Python Automation Developer

Python Automation Developer – Miller Maxwell is working with a leading electronic trading organisation. The client builds almost all its own technology rather than relying on third-party platforms, and that philosophy extends fully into infrastructure. The estate is predominantly physical servers, with a small amount of virtualisation, running Linux throughout and Windows on desktops and select servers. You’d join a small, close-knit engineering group and take ownership of an internally built provisioning platform, with a broad mandate to extend automation across the wider stack.

• Own and evolve an internally developed Python-based system for building and managing Linux servers.
• Introduce a modern secrets-management layer (Vault-compatible tooling) to replace manual credential handling.
• Speed up patching and lifecycle management across the Linux fleet.
• Move network and firewall configuration into version control, with changes shipped through peer-reviewed pull requests.
• Improve how internal applications are built, tested and released.
• Build a repeatable, hardened setup process for Windows desktops and a handful of Windows servers.
• Bring a small cloud footprint (productivity suite + a major public cloud provider) under the same automated, code-driven management as everything else.
• Improve alerting and monitoring so faults are caught before they cause impact.
• Pair with, and review work from, other engineers on the team.

The skills required for the Python Automation Developer:

• A degree in a STEM related subject.
• 5 + years commercial experience.
• Financial experience is not required; however, Python Automation Developers with this experience will be considered.
• Excellent commercial Python experience – this is the primary language used across the automation estate.
• Familiarity with provisioning physical servers directly, along with experience in virtualised environments.
• Comfort managing infrastructure as code.
• Monitoring/observability tooling experience.
• Windows automation or Active Directory experience is useful but not required.
• Comfortable using AI tools responsibly to speed up engineering work.

What the client offers:

• Highly competitive discretionary bonus.
• Pension contribution.
• Private medical insurance.
• 25 days annual leave.
• Wellness package and gym allowance.
• Life assurance.
• The chance to work closely with a highly experienced, technically deep team where your contribution has direct, visible impact.
• 4 days in the office per week are required.
