Top Tech Jobs & Startup Jobs

Support coordination and execution of safety and project-management activities for accelerator upgrade, consolidation, maintenance, dismantling and commissioning. Prepare and maintain safety documentation and Safety Files, track actions and reporting, participate in meetings and site visits, contribute to risk assessments (chemical, nano, electrical, radiological), support operation readiness and on-site contractor coordination, and implement and monitor safety controls for underground and surface installations.

Support and modernise CERN finance and procurement reporting: extract, transform, model and visualise data; develop and maintain reporting/semantic models and ETL pipelines; perform data profiling, quality checks, migration validation, third-level support, and collaborate with business users and engineers in an Agile environment.

Maintain and develop beam instrumentation software, modernise real-time and embedded systems, and design, deploy, and optimise AI/ML solutions for diagnostics, anomaly detection, and system optimisation. Collaborate with multidisciplinary teams, share knowledge, and mentor junior staff.

Hands-on studentship supporting mechanical engineering projects (design, manufacturing, assembly, testing) under close supervision. Assist engineers and technicians, collaborate within international multidisciplinary teams, and develop practical skills during a 4–12 month onsite placement.

Hands-on studentship supporting electrical/electronics projects: assist engineers and technicians with installation, testing, maintenance, and day-to-day technical tasks under close supervision while collaborating within a multidisciplinary team.

Hands-on studentship supporting projects in software development, computing infrastructure, or robotics. Learn from engineers and scientists, assist in day-to-day technical tasks under close supervision, and collaborate within an international multidisciplinary team.

Develop and validate quasi-geoid and gravity-field models for the FCC and Switzerland. Propose equipotential modelling inside tunnels, run field observation campaigns (gravity, GNSS, leveling, astro-geodetic), build gravity-modelling software, and supervise team activities to support sub-millimetric alignment of accelerator components and detectors.

Operate, modernize and automate CERN's PostgreSQL and MySQL platforms focusing on high availability, resilience, failover, performance, backups and disaster recovery. Design and run HA PostgreSQL infrastructures, build automation (provisioning, failover, monitoring), support application teams, troubleshoot production incidents, and provide mentorship and documentation for database services.

Design, integrate and operate test and measurement systems for superconducting magnets. Develop and maintain C++, Python and LabVIEW control and DAQ software, integrate electronics, timing, interlocks and protection on Linux/real-time platforms, operate cryogenic and high-voltage tests, troubleshoot measurement chains, collaborate with multidisciplinary teams, and follow software engineering best practices.

Ensure CMS Equipment Management Database accurately reflects installations and removals during LS3. Maintain and enhance the database and web applications, develop dashboards and visualization tools, support field inventory activities, ensure data quality and traceability, and collaborate with CERN asset management services.
