525 Washington Blvd, Jersey City, NJ 07310 3rd floor, Unit 71 (Ad-Shield), 217 Teheran-ro, Yeoksam-dong, Gangnam District, Seoul

Ad-Shield builds next-generation adblock recovery technology that helps publisher restore this lost revenue and turn blocked traffic into a sustainable revenue channel.

We are one of the fastest-growing teams in global ad-tech. With a lean, high-leverage team, we generate millions of dollars in revenue per employee and are scaling an 8-figure net revenue portfolio toward 9-figure potential.

As a Software Engineer on the Revenue team, you will work on the hardest technical problems that stand between a new partnership and live revenue: debugging real production environments, identifying root causes across complex web and ad systems, and turning these learning into product and infrastructure improvements.

This is an engineering role first. You will write code, investigate ambiguous failures, improve deployment and diagnostic systems, and work closely with product engineering, account management, and partnerships to make Ad-Shield easier, faster, and more reliable to launch at scale.

In practice, this is one of the highest-impact roles at Ad-Shield through forward‑deployed engineering (FDE): you see real customer environments, discover where the systems are not enough, and push those learnings back into the product and platform. Every fix you ship can unlock new revenue and improve the product for every future customer.

As more coding gets automated, the hard part of engineering becomes understanding real‑world client problems and designing systems around them. This role puts you directly in that lane and empowers you to develop human judgment about which problems matter and how to keep systems working for live customers, a combination that is hard to automate and valuable in any future role.

Own Root Cause and Problem Space: You will trace ambiguous issues to their true source, understand why they happened, and decide whether the right resolution is a code change, configuration strategy, monitoring improvement, product enhancement, or a clear technical explanation that helps Account Managers guide the customer. Partner Internally, Own the Technical Path: Work closely with Partnership Managers and Clients to understand issue context, ask the right technical questions, and provide clear internal findings. PMs own customer conversations; Improve Launch Reliability at Scale: Help Ad‑Shield move from issue‑by‑issue debugging to scalable launch infrastructure. You will reduce repeated debugging, catch problems earlier, and make each future customer launch faster and more predictable by designing systems that assume real‑world mess, not perfect configs.

Strong Software Engineering Fundamentals: You are comfortable reading, debugging, and writing production-quality code. We care more about problem-solving ability than years of experience, but you should have strong fundamentals in software systems, debugging, and technical reasoning.

You can form hypotheses, inspect logs, reproduce issues, analyze network requests, narrow down causes, and make evidence-based engineering decisions.

You think about how recurring problems should change the product, tooling, monitoring, or internal workflow so the same issue becomes easier to detect or impossible to repeat.

You understand that engineering work should improve launch speed, customer activation, recovered revenue, reliability, or operational leverage.

Clear English Communication: Professional written and verbal English is required. Korean fluency is a plus, but not required.

AdTech or Publisher Monetization Experience: Familiarity with Google Ad Manager, Prebid, header bidding, programmatic advertising, or ad blockers.

Edge or Infrastructure Experience: Familiarity with Cloudflare Workers, CDNs, caching, edge computing, or web security models.
