Infrastructure Developer | Electronic Trading
A leading electronic trading firm builds almost all its own technology, including infrastructure. Miller Maxwell is hiring an Infrastructure Developer to help automate more of it.
The estate is mostly physical Linux servers, some virtualisation, and Windows on desktops and a few servers. You'll take ownership of an internal, Python-based provisioning platform and extend automation across the wider stack, with projects planned through 2027 and beyond.
The Infrastructure Developer will:
- Own and evolve the Python system that builds and manages the Linux fleet
- Introduce proper secrets management (Vault-compatible) to replace manual credentials
- Speed up patching and lifecycle management across the fleet
- Move network and firewall config into version control with PR review
- Improve how internal applications are built, tested and released
- Build a standard, hardened setup for Windows desktops and servers
- Bring the firm's cloud usage under the same automation as everything else
- Improve monitoring and alerting
- Pair with and review other engineers
