A senior engineer joins a platform engineering team to integrate, secure, and harden multiple infrastructure codebases — remediating vulnerabilities, writing Python automation, building CI/CD pipelines and test plans, and safely rolling out changes to large-scale Linux production environments. Focus areas include secure coding, automated validation, and risk-minimised production rollout.
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, virtualization platforms, or private cloud infrastructure.
• Experience with vulnerability management, security scanning tools, remediation
workflows, and audit/compliance requirements.
