Senior Software Engineer, Design in Test (SDET)
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 (the 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 job posting:
- Job title: "Senior Software Test Engineer" (but also mentions "Software Development Engineer in Test (SDET)" - I should not repeat the job title as a heading)
- About Us section: describes BlackSky
- About the role: describes the SDET role
- Responsibilities: listed as bullet points
- Required Qualifications: listed
- Preferred Qualifications: listed
- Life at BlackSky (Benefits): listed
- Pay: "The anticipated salary range for candidates in Seattle, WA is $145,000-$165,000 per year."
- Location: "The preferred location is Tukwila, WA with the ability to work in the Tukwila office 1-2 days a week but we may be open to strong remote candidates."
- US citizenship requirement due to ITAR
- EEO/legal boilerplate at the end (should be removed)
I need to structure this into sections. The posting has:
- About the role (the description of the SDET role)
- Responsibilities
- Required Qualifications
- Preferred Qualifications
- Benefits (Life at BlackSky)
- Pay (salary range)
- Location/Schedule info (hybrid/remote)
I should not include the "About Us" as a separate heading? The rules say use
for section headings like "About the role". The "About Us" is company description, but the role description is separate. I'll include "About the role" for the role description paragraph.
The "About Us" could be folded into a short
under "About the role" or separate? The rules say "use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)". It doesn't mention "About the company". But the posting has "About Us" as a section. I think I should include it as a section because it's substantive content about the company. However, the rule says "include a section ONLY when the posting has real, specific content for it". The "About Us" has real content. But the example headings don't include "About Us". I'll include it as "About the Company" or "About Us"? The rule says "e.g." so it's not exhaustive. I'll use "About the Company" as heading.
But the job title is "Senior Software Test Engineer". The posting says "The Software Development Engineer in Test (SDET) is responsible for...". That's the role description. I'll have "About the Role" for that paragraph.
Now, the location/schedule: "The preferred location is Tukwila, WA with the ability to work in the Tukwila office 1-2 days a week but we may be open to strong remote candidates." This is schedule/location info. I could put under a "Schedule" or "Location" heading. The rules mention "Schedule" as a possible heading. I'll create a "Schedule & Location" section.
The US citizenship requirement is a qualification. It's mentioned in Required Qualifications: "Due to program requirements, this position requires US citizenship." Also later: "To conform to U.S. Government space technology export regulations... you must be a U.S. citizen...". I'll keep it in Required Qualifications.
The EEO/legal boilerplate at the end should be removed.
Now, I need to output HTML fragment with and - and
.
