Top Tech Jobs & Startup Jobs

Develop and maintain full-stack applications using Java, React, Spring Boot, Oracle, and BPMN to support CERN engineering and access-management processes. Collaborate with engineers and IT specialists to gather requirements, implement solutions, test and debug software, optimize performance, and participate in Agile development. The role requires strong collaboration in an international environment, English proficiency, willingness to learn French and CERN-specific processes, and adherence to graduate eligibility requirements.

Operate and maintain CERN’s EOS distributed storage services at exabyte scale. Troubleshoot and optimize software, hardware, and network layers; contribute to platform development, testing, deployment, automation, observability, reliability, and performance improvements. Collaborate with users, developers, service managers, and external partners supporting scientific computing and data management services.

Supports High-Luminosity LHC installation activities during LS3 by tracking worksite progress, updating schedules and 3D models, analyzing engineering changes, coordinating meetings, reporting issues, and supporting installation readiness reviews. The role requires field work in underground and radiation areas, stakeholder coordination, schedule control, and preparation of de-installation and installation procedures.

Develop and operate CERN collaboration and communication services, including email, group management, media, and Microsoft 365 integrations. Manage identity and group synchronization across Active Directory, Entra ID, and Exchange Online; improve provisioning, reliability, observability, scalability, and security. Contribute to software development, infrastructure automation, troubleshooting, and strategic media and conferencing projects. Serve as deputy email service manager and collaborate with infrastructure, security, and IT teams in a hybrid international environment.

Develop and maintain the Open Research Europe publishing platform based on Open Journal Systems. Responsibilities include PHP and Laravel development, plugin and integration testing, open-source contributions, Kubernetes/OpenShift deployment, CI/CD automation, infrastructure maintenance, performance testing, documentation, and operational support. The role is hybrid, includes possible standby and out-of-hours duties, and requires no more than two years of professional experience after graduation.

Develop system-level simulation models and digital ASICs for advanced particle-detector electronics. Responsibilities include architecture modelling, circuit implementation, verification, validation, performance optimization, technical documentation, multidisciplinary collaboration, and team supervision.

Design and validate a radiation-tolerant RISC-V microcontroller ASIC for CERN detector and accelerator systems. Responsibilities span requirements, SoC architecture, RTL and peripheral IP development, fault-tolerant design, verification, physical implementation, tapeout, and post-silicon testing. The role requires digital IC design experience, ASIC flow knowledge, embedded C development, Python scripting, and familiarity with RISC-V, CMOS radiation effects, and Linux/Unix.

Design, operate, troubleshoot, and optimize large-scale distributed storage services based on Ceph across CERN’s multi-datacenter infrastructure. Develop C++ improvements for Ceph, support block, object, and filesystem services, automate deployments, improve observability, respond to incidents, provide user support, and collaborate with international stakeholders.

Develop, integrate, and test FPGA gateware and embedded SoC firmware for high-speed beam-position monitoring systems. Implement data acquisition, real-time digital signal processing, and embedded processing algorithms. Validate systems in laboratory and accelerator environments, perform Python-based data analysis, support measurement campaigns, and collaborate with engineers, physicists, and technicians at CERN.

Operate PVD sputtering systems, including assembly, vacuum pumping, bakeout, deposition, and disassembly. Measure thin-film thickness and composition using X-ray fluorescence, validate NEG coating performance, and perform quality control. Prepare technical reports and procedures, and support tooling design, procurement, and assembly. The role involves vacuum technology, materials characterization, onsite work, radiation areas, underground installations, and occasional night, Sunday, and holiday interventions.
