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
Bachelor’s degree in Computer Science, Software Engineering, or related technical field.
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.
