• Hands-on experience with databases such as PostgreSQL and Redis in high-performance production environments
• Proven experience building real-time processing systems, event-driven architectures, or large-scale data pipelines
• Strong understanding of security, privacy, and secure software design principles within cloud-based systems
• Ability to independently own complex technical initiatives and drive architecture decisions with minimal oversight
• Experience with CI/CD pipelines, Infrastructure as Code, and modern observability and monitoring practices
• Familiarity with cybersecurity products, privacy-sensitive applications, or regulated environments is highly valued
• Exposure to ML/AI-supported systems and integrations is considered a plus
• Strong communication, collaboration, and problem-solving skills within remote and distributed engineering teams
• Experience designing multi-tenant SaaS platforms or streaming architectures is an advantage

Benefits

• Competitive compensation package including paid vacation and sick leave
• Fully remote work environment with flexible working hours
• Generous home office and equipment allowance
• Option to access coworking spaces or office facilities when preferred
• Opportunity to work alongside globally recognized engineering talent on complex technical challenges
