Jobs at Unity

Lead architecture and implementation for reliable, scalable AI authoring platforms. Build cloud infrastructure, CI/CD pipelines, Kubernetes and Helm deployments, infrastructure-as-code, observability, disaster recovery, A/B testing, and release processes. Improve backend reliability, performance, security, and cost efficiency across Azure and Google Cloud. Partner with product and engineering teams on technical strategy, ML infrastructure, LLM inference, and AI-assisted game development tools.

Design and implement runtime protocols, formats, and systems to capture, serialize, stream, and replay interactive 3D content across engines. Own C++ runtime and C# APIs across editor, build, simulation, streaming, and playback. Optimize for low-latency, determinism, memory and bandwidth constraints, and build AI interfaces for inspecting and invoking engine state.

Serve as primary legal counsel for Unity’s AI products, advertising monetization, data rights, identity frameworks, and privacy matters. Counsel product, engineering, and data-science teams; draft and negotiate technology, partnership, research, and data-sharing agreements; establish positions on AI, intellectual property, privacy, and emerging regulation; and create scalable legal templates, playbooks, and guidance.

Lead end-to-end machine learning architecture, production systems, forecasting, probabilistic modeling, experimentation, and agentic AI development. Build models for acquisition cost, lifetime value, ROAS, demand, and market outcomes; establish reproducible data and model pipelines; create evaluation harnesses for LLM agents; and own calibration, feedback loops, measurement, and cost controls. Mentor cross-disciplinary engineers and influence technical strategy across teams.

Own end-to-end product marketing for assigned Unity product areas and launches. Develop positioning, messaging, go-to-market plans, audience definitions, sales enablement, partner marketing, competitive intelligence, and developer-focused content. Measure launch performance and translate customer feedback into actionable insights. The role requires independent execution, strong technical writing, comfort with ambiguity, data literacy, and practical use of AI tools. Game production, developer-platform, AI/ML, partner marketing, and contract experience are advantageous.

Build relationships with trade and consumer press, creators, streamers, and podcasters; translate technical news into compelling stories; coordinate integrated PR, social, creator, and community campaigns; and measure communications performance.

Build and maintain large-scale user understanding, ad ranking, conversion prediction, and recommendation models. Monitor model quality, calibrate predictions, address data drift and delayed feedback, and guide engineering design and project execution. Collaborate with technical and non-technical stakeholders to improve advertising performance, user engagement, bidding strategies, and return on ad spend.

Build and evolve Unity’s PolySpatial core technology across low-level C++ and high-level C# systems. Design high-performance APIs for embedded, cross-process, and networked environments; manage execution timing and resource contention; and synchronize assets and components under bandwidth and latency constraints. Responsibilities include engine architecture, serialization, runtime performance, multithreading, networking, and end-to-end implementation and debugging.

Design, deploy, and operate distributed backend systems supporting large-scale, low-latency machine learning inference. Lead inference platform direction, optimize high-throughput serving infrastructure, collaborate with ML engineers, and ensure production reliability through monitoring and observability. Manage GCP cloud infrastructure and Kubernetes workloads while applying DevOps, SRE, testing, deployment, and security best practices.

Own the quality strategy and release gate for Unity’s Gaming AI organization. Build AI-native testing, evaluation, defect intelligence, test automation, and quality measurement systems across frontend, backend, and dependent systems. Establish methods for evaluating nondeterministic AI outputs, including correctness, latency, cost, and consistency. Lead through influence across engineering, art, and product while connecting quality investments to creator and player outcomes and making evidence-based release decisions under schedule pressure.

Design and scale real-time bidding systems, auction mechanisms, bid forecasting, pacing algorithms, and marketplace intelligence models. Apply machine learning, reinforcement learning, control theory, experimentation, and large-scale data analysis to optimize advertiser returns. Lead projects from architecture through offline evaluation and online A/B testing, collaborating with product, infrastructure, and engineering teams to deliver measurable business impact.

Design and lead large-scale machine learning and backend systems for advertiser growth, including budget pacing algorithms, GenAI creative generation infrastructure, marketplace experimentation, high-throughput billing pipelines, and real-time stream processing. Analyze marketplace and financial data, optimize advertiser performance, ensure billing accuracy and fault tolerance, lead multi-quarter technical roadmaps, and mentor senior engineers.

Lead GTM for Unity Grow: define customer personas, craft positioning and messaging for AI/ML-powered ad products, run launches and sales enablement, surface voice-of-customer insights to inform roadmap, and drive external thought leadership and awareness.

Own strategic relationships with approximately 10–15 advertisers and publishers across Unity’s advertising ecosystem. Drive revenue through user acquisition, app monetization, pipeline development, quarterly quotas, executive partnerships, data-driven recommendations, QBRs, and strategic growth plans.
