Backend Software Engineer: Swift

W2 Contract

Salary Range: $114,400 - $135,200 per year

Location: Cupertino, CA - Remote Role

Job Summary:

We are seeking highly skilled Swift Backend Engineers to support our growing portfolio of Swift-based service projects. This role focuses on building, maintaining, and modernizing backend services written in Swift, improving the surrounding tooling ecosystem, and contributing to our open-source Swift community. Engineers will operate within a managed-services delivery model, providing lifecycle support, ensuring long-term maintainability, and upholding our engineering standards.

Duties and Responsibilities:

• Design, develop, and maintain backend services using Swift.


• Build scalable service runtimes, APIs, microservices, and cloud-native components.


• Ensure alignment with our internal architectural patterns and best practices.


• Diagnose performance bottlenecks and optimize service behavior in production.


• Support existing Swift workloads already running within our environments.


• Maintain and regularly update sample projects, demo apps, and internal libraries.


• Ensure compatibility with evolving Swift versions, frameworks, and ecosystem tools.


• Provide reliable managed-services support across the full SDLC: monitoring, upgrades, releases, and long-term maintenance.


• Identify gaps in Swift features, evaluation tooling, and runtime capabilities; design technical proposals for improvement.


• Work with AWS SDK for Swift and address friction caused by outdated practices.


• Contribute glue code, utilities, and wrappers required for cloud-native workflows.


• Help close gaps in Swift's data science stack, including clustering, scaling, and distributed compute capabilities.


• Build or extend cloud-native libraries to support ML/GenAI use cases executed on macOS-based environments (e.g., Mac Studio setups).


• Actively contribute to our Swift open-source ecosystem.


• Engage with community proposals, issues, and roadmap discussions.


• Improve internal and external libraries to strengthen long-term maintainability.


• Work closely with our engineering teams to support training and knowledge-transfer efforts.


• Partner with internal teams to help upskill engineers who are transitioning into Swift.


• Contribute documentation, guides, and best-practice playbooks.

Requirements and Qualifications:

• 8-15+ years of backend engineering experience (multiple levels open).


• Strong expertise in Swift, with production experience building backend or cloud-native services.


• Solid understanding of service runtimes, distributed systems, and API design.


• Experience working with AWS or cloud platforms; familiarity with AWS SDK for Swift is a plus.


• Hands-on experience with CI/CD pipelines, observability tooling, and automated testing.


• Ability to contribute to or maintain open-source libraries.


• Strong debugging, performance tuning, and systems thinking skills.

Preferred Qualifications:

• Experience building or maintaining microservices at scale.


• Contributions to the Swift open-source ecosystem.


• Familiarity with data science or ML workflows, especially clustering or distributed computing.


• Understanding of cloud-native glue code, compilers, or runtime internals.


• Experience supporting long-term managed-services models.
