What You'll Bring

• Hands-on experience managing and configuring AWS environments — ECS (Fargate), RDS, VPC, S3, API Gateway, Lambda, CloudFront, IAM
• Hands-on Infrastructure-as-Code experience with Terraform or OpenTofu, including established module patterns, state management, and safe handling of destructive changes
• Containerisation experience with Docker, including image optimisation and secure runtime configuration
• Demonstrated experience building and maintaining CI/CD pipelines and deployment automation, including automated testing and rollback
• Strong command-line, scripting and programming ability — Linux, Bash, Git, plus Python, TypeScript or JavaScript — for diagnostics and automation
• Solid grounding in information security best practice, secrets management, system documentation, and operating resilient systems with no single points of failure
• Commercial experience supporting multiple environments under SLA and support commitments
• Practical, current experience using AI coding agents (Claude Code or equivalent) as the primary means of producing code, and the judgement to verify their output rather than trust it

To Thrive in This Role, You'll Be Someone Who:

• Asks "how do I make this impossible to get wrong" rather than "how do I fix this instance"
• Takes proactive initiative on environment health and automation without waiting for direction
• Gets satisfaction from other people shipping safely at speed, and builds controls that unblock rather than obstruct
• Uses AI aggressively while assuming its output is wrong until verified, and encodes that assumption into the checks
• Explains technical issues clearly to non-technical colleagues and, where needed, client contacts
• Stays analytical during high-severity production incidents

Responsibilities

• Implement and maintain the guardrails — designed with the Senior DevOps Architect — that let engineers and non-engineers safely ship AI-generated application and infrastructure code: policy-as-code, protected environments, scoped IAM and blast-radius limits, mandatory automated gates, plan review, drift detection, and clear sandbox-to-production promotion paths.
• Build out and maintain the automated quality control layer to agreed standards, covering static analysis, schema and migration safety checks, dependency and licence scanning, automated code review and integration testing, so unsafe or substandard changes are caught by the system rather than by a person.
• Deploy, maintain and optimise cloud infrastructure, primarily AWS, for Alliants products and clients — delivering 99.9%+ availability, security compliance, and no single points of failure from network through to database. All infrastructure is defined as code in OpenTofu/Terraform.
• Build and maintain CI/CD pipelines that are fast, parallel and self-verifying, with automatic detection of failed deployments and rollback to the last known-good version, reducing release cycle time while driving deployment-related incidents towards zero.
• Implement instrumentation, alerting, dashboards and performance reporting to identify bottlenecks and regressions before they become incidents.
• Apply InfoSec and regulatory standards, including WAF coverage, centrally managed secrets and least-privilege access.
• Manage, troubleshoot and resolve service desk escalations and production incidents, with root-cause analysis and automated prevention of recurrence rather than repeat manual fixes.
• Contribute to cloud cost optimisation, and provide the usage data behind accurate reporting.
• Support internal and client technical teams with hosting and environment queries, communicating performance and incident reports clearly.
• Maintain the templates and standards that make the safe route the easiest route for everyone else.
• Take part in the out-of-hours on-call rota as first responder, currently one week in six.
