Our top-rated products have won prestigious industry awards for their cutting‑edge technology and seamless client experience. We deliver only the best, so we are always in search of the best people to join our ever‑growing talented team.

Overview

We're looking for a Senior DevOps/SRE Engineer to join our DevOps team and take end‑to‑end ownership of our cloud and on‑premise environments. You will be a key contributor to building scalable, reliable, and secure systems that power our trading platform at a global scale. This is a hands‑on role: you'll architect and operate cloud infrastructure, drive automation and observability excellence, build robust CI/CD pipelines, and help shape the engineering culture around reliability and operational best practices.

Responsibilities

• Design, deploy, and maintain scalable cloud infrastructure on AWS, ensuring high availability, performance, and security across all environments
• Own and evolve Kubernetes cluster management — including bare‑metal deployments — and ensure reliable containerised workloads using Docker and Helm
• Build and maintain CI/CD pipelines using GitLab CI, incorporating GitOps principles with FluxCD or ArgoCD to streamline and automate delivery workflows
• Define and manage Infrastructure as Code using Terraform, ensuring all infrastructure changes are version‑controlled, repeatable, and reviewed
• Lead monitoring and observability initiatives: implement and maintain dashboards, alerting, and log pipelines using VictoriaMetrics/Prometheus, Grafana, and the ELK stack
• Operate and optimize Apache Kafka ecosystems, including Strimzi, Kafka Connect, and MirrorMaker, to support real‑time data pipelines
• Drive incident response, root cause analysis, and post‑mortem culture to continuously improve system reliability
• Collaborate closely with Engineering, Security, and Product teams to embed DevOps best practices across the organisation
• Mentor and guide junior engineers, raising the overall engineering bar for infrastructure reliability and automation

Requirements

• 6+ years of hands‑on experience in a DevOps or SRE role
• Strong knowledge of AWS services, including VPC, EC2, EKS, S3, ECR, EBS, RDS, ElastiCache, IAM, KMS, Secrets Manager, SSM Parameter Store, CloudWatch, MSK, SNS, SQS, Route 53, Direct Connect, Transit Gateway, and ELB/ALB/NLB
• Solid Linux administration skills with deep understanding of system internals
• Deep expertise in Kubernetes, including bare‑metal cluster deployment and day‑2 operations. Proficiency with Docker and Helm
• Hands‑on experience with Terraform as a primary Infrastructure as Code tool — writing, reviewing, and maintaining production‑grade modules
• Proven experience with GitLab CI for building and maintaining CI/CD pipelines; familiarity with GitOps practices using FluxCD or ArgoCD
• Strong background in monitoring and observability: VictoriaMetrics or Prometheus, Grafana, and the ELK stack; solid understanding of log collection and processing with Fluentbit, Fluentd, and Logstash
• Experience operating and managing Apache Kafka ecosystems, including Strimzi, Kafka Connect, and MirrorMaker
• Experience with Ansible for configuration management; experience with AWX is a plus
• Proficiency in scripting and automation with Bash, Python, and Go
• Strong communication skills and the ability to collaborate cross‑functionally in a fast‑paced, regulated environment
• English language proficiency
