Senior Infrastructure Engineer

Oritain
London

Oritain is the global leader in product verification, with locations in Auckland, Dunedin, London, Singapore and Washington D.C.

Our Mission: Science, Technology and Global Impact

Our mission is to protect people and the planet by harnessing science, technology and services to build a community of origin verified suppliers and buyers. As a Senior Infrastructure Engineer, you will be the backbone of this mission, responsible for building, automating, and securing the Microsoft Azure cloud platform that hosts all of our mission-critical software and services.

We are looking for an experienced infrastructure leader to embed best practices, drive automation, and champion a true DevOps culture within our growing software engineering team.

The Opportunity: Automation, Security, Scalability

Working closely with the Head of Engineering and the development squads, you will own the delivery, operational health, and continuous improvement of our cloud platform. This role is a strategic blend of infrastructure architecture, security implementation, and developer enablement.

Key Responsibilities

Cloud Architecture and Infrastructure as Code (IaC)

  • Azure Platform Ownership: Design, implement, and maintain the core architecture of our platform on Microsoft Azure, ensuring high availability, disaster recovery, and cost optimisation.

  • Automation: Lead the development and maintenance of all infrastructure using Infrastructure as Code (IaC) tools, particularly Terraform or Azure Resource Manager (ARM) templates, to achieve immutable and repeatable environments.

  • Security: Implement and enforce cloud security best practices, including network configuration (VNETs, Firewalls), identity management (Azure AD, RBAC), and platform governance.

DevOps and CI/CD Pipeline Management

  • Developer Enablement: Establish and maintain robust, self-service tools and environments that allow software engineers to deploy, monitor, and debug their applications quickly and reliably.

  • CI/CD Pipeline: Own and enhance the continuous integration and continuous deployment (CI/CD) pipelines, primarily using Azure DevOps, to automate code testing, security scanning, and seamless delivery to production.

  • Operational Excellence: Implement comprehensive logging, monitoring, and alerting strategies (e.g., Azure Monitor, Application Insights) to ensure rapid detection and resolution of production issues.

Collaboration and Mentorship

  • Cross-Functional Partnership: Collaborate with the Backend and Frontend Engineers to define service requirements, plan resource scaling, and troubleshoot complex production issues.

  • Technical Guidance: Provide technical mentorship to the wider engineering team on cloud architecture, security principles, and robust operational practices.

  • Documentation: Create and maintain clear, high-quality documentation for infrastructure, deployment processes, and operational runbooks.

The Engineering Environment

  • Work Style: We operate a hybrid model, requiring a minimum of three days per week in our London office to maximise collaboration and platform insight.

  • Technology: We are a Microsoft Azure cloud-native organization. We rely on .NET for services and React/Angular for frontends, all deployed via automated pipelines.

  • Team: You will be the senior voice for infrastructure and DevOps, embedded within a mission-driven software engineering team.

Skills & Experience

  • Senior Cloud Expertise: Significant professional experience (typically 5+years) focused on cloud infrastructure and operations.

  • Azure Depth: Deep, hands-on expertise with a wide range of Microsoft Azure services (e.g., App Service, Functions, Networking, Security Center).

  • Automation Focus: Proven experience building and managing infrastructure using Infrastructure as Code (IaC) tools, with strong preference for Terraform.

  • CI/CD Tools: Expert knowledge and experience administering and optimising CI/CD systems, preferably Azure DevOps Pipelines.

  • Operating Systems & Networking: Strong understanding of Linux/Windows administration, IP networking fundamentals, and cloud-native security concepts.

  • Scripting: Proficiency in scripting languages (e.g., PowerShell, Bash, Python) for automation and operational tasks.

Desirable Attributes

  • Experience working with container technologies (Docker, Kubernetes).

  • Familiarity with compliance standards or regulated environments.

  • Experience in optimising database services (e.g., Azure SQL, Cosmos DB) for performance and cost.

Company Benefits

  • Paid Leave- 35 days (inclusive of public holidays)

  • Birthday Off

  • Volunteering Leave Allowance

  • Enhanced Parental Leave

  • Life Insurance

  • Healthcare Cash Plan

  • Employee Assistance Programme (EAP)

  • Pension

  • Monthly Wellbeing Allowance

  • Breakfast, Snacks, Friday lunch & Barista Coffee Machine in the office

  • Learning Portal with over 100,000 assets available to support professional development

  • Hybrid working set-up (Farringdon, London)

  • Plenty of friendly 4-legged pets in the office!

Please note: we will be winding down for the festive break between Friday 19th December and Monday 5th January. During this time, responses to applications may be slightly delayed.

We appreciate your patience and look forward to connecting with you soon!
