Your new company
You will be working for an organisation who are based in Glasglow. The requirement for this role is to be on-site 3 days a week. Therefore, candidates who are close to the location are highly desirable and will be considered. The rate is £552 per day inside scope of IR35.

Your new role
Senior Infrastructure Integration EngineerThe Infrastructure-as-a-Service Engineering group in the Core Infrastructure division at this company is responsible for designing, implementing, integrating, and maintaining the firm's large-scale global physical and virtual server infrastructure. The group evaluates, certifies, integrates, and supports a broad range of infrastructure technologies, including hardware platforms, hypervisors, Linux operating systems, system configuration tooling, critical infrastructure services, automation platforms, load-balancing, high availability solutions, and virtualisation management technologies.

We are a key part of the firm's DevOps transformation, delivering real-time APIs and automation
capabilities that enable infrastructure-as-code patterns and provide the back-end integrations
that translate desired state into reliable production outcomes.

We are seeking a skilled and experienced engineer to join the platform engineering team. The role will focus on integrating, testing, securing, and improving multiple infrastructure codebases, with a particular emphasis on vulnerability remediation, code hardening, automated validation, and safe production rollout.

This is not a simple "follow the requirement and apply a fix" role. We are looking for a self-starter who can operate effectively in a complex engineering environment. The successful candidate will need to understand complex distributed systems, assess the broader impact of security changes, design robust remediation approaches, and produce stable, maintainable, and futureproof secure code.

They will also be expected to define appropriate test plans, validate changes in lab environments, and support production rollout with a focus on minimizing risk and stability
impact.

You Will
* Work across multiple infrastructure and automation codebases to remediate identified security vulnerabilities.
* Design, implement, and validate secure, stable, and maintainable code changes.
* Work as an integration engineer, connecting vendor, open-source, and internally developed solutions into the firm's infrastructure platform.
* Develop and maintain automation using Python and related tooling.
* Build and improve CI/CD pipelines, automated test coverage, and release validation processes.
* Create test plans and validation procedures for security-related code and configuration changes.
* Use lab and pre-production environments to test complex changes before production rollout.
* Collaborate with engineering, operations, security, and application teams to assess impact and drive remediation to completion.
* Participate in code reviews, design discussions, documentation, and technical planning.
* Contribute to the ongoing improvement of platform reliability, security posture, and engineering practices.

You Have
* Strong Linux engineering skills, including configuration, troubleshooting, system-level diagnostics, and operational support.
* Solid understanding of distributed systems and the challenges involved in changing, testing, and operating them safely.
* Strong Python development skills, with the ability to write robust, maintainable, production-quality code.
* Experience working with CI/CD pipelines, automated testing frameworks, and release automation.
* Experience with both automated and manual testing approaches.
* Ability to create practical test plans, validation procedures, and rollout plans for complex technical changes.
* Experience working with large-scale production environments and an understanding of operational risk.
* Good understanding of security principles, vulnerability remediation, secure coding, and system hardening.
* Strong troubleshooting skills across operating systems, infrastructure services, automation, networking, and application integration points.
* Ability to work independently, take ownership, and drive complex problems through to resolution.
* Strong communication skills, including the ability to explain technical risks, options, and recommendations clearly.

You May Have
* Experience with Perl in addition to Python.
* Experience with infrastructure-as-code and configuration management tools such as
Ansible, SaltStack, or similar.
* Experience with VMware ESXi, virtualisation platforms, or private cloud infrastructure.
* Experience with vulnerability management, security scanning tools, remediation
workflows, and audit/compliance requirements.
