We are looking for an experienced Linux engineer to design and implement a secure, isolated print environment using CUPS. The goal is to build a lean, reliable system that delivers the required functionality without unnecessary complexity or ongoing maintenance overhead.
Project Objectives The system should: Securely handle print jobs Support automatic printing for standard queues Allow manual release for sensitive jobs (e.g. finance) Enable safe re-routing of jobs if a printer is unavailable Ensure jobs are not retained longer than necessary Operate independently without affecting other services Key Requirement: Isolation A critical requirement is strict separation between environments: No visibility of other users’ printers or queues No access to other users’ print jobs No risk of jobs being sent to the wrong printer Strong access control and secure handling Technical Scope You will be responsible for: Setting up an isolated environment (VM preferred) Configuring CUPS with IPPS (TLS encryption) Creating hybrid queue logic (auto-print + hold/release) Implementing lightweight printer health checks Enabling manual fallback routing Applying security hardening and access controls Configuring automatic job cleanup policies Devices Printers include models similar to the following: Toshiba e-STUDIO Katun Arivia
(All expected to support secure IPP/IPPS where possible.) Important Considerations We want to avoid: Overengineered solutions Complex custom scripting where not required High-maintenance or costly components We prefer: Native CUPS functionality Simple, predictable behaviour Low ongoing maintenance What We Expect Before full implementation, you should: Review the scope Recommend the most cost-effective and simplest architecture Identify anything that may increase time or complexity Suggest improvements where needed Deliverables Clear architecture outline Implementation of the agreed setup Documentation of configuration and approach Ideal Candidate Strong experience with Linux systems (AlmaLinux/RHEL-based) Hands-on experience with CUPS and IPP/IPPS Knowledge of secure system design and isolation Ability to deliver simple, practical solutions
Experienced Linux engineer required to design and implement a secure, isolated print environment using CUPS/IPPS. Deliver a lean, reliable solution that securely handles print jobs, supports automatic printing for standard queues, provides hold-and-release for sensitive jobs, enables safe rerouting when printers are unavailable, and enforces timely job cleanup. Implement VM-based isolation, TLS-encrypted IPPS, hybrid queue logic, lightweight health checks, manual fallback routing, hardened access controls, and concise documentation. Recommend simplest cost-effective architecture and identify complexity risks. The ideal candidate has AlmaLinux/RHEL experience, strong CUPS and IPP/IPPS knowledge, and a focus on minimal maintenance and native functionality.
