Job description

Online interview

Why work with us? 

We’re a US-based cybersecurity startup safeguarding web and mobile applications against sophisticated cyber attacks. Our Session Sentinel automatically re-verifies the user at every action they take, delivering continuous authentication and breach visibility, which makes it an essential tool for enterprise security.

We’re looking for a talented FullStack developer that will play a critical role in making Session Sentinel intuitive, powerful, and tailored to meet market demands. Join us in building a security solution that truly matters!


The Opportunity

As a FullStack developer, you'll contribute to creating the first such tool that protects against both external attackers and malicious insiders. Your work will ensure that any unauthorized privilege change or resource access attempt are detected immediately. 

It’s a unique opportunity to build your cybersecurity track record, gain expertise in a business-critical area, and thrive in a fast-paced startup environment. This is a fixed-term contract role with the potential for extension or transition into a permanent position based on mutual fit and business needs.


You will

  • develop and maintain a sleek, intuitive, and secure admin dashboard for monitoring user security
  • ensure seamless integration between frontend and backend systems, delivering a frictionless user experience
  • optimize performance and data flow across the full stack, establishing high reliability and speed
  • implement seamless backend integration to display key metrics, logs, and system health data
  • conduct usability testing and integrate user feedback to drive ongoing improvements in services features and security
  • apply FullStack security best practices to guard against threats like XSS, CSRF, and SQL Injection
  • document code, workflows, and features for both frontend and backend components to facilitate ongoing development and smooth onboarding
  • identify and manage potential risks, implement mitigation strategies, and proactively address project challenges


You have

  • 5+ years of experience building interactive frontend applications, working in modern JavaScript frameworks such as React, Vue.js, or Angular
  • expertise in UX best practices including wireframes, prototypes, and high-fidelity mockups for complex workflows
  • a proactive and transparent approach to communication with the ability to take ownership of initiatives
  • strong problem-solving skills and creativity to tackle challenging tasks
  • the ability to dive deep into complex areas in the system, propose solutions, and make necessary improvements


You have an advantage with

  • in-depth understanding of security best practices in frontend development
  • proven experience in building highly scalable and reliable applications
  • familiarity with the demands and responsibilities of being part of a startup environment


What you will get

  • salary range based on B2B contract: $48,000 - $66,000 with final compensation determined by skills, knowledge, and abilities
  • flexible work arrangements in a collaborative startup environment
  • a supportive environment that empowers you to do your best work
