Job summary

CommonAI CIC is seeking engineers to develop and connect simulation components for AI infrastructure comparisons. You will work with partners to extend and connect existing frameworks through clear interfaces, modeling system states and resource usage to ensure accurate predictions against measurements.

Join a hybrid team with a startup pace, contributing to reproducible simulations, tests, and calibration. Experience in AI runtimes, simulation, and performance modelling is valued.

Qualifications

• Strong software engineering skills with evidence of building, debugging and maintaining substantial software.
• Experience in discrete-event simulation, computer architecture or performance modelling, distributed/HPC systems, inference runtimes and serving, memory or network modelling.
• Ability to understand unfamiliar code, reason about interfaces and assess reuse/extension costs.
• Collaborative testing approach with adjacent specialists.
• Practical experience using AI coding agents and validating their outputs.

Responsibilities

• Develop and integrate simulation components that capture behavior relevant to AI infrastructure comparisons.
• Evaluate existing frameworks and extend components through clear interfaces.
• Model system state and resource use so changes have correct effects elsewhere.
• Build reproducible simulation scenarios, diagnostics and tests to expose issues.
• Compare predictions with measurements, improve models and integrate calibration/uncertainty methods.
• Maintain reliable software, documentation and development workflows with AI coding agents.
