Nord Security is a cybersecurity software company that develops consumer and business privacy tools including NordVPN, NordPass, NordLocker, NordLayer, the Saily eSIM app and the Coveron identity protection service, with its main operations in Vilnius, Lithuania. Founded in 2012 by Tomas Okmanas, Eimantas Sabaliauskas and Jonas Karklys when NordVPN launched, it became a unicorn in 2022 after raising outside capital at a 1.6 billion dollar valuation. Its openings are mostly for backend Go and PHP engineers, site reliability engineers, Android, iOS and Windows developers, QA engineers, threat intelligence researchers and designers.

The world’s most advanced VPN, and a whole lot more.

If you’re a curious problem-solver who carves their own path, join the team behind Threat Protection Pro, the NordLynx protocol, and the fastest VPN on the planet-tools that put privacy, security, and control back in people’s hands.

Your impact? Helping millions take back control of their online security, privacy, and data.

Main Responsibilities

  • Own and manage the entire experimentation lifecycle end-to-end - from idea intake and prioritization to launch, analysis, and documentation - coordinating cross-functional stakeholders (analysts, developers, designers, researchers, copywriters, QA);

  • Act as the project manager for experimentation initiatives: define scope and timelines, manage dependencies across teams, identify and mitigate risks, and ensure experiments ship on schedule;

  • Conduct user behavior analysis based on qualitative and quantitative data sources and provide ideas to increase conversion rate and other relevant metrics (billings, retention, refunds);

  • Create and execute testable, data-driven hypotheses and A/B tests tailored to mobile user journeys (onboarding, paywalls, pricing, checkout flows);

  • Track the performance of mobile funnels, paywalls, and acquisition channels to find actionable insights and react to identified problems and opportunities;

  • Apply an iterative optimization approach based on established patterns, while adapting quickly to shifting priorities and business needs;

  • Perform data analysis of experiments: explain the WHY behind the data and deliver actionable insights to further improve UX, conversion rates, or other relevant metrics;

  • Communicate experiment results, learnings, and next steps clearly to stakeholders and leadership, maintaining a well-documented experimentation knowledge base.

Core Requirements

  • 3+ years hands-on experience in A/B testing/experimentation, ideally with mobile apps (iOS/Android) or mobile web;

  • Strong project management skills: proven ability to plan, prioritize, and deliver multiple concurrent initiatives in cross-functional environments (familiarity with Agile, Jira, Confluence is a plus);

  • Adaptability and ownership: comfortable switching between strategic planning and hands-on execution in a fast-paced, intensely iterative optimization process;

  • Knowledge of statistics related to A/B testing: sample sizes, statistical significance, marketing funnels;

  • Excellent communication and stakeholder management skills;

  • Familiarity with app development processes and release cycles;

  • Hands-on experience with tools like Firebase, Figma, Jira, and Looker;
