About CorintisCorintis is a Lausanne-based deep-tech startup developing advanced semiconductor cooling technologies to overcome one of the biggest bottlenecks in modern computing: heat dissipation.As compute demand grows (AI, HPC, cloud), extracting heat efficiently becomes critical. Corintis enables this through microfluidic cooling embedded directly inside chips, achieving significantly higher efficiency than conventional approaches.We are an EPFL spin-off, backed by leading investors, and ranked among the Top 100 Swiss Startups.About The RoleCorintis is seeking a Full-Stack Engineer to help teams get more value out of the applications they build using AI coding tools.Many internal tools and prototypes are quickly developed but remain hard to use, unreliable, or not well integrated into workflows. Your role will be to improve, connect, and stabilize these applications so they can be effectively used within the company.You will work across the stack to refine applications, debug issues, and integrate them into existing systems and processes.What Youll Work OnYou will support internal applications by:Improving and stabilizing AI-generated toolsDebugging issues across frontend and backendIntegrating apps with internal systems (APIs, data pipelines, simulation tools)Enhancing usability and workflows for internal usersSetting up simple deployment and access within the companyConnecting different tools to work together seamlesslySupporting lightweight desktop or web-based internal appsKey ResponsibilitiesMaintain and improve internal full-stack applicationsDebug and resolve issues across the stackIntegrate applications into existing infrastructure and workflowsRefactor code for clarity and maintainabilityHelp teams make their tools usable by others internallySupport basic deployment and distribution (internal use)Collaborate closely with engineers and non-technical usersQualificationsRequiredMasters in Software Engineering or related field24 years of experience in full-stack developmentExperience with modern web stacks (React, Node.js, Python (Fast API), Spring Boot or similar)Ability to debug and improve existing codebasesUnderstanding of APIs and system integrationPragmatic mindset and ability to work on imperfect codeNice to HaveFamiliarity with AI coding tools (Copilot, ChatGPT, etc.)Experience with Docker or simple deployment setupsBasic understanding of security and access controlInterest in engineering tools or simulation workflowsWhy This Role MattersThis role helps ensure that internally built tools are not just functional, but actually usable and valuable across the company.You will play a key role in:Connecting tools and workflowsImproving reliability of internal applicationsEnabling teams to move faster with AI-assisted developmentWorking at CorintisCorintis offers a collaborative and international environment, bringing together engineers across disciplines to solve complex technical challenges.We are based at EPFL Innovation Park in Lausanne, minutes away from Lake Geneva, and closely connected to one of Europes leading research ecosystems.
