Company mission
To give thinkers, writers, and creatives the opportunity to pursue their curiosity and make money at the same time.
Role
Who you are
- 10+ years in ad operations, solutions engineering, or technical account management at a platform, publisher, or ad tech company
- Hands-on experience with campaign trafficking, tag management, and third-party measurement or verification vendors — and comfort when the format doesn't fit the vendor's assumptions
- Fluency with data: strong spreadsheet skills at minimum, SQL and scripting a real advantage, and the judgment to know when a number looks wrong
- Experience sitting in on sales calls to answer technical questions and scope feasibility on custom or unfamiliar formats in real time
- The range to debug a delivery discrepancy with an agency in the morning and spec an internal tool with an engineer in the afternoon
- An operator's instinct for process: you build systems that scale without over-engineering before there's volume to justify it
- Familiarity with how creator sponsorships are sold, delivered, and measured is a plus
- Experience with APIs, workflow automation, or light scripting (Python, JavaScript) is a plus
What the job involves
- We're building Substack's sponsorships business from the ground up. The Implementation Lead makes campaigns scale into a marketplace. You own the operational backbone of the business: campaign workflows, integrations/operations, and marketplace quality that makes it all happen. When a brand’s ad ops team and solutions engineers need to understand each other, you're the translator. This is a founding role on a small team and a build role
- Own trafficking, QA, launch, delivery monitoring for custom sponsorship formats
- Execute on the pipes for the business: order management, campaign workflows, reporting, and billing handoffs
- Implement and maintain the integrations brands expect — tracking, third-party measurement, verification — adapted to formats that standard tags and pixels weren't built for
- Serve as first-line solutions lead for brands and agencies operating in the marketplace, and be the translator when their ad ops team needs to understand how our formats actually work
- Work with design and engineering to decide what deserves real tooling now versus what stays a manual workaround until there's volume to justify automating it
- Contribute to an AI-first outbound and onboarding engine to drive demand into the marketplace
- Write the playbooks and documentation — since for custom formats, the playbook usually doesn't exist until you write it
Our take
Substack is an online platform for journalists and writers to manage subscription-based newsletters. It has attracted a range of users who wish to connect with their audiences in a different way to social media or ad-based models, and boasts more than 35 million subscribers.
For an industry that has seen a steady decline in its fortunes since the rise of digital, Substack is a breath of fresh air. It allows journalists to avoid the clickbait-heavy models that have dominated the last decade, and provides more freedom than its competitors. Users produce their newsletters on the site for free, charging an optional subscription fee of which Substack takes 10%.
The company continues to seek out ways to diversify its offerings, whilst securing funding rounds to expand its reach. It has also taken an outspoken approach to the AI-generated content that is taking over the internet. It already provides its users access to an AI-detection tool, and is exploring other features such as enabling users to opt out of seeing AI-generated content on their feeds altogether.
