Senior Machine Learning Engineer, Recommendations - USDS
for section headings (About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)
2. Use - for lists of duties/requirements/benefits, and
for prose
3. Do NOT repeat the job title as a heading (page already shows it)
4. Do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it
5. Preserve ALL substantive information; do NOT invent or summarize away detail
6. Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions
7. Include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text
8. Never create Pay/Schedule/Benefits sections unless the posting actually states them
9. Prefer a few substantive sections over many thin ones
10. Output ONLY the HTML fragment — no /, no markdown code fences
Let me analyze the input:
The posting has:
- "Responsibilities" section with "About the Team" and "What you will do:" with bullet points
- "Qualifications" section with "Minimum Qualifications" and "Preferred Qualifications" bullet points
- "About USDS" section describing the company
- "Why Join Us" section
- "Diversity & Inclusion" section
- "USDS Reasonable Accommodation" section
- "Job Information" with pay transparency details (salary range, benefits, etc.)
I need to structure this into appropriate sections. The rules say to use specific heading names: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule.
Looking at the content:
- "About the Team" could be "About the role" or "About the team"
- "What you will do" is clearly Responsibilities
- "Minimum Qualifications" and "Preferred Qualifications" are Qualifications/Requirements
- "About USDS" is company info
- "Why Join Us" is company culture
- "Diversity & Inclusion" is DEI
- "USDS Reasonable Accommodation" is legal/accommodation
- "Job Information" has Pay and Benefits details
The rules say: "include a section ONLY when the posting has real, specific content for it". The posting has real content for Pay and Benefits (salary range, benefits list). So I should include Pay and Benefits sections.
Also, "About USDS", "Why Join Us", "Diversity & Inclusion", "USDS Reasonable Accommodation" are boilerplate-ish but they are specific to this posting. However, the rules say "Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate". The Diversity & Inclusion and Reasonable Accommodation might be considered EEO/legal boilerplate. But they are part of the posting. The instruction says "Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions." So I should remove EEO/equal-opportunity boilerplate. The Diversity & Inclusion and Reasonable Accommodation are EEO-related. However, they are specific to USDS. But they are still boilerplate. I think I should remove them as they are standard legal boilerplate.
The "About USDS" and "Why Join Us" are company description and culture. They might be considered "About the role" or "About the company". The rules don't have a specific heading for "About the company". The allowed headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. I could put "About USDS" and "Why Join Us" under "About the role" or maybe create a section "About the team" but the rules say use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It says "e.g." so maybe other headings are allowed? But it says "use for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)". This suggests those are the expected headings. However, the posting has "About the Team" which is similar to "About the role". I'll map "About the Team" to "About the role". "Why Join Us" could be part of "About the role" or maybe "Benefits"? But Benefits is for employee benefits. "Why Join Us" is more culture. I could include it as a separate section but the rules say prefer a few substantive sections over many thin ones. I'll combine "About the Team" and "Why Join Us" into "About the role".
The "Job Information" contains Pay and Benefits details. So I'll create Pay and Benefits sections.
The "Qualifications" section has Minimum and Preferred. I'll put under "Qualifications" heading.
The "Responsibilities" section has "What you will do" bullet points. I'll put under "Responsibilities".
Now, the "About USDS" is a paragraph about the joint venture. That could be part of "About the role" or a separate "About the company". Since the rules don't have "About the company", I'll include it in "About the role" as a paragraph.
The "Diversity & Inclusion" and "USDS Reasonable Accommodation" are EEO boilerplate, so remove.
The "Job Information" also has a note about Los Angeles County Fair Chance Ordinance. That's legal boilerplate, remove.
Now, the pay transparency section: "Compensation Description (Annually) The base salary range for this position in the selected city is $187040 - $359720 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."
Benefits: "Benefits may vary depending on the nature of employment and the country work location. Employees have day one access to medical, dental, and vision insurance, a 401(k) savings plan with company match, paid parental leave, short-term and long-term disability coverage, life insurance, wellbeing benefits, among others. Employees also receive 10 paid holidays per year, 10 paid sick days per year and 17 days of Paid Personal Time (prorated upon hire with increasing accruals by tenure). The Company reserves the right to modify or change these benefits programs at any time, with or without notice."
That's substantive, so include Pay and Benefits sections.
Now, the "Qualifications" section: Minimum Qualifications bullet points, Preferred Qualifications bullet points. I'll list them under Qualifications heading, maybe with subheadings? But the rules say use for section headings, and - for lists. I could use
for Minimum and Preferred? But the rules only mention for section headings. It doesn't forbid . But to keep simple, I'll just put them as separate lists under Qualifications with maybe a paragraph indicating Minimum and Preferred. Or I can use two with a preceding for each. I'll do:
Qualifications
Minimum Qualifications
- ...
Preferred Qualifications
- ...
That's fine.
Now, the "Responsibilities" section: "What you will do:" bullet points. I'll put under Responsibilities heading.
The "About the Team" is a paragraph. I'll put under "About the role" heading.
The "Why Join Us" is multiple paragraphs. I'll include them under "About the role" as well.
Now, the "Job Information" also includes "For Pay Transparency" heading. That's the Pay section.
Now, I need to output only HTML fragment.
Let me structure:
