Job Description:
We are seeking an experienced Senior Mobile iOS Full-Stack Engineer to join a high-performing engineering team developing large-scale, customer-facing mobile applications. The ideal candidate will have deep expertise in native iOS development combined with strong backend engineering experience. This role requires someone who is comfortable owning features end-to-end—from designing intuitive mobile experiences to integrating with backend services and cloud infrastructure.
If you enjoy building scalable mobile applications, designing robust APIs, and collaborating across the full technology stack, we'd love to hear from you.

Key Responsibilities

Design, develop, and maintain high-performance native iOS applications using Swift, SwiftUI, and/or UIKit.
Build and integrate scalable backend services and APIs supporting mobile applications.
Develop secure and reliable integrations using REST APIs, GraphQL, authentication, and networking frameworks.
Collaborate with product managers, designers, and backend engineers to deliver end-to-end solutions.
Own features throughout the complete software development lifecycle, from design through deployment and production support.
Integrate iOS applications with cloud-based backend services and enterprise systems.
Optimize application performance, scalability, reliability, and user experience.
Participate in architecture discussions, code reviews, testing, and CI/CD processes.
Troubleshoot production issues and continuously improve application quality and system integration.

Required Qualifications

7–10+ years of professional software engineering experience.
4–5+ years of hands-on native iOS development experience.
Strong expertise in Swift, SwiftUI, and/or UIKit.
Experience developing backend applications using Java, Go, Python, Node.js, or similar technologies.
Strong understanding of RESTful APIs, GraphQL, authentication, networking, and system integration.
Experience integrating iOS applications with backend services and cloud platforms.
Proven experience building and supporting large-scale production applications.
Ability to work across the full technology stack—not just mobile development.
Strong problem-solving, communication, and collaboration skills.

Preferred Qualifications

Experience designing backend services or microservices architectures.
Knowledge of mobile CI/CD pipelines and automation.
Experience with cloud platforms such as AWS or Google Cloud Platform (GCP).
Familiarity with Kubernetes and containerized deployments.
Experience optimizing mobile application performance and scalability.
Knowledge of security best practices including OAuth, JWT, and Single Sign-On (SSO).
Startup company experience with the ability to thrive in fast-paced, high-impact environments
