About Subsurface Dynamics

Subsurface Dynamics Inc. is a Calgary-based engineering and technology company building real-time systems for one of the most operationally demanding environments in energy — hydraulic fracturing.

We don’t build dashboards after the fact.

We build systems that run live during operations — where data is messy, decisions matter, and failures are not theoretical.

Our platform processes high-frequency field data in real time to detect issues while pumping is happening — not days later.

We operate at the intersection of:

• Physics-based engineering
• Real-time data systems
• Operational decision-making

Our clients rely on us during active operations — which means reliability, clarity, and speed are not optional.

We’re a small, highly technical team focused on solving real problems, not building generic software.

If you enjoy working on systems where things break, data is imperfect, and the impact is immediate — you’ll fit in well here.

Calgary (preferred) or Remote (Americas time zones)

🎯 Role Summary

We are looking for a QA Engineer to own testing and product quality for our real-time frac monitoring platform.

Your job is to ensure the system works reliably from a user perspective — catching issues before they reach production.

This role focuses on:

• UI behavior
• Workflow correctness
• Regression testing
• Identifying “weird behavior” early

🧱 Responsibilities

🔹 Product & Workflow Testing

• Test core user flows end-to-end (job setup, processing, dashboards)
• Identify broken UI behavior (buttons, states, navigation)
• Catch inconsistent or unexpected system behavior

🔹 Regression Testing

• Build and maintain a regression checklist
• Run tests before every release
• Ensure new changes don’t break existing functionality

🔹 Bug Tracking & Validation

• Log bugs clearly with steps to reproduce
• Work with developers to validate fixes
• Re-test before closing issues

🔹 Release Quality Gate

• Act as final check before production deployment
• Confirm system is stable and usable

🛠 Requirements

Must have:

• Strong attention to detail
• Experience testing web applications
• Ability to think like a user
• Clear communication

Nice to have:

• Basic understanding of APIs / logs
• Experience with bug tracking tools
• Experience with data-heavy systems

🧠 What We Care About

• You notice small issues others miss
• You don’t assume things “should work” — you verify
• You are systematic and consistent
• You take ownership of product quality
