About Us
 

Peratera is a UK-based fintech company, founded in 2022 and authorised by the FCA as an Electronic Money Institution.

We are building a modern, all-in-one payment platform that enables businesses to manage global payments and financial operations seamlessly.
 

Our solution allows companies to open multi-currency accounts, send and receive payments worldwide, and manage cross-border transactions from a single platform.
 

Our mission is to simplify global finance and remove friction from international business operations.

Your Mission 

As a Senior DevOps / SRE Engineer at Peratera, you will own the reliability and scalability of a live fintech platform processing real financial transactions. You will build and evolve our cloud infrastructure, implement end-to-end observability, and drive automation across deployment and operations - working closely with engineering teams to make systems more resilient, observable, and easy to operate.

Your Tech Environment

You will work in a modern, cloud-native stack with clear ownership and a defined direction:

• Cloud & Infrastructure: AWS (EKS, EC2, RDS, CloudWatch, IAM), Kubernetes, Docker
• CI/CD & IaC: GitLab CI/CD, GitHub Actions, Terraform (or similar)
• Observability: Prometheus + Grafana, CloudWatch → OpenSearch / ELK (target), OpenTelemetry (roadmap)
• Data & Messaging: PostgreSQL, event-driven message brokers (AMQP / Kafka patterns)
• Platform: Java / Spring Boot microservices, high-load financial transaction processing, external bank and payment integrations
   

What You’ll Do 
 

• Design, build, and maintain cloud infrastructure on AWS - EKS, EC2, RDS, CloudWatch, IAM
• Manage and optimise Kubernetes (EKS) clusters for reliability and performance
• Implement and evolve CI/CD pipelines and deployment automation
• Build observability systems - centralised logging, metrics dashboards, alerting, and distributed tracing
• Define and track SLIs, SLOs, and error budgets across platform services
• Lead incident management and response processes; drive post-incident reviews
• Collaborate with engineers to reduce failure points and enable self-healing systems
• Drive infrastructure cost optimisation and efficiency initiatives
• Contribute to security and compliance posture - FCA, PCI DSS requirements
   

What We’re Looking For
 

• 5–7+ years of experience in DevOps, SRE, or Platform Engineering roles
• Strong hands-on experience with AWS and Kubernetes (EKS preferred)
• Proven experience building and maintaining CI/CD pipelines - GitLab CI preferred
• Infrastructure as Code experience - Terraform or equivalent
• Solid understanding of distributed systems, high availability, and fault tolerance
• Experience with monitoring, alerting, and logging systems in production environments
• Ability to configure and setup, Db management close to DBA
• Strong ownership mindset - comfortable working autonomously and taking end-to-end responsibility
• Familiarity with networking fundamentals and cloud security practices
   

Nice to Have
 

• Experience in fintech, payments, or other regulated environments
• Knowledge of PCI DSS compliance requirements
• Hands-on experience with OpenSearch / ELK, Prometheus / Grafana, or OpenTelemetry
• Exposure to event-driven architectures and Kafka / AMQP
• Interest or experience in AIOps or ML-based monitoring and anomaly detection
   

What You’ll Get
 

• Competitive, market-aligned compensation - discussed openly at first interview
• Full ownership of platform reliability on a live fintech product - not a sandbox
• Opportunity to build SRE practices and observability tooling from the ground up
• Exposure to modern cloud-native and  observability stack
• Genuine growth path toward Senior SRE / Platform Lead or Cloud Architect
• Fully remote setup with flexible hours and an international, highly skilled team
