About HedgehogHedgehog is a SaaS platform that powers community engagement for major media brands. Our white-label commenting plugin lets publishers host real-time conversations, live chats, and community features directly on their sites and apps, at the scale of high-traffic news and sports properties. We also build a games SDK that brings interactive experiences to those same audiences.

We’re now building our own ad network on top of that engaged audience. Our commenting and community products generate rich first-party data about what readers engage with, discuss, and care about, and we’re using that data to power ad targeting across our publisher partners. That gives advertisers a privacy-conscious alternative to third-party cookies, built on real engagement signals. It’s an early, high-impact product, and this role will shape where it goes.

About the roleWe’re looking for an engineer with real ad network experience to take ownership of our ad platform. A core part of the role is turning the first-party data from our commenting and community products into targeting that advertisers can use: defining audience segments, building the pipelines and logic behind them, and proving that they perform. You’ll also pick up existing work on campaign dashboards and targeting tooling and drive it forward, owning the ad network side end to end.

You’ll work closely with product, sales, and our publisher partners to turn advertiser needs into working features.

How we workWe’re an AI-native team. Claude, and Claude Code in particular, is central to how we design, build, review, and ship software. We expect you to use it every day to move fast, explore unfamiliar code, and handle work across the stack. Because of that, we care more about your domain knowledge and judgment than whether you already know every tool we use.

What you’ll do

- Own the ad network roadmap on the engineering side,



picking up existing work and taking it to production.
- Turn first-party engagement data from our commenting and community products into targetable audience segments and signals.
- Build targeting tooling on top of those segments, including contextual and engagement-based targeting and frequency capping.
- Build campaign management dashboards for advertisers and internal teams: setup, budgets, pacing, scheduling, and reporting.
- Build reporting and analytics on impressions, clicks, conversions, and spend that advertisers can trust.
- Work on ad serving logic and integrate it with our commenting plugin and SDKs.
- Partner with product and sales to understand advertiser and publisher needs and translate them into technical plans.
- Use Claude daily to speed up development, documentation, testing, and code review.

What we’re looking for

- Hands-on experience building ad tech: ad networks, ad servers, DSPs/SSPs, or campaign management platforms.
- Experience working with first-party data for targeting or audience building, such as data management platforms, customer data platforms, or publisher audience products.
- Solid understanding of how campaigns, targeting, auctions or pricing models (CPM, CPC, CPA), and attribution work.
- Experience building data-heavy dashboards and reporting tools.
- Strong analytical and logical thinking, and comfort working with large event datasets.
- Experience using AI coding tools like Claude Code as a core part of your workflow, or a strong willingness to adopt them.
- Ability to work independently and own a product area with limited direction.
- Clear communication in English.

Nice to have

- Strong familiarity with privacy and consent requirements for first-party data in advertising (GDPR, CCPA, TCF).
- Experience with our stack: TypeScript, Bun, React, and Vue.
- Experience with real-time bidding or OpenRTB.
- Experience working with media or publishing companies.
