Unity Support Engineer (Part-Time)

About the role

Altoros, an IT services provider, is looking for a part-time Unity Support Engineer based in Warsaw. The role focuses on keeping the Unity client compatible with the Django backend, reviewing SDK releases and fixing compatibility issues. It is a 6-12 month engagement starting in August, with a fully paid onboarding of 20 hours between August and October 2026.

Key responsibilities

• Review Unity SDK release notes monthly, identify breaking changes affecting the Django integration and assess their impact on the API contract
• Apply reactive compatibility patches on the Unity client side when SDK updates cause incompatibilities or Django integration failures
• Diagnose incidents such as frozen screens, missing or outdated content, and configuration not reaching the Unity client, propose and implement fixes, and document known issues and workarounds in runbooks
• Collaborate with the backend team and external stakeholders

Required profile

• Proven experience with the Unity SDK, including release cycles, versioning and package upgrades
• Ability to read, analyze and modify C# code in existing Unity projects, focused on debugging and patching rather than building apps from scratch
• Understanding of how a Unity standalone app uses REST APIs (HTTP client, JSON, error handling and retries)
• Ability to reproduce and diagnose runtime issues locally using logs, breakpoints and diagnostic tools
• English at B2+ level, comfortable with technical documentation and clear communication with clients and stakeholders
• Nice to have: Unity in digital signage or kiosk systems, basic Django REST API knowledge, GCP Cloud Run awareness, and remote diagnostics via jump PCs / RDP

Required skills

• C# and Unity SDK
• Unity Package Manager and dependency management
• REST APIs, HTTP client usage and JSON serialization
• Building Unity standalone targets for Windows and/or Linux

Work schedule: Monday to Friday, 15:00-00:00 Warsaw time; the candidate does not need to be present at the monitor but must be able to handle a task within 4 hours to 1 business day. Location: Poland or western Europe.
