Job description

Role overview

A distributed, fully-remote engineering team that has spent more than a decade building an open-source cloud and edge computing platform is hiring a senior full-stack developer. The role centers on developing and maintaining the platform's web-based management interface, with a clear emphasis on front-end work while still contributing across the stack. The position suits a self-directed engineer who is comfortable in Linux-based environments and open to gradually expanding into adjacent technical areas such as virtualization, command-line tooling, or back-end services as priorities evolve.

Responsibilities

• Design, build, and ship features for the platform's web interface, with primary focus on front-end development and contributing to back-end components as needed.
• Take ownership of features end-to-end, from requirements through implementation, testing, documentation, and delivery.
• Write well-tested, maintainable code that prioritizes long-term software quality and strong test coverage.
• Diagnose and resolve issues spanning front-end and back-end code in Linux environments.
• Produce clear technical documentation and articulate design decisions to teammates.
• Suggest improvements to the product, codebase, and development workflows, and collaborate across disciplines as priorities shift.

Requirements

• Bachelor's or Master's degree in Computer Science, Information Technology, or Engineering.
• Three or more years of professional software development experience in production environments, with real-world work beyond purely front-end development.
• Hands-on experience building web applications across both front-end and back-end components.
• Practical experience developing and maintaining user-facing web applications.
• Comfort working in Linux-based development environments.
• Ability to work autonomously, communicate technical decisions clearly, and turn loose requirements into production-ready software.

Nice to have

• Exposure to virtualization, networking, or cloud infrastructure concepts.
• Familiarity with command-line tooling, Ruby, or related back-end technologies.
• Curiosity and adaptability to broaden expertise over time into new areas of the stack.

Benefits and work setup

• Competitive compensation with flexible remuneration options covering meals, transport, and childcare.
• Choice of workstation hardware across macOS, Windows, or any Linux distribution.
• Private health insurance coverage.
• Reduced hours on Fridays and throughout August.
• Paid time off for holidays, personal time, sick leave, and parental leave.
• Fully remote organization with headquarters in Madrid and additional offices in Boston and Brno.
• Emphasis on digital disconnection and a healthy work-life balance.
• Flexible hiring arrangements: full-time or part-time, with employment or contractor options depending on location.
• Engineering-first culture that encourages learning new technologies and methods as part of everyday work.
