The opportunity
At Unity, our mission goes beyond democratizing development: we empower creators to grow, monetize, and transform their content into successful ventures. Unity Ads plays a pivotal role in app monetization, helping developers maximize revenue and acquire new users.

Our Unity Exchange Team focuses on providing a highly performant ad exchange. In this role, you'll be developing services and systems to connect the unique supply and demand of our network. We leverage cloud infrastructure to develop fault tolerant distributed systems to service customers in sub second latencies over billions of requests per day. You’ll work on backend services, infrastructure, and data pipelines that drive efficient and reliable ad delivery, collaborating with cross-functional teams to improve performance, observability, and scalability.

What you'll be doing

• Design and implement backend services that power Unity Ads, in collaboration with other engineers, product managers, and data teams.
• Work with Aerospike, Redis, BigQuery, and MongoDB to ensure fast and reliable data access.
• Utilize GCP, Kubernetes (GKE), Terraform, Helm, and Docker to deploy and scale services in a cloud environment.
• Build and maintain multi-region architectures, gRPC-based services, and internal load balancing to optimize ad-serving efficiency.
• Enhance system monitoring through metrics, tracing, logging, alerting, and runbooks to ensure stability and performance.
• Utilize Kafka and event-driven architectures to process large-scale ad requests in real-time.
• Improve developer velocity by automating deployments and testing with GitHub Actions, Jenkins, and Argo Stack, and design and roll out experimental A/B tests for new features.

What we're looking for

• Proficient and strong knowledge of Go, Python, or C++.
• Experience in distributed, high throughput and low latency systems with external database storage.
• Solid understanding of networking concepts such as gRPC, protobuf, and multi-region architectures.
• Experience managing large-scale databases and optimizing data access patterns.
• Hands-on experience with cloud infrastructure (GCP preferred) and Kubernetes-based deployment.
• Familiarity with observability tools for monitoring system performance and troubleshooting.
• Strong problem-solving skills, with the ability to debug, optimize large-scale systems, and drive performance analysis and optimizations.
• A collaborative mindset, with excellent communication skills for working in a cross-functional team.

You might also have

• Experience in the ad tech or gaming industry.
• Strong understanding of Cloud Design Patterns like Pub/Sub, Circuit Breakers, or Throttling.
• Knowledge of cost optimization strategies in cloud environments.

Additional information

• Relocation support is not available for this position.
• Work visa/immigration sponsorship is not available for this position
