Job responsibilities

Executes software solutions, design, development, and technical troubleshooting with ability to think beyond routine or conventional approaches to build solutions or breakdown technical problems Creates secure and high-quality production code and maintains algorithms that run synchronously with appropriate systems Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.

g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness. Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.

Produces architecture and design artifacts for complex applications while being accountable for ensuring design constraints are met by software code development Gathers, analyzes, synthesizes, and develops visualizations and reporting from large, diverse data sets in service of continuous improvement of software applications and systems Proactively identifies hidden problems and patterns in data and uses these insights to drive improvements to coding hygiene and system architecture Required qualifications, capabilities, and skills Formal training or certification on software engineering concepts and 3+ years applied experience Experience in developing, debugging, and maintaining code in a large corporate environment with one or more modern programming languages and database querying languages Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.

g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security. Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices.

Design, build, and maintain iOS SDKs (Swift/Objective-C) with clean public APIs, semantic versioning, and backward compatibility. Own SDK architecture & packaging (modular design, dependency management, SPM/Cocoa. Pods), optimizing for simple adoption. Enforce best coding standards: SOLID/protocol-oriented design, readability, documentation, and strong code review practices.

Deliver high performance & stability: thread safety, efficient memory management, caching strategies, and minimal app footprint. Build secure networking and data protection: TLS best practices, safe serialization, Keychain usage, and secure local storage patterns. Overall knowledge of the Software Development Life Cycle Solid understanding of agile methodologies such as CI/CD, Application Resiliency, and Security and Provide strong developer experience & release ops: sample apps, API docs, migration guides, changelogs, deprecation policy, and support.

Preferred qualifications, capabilities, and skills Preferred hands-on Security SDK experience (mobile threat defense, anti-tamper/anti-debug, jailbreak/root detection, RASP concepts). Preferred working with security signals (device integrity, app integrity, runtime environment, anomalous behavior) and signal scoring. Preferred knowledge of attestation and integrity mechanisms (e.

g., Apple App Attest / Device Check concepts) and secure token handling.
