Architect and implement robust AWS-based systems that meet high standards for scalability, performance, and security for our Payments and Foreign Exchange (FX) business. This role requires a hands-on cloud architect with extensive AWS expertise, promoting best practices in infrastructure-as-code, security, and DevSecOps within a fast-paced financial technology environment, ensuring alignment with business goals and driving innovation., * As a senior member of the Engineering and Architecture team, collaborate with development teams to design and implement cloud-native application architectures on AWS that are highly available, scalable, and secure, ensuring solutions meet business needs while aligning with cloud best practices and compliance requirements. * Partner with the Platform engineering team to create reusable cloud design patterns and blueprints/modules (Infrastructure as Code templates) for provisioning and hosting applications on AWS to ensure architectural consistency and governance across teams, reducing duplicate efforts. * Design and oversee AWS networking configurations (VPCs, subnets, routing) and multi-account setups. Implement cloud security standards, including network segmentation and security groups, identity & access management, and encryption. * Drive automation across the cloud environment using Infrastructure-as-Code tools such as Terraform and AWS CDK to provision resources in a repeatable manner. * Collaborate with the security team to implement security best practices, including identity management, encryption, compliance (such as GDPR and ISO 27001), and threat detection and vulnerability management (e.g., Inspector, Security Hub, GuardDuty). * Monitor and optimise AWS environments for performance, cost, and efficiency (right-sizing, auto-scaling, etc.). Implement monitoring and logging solutions (such as CloudWatch, CloudTrail, and X-Ray) to track performance and troubleshoot issues. * Provide technical leadership and mentorship to engineering teams, promoting AWS well-architected best practices and guiding engineers in cloud-native design and troubleshooting. * Engage with senior technology leadership and stakeholders to communicate architectural decisions, technical risks, and opportunities. ## Related Videos - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) - [Building Reliable Serverless Applications with AWS CDK and Testing](https://www.wearedevelopers.com/videos/812-building-reliable-serverless-applications-with-aws-cdk-and-testing) - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [The power of Cloud Development Kit (CDK): How to get the most out of it](https://www.wearedevelopers.com/videos/740-the-power-of-cloud-development-kit-cdk-how-to-get-the-most-out-of-it) - [Building Well-Architected applications](https://www.wearedevelopers.com/videos/691-building-well-architected-applications) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Best Companies to work for in London: Top 25 Companies in 2023](https://www.wearedevelopers.com/magazine/187-best-companies-to-work-for-in-london-top-25-companies-in-2023) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence)
