We need to output HTML fragment with sections: headings
for sections like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections where posting has real specific content. We need to parse the job posting. We have: - Overview: description about NCCS, team, role. Could be "About the role" or "Overview". We'll use "About the role" heading. - The Team: maybe part of About the role. - The Role: description of duties. - Major Duties/Responsibilities: list of duties. - Infrastructure as Code (IaC) & Tooling: more duties. - Internal Developer Platform & Enablement: duties. - Technical Leadership & Mentorship: duties. - Collaboration: duties. - What Sets This Role Apart: maybe a summary. - Basic Qualifications: qualifications. - Preferred Qualifications: qualifications. - Special Requirements: includes Visa sponsorship not available, Q Clearance, WSAP testing. - About ORNL: description of org, benefits. - Benefits: list of benefits. - Pay: not mentioned explicitly. No pay info. So we should NOT include Pay section. - Schedule: not mentioned. So no Schedule. We need to remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning, duplicated lines, application instructions. Also remove "This position will remain open..." etc. Also remove "We accept Word..." etc. Also remove "ORNL is an equal opportunity employer..." etc. Also remove "UT-Battelle is an E-Verify employer." Also remove "Special Requirements" maybe keep visa sponsorship and clearance as part of Requirements? The instruction: "Do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it." So we can include Requisition Id maybe as a short p. We need to preserve all substantive information; do not invent or summarize away detail. We need to use
- for any list of duties/requirements/benefits, and
for prose. We need to output only HTML fragment, no /, no markdown fences. Thus produce something like:
About the role
Requisition Id 17094 ... overview ...
But we need to incorporate overview text: "The National Center for Computational Sciences (NCCS) at Oak Ridge National Lab (ORNL), which hosts several of the world’s most powerful computer systems, is seeking highly qualified individuals to play a key role in improving the security, performance, and reliability of the NCCS computing infrastructure which supports multiple highly ranked Top500 Supercomputers, including the world’s first exaflop system, Frontier. The Team The HPC Platforms design, manage, and operate Kubernetes clusters that support our supercomputing center’s mission. Our primary platform is the OLCF Slate Service, a container orchestration platform built on Rancher Kubernetes Engine 2 (RKE2). Slate hosts critical operational services and user-managed persistent applications that are deployed alongside and integrated with OLCF supercomputing systems and other OLCF-managed HPC clusters." We can combine into a paragraph. ThenResponsibilities
with a- listing duties. Need to capture all duties from sections: Major Duties/Responsibilities, Infrastructure as Code & Tooling, Internal Developer Platform & Enablement, Technical Leadership & Mentorship, Collaboration, What Sets This Role Apart (maybe as bullet). Ensure we don't lose any detail.
Let's extract duties:
From "Major Duties/Responsibilities":
- Platform Architecture & Implementation
- Lead the architecture, design, implementation, and lifecycle management of on-premises Kubernetes (RKE2) clusters.
- Evaluate, select, integrate, and standardize core platform components for networking, CI/CD, operating-system management, service mesh, and Kubernetes operators.
- Observability services are owned by a dedicated SRE sub-team, this role will ensure platform components integrate effectively with those services.
- Build and maintain test environments to evaluate candidate technologies for performance, functionality, operational reliability, and maintainability, particularly where integration with on-premises hardware and operating-system requirements is critical.
- Lead cluster upgrade strategy and execution, security hardening, scalability planning, and integration with monitoring and observability services.
- Infrastructure as Code (IaC) & Tooling
- Develop and maintain infrastructure, configuration, and deployment automation using technologies such as Argo CD and GitOps workflows, Puppet, Go, Python, Bash, and GitLab CI.
- Establish and promote reusable automation patterns, configuration standards, and engineering practices for operating Kubernetes clusters at scale.
- Support adoption and effective use of internally developed Kubernetes operators and serve as a secondary maintainer for designated controllers.
- Internal Developer Platform & Enablement
- Collaborate on the design and delivery of a next-generation internal developer platform, informed by capabilities offered by tools such as Backstage and AWS Proton, to improve developer productivity, platform consistency, and security.
- Partner with the cybersecurity team to define secure container-image baselines and automate image and golden base image workflows.
