Frontend Developer (Vue 3, TypeScript)

Kleos is a fast-growing global HR-tech and fintech platform specializing in global payroll. We help 600+ companies manage payments to contractors and remote employees across 200+ countries. Over $100 million in international payments has already been processed through our platform.

We’re looking for an experienced Frontend Developer to join our Contractor Payments team. We’re building a product that enables companies to work directly with international contractors, while Kleos handles invoicing, payments, and compliance.

We’re looking for someone who goes beyond implementing tasks — someone who can independently design solutions, influence frontend architecture, and take ownership of the quality of features delivered to production.

What We’re Looking For

• 4–5+ years of professional frontend development experience, including at least 2 years of production experience with Vue 3 and TypeScript.

• Strong experience with REST APIs, including API contracts, error handling, asynchronous operations, and edge cases.
• Experience writing unit and component tests as an integral part of the development process.
• Ability to turn Figma designs into production-ready interfaces, covering all relevant states: loading, empty, error, and permissions.
• Experience conducting code reviews, refactoring, and improving existing technical solutions.
• Strong ownership and independence: ability to make well-reasoned technical decisions, identify risks, suggest improvements, and take responsibility for outcomes, not just code delivery.
• Hands-on experience using AI coding assistants (Cursor, Claude Code, Copilot, etc.) in real development workflows.
• Understanding of frontend security, including XSS, CSRF, and secure handling of sensitive data.
• Experience building complex B2B SaaS applications.
• Experience with frontend error and performance monitoring tools such as Grafana Faro or Sentry.
