Research Engineer, AI/LLM/HPC Network

We need to output only HTML fragment, no html/body tags, no markdown fences. Use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We need to include sections only when posting has real specific content. We have content: Responsibilities (list). Qualifications (minimum and preferred). About TikTok (maybe "About the role"? Actually "About TikTok" is about company; could be "About the role"? The instruction: use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. So we need to map content to these headings. We have responsibilities list. We have qualifications (minimum and preferred). We have "About TikTok" which could be "About the role"? But "About the role" is more about the job description; we have a paragraph about the networking team and what they do. That could be "About the role". Also we have "Why Join Us" etc which could be "Benefits"? Actually benefits are listed later: medical, dental, vision, 401k, etc. Also we have Pay: compensation range. Schedule not given. Skills? Not explicit but could infer from qualifications. But we should only include sections with real specific content. We have Pay (compensation range). We have Benefits (list). We have Responsibilities. We have Qualifications (minimum and preferred). We have About the role (the networking team description). We might also have Skills? Not separate; qualifications cover skills. Could omit Skills if no explicit list. We must not repeat job title as heading. No Job ID etc. Remove boilerplate: Diversity & Inclusion, TikTok Accommodation, Job Information (some parts we need to keep pay and benefits). Also remove EEO etc. Also remove application instructions. Also remove "For Los Angeles County (unincorporated) Candidates:" etc (that's legal). Remove that. We need to preserve all substantive information: responsibilities list, qualifications min/pref, about TikTok (mission etc), why join us (maybe part of About the role?), benefits list, pay range. We need to format:

About the role

then

... (the networking team paragraph). Then

Responsibilities

• ... each bullet. Then

  Qualifications

  maybe we need to split into Minimum and Preferred? Could use

  Minimum Qualifications

  but instruction only allows those specific headings; but we could still use

  Qualifications

  and inside have subheadings? Not allowed? The instruction says use

  for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It doesn't forbid other headings, but better to stick to those. We could put both min and pref under Qualifications heading, using

  or

  . We'll list them. We also have "About TikTok" and "Why Join Us" maybe could be part of About the role? Could create a section "About the role" containing both the team description and why join us? But "Why Join Us" is more about benefits/culture; but we already have Benefits and maybe we could put culture under About the role. However we have a separate Benefits section for tangible benefits. The "Why Join Us" is more about mission and values; could be part of About the role or maybe we could omit as it's somewhat fluff but still substantive. The instruction: preserve ALL substantive information; do not invent or summarize away detail. So we should keep it. Where to place? Could be under About the role as a paragraph after the team description. Thus About the role section will contain: The Networking team brings together ... (first paragraph). Then "Why Join Us" paragraph(s). We'll combine. Now Benefits: list of medical, dental, vision, 401k, paid parental leave, short/long term disability, life insurance, wellbeing benefits, 10 paid holidays, 10 paid sick days, 17 days Paid Personal Time. Also note that benefits may vary etc; we should keep that sentence? It's substantive but maybe boilerplate? It's describing variability; we can keep as a note. Pay: base salary range $207,480 - $368,220 annually. Also note compensation may vary etc; also mention discretionary bonuses/incentives, RSU. We'll include that. Schedule: not present, so omit. Skills: not explicit; we could omit. Requirements: not separate; qualifications cover. Thus output:

  About the role

  ...

  Why Join Us ...

  Responsibilities

  Benefits may vary depending on the nature of employment and the country work location. Employees have day one access to ... The Company reserves the right to modify or change these benefits programs at any time, with or without notice.

  Pay

  The base salary range for this position in the selected city is $207,480 - $368,220 annually. Compensation may vary outside of this range depending on a number of factors, including a candidate’s qualifications, skills, competencies and experience, and location. Base pay is one part of the Total Package that is provided to compensate and recognize employees for their work, and this role may be eligible for additional discretionary bonuses/incentives, and restricted stock units.

  We must not include any markdown fences. Just raw HTML. Check for any leftover boilerplate: Diversity & Inclusion, TikTok Accommodation, Job Information (we used parts). Remove "For Los Angeles County (unincorporated) Candidates:" etc. Also remove "TikTok is the leading destination for short-form mobile video." That's part of About TikTok; we might incorporate that into About the role? Actually we have a paragraph "About TikTok TikTok is the leading destination for short-form mobile video. At TikTok, our mission is to inspire creativity and bring joy." That's substantive about company; we could include in About the role as well. But we already have About the role with team description and Why Join Us. Could also include that mission statement. Let's incorporate: After the team description, we can add a sentence about TikTok being leading destination etc. Or we could create a separate "About TikTok" section but not in allowed headings; we could fold into About the role. Thus About the role will contain: The Networking team brings together ... (first paragraph). Then "About TikTok: TikTok is the leading destination for short-form mobile video. At TikTok, our mission is to inspire creativity and bring joy." Then "Why Join Us ..." etc. We must ensure we don't repeat sentences unnecessarily but preserve all. Let's extract exact text: From posting: "Responsibilities The Networking team brings together innovative ideas and technologies from network architecture, software defined networking (SDN), network virtualization, switch software and hardware co-design, and high-speed networking, to create hyperscale data-center networking solutions that power several of the most popular apps of the world such as Douyin and TikTok which serve hundreds of millions of users around the globe.

Then Qualifications etc. Then "About TikTok TikTok is the leading destination for short-form mobile video. At TikTok, our mission is to inspire creativity and bring joy. TikTok's global headquarters are in Los Angeles and Singapore, and we also have offices in New York City, London, Dublin, Paris, Berlin, Dubai, Jakarta, Seoul, and Tokyo." Then "Why Join Us Inspiring creativity is at the core of TikTok's mission.

(remove) Then "Job Information 【For Pay Transparency】Compensation Description (Annually) The base salary range for this position in the selected city is $207480 - $368220 annually. Compensation may vary outside of this range depending on a number of factors, including a candidate’s qualifications, skills, competencies and experience, and location.

Benefits may vary depending on the nature of employment and the country work location.

Interacting and occasionally having unsupervised contact with internal/external clients and/or colleagues; 2. Appropriately handling and managing confidential information including proprietary and trade secret information and access to information technology systems; and 3. Exercising sound judgment." We need to keep the compensation and benefits sentences, but remove the LA County legal part. Thus Benefits section will include the list and the sentence about benefits may vary etc and day one access etc and the Company reserves right. Pay section includes base salary range and compensation may vary etc and base pay part. Now we need to ensure we don't include any duplicated lines. The responsibilities heading appears twice in the text; we will output only once. Now produce HTML. Let's craft:
