Job Description

Lawrence Berkeley National Lab's ( ) Advanced Light Source ( ) Division has an opening for a Scientific Web Developer.
As part of the Photon Science Computing (PSC) group, the Computer Systems Engineer will help shape the strategy for control system user interfaces across the facility. This hands-on role includes designing, developing, maintaining, and supporting UI applications that control and monitor scientific instruments. The engineer will collaborate with scientists, engineers, and external partners to create robust, user-centered software solutions that expand experimental capabilities and boost operational efficiency.
The Advanced Light Source is a U.S. Department of Energy (DOE) Office of Science national scientific user facility that produces exceptionally bright soft and hard x-ray, ultraviolet, and infrared light. With a strong scientific reputation, expert staff, and advanced capabilities, the ALS attracts thousands of academic and industrial users each year in condensed matter and quantum materials, energy sciences, biosciences, earth and planetary sciences and more.
The ALS is one of five Berkeley Lab user facilities that serve 15,000 users annually. Co-located with the Molecular Foundry, NERSC supercomputing center, and Berkeley Lab's materials, chemical sciences, biosciences, and other divisions, it provides an ideal collaborative environment for innovative scientific discoveries.
The ALS is a global leader in soft x-ray science, and aims to maintain its leadership with ALS-U, a major project to upgrade the facility to a fourth-generation light source. This upgrade will position the facility among the brightest soft x-ray light sources in the world, offering capabilities that no other facility can provide.
You will:

• Design and develop browser-based user interfaces for scientific workflows and real-time data visualization from instruments.
• Create platforms for advanced data analysis and AI/ML-driven orchestration.
• Collaborate with ALS scientists to gather requirements and deliver tailored software solutions.
• Build and maintain scalable, sustainable frameworks supporting multiple UI configurations.
• Provide technical support, troubleshoot issues, and ensure smooth user experiences.
• Use modern practices for testing, deploying, and maintaining software systems.
• Write clear, user-focused documentation, including guidelines and tutorials.
• Work directly with beamline scientists to develop custom solutions.
• Contribute to open-source projects and collaborate with other scientific facilities.
• Present work to ALS staff, collaborators, and stakeholders as needed.
• Lead the implementation of web-based solutions, offering technical expertise.
• Develop backend services that integrate with authentication systems, user databases, and scientific tools.
• Define and maintain publicly shared code libraries for the scientific community.
• Champion accessibility and inclusive UX for diverse scientific users.

We are looking for:

• Bachelor's degree with a minimum of 8 years of related experience, or Master's degree with 6 years, or equivalent experience.
• At least 4 years of experience in web application development.
• Proficiency in front-end development, including experience with SPA frameworks such as React, Vue, or Angular.
• Experience with backend frameworks (e.g., Node.js, FastAPI, Django).
• Familiarity with modern software development practices: version control, build tools, issue tracking, and continuous integration (CI).
• Experience with containerization and deployment technologies (e.g., Docker, Kubernetes, Podman).
• Strong analytical, problem-solving, and organizational skills with excellent attention to detail.
• Effective team player with the ability to collaborate with scientists and external partners.
• Interest in supporting scientific research environments.
• Proficient in Python (minimum 1 year) and experienced with SQL databases.
• Ability to install and maintain server hardware, including lifting up to 20 lbs.

Desired skills/knowledge:

• Experience with control systems such as Bluesky, EPICS or similar.
• Skilled in scientific instrumentation and automating experimental workflows.
• Experience with real-time data streaming (e.g., websockets, Kafka) and visualization at instrument rates.
• Hands-on with DevOps for scientific apps (CI/CD to on-prem clusters; containers at beamlines).
• Experience integrating authentication and authorization protocols (e.g., OIDC, SAML).

Additional information:

• Application date: Priority consideration will be given to candidates who apply by November 18, 2025. Applications will be accepted until the job posting is removed.
