Create, review, and improve AI-assisted technical documentation, including user guides, developer guides, API references, SDK documentation, and code samples. Partner with engineers and product managers to understand technologies and audiences, contribute to content strategy, advocate for users, and ensure documentation is clear, accurate, concise, and usable. Provide guidance and coaching to less experienced writers while helping establish consistent documentation standards.

Lead design and implementation of a business-critical data platform. Collaborate with stakeholders to define problems, propose technical solutions, own delivery to production, identify reliability issues, deliver architectural improvements, and influence the roadmap to ensure technical excellence in software and data engineering.

Lead a software engineering team supporting Unity on an Android-based device ecosystem. Own execution and technical strategy, optimize Unity runtime performance through benchmarking and analysis, collaborate with engine, platform, graphics, product, and external teams, and communicate progress and vision. Manage, mentor, and develop engineering talent while enabling AI-assisted development workflows and platform-specific experiences.

Develop and maintain a low-latency, high-performance game streaming application across multiple platforms. Responsibilities include UI, video encoding and decoding, networking, input devices, video rendering, UDP protocols, and production C development. The role involves solving complex performance challenges, deploying code to millions of users, collaborating with a globally distributed team, mentoring engineers, and responding to customer needs.

Creates high-quality graphic and motion design for Unity’s brand, campaigns, product launches, social media, events, and marketing initiatives. Translates complex technical and business ideas into compelling visual stories, evolves brand systems, collaborates with cross-functional creative teams, and delivers production-ready assets across digital, print, presentation, and event formats. The role also explores AI-assisted workflows and emerging creative technologies.

Own the quality strategy for Unity’s Android platform support across mobile, laptop, and hybrid devices. Develop test plans, automated and exploratory test suites, performance benchmarks, monitoring dashboards, and platform coverage. Analyze bugs and regressions, convert reports into automated tests, collaborate with automation teams and external partners, and validate runtime optimizations. The role requires Android testing, C# automation, performance profiling, complex software delivery, and familiarity with graphics performance and game engines.

Develop platform support for Unity across Android mobile, laptop, and hybrid devices. Design scalable editor features, analyze and optimize runtime performance, establish benchmarks, resolve bugs, document technical designs, and improve quality through automated testing and code reviews. The role requires advanced C++, C#, and Android systems programming, experience with platform or runtime systems, multithreaded codebases, cross-language memory management, debugging, profiling, and collaboration across engineering teams.

Leads cross-functional platform engineering initiatives supporting Unity on Android devices. Designs architectures, optimizes runtime performance, establishes benchmarks, resolves complex system-level issues, mentors engineers, contributes to platform roadmaps, documents technical decisions, and participates in design reviews. The role requires advanced C++, C#, and Android systems programming expertise, strong knowledge of computer architecture, multithreading, debugging, profiling, and large-scale platform or runtime systems.

Design and scale AI agent systems in Unity for goal-directed behavior, planning, decision-making, and persistent world modeling. Develop reusable agentic frameworks and ML models, optimize real-time performance, and lead reinforcement learning, NPC planning, and agent memory initiatives. Establish model evaluation and AI safety practices, collaborate across teams, contribute to product strategy, and mentor engineers and researchers.

Design and deliver scalable cloud services and full-stack features for a next-generation game creation platform. Optimize cloud applications, apply service architecture patterns, use agentic AI tools such as Claude Code, and manage CI/CD, monitoring, and database maintenance. The role also drives technical direction, aligns with leadership, and collaborates with AI, infrastructure, and data teams.
