Role Description We’re a security-first fintech scale-up building a globally distributed platform, and we’re looking for a Senior DevOps Engineer to help scale and mature our AWS infrastructure. Reporting to the Head of DevOps, you’ll take ownership of AWS platforms supporting multiple environments and services. You’ll focus on improving resilience, scalability, cost efficiency, and developer experience, while driving standardisation through infrastructure as code and platform best practices. This is a hands-on role where you’ll collaborate closely with Engineering, WebApps, QA, and Security teams to build systems that are robust, observable, and aligned with AWS best practices and the Well-Architected Framework. What You’ll Be Doing - Design, build, and manage AWS infrastructure using Terraform, with a focus on reusable modules and standardisation - Operate and optimise AWS services including ECS, EC2, Lambda, SQS/DLQ, CloudWatch, IAM - Develop and improve CI/CD pipelines (GitHub Actions, CodeDeploy) for consistent, reliable deployments - Build and enhance observability frameworks (logging, monitoring, alerting) across distributed systems - Implement and manage identity and access controls, including SSO and access brokering - Collaborate with Security on platform hardening and integration with security tooling (e.g. SIEM, DLP) - Contribute to platform engineering initiatives - Drive cost optimisation efforts across AWS (rightsizing, reserved capacity, scaling strategies, and cost visibility) - Troubleshoot production issues, perform root cause analysis, and implement long-term fixes - Continuously improve infrastructure through automation, documentation, and best practices - Working closely with Engineering team to design, deploy, harden and consistently keep secure containerisation and deployment - Working with Compliance teams on PCI DSS, ISO27001 and SOC2 standards, making sure infrastructure is compliant Qualifications - Strong experience as a Senior DevOps / Platform Engineer in AWS environments - Deep hands-on expertise with AWS services (ECS, EC2, Lambda, IAM, CloudWatch, SQS, etc.) - Strong knowledge of AWS networking (VPC design, routing, security groups, NACLs, private/public architectures) - Proven experience with Terraform, including building reusable modules - Openness to and experience with infrastructure-as-code approaches, with Terraform preferred but alternative IaC tools considered - Solid understanding of AWS Well-Architected Framework and cloud best practices - Experience designing and operating multi-region architectures - Strong CI/CD experience (GitHub Actions, CodeDeploy or similar) - Experience with identity and access management, including SSO - Strong Linux and containerisation knowledge (Docker, ECS) - Experience building and maintaining observability and monitoring systems Requirements - Experience with security tooling integrations (SIEM, DLP, etc.) - Experience working in regulated environments (PCI DSS, ISO 27001, etc.) - Experience with Terraform automation tooling (e.g. Terraform Cloud, Atlantis) - Familiarity with Internal Developer Platforms (IDP) or self-service infrastructure models - Experience with Cloudflare WAF or similar edge security tooling - Exposure to Kubernetes (EKS or Other) - Exposure to Kafka - Familiarity with MongoDB - Scripting or programming experience (any language; Rust a bonus) Benefits - Competitive salary 70,000 DOE - Flexible working hours and remote-first setup - Work-from-abroad flexibility - 28 days holiday + bank holidays - Private medical insurance (including dependants) - Pension contributions - Training, certifications, and professional development support

• Design, build, and maintain continuous integration and continuous delivery (CI/CD) pipelines for rapid, quality-assured deployment of software deliverables • Build and manage Infrastructure as Code (IaC) using tools such as CloudFormation, Ansible, Terraform, Chef, or Puppet • Manage day-to-day operations of release pipelines, build tools, artifact repositories, and source control systems • Coordinate build and release activities with engineering, QA, product, and other stakeholders across the organisation • Identify, research, and prototype new technologies and practices to continuously improve DevOps processes and team efficiency • Maintain and upgrade DevOps systems in both production and non-production environments on an ongoing basis • Proactively monitor infrastructure and application health — including CPU, memory, file systems, databases, batch jobs, and network performance — and respond swiftly to anomalies • Identify and resolve operational issues including infrastructure failures, batch processing errors, network disruptions, and client data feed problems • Troubleshoot and respond to production downtime, performance degradation, and security-related incidents in a timely, structured manner • Perform end-to-end operational duties covering application server health, service availability, and platform integrity in accordance with documented processes and runbooks • Review and manage client service request tickets in adherence to defined SLAs, ensuring accountability and timely resolution • Provide on-call off-hour support as part of a structured rotation, including during non-prime and weekend shift windows as required • Maintain complete and accurate operational documentation including incident tracking, change logs, and runbooks • Produce metric reports and regular productivity/status updates for internal stakeholders and management • Communicate proactively and clearly — both written and verbal — with internal teams, leadership, and customers on a daily basis • Liaise with management to share feedback on existing and new processes, methodologies, best practices, and technology changes • Work efficiently under pressure to meet tight deadlines while maintaining the professionalism, accuracy, and consistency expected in a high-availability environment • Demonstrate a high level of individual accountability and deliver service and support that consistently exceeds client expectations
