What the posting says

Cambridge, UK | Full-time or Part-time | Permanent (or Temporary) | Hybrid  Salary: £64,000 to £76,000, DOE   The salary range for this role is broad, as we are able to consider varying levels of experience.  Any offer made will carefully take into account level of experience (including relevant industry experience), transferable relevant skills and previous relevant achievements.   About us  Riverlane’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.   Having 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.     About the role:  We’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).  This 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.    What you will do (specific responsibilities) :  <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Design, write and maintain Python tests (using pytest) across our QEC software stack, including Deltakit and the compiler front end </li> </ul> <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="2" data-aria-level="1">Test features from the customer’s point of view, and check that your tests reflect how users will actually work with the product </li> </ul> <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="3" data-aria-level="1">Spot where functionality could be clearer or easier to use, and propose improvements </li> </ul> <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="4" data-aria-level="1">Share findings with engineering and product teams, and follow your suggestions through to changes in the product </li> </ul> <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="5" data-aria-level="1">Work closely with developers to understand new features and plan how they should be tested </li> </ul>   What we need: <ul> <li data-leveltext="" data-font="Symbol" data-listid="3" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="6" data-aria-level="1">Knowledge of quantum computation and core concepts such as quantum circuits.
