Location: San Mateo (Hybrid)

Dev Ex team builds simulation tools that help Play Station engineers develop, test, and troubleshoot software in a reliable, repeatable environment. These tools shorten feedback cycles, support earlier validation, and make complex development workflows easier to use.

As a Software Engineer II, you will design and deliver capabilities that improve the accuracy, reliability, and usability of our simulation environment. Your work will include simulator functionality, integration with development and test workflows, automation, diagnostics, and the tools engineers use to configure and interact with the environment.

You will own well-defined features from design through rollout, collaborate with engineering and quality teams across Play Station, and turn recurring development and testing challenges into reliable, maintainable product improvements.

• Design, implement, test, and document production-quality C++ features for simulation and developer tooling.
• Build and maintain software abstractions, simulated services, and client/server integrations that reproduce important system behaviors in a development environment.
• Improve core developer workflows such as environment setup, simulator startup, configuration, input handling, debugging, log collection, and failure recovery.
• Improve and contribute to build, dependency, packaging, and release workflows for the simulation platform using modern build tools, dependency managers, containers, and CI/CD pipelines.
• Create unit, integration, and end-to-end tests that catch regressions early and move high-value validation into continuous integration.
• Diagnose failures that cross process, library, container, and platform boundaries; produce clear root-cause analysis and durable fixes.
• Contribute to shared libraries and developer-facing interfaces including versioning, compatibility, migration guidance, and coordination with consuming teams.
• Write architecture notes, setup guides, troubleshooting steps, and release documentation that developers can use without direct support from the team.
• Partner with engineers, QE, product owners, and adjacent platform teams to define integration contracts, sequence cross-team changes, and deliver complete features.
• Participate in design and code reviews, give actionable feedback, and improve the team’s engineering practices through the work you ship.

• Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
• 4+ years of professional software-development experience building systems software, platform software, developer tools, infrastructure or similar technical products.
• Strong modern C++ development skills and practical experience developing and debugging software on Linux.
• Experience debugging multi-process, client/server, or platform-integrated software using logs, traces, debuggers, and reproducible test cases.
• Experience building automated tests and integrating them into CI/CD…
