Senior Site Reliability Engineer

You’ll work across engineering to continuously improve the reliability, resilience and security of the Ockto platform.

• Design, build and automate secure, scalable AWS infrastructure and deployment pipelines using Infrastructure as Code and CI/CD.

• Drive reliability and resilience through observability (monitoring, logging, alerting), incident response, root cause analysis, and disaster recovery / business continuity.

• Strengthen our cloud security posture and operate the controls behind our SOC 2 and ISO 27001 commitments — IAM, secrets management, hardening, and native tooling such as GuardDuty, Security Hub and CloudTrail.

• Keep cloud cost efficient, balancing performance and resilience against spend.

• Drive structured adoption of AI-assisted development workflows (code assistants, automated testing, spec-to-code pipelines).

• Uphold privacy and ethical standards, recognising the responsibility that comes with managing people’s most personal data.

What we are looking for:

• 5+ years of experience in Site Reliability Engineering, Platform Engineering, Cloud Engineering or DevOps.

• Strong hands-on experience with AWS.

• Experience with Infrastructure as Code (Terraform, AWS CDK or CloudFormation).

• Experience with Linux, networking and cloud-native architectures.

• Experience with CI/CD, monitoring and observability.

• Experience securing cloud platforms using IAM, secrets management and infrastructure hardening.

• Experience with scripting or programming (Python, Go, Bash or PowerShell).

• Strong analytical and troubleshooting skills.

• A passion for automation, reliability and continuous improvement.

Will be a plus:

• Experience with AWS security tooling (Security Hub, GuardDuty, Inspector or CloudTrail).

• Experience with SOC 2, ISO 27001 or other security frameworks.

• Experience in fintech or another regulated environment.

• Experience introducing AI-assisted tooling responsibly in a regulated or data-sensitive environment (data-leakage awareness, prompt and secrets hygiene).

• Experience with Kubernetes and container orchestration.

• Serverless architectures (AWS Lambda, API Gateway, EventBridge).

• Experience with Docker.

• Familiarity with operational-resilience requirements such as DORA.
