Software Engineer

SENIOR SOFTWARE ENGINEER — REACT NATIVE & FULL-STACK Remote | Contract-to-Hire | $100–$140/hour USD ABOUT LEDBY Great fitness and wellness experiences start with great people. The instructor who inspires you. The coach who pushes you further. The teacher who makes you look forward to showing up. Those relationships can make all the difference. Yet the fitness and wellness industry is still largely organized around places, schedules, and disconnected platforms rather than the people who make these experiences meaningful. We're building LedBy to change that. LedBy is an instructor-first fitness and wellness platform connecting people with inspiring instructors, coaches, studios, and experiences—from yoga and Pilates to strength training, CrossFit, private sessions, and wellness retreats. For consumers, we're making it easier to discover great instructors, find experiences, and stay connected with the people who inspire them. For fitness and wellness professionals, we're creating tools to grow their visibility, strengthen client relationships, manage their offerings, and build more sustainable businesses. Our public Web beta is live, and we're actively developing our broader web and native mobile platform. In 2 weeks, we hit +1,200 unique visitors on our beta launch with dozens of instructor sign-ups and 3 studios signing up. That was all organic growth simply by letting just 2 instructors use LedBy for themselves as yoga instructors. We're a small, ambitious team building toward a much bigger vision, and we're looking for an exceptional engineer to help us get there. THE OPPORTUNITY We're seeking an experienced, product-minded Software Engineer for a remote contract engagement, with the potential to transition into a full-time position as LedBy grows. This isn't a role focused on routine feature tickets or simply producing more code. We're looking for someone who enjoys solving challenging technical problems, identifying root causes, improving architecture, and making complex systems work reliably. You'll collaborate directly with the founding team, take ownership of clearly defined technical projects, and help shape the quality, performance, and future of our platform. We already use modern AI-assisted development tools. We're looking for an engineer who brings the deeper technical expertise, judgment, and hands-on debugging capabilities needed to make that work production-ready. EXAMPLES OF PROJECTS YOU COULD WORK ON Your projects will be selected based on our highest-priority engineering needs and your particular expertise. React Native & Mobile Engineering: Diagnose and resolve challenging iOS and Android issues involving React Native, Expo, native rendering, typography, layout, application lifecycle, and cross-platform compatibility. Identify underlying causes and validate reliable solutions on actual applications and devices. Backend Architecture & Security: Strengthen PostgreSQL/Supabase architecture, APIs, authentication, authorization, and data integrity. Investigate difficult security, account-isolation, permission, and session-recovery issues. Marketplace & Booking Reliability: Improve scheduling, reservations, cancellations, attendance, and other transactional workflows. Solve concurrency issues, duplicate operations, network interruptions, and inconsistent states to ensure users can depend on the platform. Infrastructure & Production Reliability: Improve deployment processes, automated testing, monitoring, performance, and recovery. Help establish safe database migrations, release verification, and reliable rollback strategies. Third-Party Integrations: Develop and validate secure integrations involving payments, communications, scheduling systems, and external APIs. Handle webhooks, idempotency, reconciliation, and failure recovery. Product Quality & Cross-Platform Experience: Help turn approved designs into polished consumer experiences. Resolve difficult accessibility, responsive design, performance, and usability problems across web and mobile. We don't expect one person to handle everything immediately. We'll prioritize specific, high-impact deliverables together. WHAT WE'RE LOOKING FOR 5+ years of professional software engineering experience, or equivalent demonstrated technical expertise. Strong proficiency in TypeScript, JavaScript, React, and modern full-stack development. Hands-on experience with React Native and Expo, including debugging real iOS and Android applications. Experience with backend APIs, SQL, PostgreSQL, authentication, and secure data access. Strong understanding of application architecture, automated testing, debugging, security, and performance. Experience diagnosing and resolving complex problems in production applications. Ability to independently investigate issues, explain technical tradeoffs, and deliver well-tested solutions. Strong communication skills and comfort collaborating remotely with a small founding team. Especially valuable experience includes native iOS/Android development, React Native's New Architecture and Fabric, Supabase, Cloudflare Workers, CI/CD, and consumer marketplace applications. You don't need experience with every technology listed. We value strong engineering fundamentals, demonstrated problem-solving ability, and the capacity to learn quickly. WHAT SUCCESS LOOKS LIKE We care about meaningful product improvements—not hours logged, lines of code written, or the number of features shipped. Success might mean permanently resolving a difficult mobile issue, making a critical customer workflow reliable, eliminating a security vulnerability, or establishing a safer and more repeatable release process. We're looking for someone who can take a challenging problem, investigate its underlying cause, deliver a thoughtful solution, and demonstrate that it works. WHY JOIN LEDBY? Meaningful impact — Build technology that supports real human connections, healthier lifestyles, and the professionals who make those experiences possible. Early-stage influence — Help shape the architecture, quality, and direction of an evolving consumer technology company. Interesting engineering challenges — Work on complex mobile, backend, marketplace, security, and reliability problems. Direct founder collaboration — Work closely with a team that cares deeply about product quality, design, and customer experience. Opportunity to grow — Begin with a paid contract and potentially expand into a full-time role as the company grows. We're looking for someone who wants to build something meaningful and take pride in doing it exceptionally well. CONTRACT DETAILS Location: Remote, with some overlap with U.S. Pacific Time preferred. Engagement: Paid contract, beginning with clearly defined projects and deliverables. Compensation: $100–$140 USD per hour, depending on experience and specialization. Commitment: Flexible, with project scope and hours agreed upon in advance. Future opportunity: Potential transition to a full-time position based on mutual fit, performance, and company needs. HOW TO APPLY We'd love to learn about what you've built and how you approach difficult technical challenges. Please share Your resume or LinkedIn profile. Links to relevant applications, GitHub repositories, or projects you've contributed to, where available. A brief example of a challenging technical issue you've solved, including how you diagnosed the root cause and verified your solution. Your experience with React Native, full-stack development, or production engineering. Your availability and preferred hourly rate. We care more about demonstrated ability, thoughtful problem-solving, and ownership than credentials alone. If you're excited about solving meaningful technical challenges while helping build an ambitious fitness and wellness technology company, we'd love to hear from you.
