Any offer made will carefully take into account level of experience (including relevant industry experience), transferable relevant skills and previous relevant achievements.\nAbout us \nRiverlane’s mission is to master quantum error correction (QEC) and unlock a new age of human progress. From advances in material and climate science, to complex chemistry simulation for new drug design, quantum computers will help humanity solve some of its most important challenges. But without QEC, the industry’s defining technical challenge, such breakthroughs can never be achieved. Riverlane is the world leader in QEC technology. QEC is a complex problem that requires a range of skills, talent and passion. \nHaving raised more than $125M in funding to date to accelerate our cutting-edge R&D in quantum error correction (QEC), Riverlane partners with many of the world’s leading quantum hardware providers and government agencies to make fault-tolerant quantum computing a reality. We’re making remarkable progress and growing fast. \nAbout the role: \nWe’re looking for a Software Development Engineer in Test, to join our Test Engineering team in Cambridge. You’ll test Riverlane’s QEC software from end to end, across Deltakit (our open-source Python SDK), our compiler and Deltaflow (our real-time quantum error correction system). \nThis role suits a developer with some experience in quantum, who wants to move towards testing. You’ll write and maintain tests, and you’ll also think like a user: does this feature behave the way a customer would expect, and could it be easier to use? What you learn will feed directly into how we improve the product. \nWhat you will do ( specific responsibilities): \nDesign, write and maintain Python tests (using pytest) across our QEC software stack, including Deltakit and the compiler front end \nTest features from the customer’s point of view, and check that your tests reflect how users will actually work with the product \nSpot where functionality could be clearer or easier to use, and propose improvements \nShare findings with engineering and product teams, and follow your suggestions through to changes in the product \nWork closely with developers to understand new features and plan how they should be tested \nWhat we need:\nKnowledge of quantum computation and core concepts such as quantum circuits. One relevant project or piece of experience is enough (for example, building and running circuits with a framework such as Qiskit) \nExperience as a developer working on a product, either software or hardware, and an interest in moving towards test \nStrong Python skills. All the interfaces you’ll use day to day are in Python, from pytest to our compiler front end and Deltakit \nA user-focused mindset. You think about how functionality comes across to a customer and how it could be made easier to use \nA track record of suggesting improvements to a product or software library \nEven better if you have…\nKnowledge of quantum error correction (QEC) \nDirect experience of testing software or hardware \nWhat can you expect from us \nA comprehensive benefits package that includes an annual bonus plan, private medical insurance, life insurance, and a contributory pension scheme \nEquity, so that our team can share in the long-term success of Riverlane \n28 days annual leave, plus bank holidays and enhanced family leave \nA diverse work environment that brings together experts in many fields (including software and hardware development, quantum information theory, physics and maths) and over 20 different nationalities \nA learning environment that encourages individual, team and company growth and development, including a regular programme of learning events and training and conference budgets \n\nHow to apply \nPlease upload a CV and covering letter by clicking 'Apply'. Your covering letter should explain why you are applying for the job and what skills and experience you can bring to the role. \nWe review CVs as we receive them and interview as soon as we have applications that look like a good match.
