About The Role

We’re looking for a Senior Software Engineer, Growth to help accelerate our product’s impact by building and optimizing the systems that drive acquisition, activation, retention, and monetization.

You’ll be joining a highly collaborative, cross-functional team that works at the intersection of engineering, product, design, and data. This is a high-leverage role where your work will directly shape the company’s growth trajectory. Own the engineering work that drives acquisition and lowers CAC: reliable measurement (client + server), durable identity across web/app, fast landing experiences and micro-tools, and the plumbing that enables rapid experiments and trustworthy attribution..

This role is ideal for someone who thrives in fast-moving environments, enjoys wearing multiple hats (frontend, backend, and data), and loves using creativity and rigor to solve ambiguous growth challenges.

What You’ll Do

  • Design, build, and ship features across the stack (frontend, backend, and data pipelines) to improve conversion, engagement, and retention.

  • Maintain and improve server-side event forwarding, and a clean event schema across marketing site and app.

  • Identity & attribution enablement - Make identity resilient across domains; enforce UTM governance; ensure data needed for rules-based attribution is consistently available.

  • Work with design to build and iterate high-performance landing pages and lightweight micro-tools that capture intent and convert.

  • Partner with product, design, and data to identify high-impact opportunities and rapidly test hypotheses through experiments and A/B testing.

Who You Are

  • 5+ years building production web software with clear business impact.

  • Full-stack fluency: Strong back-end and infra skills (APIs, auth, cookies, HTTP/CDN) with enough front-end to extend Framer and build/track landing pages.

  • Instrumentation end-to-end: Event design, tag management, server-side forwarding, experiment wiring.

  • SEO fundamentals: Core Web Vitals, crawlability/indexing basics, structured data/sitemaps.

  • Fluent in SQL and Python.

  • Strong Product sense: Can turn ambiguous growth ideas into minimal, testable releases and ship quickly without trading correctness.

  • Working familiarity with GTM, ad pixels, and Google Analytics (for integration/QA).

Nice to Haves

  • Mobile growth basics: Deep linking, install attribution concepts, and experience wiring web↔app journeys.

  • Experimentation rigor: Knows how to design trustworthy A/B tests (power, guardrails, sequential testing pitfalls).

  • Attribution literacy: Has shipped or worked closely with multi-touch attribution or MMM, and understands trade-offs of each.

  • Automation/scale: Has built scripts or APIs to automate campaign hygiene, enforce taxonomy, or streamline data QA.

Our Core Technologies Include: Typescript, Javascript, Node.js, Next.js, React, React Native, SQL, Python, Redis, Redux, New Relic, Kubernetes, CSS, AWS, Cypress, Docker, Express

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
