Designs TypeScript and NestJS services, APIs, data contracts, relational schemas, migrations, and event-driven integrations using Kafka and Google Cloud Pub/Sub. Builds React interfaces, operates services on Kubernetes, and improves observability, testing, reliability, and scalability. The role requires ownership of production systems, API correctness, cross-service consistency, design and code review standards, and mentoring other engineers.

Design, build, and operate full-stack advertising platform services using TypeScript, NestJS, React, Kafka, Pub/Sub, and Kubernetes. Own APIs, data contracts, relational schemas, event-driven integrations, observability, reliability, and production operations. Develop scalable user interfaces, maintain data consistency across services, establish engineering standards, conduct reviews, and mentor engineers.

Provides technical leadership for Unity’s high-scale API Gateway platform, including architecture, implementation, testing, operations, incident response, technical planning, and debt reduction. Mentors engineers, drives cross-team initiatives, defines API standards, clarifies ambiguous requirements, and influences technical direction across the organization. The role requires hands-on software development, cloud operations, Kubernetes expertise, and experience building web services and platforms used by multiple engineering teams.

Leads the architecture, development, testing, operation, and long-term evolution of high-traffic API gateway and platform capabilities. Owns reliability, performance, security, incident response, and operational excellence while mentoring engineers and influencing technical direction across teams. Partners with product managers and stakeholders to define strategy, roadmap, API standards, and scalable solutions for Unity’s internal service teams.

Build and operate multi-tenant, cloud-native platform infrastructure (Kubernetes, IaC) to enable hundreds of engineers: tenant isolation, policy enforcement, cost allocation, SOX compliance, secrets management, deployment pipelines, security hardening, and reliability improvements across GCP and multi-cloud environments.

Create, review, and improve technical documentation, including user and developer guides, API references, SDK documentation, and code samples. Partner with engineers and product managers to understand complex technologies and produce clear, accurate, user-focused content. Contribute to content strategy and documentation standards, advocate for users during feature development, and coach less experienced writers while collaborating across a globally distributed team.

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.

Design, build, test, and maintain Unity's monetization backend systems focused on content moderation, fraud prevention, and privacy compliance. Develop low-latency APIs, distributed services, deduplication and labeling tools, and fraud-detection/enrichment pipelines. Collaborate in a remote-first team to deliver scalable, high-quality code and meet project priorities and deadlines.

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.

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.

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.

Design, build, and operate scalable, low-latency backend services and distributed inference systems for internal AI tooling. Architect core services for agent orchestration, manage GCP infrastructure and Kubernetes workloads, implement observability with Prometheus/Grafana, and drive DevOps/SRE best practices across teams.

Join Unity's Monetization team in Montreal to design, implement, test, and improve the Unity Mediation SDK and extend the Unity engine. Own feature lifecycles, write scalable high-quality code and automated tests, mentor teammates, collaborate with distributed cross-functional teams, and build tools (including AI-driven) to enhance developer productivity and monetization capabilities.
