Job Summary

We are looking for an experienced Growth Infrastructure Engineer to build and maintain the technical backbone that enables scalable growth experiments, high-performance data pipelines, and automated systems that drive user acquisition, engagement, and product iteration. This role sits at the intersection of growth, product, and infrastructure — combining deep technical engineering with experimentation and data-driven optimization.

You will collaborate with product, data science, and backend teams to ensure that growth initiatives run smoothly and scale efficiently across systems.

Key Responsibilities

Growth Infrastructure & Systems

  • Design, implement, and maintain scalable infrastructure that supports growth and experimentation needs.

  • Build and optimize analytics pipelines to capture key product and growth metrics (acquisition, activation, retention, etc.).

  • Develop automated workflows for user onboarding, campaign delivery, and performance tracking.

Experimentation & Optimization

  • Support A/B testing frameworks and integrate them into production systems.

  • Enable reliable data collection and evaluation for growth experiments.

  • Automate deployment and rollout of growth feature flags and tests.

Cross-Functional Collaboration

  • Partner with Growth Product Managers, Data Engineers, and Analysts to define technical requirements for growth initiatives.

  • Translate business goals into technical specifications and system designs.

  • Provide guidance on performance, reliability, and scalability trade-offs.

Monitoring & Reliability

  • Implement monitoring and alerting for growth infrastructure services.

  • Troubleshoot production issues and optimize for uptime and performance.

  • Ensure data quality and consistency for reporting and decision-making.

Continuous Improvement

  • Evaluate new tools, frameworks, and platforms that accelerate growth engineering.

  • Drive best practices in infrastructure as code, CI/CD, and automated testing.

  • Train and mentor teammates on growth infrastructure principles. (Teal)

Required Qualifications

  • 3+ years of experience building backend or infrastructure-focused services.

  • Strong programming skills in languages such as Python, Go, or JavaScript.

  • Experience with cloud platform infrastructure (e.g., AWS, GCP, Azure).

  • Solid understanding of data pipelines, ETL processes, and databases.

  • Experience with CI/CD systems and Infrastructure as Code (Terraform, CloudFormation, etc.).

  • Experience with experimentation platforms (StatSig, Segment, LaunchDarkly, or in-house).

Nice to Have

  • Familiarity with growth metrics and product analytics tools (Amplitude, etc.).

  • Experience designing and scaling A/B testing systems and feature flag orchestration.

  • Proficient with containerization (Docker, Kubernetes) and distributed systems.

  • Knowledge of observability tools (Datadog, etc).

What Success Looks Like

  • Growth initiatives that deploy reliably and quickly with minimal manual intervention.

  • High-fidelity data pipelines that enable real-time insight into key growth metrics.

  • Growth teams are empowered to run experiments and launch campaigns without heavy infrastructure support.

Why Join Us?

  • This is a rare opportunity to be among the first engineers on a newly formed Growth team, with significant ownership and influence over both technical direction and product outcomes. You’ll be working on a product that scaled from ~2M to 250M users in under a year, operating in a massive and still largely untapped market. The impact of your work will be visible, measurable, and foundational to how the company grows next.

  • Impact how engineering and product teams scale solutions for millions of users.

  • Competitive compensation and benefits tailored to growth-focused engineers.
