A new open-source dashboard from GantryOps called HN Jobs Trends shows that 63.1% of job postings in the March 2026 Hacker News "Who is Hiring?" thread mention AI/ML — a 2.5 percentage-point increase from the previous month. The dashboard, available at hn-job-trends.gantryops.dev, analyzes 363 listings collected on the 3rd and 28th of each month, classifying them using <a href="/news/2026-03-14-andrej-karpathy-scores-ai-exposure-of-342-us-occupations-using-gemini-flash-llm">Google Gemini Flash</a> against a fixed taxonomy covering roles, technologies, experience levels, compensation, and work arrangements.
Traditional titles still dominate the role breakdown — Senior Software Engineer (24%), Full Stack Engineer (22%), and Backend Engineer (13.5%) — but AI-native roles are consolidating meaningful share. ML Engineer postings represent 5% of all listings, up 2.1 percentage points month-over-month, while AI Engineer accounts for 4.4%, putting the two categories together at nearly 10% of total postings. Senior-level positions make up 48.5% of all listings.
Compensation data shows a sharp shift: 31.4% of listings now explicitly mention salary, up 4.6 percentage points — the biggest single-month jump in the tracked metrics. The most common salary band is $150k–$200k (49 listings), followed by $200k+ (40 listings). On work arrangements, fully remote roles account for 41.3% of postings, though onsite-only (24.5%) and hybrid (20.1%) positions together outnumber remote when combined.
GantryOps flags a methodological limit: with only 363 listings in the sample, month-to-month percentage-point swings can be amplified by small absolute count changes. The site's History section, which tracks longer-horizon trends, offers a more reliable signal.
