Full Job Description

đź“‹ Description

  • • Own the entire frontend stack for a brand-new security product incubated inside Surfshark. You will architect, build, and continuously evolve web applications from zero to global scale, making every technical decision that shapes the user experience.
  • • Design and implement a long-term frontend vision that balances speed of delivery with future-proof scalability. You will choose the frameworks, libraries, and tooling that best serve the product’s ambitious roadmap while ensuring maintainability and performance under rapid growth.
  • • Write clean, efficient, and maintainable code that sets the bar for engineering excellence across the company. Establish coding standards, automated testing strategies, and CI/CD pipelines that allow the team to ship confidently multiple times per day.
  • • Collaborate tightly with backend engineers, product managers, UX designers, and marketing to translate complex security concepts into intuitive, delightful user journeys. Your work will directly influence conversion funnels, onboarding flows, and the overall brand perception of Surfshark’s next big thing.
  • • Champion responsive design and cross-browser compatibility so the product feels native on every device—from the latest flagship phone to an aging office laptop in a remote cafĂ©. You will obsess over performance budgets, accessibility, and SEO to maximize reach and engagement.
  • • Embrace uncertainty and rapid iteration. In this incubator environment, requirements evolve weekly; your ability to pivot gracefully, validate hypotheses quickly, and discard what doesn’t work is as valuable as the code you ship.
  • • Mentor and up-skill fellow engineers through code reviews, pair programming, and internal tech talks. Your influence will extend beyond your own keyboard, shaping a culture of craftsmanship and continuous learning.
  • • Instrument analytics and user-feedback loops that turn qualitative insights into measurable product improvements. You will run A/B tests, analyze funnel data, and iterate relentlessly to hit ambitious KPIs.
  • • Contribute to open-source projects and represent Surfshark at conferences and meetups, amplifying both your personal brand and the company’s reputation in the global tech community.
  • • Enjoy the creative freedom of a startup backed by the resources, stability, and user base of an established cybersecurity leader. You get the best of both worlds: zero red tape and zero fear of running out of runway.
