Senior Growth Engineer

About Us

Headlight is a growth marketing agency focused on scaling consumer products through industry-leading performance advertising, creative, and analytics services. We work with innovative start-ups to emerging global brands on an integrated partnership model built on world-class execution and deep strategic collaboration.

We are a fully remote company with teammates across the United States and Canada and pride ourselves on a low-ego, no-BS culture. We are looking for a driven, ambitious candidate who can help us execute on our mission to build a category-leading company that evolves the agency model and pushes the boundaries of digital advertising.

Position Overview

The Senior Growth Engineer position encompasses all aspects of web and mobile analytics pipelines, data engineering, marketing attribution, cloud infrastructure, and machine learning as they pertain to the measurement and optimization of digital marketing campaigns. This is a senior-level position for someone with 5+ years of relevant experience in a marketing technology role, such as marketing engineering, solutions engineering at a marketing technology company, marketing analytics engineering, or a comparable position deeply embedded in the marketing technology ecosystem.

The ideal candidate brings a deep, hands-on understanding of attribution across both app and web environments, including direct experience working with Mobile Measurement Partners (MMPs) such as AppsFlyer, Adjust, Branch, or Kochava. You should have a strong grasp of incrementality testing methodologies, particularly matched-market (geo-lift) experimentation, and some exposure to Marketing Mix Modeling (MMM) concepts and tools. Demonstrated proficiency and experience with Python, SQL, and Git are core expectations for the role. The ideal candidate will also have experience in client-facing roles, as client consultation and support are core aspects of the position.

Most importantly, we are looking for a diligent and curious learner who will thrive in a lean, fast-paced, customer-centric environment. As a fully remote company spanning multiple time zones and countries, we rely on a culture of direct accountability and trust and look for teammates who will operate effectively in that context. You must be able to work semi-autonomously and deliver crystal-clear communication in both synchronous and asynchronous formats, with teammates and clients alike. You will be expected to demonstrate a deep familiarity with the marketing technology landscape, including attribution platforms, measurement frameworks, and the tools and infrastructure we use to provide our services.
