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 flexible on structure, part or full time, as long as you can move fast and deliver with quality.
