We are looking for a Senior Backend Engineer to help scale a high-throughput, real-time bidding
platform that sits at the core of our header-bidding and identity products. You will design and
operate Go services that handle very high request volumes with tight latency budgets, working
close to the auction path where milliseconds and correctness both matter.
This is a hands-on engineering role on a fast-growing product. You will own services end to end
— from design and implementation through deployment, observability, and on-call — and
collaborate with product, QA, and business-development colleagues to ship integrations with ad-
tech partners and demand/supply platforms.

Key Requirements:
🔹 Strong, production-level experience writing backend services in Go (Golang), including the
concurrency model, profiling, and performance tuning.
🔹 Demonstrable experience with header bidding — ideally hands-on with Prebid (Prebid
Server adapters, modules, or comparable auction-side work).
🔹 Experience building and operating high-throughput, low-latency distributed systems in
production
🔹 Solid grasp of HTTP/REST, JSON, and server-to-server integration patterns, plus
debugging across the request lifecycle
🔹 Comfort with relational databases (e.g. MySQL / Aurora) and cloud infrastructure (AWS),
including basic observability and deployment workflows
🔹 Pragmatic testing habits and a track record of shipping reliable software with good
operational hygiene
🔹 Strong debugging and problem-solving abilities;
🔹 Experience with CTV/video and post-bid measurement flows
🔹 Exposure to Prebid Server Java or other JVM services (useful for cross-module work). Experience with Kafka/streaming, Redis or similar caching layers, and container
orchestration (Docker/Kubernetes)
🔹 English – Upper-Intermediate or higher

What you will do:
🔹 Design, build, and operate high-throughput Go services on the real-time bidding and
header-bidding path, optimizing for latency, reliability, and cost at scale.
🔹 Develop and maintain Prebid integrations — Prebid Server adapters, bidder/identity
modules, and the supporting backend that powers them.
🔹 Build and harden integrations with ad-tech vendors (SSPs, DSPs, identity, and
measurement partners), including pixel, post-bid, and server-to-server flows
🔹 Profile and tune hot paths: concurrency, memory allocation, connection pooling, caching,
and request fan-out under high QPS
🔹 Own services through their full lifecycle — instrumentation, dashboards, alerting, and
participation in the on-call rotation.
🔹 Partner with product, QA, and business development to scope new partner integrations and
turn requirements into reliable, well-tested code.
🔹 Contribute to architecture decisions, code reviews, and engineering standards across the
Bidfusion team
