You'll have significant ownership over the technical direction and execution of these systems while helping scale the engineering team.

Responsibilities

• Lead, mentor, and develop a small team of backend engineers, with responsibility for technical execution, performance management, and career development.
• Own the architecture, development, and reliability of backend systems supporting payments, subscriptions, and member lifecycle workflows.
• Remain technically hands-on, contributing approximately 20% of your time to coding, alongside code reviews, system design, and architectural decisions.
• Design and maintain integrations with Apple StoreKit 2, App Store Server APIs, and server-side subscription billing infrastructure.
• Build robust workflows for transaction verification, subscription renewals, server notifications, payment reconciliation, and entitlement management.
• Establish best practices around testing, observability, incident response, deployment, and production reliability.
• Partner with product and cross-functional teams to define priorities, manage technical tradeoffs, and deliver new capabilities.
• Hire and develop engineers as the team grows, maintaining a high bar for technical excellence and ownership.
• Incorporate AI development tools into engineering workflows while ensuring sound technical judgment, maintainability, and reliability.

Required Skills

• 3+ years of engineering management experience, including managing, mentoring, and developing software engineers.
• Strong production experience with Apple StoreKit 2, including subscription and in-app purchase integrations.
• Deep understanding of server-side payment and subscription infrastructure, including Apple server notifications, App Store Server APIs, transaction and receipt verification, webhook handling, and reconciliation.
• Strong backend engineering background with experience designing and operating production systems.
• Proven ability to remain technically hands-on through coding, pull request reviews, debugging, and architectural decision-making.
• Experience designing scalable distributed systems, APIs, and reliable cloud-based services.
• Strong understanding of payment lifecycle edge cases, failure recovery, data consistency, and system reliability.
• Experience leading technical initiatives from architecture through production deployment.
• Proficiency with AI-assisted development tools, combined with the ability to independently evaluate generated code and technical solutions.
• Strong communication skills and experience collaborating across engineering, product, and business teams.

Preferred Skills

• Experience with Node.js and TypeScript.