- Engage with development teams to understand platform needs and tailor the cluster experience to meet evolving requirements.
- Technical Leadership & Mentorship
- Provide architectural guidance, code reviews, and pair programming support to a team of 8-12 engineers.
- Mentor engineers in Kubernetes, platform engineering, automation, and operational best practices.
- Contribute to onboarding, team documentation, and process improvement initiatives.
- Serve as a primary technical resource for Kubernetes platform architecture, operations, and engineering practices across the organization.
- Collaboration
- Partner with cybersecurity, SRE, and development teams to ensure the platform meets security, compliance, reliability, and usability requirements.
- Lead or contribute to cross-functional initiatives involving platform enhancements, cluster lifecycle automation, and service integration.
- Represent the HPC Platforms team in engagements with vendors and internal and external collaborators and partners.
- What Sets This Role Apart
- Provide hands-on technical leadership for the full lifecycle of on-premises Kubernetes infrastructure, from operating-system and hardware integration through cluster services and deployment automation.
- Shape a platform centric engineering approach that balances security, developer experience, reliability, and operational scalability.
- Strong mentorship and team enablement focus; guiding engineers while staying hands-on with operations, architecture, and implementation.
We can combine these into a single list under Responsibilities.
Now Requirements/Qualifications:
Basic Qualifications:
- BS degree in computer science or related field and a minimum of 8 years of platforms engineering experience.
- At least 5 years of Kubernetes experience.
- An equivalent combination of education and experience may be considered.

Special Requirements:
- Visa sponsorship: Visa sponsorship is not available for this position.
- Security, Credentialing, and Eligibility Requirements: Q Clearance: This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.
We could include these under a "Requirements" section, maybe separate Basic and Preferred as subheadings? But instruction: use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we can have a heading "Qualifications" and include both basic and preferred as lists. Or we could have "Requirements" for basic and "Preferred Qualifications" as separate? But they said prefer a few substantive sections over many thin ones. So we can combine basic and preferred under "Qualifications" with two sub-lists maybe using
- with headings inside? But we cannot add extra headings besides
. We could embed a
stating "Basic Qualifications:" then a
- . Then another
"Preferred Qualifications:" then a
- . That's okay.
Similarly, we could have a "Skills" section maybe not needed; we can incorporate skills into Qualifications.
Benefits: The posting lists benefits under About ORNL: "ORNL offers competitive pay and benefits programs... The laboratory provides a range of employee benefits, including medical and retirement plans and flexible work hours, to support the well-being of you and your family. Employee amenities such as on-site fitness, banking, and cafeteria facilities are also available for added convenience. Other benefits include the following: Prescription Drug Plan, Dental Plan, Vision Plan, 401(k) Retirement Plan, Contributory Pension Plan, Life Insurance, Disability Benefits, Generous Vacation and Holidays, Parental Leave, Legal Insurance with Identity Theft Protection, Employee Assistance Plan, Flexible Spending Accounts, Health Savings Accounts, Wellness Programs, Educational Assistance, Relocation Assistance, and Employee Discounts."
We should include Benefits section with a
- of those benefits.
We should not include Pay or Schedule.
We need to remove boilerplate: "This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired." etc. Also "We accept Word (.doc, .docx), Adobe (unsecured .pdf), Rich Text Format (.rtf), and HTML (.htm, .html) up to 5MB in size." etc. Also "If you have trouble applying for a position, please email ORNLRecruiting@ornl.gov." Also "ORNL is an equal opportunity employer..." etc. Also "UT-Battelle is an E-Verify employer." Also "About ORNL" description maybe we can keep some but not the boilerplate. The About ORNL paragraph includes mission statement etc. That's substantive? It's about ORNL's mission, could be considered part of About the role? Might be okay to keep as part of About the role or maybe a separate "About the organization". But we only have headings list; we could include "About the role" and incorporate ORNL description there. However we need to preserve all substantive information; the ORNL description about mission, 80-year legacy, 7000 employees, etc is substantive. We could include it in About the role paragraph.
Thus About the role paragraph will include overview, team, role, and ORNL description.
Now we need to ensure we don't include duplicated lines. Let's craft.
