Thermo Fisher Scientific's Materials and Structural Analysis Semiconductor R&D; organization brings together around 400 engineers developing electron microscopy solutions and applications. Our global teams in Eindhoven, Brno, Hillsboro, Hyderabad, and Bordeaux combine expertise in hardware, software, and scientific applications to help customers make the world cleaner, healthier, and safer.
Within this organization, the Cortex value stream develops software for semiconductor data workflows, including tools to organize, explore, and visualize microscopy data. We're looking for a Backend Technical Lead to own Cortex backend architecture, services, and data integration, and help the team deliver secure, scalable, and reliable software.
You'll provide hands-on technical leadership for Cortex backend services and integrations. You'll guide design decisions, API contracts, and service development across the Cortex ecosystem, working closely with the Frontend Technical Lead, DevOps, architects, product owners, and partner teams.
Your ownership will span Cortex backend services, the Cortex Semi Gateway, Process Explorer and File & Recipe backends, Central Cortex, and Contributor backend integration. You'll help ensure that data and services work reliably across system boundaries, and that backend solutions are ready to operate and evolve in production.
Own and guide the architecture and technical direction of Cortex backend services.
Lead design and development for the Cortex Semi Gateway, Process Explorer backend, File & Recipe backend, and Central Cortex capabilities.
Design and develop REST APIs and microservices using C#, .NET, and ASP.NET Core.
Guide data integration and persistence across SQL, PostgreSQL, MongoDB, and other appropriate data stores.
Lead integrations with Athena and DAP, and support backend integration for Contributor applications.
Work closely with the Frontend Technical Lead on API design, data contracts, and end-to-end user workflows.




Partner with DevOps to build, deploy, and operate containerized services using Docker and Kubernetes.
Promote automated testing, code quality, maintainability, and reliable CI/CD practices.
Improve service scalability, performance, resilience, and observability as product needs evolve.
Participate in architecture and design reviews, making pragmatic decisions that balance product needs, technical quality, and delivery.
Regularly reflect with the team on how to improve collaboration, service quality, and delivery.
You'll work with a distributed Agile Scrum team alongside colleagues in Bordeaux, Hillsboro, the Netherlands, and the Czech Republic. Bachelor's or master's degree in computer science, software engineering, computer engineering, or a related technical field, or equivalent practical experience.
