Solution Architect

Skills

About the Role

You'll take ownership of solution design for backend systems that power payment products including card acquiring, wallets, crypto, and BaaS. You'll design and maintain architecture that is AI-native and cloud-agnostic, aligned with modern security, scalability, and compliance standards. You'll partner with product managers, engineering leads, QA, and analysts to translate business needs into modular architectural designs. You'll build documentation, high-level solution diagrams, system interface contracts, and component-level specifications. You'll contribute to API design and service decomposition efforts, and guide cloud migration and infrastructure evolution across an AWS-based stack with Kubernetes, GitLab CI/CD, and Terraform. You'll ensure systems enable zero-downtime deployments, automated rollbacks, and scalable horizontal patterns. You'll conduct architectural reviews and technical assessments while working closely with delivery teams to implement designs. You'll act as a thought leader across engineering functions, driving architectural maturity and platform modernization, and proactively identify technical debt and long-term design risks while proposing mitigation strategies.

Requirements

• 6+ years of experience in architecture roles, preferably in fintech or high-availability distributed systems
• Proven experience designing scalable backend systems in AWS or hybrid cloud environments
• Strong hands-on background in backend development (Java), DevOps, or cloud infrastructure
• Deep understanding of distributed systems, event-driven architectures, microservices, CI/CD pipelines, and observability practices (Grafana, Prometheus)
• Solid experience with Kubernetes, Terraform, and GitLab CI/CD
• Experience participating in and driving system design reviews across multiple teams
• Strong stakeholder communication skills and ability to align technical and business requirements
• Comfortable working in fast-paced, cross-functional environments (LATAM, EU, APAC collaboration)
• Practical experience integrating AI/ML components into backend systems (e.g., AI pipelines, agent-based integrations, MLOps)
• Demonstrated awareness of AI-driven engineering practices and emerging AI technologies
• Hands-on experience leveraging AI tools (LLMs, AI-assisted development tools, automation frameworks) to improve productivity, system performance, or architectural decision-making
• Background in financial services, payment gateways, acquiring, digital wallets, or other regulated environments
