Briefs are short editorial dispatches I publish when something newsworthy happens — a major hiring shift, a data-center groundbreaking, a notable corporate move. They show up here as they happen.
Until then, check the global feed.
Every posting is classified into one of three AI buckets: AI required when the description names specific AI tools as required skills (GitHub Copilot, Claude Code, Cursor) or names LLM/agent/RAG/embeddings as core to the day-to-day; AI mentioned when the description mentions AI tooling in passing without it being the core skill; No AI mention when the description contains none of the relevant keywords. Each row shows the matched keyword evidence inline and surfaces named AI developer-productivity tools as expanded-row chips, so you can judge the signal for yourself.
The geographic filter is opinionated. The City of St. Louis (independent city) and St. Louis County postings are always included; so are postings across the surrounding commute shed — St. Charles County (the Mastercard O’Fallon corridor), Jefferson, Franklin, Lincoln, and Warren counties on the Missouri side, plus the Illinois Metro East across the Mississippi: St. Clair County (Belleville, O’Fallon IL, Fairview Heights, Mascoutah and the Scott AFB area), Madison County (Edwardsville, Granite City, Collinsville, Alton, Wood River), and Monroe County (Waterloo, Columbia IL). Remote postings are included only when the employer also has a St. Louis-area office — otherwise anywhere-in-the-US remote noise would swamp the page. Use the Location filter to narrow to a specific city.
This page is an independent aggregation. Mungomash is not affiliated with or endorsed by any of the employers listed. Application-status tracking and email alerts are out of scope. Per-posting salary ranges are surfaced inline when the employer discloses one — structured ATS fields first, JD-body prose as a fallback; rows with no disclosed range render no chip. For broader salary context, see H-1B Salaries (visa-petition disclosures) and Dev Wages (national survey).
