Job Description

Paymentology is the first truly global issuer-processor, giving banks and fintechs the technology, team and experience to rapidly issue and process Mastercard, Visa and UnionPay cards across more than 60 countries, at scale.

Our advanced, multi-cloud platform, offering both shared and dedicated processing instances, vast global presence and richer, real-time data, set us apart as the leader in payments.

We are looking for an exceptional Site Reliability Engineer (SRE) to join our dedicated team. As an SRE at Paymentology, you will be responsible for maintaining, improving, and ensuring the high availability, scalability, and performance of our platform.

Key Responsibilities:
  • Platform Reliability and Scalability:
    • Design and build software that enhances Paymentology services' scalability and reliability.
    • Ensure platform services meet required uptime and service quality levels.
    • Contribute to the design of reliable cloud infrastructure and implement reusable cloud-uptime components as code.
    • Regularly review and optimise SRE practices, tools, and methodologies to enhance overall system reliability and team efficiency.
  • Observability and Automation:
    • Contribute to the design, implementation, and maintenance of observability and monitoring solutions to track the platform health, its cost-effectiveness, the reliability, and scalability, and identify potential issues which can be fed back to product and platform engineering in a continuous improvement loop.
    • Develop and implement automation scripts and tools to streamline operations and reduce manual interventions.
    • Enable product teams to self-serve by participating in the development of a developer platform.
  • Production Issue Resolution:
    • Play an active role with the incident response teams, diagnosing and resolving production issues quickly to minimise downtime.
  • Standards Compliance:
    • Support product teams in building services that adhere to our security and quality standards.
  • Cross-team Collaboration:
    • Work closely with engineering, operations, and product teams to ensure reliability is considered throughout the end-to-end software development lifecycle. We seek to achieve this through advocacy and developing a culture of reliability.
Requirements:

To succeed in this role, you will need:

  • Bachelor's Degree in Computer Science, Information Technology, or related field.
  • A minimum of 3 years in a dedicated SRE role, as well as 5+ years of prior software development experience.
  • Comprehensive understanding of large-scale distributed platform architecture.
  • Extensive hands-on cloud experience, particularly with AWS.
  • Proven experience developing scalable, modular infrastructure-as-code projects using tools such as Terraform, CloudFormation, Puppet, and Ansible.
  • Practical experience with Docker and container orchestrators, including AWS ECS & EKS, and Kubernetes.
  • Experience in administering or integrating identity management systems for SSO, including AWS IAM, Okta, and Active Directory.
  • Experience with disaster recovery and redundancy strategies in both cloud and on-premises environments.
  • Proficiency with leading monitoring tools, such as Datadog, Honeycomb.io, Splunk, Prometheus, Grafana, ELK Stack, and New Relic.
  • Programming expertise, especially in systems programming languages (e.g., Java, Kotlin, Scala) and databases (e.g., SQL Server, PostgreSQL).
  • Familiarity with industry-leading CI/CD tools such as Jenkins, GitHub Actions, Gitlab CI, CodePipelines, CircleCI, and ArgoCD.
  • Track record of achieving platform-level and end-to-end SLIs, SLOs, and SLAs, and fostering accountability.
  • Ability to navigate complex situations and lead effective post-incident reviews (PIRs).
  • Knowledge of implementing solutions to reduce Mean Time to Identify (MTTI) and Mean Time to Resolve (MTTR).
  • Expertise in implementing best practices for load balancing, fault tolerance, and resource allocation to maintain service quality and efficiency at scale.
  • Understanding of security best practices within cloud environments.
What We Offer:

We offer a range of benefits, including:

  • Full-time remote position with flexible hours.
  • An inclusive and supportive work environment that values diversity.
  • A chance to work on cutting-edge technology projects that make a difference.
  • Opportunities for continuous learning and development.
