We believe small, highly skilled teams outperform large, fragmented organizations, and we are intentional about staying focused on impact, quality, and speed.\nWe operate with a flat org structure and value in-person collaboration, which helps ideas move faster, decisions stay grounded, and teams take full ownership of what they build.\nOur values\nCare We care deeply about our customers, our teammates, and the quality and reliability of what we ship.\n\nBias for Action We move fast, test in the real world, and iterate quickly rather than over-optimizing in theory.\n\nOwnership We take responsibility end to end, from identifying problems to delivering outcomes and learning from results.\n\nWhat will you be doing?\nBuilding polished, high-performance user interfaces using React and Typescript, with a strong focus on usability, speed, and design quality\n\nOwning features end to end - from the React frontend through the Go backend, APIs, and data layer\n\nWorking across the stack on our distributed system using Go, DynamoDB, SQS, Redshift, and Lambdas\n\nShaping and building the next version of the Prelude API, which we strive to be industry-leading in terms of usability, performance, and functionality\n\nDesigning and building internal tools and dashboards that improve developer and team efficiency\n\nHelping deploy and scale our fraud prevention model to hundreds of large customers\n\nInteracting with clients on a daily basis to assist them and build features around their needs\n\nParticipating in on-call rotations to guarantee the stability and reliability of our services\n\nWhat are we looking for?\nStrong experience building frontends with modern frameworks : React is ideal, Vue or similar also welcome\n\nSolid backend skills in Go or TypeScript, with the ability to design and build reliable APIs and services\n\nYears of experience working across the full stack, from UI to infrastructure\n\nA preference for simplicity vs complexity, with intuition for what will scale effectively\n\nA keen eye for product and UX - you care about what the user sees and experiences, not just what the code does\n\nA product-led mindset, keen to code for the output and the impact\n\nFluent/professional English given our international team\n\nAny experience with Rust, gRPC, or AWS serverless (Lambda, DynamoDB, SQS) is a plus\n\nWhat can we offer you?\nCompetitive compensation package with BSPCEs\n\n3 days in-office in central Paris, with 2 days WFH; and 4 weeks of remote work per year\n\n100% travel to the office subsidised\n\nHealth insurance via Alan\n\nUrban Sports Club gym membership\n\nWe will provide you with the gear you need for your role (a laptop and a phone, for on-call rotations)\n\nSwile meal vouchers\n\nFree snacks and drinks in the office\n\nAn annual offsite in a great location (last one was at La Pradet!)\n\nThe opportunity to build something from 0-1, and make an impact every day\n\nInterview process\nMeet a member of the Talent team\n\nTechnical assessment\n\nIn-person interview (system design, coding)\n\nFinal meeting with CEO\n\nWe don't expect you to ace all these stages, we will evaluate your creativity and how you approach difficult problems.
