• Review and guide API design (REST, Webhooks, etc.) to ensure clean, consistent, and versioned interfaces across teams and external partners
• Help facilitate cross-team architectural alignment and knowledge sharing through regular design reviews and technical discussions
• Support compliance, security, and data governance requirements from an architectural perspective (e.g., data flow diagrams, access controls)
• Stay current with emerging technologies, tools, and architectural patterns to inform long-term platform evolution
• Serve as a key thought partner in Blockskye’s transition from a startup architecture to an enterprise-grade platform

• Bachelor’s degree in Computer Science, Software Engineering, or a related field; advanced degree preferred
• 8+ years of progressive experience in software development, including at least 2–3 years in an architecture or senior technical leadership role
• Deep expertise in backend development with modern frameworks such as Laravel/PHP and Node.js
• Strong understanding of software architecture patterns, including microservices, event-driven systems, and domain-driven design
• Demonstrated experience designing scalable, cloud-native systems, particularly on AWS (e.g., Lambda, RDS, S3, ECS/Fargate)
• Proficiency in designing and maintaining secure, maintainable, and well-documented RESTful APIs and system interfaces
• Strong working knowledge of databases, including MySQL and caching strategies (e.g., Redis), with experience in query optimization and data modeling
• Experience with CI/CD pipelines, infrastructure-as-code, and observability tools (e.g., CloudWatch, Datadog, Sentry)
• Ability to translate business requirements into high-level system designs and detailed technical specifications
• Proven ability to mentor engineers, lead cross-functional technical discussions, and drive consensus
• Excellent communication and interpersonal skills, with fluency in written and spoken English for remote collaboration
• Comfort operating in a remote-first, startup-to-scaleup environment with evolving systems and priorities
• A collaborative mindset and a strong sense of ownership, quality, and continuous improvement

Bonus Qualifications:

• Experience with blockchain technologies, smart contracts, or distributed ledger integrations
• Background in travel, fintech, or enterprise SaaS platforms
