Senior Devops Engineer

Senior DevOps Engineer

In May 2025, Equals Money and Railsr, two established fintech innovators with complementary strengths, came together. This strategic merger unites Equals' proven expertise in currency and payments with Railsr's powerful embedded finance and card-issuing technology. Together, we've created a next-generation financial services platform with the scale, infrastructure, and agility to serve customers across industries and borders.

Backed by regulated infrastructure and advanced payments technology, we're delivering seamless, scalable solutions with the personal service and trusted experience our customers rely on.

The Opportunity

We're looking for a senior-level DevOps Engineer to join and existing team who will be hands-on running and improving our AWS platform, supporting engineering teams, and helping make our systems more secure and reliable. You'll work primarily with Lambda, Fargate, Aurora, VPC and Security Hub, maintain IaC (Terraform, Serverless), and support CI/CD (GitHub Actions, CodeBuild/CodeDeploy). This is a practical, collaborative role — you'll be solving day-to-day operational problems while helping plan and deliver longer-term improvements.

Your Responsibilities

• Operate and troubleshoot production and staging systems in AWS (Lambda, Fargate, Aurora, VPC).
• Maintain and improve CI/CD pipelines using GitHub Actions and AWS CodeBuild/CodeDeploy.
• Author and update Terraform and Serverless configs; review pull requests for infrastructure changes.
• Respond to incidents, follow runbooks, participate in root-cause analysis and implement fixes.
• Work with engineers to onboard services to the platform and provide practical guidance on deployments, observability and cost.
• Implement security best practices: IAM hygiene, Security Hub findings, secrets management and least-privilege changes.
• Build and tune monitoring, alerts, logging and tracing to reduce noise and catch real issues early.
• Automate repetitive tasks (backups, health checks, tidyups) and keep runbooks and docs current.

Your Profile

Attitude & Behaviours

• Collaborative team player who fits into an existing engineering team — shares knowledge, asks questions, and helps peers.
• Takes ownership for services they touch; pragmatic about shipping improvements incrementally.
• Comfortable learning on the job and seeking mentorship when needed.
• Communicates clearly and respectfully during incidents and in day-to-day work.
• Security- and reliability-minded: prefers small, testable changes that reduce risk.

Skills & Experience

• 2–5 years working with AWS services, ideally including Lambda, Fargate (or ECS), Aurora (or RDS), VPC and IAM.
• Hands-on experience with Terraform and/or Serverless Framework for infrastructure as code.
• Practical experience building CI/CD pipelines — GitHub Actions plus familiarity with CodeBuild/CodeDeploy or equivalents.
• Good debugging and scripting skills (Bash, Python, or similar) and comfort with containers/Docker.
• Familiarity with monitoring/observability tools (CloudWatch, X-Ray, or comparable) and writing meaningful alerts.
• Solid understanding of networking basics (subnets, security groups, routing, NAT) and security principles.
• Experience with incident response, postmortems and maintaining runbooks.
• Nice to have: AWS certifications (eg. AWS Certified DevOps Engineer or Solutions Architect) and experience with cost optimisation and database ops for Aurora.
