We’re building Reflow, a workforce and workflow intelligence platform that helps teams understand and improve how work gets done. Our Mac app is at the center of it all: capturing rich data, delivering coaching, and powering insights. We’re looking for a senior Mac developer to take ownership of our macOS app, drive technical excellence, and help shape the foundation of our platform. What you’ll do • Lead macOS app development, architecture, performance, deployment, and long-term scalability. • Own the quality bar: profiling, debugging, optimizing for speed and stability. • Ensure compatibility across managed environments, including MDM and restricted setups. • Collaborate closely with backend and data teams to integrate APIs and improve system reliability. • Guide and mentor team members and other developers, helping elevate the overall engineering craft. • Build for the edge cases, from sandboxing and permissions to enterprise deployments. • Contribute to our CI/CD and testing practices, ensuring smooth builds and updates. Who you are • Expert in Swift and macOS app development, with a deep grasp of Apple frameworks, security, and system design. • Proven experience in profiling, debugging, and performance optimization across varied Mac environments. • Comfortable working in managed device contexts (MDM), understanding sandboxing, permissions, and deployment constraints. • Familiar with API integrations, backend collaboration, and maintaining reliable interfaces. • A stickler for detail, you notice inconsistencies others miss and care deeply about polish. • Experience with SwiftUI and Catalyst for cross-platform work is a strong plus. Bonus points • Knowledge of Django REST Framework or similar backend stacks. • Understanding of CI/CD pipelines and automated macOS testing. • Experience in security-focused or enterprise-managed environments. • Familiarity with enterprise compliance and privacy standards. Why join You’ll own a critical part of Reflow’s core product, the Mac app that powers everything else. You’ll work directly with the founders, influence the product roadmap, and shape the engineering culture. This is a role for builders who love technical depth and product impact. We’re open to full-time employment. High trust, high speed, and high impact. Compensation: We offer competitive pay based on the market and where you’re located. The salary ranges in our job postings are intentionally wide because they need to cover both U.S. and international candidates. Our final offer will depend on things like your experience, skill set, and location.
