Position Description: At RevX, we operate at scale — handling 5M+ QPS and managing petabytes of data. We are looking for a highly skilled Lead Software Engineer with hands-on experience in building and scaling AdTech systems. You will play a key role in designing and developing robust adtech solutions that support large-scale campaign management, real-time bidding, and analytics.

You'll collaborate closely with engineers, data scientists, and product managers to design, develop, and ship impactful solutions.

Primary Responsibilities:

● Architect and optimize the core DSP bidder to ensure extremely high throughput and strict sub-millisecond latency performance.

● Pioneer the integration of new channels (e.g., mWeb, CTV, DOOH, etc.) into the RTB ecosystem, spearheading the technical strategy to scale them for massive traffic and continuous growth.

● Collaborate with Data Scientists to integrate the DS model into the application.

● Engineer ultra-low latency model inference pipelines and real-time feature extraction for accurate bid pricing and CTR/CVR predictions.

● Provide technical leadership to the development team, perform code reviews, and ensure best practices.

● Translate complex marketing and ad-serving requirements into scalable backend solutions.

● Ensure security, reliability, and compliance across all advertising systems.

● Lead the troubleshooting and triaging of issues with different teams to drive toward root cause identification and resolution.

● Manage and aggressively optimize system resource utilization, including garbage collection tuning, advanced memory management, thread management, and network I/O optimization.

Required Skills:

● Bachelor's or Master's degree in Computer Science, Engineering, or a related field.

● 6+ years of professional software development experience with a strong focus on Java & C/C++.

● Deep understanding of multi-threading, concurrency, and non-blocking network I/O (e.g., Netty, Thrift) is necessary for ultra-low latency environments.

● Proficiency with Unix/Linux systems and shell commands.

● Strong knowledge of relational databases (e.g., MySQL) and experience with large-scale data processing.

● Expertise in distributed in-memory datastores (e.g., Redis, Aerospike) and high-throughput message brokers (e.g., Kafka).

● Familiarity with CI/CD, Git, Docker, and cloud platforms (AWS/ GCP /Azure).

● Excellent communication skills and experience working in agile teams.

Preferred Qualifications:

● Experience with programmatic advertising, RTB, or DSPs is a strong plus.

● Hands-on with cloud platforms (GCP) is a differentiator.

● Knowledge of data warehousing and analytics tools like BigQuery.

● Understanding of GDPR, CCPA, and other privacy regulations in the context of digital advertising.

● Hands-on experience with the OpenRTB protocol.
