Job Description

We are seeking an experienced Growth Engineer to join a dedicated task force testing a new customer experience concept against the current templated baseline. You’ll own experiment velocity end-to-end: designing tests, instrumenting behavior, shipping variations, and analyzing results – blending technical execution with marketing intuition and behavioral insight.

This is a hands-on, code-shipping role embedded in a product squad. You’ll collaborate with product, engineering, data science, and design daily. Your north star: measurable conversion lift on trip transactions and revenue per trip through rapid, rigorous experimentation across messaging touchpoints.

What Success Looks Like

  • Experiment velocity: Dozens of tests designed, shipped, and conclusively measured within the task force window, with clear learnings from both wins and losses.
  • Measurable lift: 2–3 mechanics identified that demonstrably move trip completion rate or revenue per trip, validated at statistical significance.
  • Instrumentation coverage: Full behavioral funnel visibility from message open through downstream booking action, including cross-vertical attach rate.
  • Playbook delivery: A documented, reusable set of experiment results and growth mechanics the squad can carry forward beyond the task force.
  • Key Responsibilities
  • Experimentation & Optimization
  • Design and run rapid A/B and multivariate experiments across messaging touchpoints (email, push)
  • Build and maintain an experiment backlog prioritized by expected impact, cost, and learning value
  • Analyze results rigorously: statistical significance, segment effects, downstream conversion — not just opens and clicks
  • Instrumentation & Measurement
  • Instrument user behavior end-to-end: message interaction through to booking action, cross-vertical attach, and revenue attribution
  • Define and track experiment-level KPIs aligned with squad north stars (trip completion rate, revenue per trip)
  • Build lightweight dashboards and alerting to surface experiment health and early signals

Technical Execution

  • Ship working variations yourself: messaging templates, personalization logic, behavioral triggers, copy and creative variants
  • Build lightweight tooling and automations to accelerate experiment cycles (scripting, data pipelines, workflow glue)
  • Leverage AI/LLM tools aggressively for ideation, copy generation, audience segmentation, data analysis, and workflow automation
  • Cross-Functional Enablement
  • Product & design: Translate behavioral insights into testable hypotheses and product recommendations
  • Data science/analytics: Partner on experiment design, power calculations, causal inference, and metric definitions
  • Marketing & CRM: Close feedback loops between experiment results and messaging strategy

What We’re Looking For

  • Growth engineering or growth marketing experience (typically 3+ years) delivering measurable acquisition or conversion improvements at scale in a product-led environment
  • Technical fluency: ability to ship working code (Python, JavaScript, SQL at minimum) – you’ve built scrapers, internal tools, automations, or experiment infrastructure, not just configured third-party platforms
  • Strong fluency in experimentation methodology: statistical significance, sample sizing, segmentation, and the difference between a metric moving and a metric mattering
  • Hands-on comfort with SQL and modern data stacks; ability to self-serve analytically without waiting for a data team
  • Understanding of user psychology and behavioral economics – you think in terms of motivation, friction, and timing, not just channels and templates
  • Demonstrated AI-native workflow: active use of LLMs, copilots, and generative tools as daily multipliers, with informed opinions on where they help and where they don’t
  • Experience with messaging/CRM systems at scale and familiarity with deliverability, personalization, and lifecycle orchestration
  • Exposure to multi-vertical or cross-sell environments where success means driving composite value, not single-product conversion
  • Background collaborating with product and data science teams to operationalize signal feedback loops between user behavior and messaging strategy
  • Excellent stakeholder communication across product, engineering, marketing, and analytics; bias toward shipping over planning
