Senior Software Engineer - Real-Time Bidding (Go / Python / AdTech)
Job Description
Senior Software Engineer | Go, Python & Real-Time Bidding
\n
\n
I’m recruiting for a growing AdTech company looking for a Senior Backend Engineer with deep hands-on experience building real-time programmatic bidding systems.
\n
\n
This is not a general backend role where AdTech experience is simply a plus.
\n
They need someone who understands the architecture and mechanics behind RTB, SSPs, DSP integrations, ad exchanges and OpenRTB — and has actually built or operated these systems in production.
\n
\n
You’ll join the core team responsible for a large-scale programmatic advertising platform processing high volumes of traffic across dozens of services.
\n
\n
What you’ll work on:
\n
- \n
- Architect and build real-time bidding and auction infrastructure
- Develop and scale SSP / DSP integrations and OpenRTB workflows
- Work across bid requests, responses, timeouts, floor pricing and deal mechanics
- Build high-throughput, latency-sensitive backend services
- Help migrate performance-critical systems from Python to Go
- Own major backend initiatives from architecture through production
- Improve scalability, reliability and performance across the ad platform
- Mentor engineers and contribute to architectural direction

- Strong production experience with Go
- Strong production experience with Python
- Deep professional experience in AdTech
- Hands-on experience building RTB platforms, SSPs, DSPs or ad exchanges
- Strong understanding of OpenRTB and programmatic auction mechanics
- Experience with high-scale distributed or latency-sensitive systems
- Ability to operate as a senior IC and hit the ground running

Experience with Kubernetes, Docker, microservices and cloud infrastructure is valuable. GCP is a plus, but experience with any major cloud platform works.
\n
\n
This is a strong opportunity for an experienced AdTech engineer who wants to own technically difficult infrastructure at real scale without the bureaucracy of a massive advertising platform.
