Your Impact

• Design, build, and evolve high-quality end-user features used by millions of people worldwide, with a particular focus on native, performance-sensitive application development.
• Contribute to and help lead architectural decisions within your domain, creating scalable, maintainable designs aligned with the broader platform strategy.
• Break down complex product requirements into clear technical designs and executable work, guiding delivery from concept to production.
• Develop robust, well-tested production code. Much of our existing codebase is written in modern C++, and you will be supported in building deeper C++ expertise if your experience comes from another relevant language.
• Improve engineering efficiency through automation, including development tooling, test automation, CI/CD workflows, diagnostics, and repeatable operational processes.
• Use product telemetry, operational data, and customer feedback to investigate issues, identify trends and root causes, and prioritise improvements that measurably enhance reliability and customer experience.
• Define and monitor meaningful engineering and product-quality metrics, turning data into clear recommendations and actions.
• Set high standards for code quality, testing, observability, reliability, security, and operational excellence.
• Mentor engineers through design discussions, pairing, code reviews, constructive feedback, and knowledge sharing.
• Partner closely with product managers, designers, and other engineering teams to influence roadmap decisions and balance customer value, technical health, and long-term sustainability.
• Use AI-assisted engineering tools thoughtfully to improve productivity and accelerate delivery, while retaining ownership of the quality, security, and correctness of production solutions.
• Bring curiosity, accountability, and positivity, helping to foster a culture of ownership, learning, inclusion, and collaboration.

Minimum Qualifications

• Bachelor’s degree in Computer Science, Electronic Engineering, Software Engineering, another relevant analytical discipline, or equivalent practical experience.
• 7+ years of professional software development experience or equivalent delivering high-quality, production-grade software in complex environments.
• Strong proficiency in at least one relevant programming language, such as C++, Java, Swift, or Objective-C, together with the ability and willingness to work in and develop proficiency with modern C++.
• Strong software design and problem-solving skills, including the ability to evaluate trade-offs and make sound technical decisions.
• Experience contributing to architecture and design discussions and helping teams reach clear, pragmatic decisions.
• Experience with automated testing and a commitment to quality through code reviews, test strategy, observability, operational readiness, and continuous improvement.
• Experience using data, telemetry, logs, or other quantitative evidence to diagnose technical or customer-facing problems and assess the impact of changes.
• Ability to communicate technical concepts clearly to engineers, product partners, and stakeholders with different levels of technical knowledge.

Preferred Qualifications

• Professional experience with modern C++, particularly in a large, long-lived, or cross-platform codebase.
• Experience building native, desktop, real-time, media, collaboration, or other performance-sensitive applications.
• End-to-end development experience in one or more of the following areas:
  • Languages: Modern C++, Python, Swift, TypeScript/JavaScript, Java, Rust, C#, or Objective-C
  • UI frameworks: Qt, Cocoa, React, Angular, or similar
  • Back end: Java/Spring, RESTful APIs, WebSockets, distributed systems, or API design
• Experience creating automation using Python or a similar scripting language for tooling, testing, build pipelines, diagnostics, or operational workflows.
• Practical data-analysis experience using SQL, Python, dashboards, observability platforms, or similar tools to explore data and communicate actionable insights.
• Significant experience contributing to or owning system architecture for large-scale, customer-facing applications.
• Strong experience with unit, integration, and end-to-end testing, including contract testing and test automation in CI/CD pipelines.
• Practical experience with AI-assisted development tools for activities such as design exploration, scaffolding, refactoring, test generation, debugging, or data investigation.
• Strong familiarity with Git, DevOps practices, continuous integration, and continuous delivery.
• Experience developing or optimising applications across Windows, macOS, Linux, or web platforms.
