We help retailers fill shifts faster while giving workers more flexibility and better opportunities. Operating across 25+ states and supporting thousands of W2 associates, we’re creating the infrastructure layer that powers the future of hourly work. We’re a fast-moving, mission-driven team tackling complex problems across marketplace dynamics, scheduling, compliance, payments, and workforce operations. Our ambition is simple: build the category-defining platform for flexible labor. ## The Role We're looking for a Senior Software Engineer to become the primary owner of our mobile application, the core experience used by thousands of workers every day. You'll inherit a mature, production React Native codebase and take responsibility for its architecture, quality, and direction. This is a high-ownership role. You won't be the only person touching mobile, but you'll be the one setting the standard: defining best practices and raising the bar in code review. You'll work across the stack where it helps you ship, partnering closely with product, design, and backend. If you like owning a product end-to-end, care about craft, and want your fingerprints on how a team builds (not just what it ships), this is for you. ## What You’ll Do - Own the architecture, quality, and direction of our React Native apps. - Hold the technical bar for mobile through code review, standards, and mentoring. - Run the release process end-to-end, including App Store and Play Store listings. - Turn ambiguous product problems into intuitive, high-quality experiences alongside product and design. - Ship features from architecture through deployment and iteration. - Drive improvements in performance, reliability, observability, and developer experience. - Contribute across the stack, including React web and backend services. We’re Looking For - 5+ years building and shipping production software. - Deep React Native expertise, including apps you've taken to scale in production. - Strong command of React and TypeScript. - A track record of raising the bar on a team: setting standards, reviewing code, mentoring engineers. - Comfort working across the full stack and designing/consuming APIs. - Strong product instincts and a bias toward shipping. - A clear communicator who collaborates well and thrives in startup ambiguity. Bonus Points - Experience with marketplace, logistics, scheduling, or consumer products. - Experience with mobile performance optimization and observability. - Familiarity with Django, GraphQL, PostgreSQL, or AWS. - Startup experience and a track record of owning products from zero to one. Why Reflex? - Real ownership: you'll own the mobile surface outright, not a slice of it. - Early-stage upside: meaningful equity and a seat at the table as we scale. - A team worth joining: high-ownership, low-ego, and serious about craft If you’re excited about building products that have real-world impact and want to help create the infrastructure powering the future of labor, we’d love to talk. Our customers and users come from all walks of life, and so do we. We hire great people from a wide variety of backgrounds. If you share our values and our enthusiasm to improve retail, you'll find a home here at Reflex. Reflex is proud to value diversity at our company. All qualified applicants will receive consideration for employment. ## About Reflex ## Company Overview - **One-liner**: Reflex provides an open-source, full-stack Python framework and cloud platform for building and deploying mission-critical enterprise applications entirely in Python. - **Entity Type**: Private (Startup – Y Combinator Winter 2023 batch, recent undisclosed funding round) - **Headquarters**: San Francisco, California, USA - **Founded**: 2023 - **Founders**: Alek Petuskey, Nikhil Rao ## Core Business - **Primary industry**: Developer tools / Infrastructure / Artificial Intelligence - **Target customers**: Enterprise teams (30% of Fortune 500), internal tool builders, data scientists, analysts, and Python developers; B2B with a strong open-source community (B2D). - **Mission/purpose statement**: “Reflex unifies the fragmented enterprise app stack — frontend, backend, data, and deployment — into one Python-native platform.” ## Products & Services - **Reflex Framework** (Open‑source, Apache 2.0): A Python library (`pip install reflex`) that lets developers build interactive web apps using pure Python – frontend, state, backend logic, and data models. Includes 60+ built‑in React components, reactive state management, routing, auth, database management, and API endpoints. - **AI Builder**: A web tool (build.reflex.dev) that generates complete Reflex applications from natural language prompts. - **Reflex Cloud**: One‑command hosting platform (`reflex deploy`) with SSL, CDN, auto‑scaling, multi‑region support. - **Reflex Enterprise**: On‑premises / VPC deployment with SSO, audit logs, and dedicated support. ## Market Standing - **Valuation**: Not publicly disclosed (conflicting reports may be absent; YC profile states “just raised another round of funding” but amount not given). - **Key Metric** (Private startup): Total funding not specified (YC-backed; additional round raised recently). Community metrics: 28,000+ GitHub stars (as of YC update), 1,000,000+ apps built, used inside 30% of Fortune 500 companies. - **Notable Investors/Partners**: Y Combinator (Winter 2023 batch); primary partner Jared Friedman. - **Growth Signals**: Rapid community growth; used by Fortune 500 companies for internal tools; expanding AI‑builder capabilities; MCP integration for agentic coding; team size of 10 (as of YC listing) and actively hiring. ## Competitive Advantages - **Unified Python stack**: Replaces the need to stitch together React, FastAPI, Airflow, auth, and deployment – all in one Python codebase. - **AI‑native**: Purpose‑built for AI agents (MCP integration); every Reflex app automatically exposes an MCP, enabling agents to interact via API without browser automation. - **Open‑source with production ceiling**: Apache 2.0 license, but the platform scales to critical enterprise use cases (on‑prem, VPC, SSO, audit logs). - **Developer experience**: No page reloads, no callback nesting; reactive state management that compiles to a React frontend while staying pure Python. ## Strategic Focus - Replacing the fragmented enterprise application stack with a unified platform. - Deepening AI capabilities (agentic coding, MCP) to serve both human developers and AI agents. - Expanding enterprise adoption (Reflex Cloud, Enterprise, and on‑prem deployments). - Growing the open‑source community and ecosystem (wrapping any React library, integrating with existing Python libraries). ## Why Work Here - **Culture**: “Work with people who are genuinely passionate about improving the web.” Founding team includes open‑source maintainers, top‑ranked competitive programmers/IOI medalists, and former founding team members from dev tool unicorns. - **Growth trajectory**: Extremely fast community growth (1M+ apps built, 28K GitHub stars) and a recently closed funding round – early stage with significant upside. - **Location & policy**: San Francisco (office/hybrid expected). Equity grants are offered (e.g., 0.05%–0.50% range for engineering roles). - **Notable perks**: High degree of ownership; work on the open‑source framework, cloud infrastructure, and AI tooling; direct impact on product direction. ## Sources 1.
