Since then, we’ve grown from 3 to 700+ people, gained unicorn status, raised ~£140M over three funding rounds, turned profitable, insured millions of drivers and lent millions in car loans.\nBut we’re only just getting started. Our goal is to become one of the largest financial services providers in the world. Over the next 10 years we’ll grow exponentially, not only by scaling our existing products, but also by building new ones.\nTo achieve our goals we need incredibly ambitious, commercially driven people who never settle for ‘good enough’. Marshmallowers are hungry for autonomy and ownership, and would rather improve than coast. Everyone raises standards and has an impact, with a focus on collective success over self-interest.\nWe’ve created an environment where curious, tenacious people win and grow together. If that sounds motivating, this could be the place for you.\nLondon (hybrid, 3 days in office)\nWe are not able to offer visa sponsorship for this position.\nAbout the team\nMarshmallow's pricing team applies quantitative methods to real insurance problems. In this role, you'll learn how pricing decisions work in practice and turn data into meaningful outcomes. You'll work closely with a senior pricing team member, bringing your quantitative background into an industry setting. The aim is for you to develop the practical judgement and independence to take on - and eventually lead - increasingly substantial work.\nWhat you'll be doing\nWorking closely with pricing colleagues on scoped analytical and data-driven projects, taking on more responsibility as your experience develops.\n\nApplying mathematical, statistical and machine learning techniques to practical pricing questions, connecting your analysis to the decision it needs to inform.\n\nExplaining your findings clearly, keeping colleagues from different areas of the business updated on progress and following up on agreed actions.\n\nUsing feedback to improve your work and build your understanding of data science methods, coding best practice and the commercial context of insurance pricing.\n\nWho you are\nYou want to learn, seek feedback and build towards working independently.\n\nYou communicate your rationale and findings clearly, and keep colleagues informed about your progress.\n\nYou follow through on agreed actions and take ownership of your work.\n\nWhat you’ll bring\nA strong academic record and a research master's or PhD in a quantitative field, such as mathematics, physics or econometrics.\n\nExperience applying quantitative methods or machine learning to a practical problem through your studies, research, a personal project or work.\n\nIndustry experience is preferred - a placement, internship or experience whilst studying, or in between research masters / PhD.\n\nThe ability to explain how your approach fits the problem, rather than relying on theory alone.\n\nPerks of the job\nBonus scheme designed to reward high performance\n\nPrivate medical insurance with Vitality, mental health support with Oliva\n\nPersonal learning budget and 2 dedicated L&D days a year\n\nMonthly flexible benefits budget to spend as you choose\n\n25 days holiday plus bank holidays\n\n4 weeks Work From Anywhere per year\n\nOur process\nInitial call with a member from our Talent Team (30 mins)\n\nCombined Past Experience & Technical interview (90 mins)\n\nOnsite Culture interviews (90 mins)\n\nDiversity of thought\nWe know the best ideas come from having different perspectives in the room - and we're committed to hiring fairly, regardless of background, identity or experience.
