Landing Page & CRO Manager (Webflow)

Type: Full-time, Remote

About Lingopie

Lingopie helps people learn languages by watching real TV shows and movies, with interactive subtitles and built-in review. We're a subscription business with a free-trial-first acquisition model, serving learners across many languages.

The role

You own our landing pages end to end. You build and maintain them in Webflow, you run the CRO program that improves them, and you work with the creative team to make each page convert better. This is a hands-on role. You do the work in Webflow yourself, you run the tests yourself, and you own the results.

Responsibilities

Build and maintain the pages

• Own every landing page in Webflow: build new ones, update existing ones, and keep them fast, clean, and mobile-friendly.
• Build a reusable, modular landing page system so we can launch and iterate on new pages quickly instead of starting from scratch each time.
• Make sure pages load fast and work correctly across devices and browsers.

Run the CRO program

• Use analytics and behavior tools (GA4, Microsoft Clarity, heatmaps, session recordings) to find where users drop off and decide what to test next.
• Own conversion rate optimization across our landing pages. Form clear hypotheses, run A/B and multivariate tests, read the results properly, and ship the winners.
• Improve the full path from landing page to registration to free trial, and report on the conversion impact of every change.

Work with the creative team

• Partner with designers and copywriters to turn ideas into better pages. You brief them, build what they design, and test it.
• Bring your own point of view on page structure, layout, messaging hierarchy, and CTAs. You know what makes a page convert.

What you bring

• Expert, hands-on Webflow.
• Deep command of the Webflow CMS and its dynamic side (Collections, dynamic binding, conditional visibility, filtering and sorting, references), interactions, responsive layouts, and clean, maintainable structure.
• Real web development skills, not just point-and-click. You write custom HTML, CSS, and JavaScript to push past Webflow's defaults when a page needs it.
• Real CRO experience. You have run A/B tests on live pages, you understand experiment design and basic statistics, and you can tell a real win from noise.
• Platform-agnostic at the core. Webflow is what we use now, but your skills are not locked to it. If we move to another platform later (for example Framer, a headless CMS, or a coded front end), you can pick it up and own it, because you understand the underlying web, not just one tool.
• Fluent in analytics and behavior tools: GA4, Clarity or similar, heatmaps, and funnels. You let data decide what to test.
• A good eye for conversion-focused design and UX. You can look at a page and see what is costing us signups.
• You work well with designers and copywriters and can turn their work into shipped, tested pages.
• Self-starter who ships fast and owns outcomes. 

Bonus points

• Experience with dedicated A/B testing tools
• Landing page experience for paid acquisition or a subscription / free trial product.
• Figma comfort, so you can work directly from design files.

• Integrate deeply with columnar formats, open table formats, and connectivity drivers.
• Mentor middle engineers, lead code reviews, and set technical standards for the team.
• Contribute to CI/CD architecture and quality processes across Jenkins, containerization, and multi-cloud deployment (GCP, AWS, Azure via Kubernetes / Docker).
• Debug complex, cross-layer issues spanning query planning, distributed execution, memory management, and I/O.
• Partner with US-based engineering leads on design reviews, architectural decisions, and roadmap execution.

REQUIRED QUALIFICATIONS

• Programming: Strong proficiency in Java or C++, with deep understanding of OOP, systems design, memory management, and concurrency. Candidates strong in both are especially valued.
• SQL & Data: Advanced SQL skills and strong understanding of query execution internals — planning, optimization, and operator implementation.
• Data processing systems experience: Demonstrated experience building or extending data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 5+ years in backend/systems software engineering, with a track record of owning significant components.
• CI/CD & DevOps: Solid experience with Jenkins and modern engineering workflows.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and rigorous code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

ABOUT THE CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Senior SDET to lead the design of automated test frameworks and testing strategy for a large-scale distributed data platform. You will own the quality of the query engine, connectivity layer, and backend services end-to-end — from framework architecture through CI/CD infrastructure across all major clouds — and mentor middle engineers on the team.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

RESPONSIBILITIES

• Architect, design, and evolve automated test frameworks in Python / pytest for backend services, REST APIs, and distributed data components.
• Define testing strategy for new features and platform components — coverage, risk assessment, and quality gates.
• Own end-to-end, integration, performance, and regression testing covering SQL query execution, data correctness at scale, and platform APIs.
• Lead performance and load testing efforts with JMeter, including workloads over JDBC / ODBC / Arrow Flightdrivers.
• Design and validate large-scale data testing scenarios — query plans, result correctness across heterogeneous data sources, metadata consistency, and behavior under high concurrency.
• Own CI/CD test pipelines in Jenkins — architect, maintain, and continuously improve.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker; drive automation and reproducibility.
• Investigate complex, cross-layer failures and drive root-cause analysis with engineering.
• Mentor middle SDETs, review test designs, and set quality standards across the team.
• Partner with US-based development leads on shift-left practices, testability, and release readiness.

REQUIRED QUALIFICATIONS

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with deep understanding of OOP, software design principles, and test framework architecture.
• SQL & Data: Advanced SQL skills and strong understanding of relational and analytical data systems, including query execution internals.
• Data-intensive testing experience: Demonstrated experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 5+ years in backend/system test automation, with demonstrated ownership of test strategy and infrastructure.
• CI/CD & DevOps: Solid experience architecting and maintaining Jenkins pipelines and test environments.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes (running workloads, debugging pods, deploying complex environments).
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, defining test strategy, or leading a QA/SDET function.

DESIRED SKILLS

• Deep experience testing REST APIs and backend microservices at scale.
• Hands-on with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines(e.g., Presto, Trino, or similar).
• Strong understanding of modern data lakehouse concepts, open table formats (Apache Iceberg), and data warehousing.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Performance testing with JMeter or comparable load-testing tools at production scale.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Deep understanding of query plan generation, query acceleration / materializations, and metadata integrity in distributed data systems.
• Prior experience leading a QA/SDET function in a data-platform or database engineering environment.
• Please note: We can consider only candidates currently residing in the EU, EEA, or the UK.
