Job description

Unity is looking for a Senior Software Developer to join our Vector Ads team, where we build the real-time systems that power Unity’s global advertising platform. This is a high-scale, low-latency environment — processing billions of requests daily to deliver fast, relevant ads to players around the world.

You’ll help build the core services behind ad delivery, bidding, reporting, and analytics. This is a great opportunity for an engineer who’s excited to work on performance-critical systems, collaborate across teams, and grow in a fast-paced environment.

Responsibilities

• Work on scalable, high-availability systems used across Unity’s ads ecosystem
• Collaborate with engineers, product managers, and data teams to deliver new features
• Improve performance, observability, and cost-efficiency of backend systems
• Contribute to architectural decisions and technical direction of the platform

Requirements

• Proven experience building backend services at scale
• Proficiency in Golang and relational databases (e.g., MySQL)
• Familiarity with cloud infrastructure and observability tools (Kubernetes, Ray, etc.)
• Spark & Flink experience
• Understanding of API design, distributed systems, and system reliability

Nice to Have

• Experience in ad tech, programmatic advertising, or real-time bidding systems
• Background with infrastructure-as-code (e.g., Terraform)
• Familiarity with networking, caching, or real-time data pipelines
