“Write a complete job description for a Senior UX Designer role at a Series B startup”
Summary · Write a complete job description for a Senior UX Designer role at a Series B startup, covering responsibilities, qualifications, preferred skills, and company/culture context.
Job descriptions are a well-understood, structured document type with stable conventions. AI handles this task end-to-end with minimal failure risk — the main human effort is customizing company voice, inserting real benefits/comp, and confirming the role scope. No sensitive judgment or accountability concerns that require a human to write from scratch.
Where AI helps most
AI eliminates the bulk of drafting time for a solo expert or small team — reducing a 45–75 minute task to under 30 minutes including review. For recruiting teams posting multiple roles per week, this compounds quickly.

Worker comparison
six profiles| Worker | Time | Cost | Quality & caveats | Conf. |
|---|---|---|---|---|
|
01
Solo Individual
First-timer, no specialist knowledge
|
2–4 hours | $0 direct cost (personal time only) | Will need to research UX Designer skill requirements from scratch, look at template examples, and guess at what's competitive for a Series B context. Likely to miss key tools (Figma, research ops, design systems), misframe seniority expectations, and produce generic boilerplate. Adequate but unlikely to attract strong candidates. | high |
|
02
Solo Expert
Skilled professional in this field
|
45–75 minutes | $75–$150 (blended ~$110/hr for HR/TA professional or experienced UX lead) | An experienced recruiter or UX hiring manager has templates, knows the market, and can tailor the role quickly. Output will be accurate, well-scoped, and competitive. Main risk is lacking deep knowledge of both HR writing and UX domain simultaneously unless they sit at that intersection. | high |
|
03
Small Team
2–3 people, mixed skills
|
1.5–2.5 hours total across team | $250–$450 (HR + UX lead + hiring manager, ~$100–$120/hr blended) | Collaboration between HR, the UX discipline lead, and the hiring manager produces a well-rounded JD that aligns actual role needs with compliant language. Iteration cycles and async back-and-forth add time. Quality is noticeably higher than solo effort — better scoped responsibilities and realistic must-haves vs. nice-to-haves. | high |
|
04
Agency
Professional service provider
|
3–6 hours billable (including briefing, draft, and one revision round) | $600–$1,500 (employer branding or talent consultancy at $150–$250/hr) | Specialist agencies produce polished, on-brand JDs with competitive framing and clear candidate value proposition. They run intake calls to extract context, which takes time. Output is high-quality and differentiated but may feel over-produced for a 1-off internal post unless the startup has active employer branding goals. | medium |
|
05
Enterprise
Large org, process & overhead
|
1–3 days calendar time (4–10 hours of actual work spread across stakeholders) | $800–$2,500 internal loaded cost (HRBP, comp analyst, legal review, hiring manager) | Compliance review, comp band alignment, legal sign-off, and multiple approval layers slow this significantly. Output is thorough and defensible, but often formulaic and slow to publish. Overkill for most startup contexts but reflects real enterprise overhead. | medium |
|
AI
AI (Claude / Agent)
AI plus competent human review
|
15–30 minutes total (1–2 min generation + 15–25 min human review and customization) | $5–$20 (API/tool cost ~$0.10–$1 plus ~20 min of reviewer time at $50–$80/hr) | AI produces a well-structured, comprehensive JD covering responsibilities, requirements, preferred skills, and culture signals quickly and reliably. Failure modes: generic company culture language, placeholder benefits, may not reflect actual internal team dynamics or real comp range. Human reviewer must add company-specific context, verify seniority calibration, and confirm the role scope matches internal alignment. With light review, output is genuinely production-ready. | high |
