Join to apply for the QA Engineer - Machining Strategy role at CloudNC
CloudNC is transforming global manufacturing with AI that accelerates CAM programming, maximises factory output, and empowers machinists to deliver more.
Our core product, CAM Assist, speeds up CNC machining by tackling the most time‑consuming and repetitive parts of the process, from machining strategy to toolpath generation.
It enables machinists to create effective programs in minutes, unlocking their full potential and helping shops increase throughput and improve consistency.
Today, CAM Assist is trusted by over 1,000 machine shops worldwide to enhance their teams’ productivity, resolve skills shortages and help them deliver efficiently for their customers.
Founded in 2015, CloudNC consists of a world‑class team combining expertise in computer science and physical manufacturing, based at our headquarters in London and our factory in Chelmsford.
The technology company is backed by leading venture capital firms Atomico and Episode 1 Ventures, alongside Autodesk and Lockheed Martin as strategic partners.
The role
We are looking for a QA Engineer to join our Machining Strategy Team, focusing on validating and improving our core machining algorithms. This is a highly exploratory and analytical role, ideal for someone who is curious, methodical, and eager to understand how algorithms behave across a diverse range of parts and scenarios.
You’ll play a key part in ensuring our toolpath generation is correct, efficient, and robust by designing, executing, and analysing tests on the algorithms that power CloudNC’s machining intelligence.
This is not a typical software QA role. It sits at the intersection of quality engineering, machining expertise, and data‑driven exploration.
Job Requirements
* Strong analytical and exploratory testing mindset; a desire to dig deep, experiment, and understand system behaviour.
* Proactive and comfortable working in a team or sometimes alone to pursue lines of investigation
* Excellent attention to detail, curiosity, and persistence in identifying subtle quality issues.
* Ability to interpret and communicate complex technical results clearly to engineers and non‑technical stakeholders.
* Some familiarity with programming concepts or scripting (Python or similar), to support test automation or data analysis.
* Background in CNC machining, CAM/CAD systems, or mechanical engineering; this is a major advantage as you’ll be testing algorithms that generate machining toolpaths.
* Previous experience in QA Engineering, particularly in complex algorithmic or simulation‑heavy environments.
* Understanding of QA methodologies (types of tests, coverage strategies, defect management).
* Knowledge of agile software development practices.
* Experience with test frameworks, CI/CD systems, version control (e.g. Git), logging frameworks (e.g. Kibana, Sentry)
Job Responsibilities
* Execute and design exploratory tests to evaluate the performance and quality of CloudNC’s roughing and finishing algorithms.
* Analyse results, identify unexpected algorithm behaviour, and collaborate closely with engineers and researchers to diagnose issues.
* Develop and maintain manual and automated test suites, ensuring coverage across new features and fixes.
* Leverage existing automation frameworks
* Contribute to QA process improvements, helping define standards and best practices for algorithmic testing.
* Work with cross‑functional teams to ensure releases meet functional and performance quality expectations.
Benefits
* Stock Options
* Annual Performance Equity Award
* 28 days of annual leave
* Leading medical plan
* Life Insurance
* Sabbatical leave
* Enhanced primary, secondary and adoption parental pay & leave (maternity/paternity)
We are proud to be an equal opportunity employer, valuing individuality and embracing all people. The success of CloudNC is a result of diversity of thought. We recognise this comes from people truly belonging. We encourage different perspectives and skills to collaborate towards our mission – disrupting the manufacturing industry. We celebrate diversity and continually improve our inclusivity efforts.
