "Show Up Fully," "Growth Mindset," "People Over Pitches," and "Share the Stage." - **Remote & Location**: Base operates with a remote-first culture for many roles (e.g., Engineering, Social Media), but also has roles requiring in-person presence (e.g., City Host, GM). The company has physical office space in Miami ("OnSite Workspace" is noted, but typical time on-site for office roles is listed as "None"). - **Perks & Benefits**: Based on job postings, Base offers company equity, an employee stock purchase plan, performance bonuses, and clear promotion policies with customized development tracks. It also provides diversity-based Employee Resource Groups (ERGs), childcare benefits, generous parental leave, and comprehensive health insurance. - **Engineering Culture**: The engineering team is described as "product team... growing." The Senior Product Engineer role is a contract position that touches the entire product surface area (mobile, backend, payments, reporting), suggesting a hands-on, high-impact environment. - **Headcount & Stage**: With 41 employees and a strong growth rate, this is an early-stage startup environment where employees can wear multiple hats and have significant impact. ## Sources 1.
