This is the job

We are looking for an experienced Golang Developer to take a lead role in building and optimizing high-throughput bidding systems within the context of programmatic advertising. You’ll be responsible for designing and evolving bidder infrastructure, collaborating directly with clients, and ensuring systems meet strict low-latency and real-time requirements.

This is you

  • 5+ years of backend experience, with 3+ years of Go (Golang) in production.
  • Strong grasp of idiomatic Go, interfaces, goroutines, and testing.
  • Proficiency in concurrency: mutexes, channels, race condition avoidance, and throughput tuning.
  • Experience building and scaling HTTP and REST APIs.
  • Familiarity with gRPC and Protocol Buffers (nice to have).
  • Deep understanding of low-latency, high-throughput system design (100k+ QPS preferred).
  • Experience with profiling and debugging tools: pprof, trace, memory and CPU bottleneck identification.
  • Competence with caching strategies, load balancing, and performance benchmarking.
  • Hands-on experience with OpenRTB protocol and real-time bidder infrastructure.
  • In-depth understanding of the programmatic ad ecosystem, especially DSPs and RTB mechanics.
  • Experience with containerization: Docker & Docker Compose (multi-container setups, efficient Dockerfiles).
  • Familiarity with AWS (or similar cloud platforms): EC2, S3, Kinesis, Lambda, IAM, and VPC basics.
  • Knowledge of metrics and observability tools like Prometheus and Grafana.
  • Comfortable with Git workflows, shell scripting, and handling CI/CD pipelines.
