Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. 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. 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.
