Senior Software Engineer I (Growth & Marketing Technology)

Responsibilities

• Own implementation and maintenance of ad tracking SDKs and MMPs (for example TikTok, Meta, Google, AppsFlyer), including event mapping and monitoring for signal loss.
• Build and maintain tracking and tag manager setups across web and app so our data is reliable, privacy‑respectful and useful for models and reporting.
• Design, build, test and ship full stack features that support growth (for example landing pages, onboarding flows, referral and promo experiences).
• Integrate and maintain CRM and lifecycle tooling (for example Iterable or similar), including catalogues, data feeds, deeplinks and email / in‑app templates.
• Build internal tools, automations and scripts (for example in Python or Node) that connect systems, improve workflows and power pLTV, dashboards and alerting.
• Collaborate closely with Growth, Marketing and Data to scope experiments and quickly ship A/B tests and campaigns that move key metrics.
• What you'll bring to the team:
• Solid experience as a full stack engineer (ideally 3+ years), comfortable working across frontend and backend.

• Hands‑on experience integrating and maintaining marketing technology such as:
• Analytics and product analytics tools.
• Mobile / web attribution.
• Tag managers and event tracking.
• CRM or lifecycle platforms (email, push, in‑app messaging).
• Comfort working closely with non‑engineering partners (marketing, product, data) and translating business goals into technical solutions.
• A bias towards experimentation and iteration - you care about impact and learning fast.
• Strong ownership mindset: you're happy to take a problem from idea to shipped, monitored solution.
• Good understanding of event tracking, data quality and debugging issues across multiple platforms and tools.
• Bonus points if you have:
• Experience with mobile growth and attribution (for example RevenueCat, app store / play store tooling, mobile attribution providers).
• Previous experience in a product‑led or consumer subscription business.
• Experience with experimentation platforms and A/B testing.
• Familiarity with AWS or another major cloud provider and modern CI/CD practices.
