Sioux Technologies Asia; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Sioux Technologies Asia is seeking a highly-skilled Senior CI/CD Engineer based in Asia to speed up builds, improve pipeline reliability, and integrate tests and static analysis into CI for C#/.NET and C++ codebases. You will optimise MSBuild-based builds, manage GitLab pipelines, and collaborate with development, verification, test architects, and IT-DevOps across Europe and Asia.

Today, end-to-end pipelines run around 200 jobs with over 10,000 tests and take about 4 hours.

Qualifications

• Master's or Bachelor's Degree in Information Technology, Computer Engineering, Telecommunications, or relevant discipline.
• At least 5+ years in CI/CD, build engineering or release automation for multi-repository C#/.NET and C++ codebases.
• Deep hands-on experience with MSBuild and .NET Framework 4.x builds on Windows; experience with C++ builds (MSBuild/CMake).
• CI/CD Platform: Strong GitLab CI/CD skills: pipeline authoring, DAGs, multi-project pipelines, caching and artifact management.
• Scripting: Strong PowerShell and Python for pipeline logic, build orchestration and log analysis; our build also includes Python-based simulation.
• Test Execution in CI: Experience splitting, grouping and parallelising long-running test suites, and detecting and managing flaky tests.
• Fluent English for working across regions.

Responsibilities

• Build Performance: Profile and optimise MSBuild-based builds for C#/.NET Framework 4.7 and C++: incremental and parallel builds, NuGet and dependency caching, and removal of bottlenecks.
• Pipeline Design: Design, standardise and maintain reusable GitLab CI pipeline templates across C#, C++ and Python repositories.
• Test & Verification Integration: With the test architect, development and QA/verification leads, embed unit tests, static analysis (Coverity, SonarQube) and automated test bench runs into CI, with clear results reporting.
• Pipeline Reliability & Metrics: Investigate failures, remove flaky builds and tests, and track build time, failure rate and pipeline uptime on dashboards to show improvement.
• Pipeline Operations: Act as first line on the engineering side when pipelines or runners go down: diagnose, restart or re-run jobs, unblock developers, and hand infrastructure issues to IT-DevOps with a clear diagnosis.
• Capacity Input: Give IT-DevOps data-backed requirements for build runners and test environments, based on queue times and job durations.
• Artifact & Release Automation: Automate versioning, release packaging, artifact staging and package registry management.
• Developer Workflow: Advise teams on branching and merge strategies, merge request verification gates and fast feedback loops.
