Description

We are building a new team around a biotechnological product for infectious disease diagnostics, pharmaceutical discovery, and microbiome analysis. The team will focus on designing and implementing the distributed, cloud-based SaaS bioinformatics solution for both research and clinical diagnostics.

As an experienced Site Reliability Engineer (SRE), you will be responsible for designing, implementing, and maintaining scalable, secure, and efficient cloud infrastructure solutions. This role involves building and managing Infrastructure as Code (IaC) systems using tools like Terraform, ensuring adherence to security best practices, and managing incident mitigation procedures. As a technical expert, you will design the infrastructure to meet defined Service Level Objectives (SLOs) and apply FinOps principles to manage cost efficiency.

Key Responsibilities

1. Infrastructure Automation & Governance

• • • Design, develop, and maintain Infrastructure as Code solutions using Terraform.
    • Automate infrastructure provisioning, scaling, and configuration management.
    • Establish and enforce IaC standards to ensure the modularity, reusability, and maintainability of configurations.
    • Optimize IaC pipelines for efficiency, reliability, and auditability.
    • Enforce IaC-only governance for all production changes to ensure auditability and security.

2. Cloud Architecture & Optimization

• • • Provide technical expertise in designing and using AWS cloud services to optimize performance and cost.
    • Design highly available and resilient infrastructure solutions across AWS services.
    • Apply Amazon Well-Architected Framework principles across all architectural decisions.
    • Implement and optimize cloud resources by FinOps practices to ensure optimal cost efficiency.

3. CI/CD and Automation

• • • Build and maintain CI/CD pipelines to support automated deployment and testing.
    • Develop automation tools and scripts to reduce manual operational overhead
    • Collaborate with development teams to implement DevOps best practices
    • Create and maintain runbooks and operational documentation

4. Platform Reliability and Compliance

• • • Implement comprehensive monitoring solutions, including Site Performance Monitoring (SPM) and Application Performance Monitoring (APM).
    • Design and implement Service Level Objective (SLO) frameworks to drive platform reliability, release governance, and continuous toil reduction.
    • Develop, test, and manage Business Continuity Plans (BCP) and Disaster Recovery Plans (DRP).
    • Design and implement the automated incident response framework, focusing on mitigation strategies, root cause analysis, and post-incident review processes.
    • Architect and automate governance controls to ensure high-velocity, auditable compliance with highly regulated standards (GxP, HIPAA, GDPR, ISO27001), leveraging DevSecOps to minimize manual audit requirements.
    • Configure and maintain secure and efficient networks, including AWS VPCs, subnets, routing, and security groups.
