The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products, Infleqtion enables “quantum everywhere” through our ecosystem of devices and platforms. Our mission is to commercialise atom-based quantum products that provide orders of magnitude improvements in performance and computing applications.\nLocation\nInfleqtion has offices in the USA, United Kingdom and Australia. This is a full-time position in our Kidlington, Oxford office. Our flexible working policy enables all full-time employees to work up to 2 days a week from home as work permits.\nPosition Summary\nAs part of our strategy for growth in the UK, we are expanding our Physics Department and recruiting an experimental AMO Physicist for inertial sensing applications. In this role, you will actively contribute to ongoing research projects and assist in the exploration of new concepts and approaches for future products. This will cover either our continuous beam atom inertial sensor for navigation applications or our Bose Einstein Condensate platform for gravimetry applications, or both. Working closely with a team of physicists and engineers, you will play a vital role in the collaborative efforts of the team.\nJob Responsibilities\nProject Support\nTranslate product requirements into atomic system designs. \nExecute modelling, simulation, and analytical calculations to design systems required to meet product performance. \nDesign and execute testing and verification plans. \nIntegrate complex opto-mechanical systems, electronics, and software into quantum devices. \nPerform technical tasks needed for the success of the project from equipment setup to system demonstration. \nIdentify materials and components to meet project requirements. \nDocument project progress and identify, track and resolve any project issues. \nTeam Collaboration\nWork collaboratively with team members against tight deadlines. \nCollaborate with fellow physicists, engineers, and technicians to perform technical laboratory tasks needed for the success of the project, from equipment setup to system demonstration. \nAbility to work with multi-disciplinary teams to develop commercial and non-commercial products and/or draft new quantum-led projects. \nCapable of handling changing circumstances and ambiguity. \nStakeholder Engagement\nContribute to external reports and publications, author/co-author papers, proposals, presentations and reports, give invited talks, attend project workshops and conferences. \nRequirements\nWhat you will bring to the team:\nTechnical Knowledge\nPhD in experimental atomic, molecular, and optical (AMO) physics. \nKnowledge of atom interferometry for inertial sensing applications \nExperience working with laser systems; optical design, alignment, and control \nWorking knowledge of control systems and signal processing \nProficiency in a programming language (e.g. Python) \nEntrepreneurial drive, intellectual agility and personal eagerness to develop with the needs of the business. \nProficient in MS Office \nGood verbal and written communication skills, able to effectively share information with technical and non-technical staff, both in writing and orally \nGood collaboration skills, able to work in a team environment where engagement and participation are an expected part of successful job performance. \nExperience\nExperimental and theoretical familiarity with the interactions of light with atoms, ions, or molecules \nProven track record of integrating complex hardware and software into systems \nUnderstanding of ultra-high vacuum \nFamiliarity with mechanical, optical, and electronic design packages (e.g. Solidworks, Zemax, Altium) \nPrior experience in project management is a plus. \nUnderstanding of Health, Safety, and Environment (HSE) practices and modeling workplace safety culture. \nWorking conditions and Physical Requirements\nWork will normally be performed in an office and laboratory environment and around technical equipment including computers and lasers. Able to sit, stand, bend, lift and carry up to 15 kg without assistance. Able to efficiently use automated office equipment such as laptops, copiers, and printers; able to effectively engage in communications (via phone, computer, or in-person). Any required Personal Protective Equipment will be provided and must be properly used in accordance with company requirements.\nBenefits\nIn addition to your base compensation, we offer a generous Total Rewards program which includes:\nCompetitive salary \nBonus scheme\nUnlimited PTO subject to fair usage\nGenerous company 10% pension contribution regardless of employee contribution \nCycle to work scheme \nTax efficient technology schemes \nIncentive Stock Option Plan \nBUPA Private Healthcare Insurance once probationary period is successfully completed\nLife Assurance (4 x salary) \nTravel\nUp to 10% travel may be required.\nEqual Opportunity\nRegardless of your interest in the quantum industry, you can take pride in the fact that Infleqtion is building an ecosystem of quantum technologies and commercial products, driving the industry towards the future. Studies reveal that while men apply for jobs when they meet an average of 60% of the requirements, women and other groups tend to apply only when they meet all the criteria.
