We’re looking for talented and driven people to help us achieve our vision of everyone on earth having access to simple, fast and accurate non-invasive cancer testing.

Purpose Statement

Reporting to the Principal Bioinformatics Engineer, the AWS Platform Engineer will maintain the cloud infrastructure and deployment environments that underpin Nonacus’ clinical and laboratory software systems. Working primarily on AWS using Terraform, the role spans environment provisioning, system operations (SysOps), platform reliability, and cybersecurity. The AWS Platform Engineer works closely with the software development and bioinformatics teams to deliver secure, scalable, and reliable environments within a regulated diagnostics setting.

Key Responsibilities

Cloud infrastructure & platform engineering

• Build, deploy, and maintain application infrastructure on AWS, including compute, containerisation, storage, networking, and authentication.
• Provision and manage development, test, and production environments, ensuring consistency and repeatability.
• Improve platform reliability, availability, and performance across Nonacus’ software systems.

Automation & CI/CD

• Develop and maintain infrastructure-as-code (e.g. Terraform or CloudFormation) to provision environments reliably and reproducibly.
• Build and maintain CI/CD pipelines to support secure, repeatable deployment practices.
• Automate routine operational tasks to reduce manual effort and improve consistency.

Systems operations & reliability (SysOps)

• Monitor platform and application health, respond to incidents, and contribute to root-cause analysis.
• Manage backups, logging, and observability across the estate.
• Support continuous improvement of operational efficiency and uptime.

Security, compliance & documentation

• Implement and maintain cybersecurity controls across the cloud platform, reviewing the security posture periodically as needs evolve.
• Support alignment with applicable standards (e.g. ISO 27001, ISO 13485, ISO 15189, GDPR).
• Maintain clear documentation of infrastructure, configuration, and changes as required by the quality management system, and collaborate across the Nonacus group on cross-functional goals.

Person specification

Essential

• A degree in computer science, software/cloud engineering, or a related discipline, or equivalent practical experience.
• Hands-on experience with AWS core services (e.g. EC2, S3, IAM, VPC), gained professionally or through significant project work.
• Some experience deploying and maintaining application infrastructure.
• Foundational scripting/programming (e.g. Python and/or Bash).
• Experience with, or strong demonstrable interest in, infrastructure-as-code (Terraform or CloudFormation).
• Familiarity with CI/CD tooling (e.g. GitHub Actions, GitLab CI) and version control (Git).
• Understanding of Linux system administration fundamentals.
• Strong problem-solving ability and attention to detail.
• A methodical approach to operations.
• Good communication and collaboration skills.
• Willingness to learn and take on increasing responsibility (in line with the late-junior growth path).

Desirable

• An AWS certification (e.g. AWS Certified Cloud Practitioner, Solutions Architect – Associate, or SysOps Administrator – Associate).
• Experience with containerisation (Docker) and orchestration (e.g. ECS, EKS, or Kubernetes).
• Exposure to regulated software or healthcare data environments (e.g. ISO 13485, ISO 15189, GDPR).
• Monitoring/observability tooling (e.g. CloudWatch, Grafana, Prometheus).
• Awareness of cloud security best practice (e.g. ISO 27001).
• Familiarity with networking concepts and secrets management.
• A proactive ownership mindset and enthusiasm for working in a clinical diagnostics environment.

We’re an equal opportunities employer focused on achieving our mission, with an end output that will ultimately be measured not in dollars & cents, but in the number of human lives saved by early diagnosis made possible by our achievements.
