Grade D

Why this grade This listing scored 52/100, which is a D. It lost the most ground on pay transparency. See the breakdown

Freshness 15 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
Description depth 14 / 20 How much the posting actually says about the work, measured in characters of real text.
Corroboration 5 / 10 Whether more than one source carries this listing.
Role specificity 3 / 10 Whether the listing is tagged well enough to tell what the role actually is.
Pay transparency 0 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.

Every figure above is arithmetic over the posting itself — its salary field, its text, its age, its tags and how many sources carry it. How the grades work →

This listing does not state a salary

$87k – $179k

That is the middle half of what comparable roles paid on this board over the last 90 days — 747 listings that did publish a figure, median $130k. It is not this employer's offer, and we have no idea what they pay. It is only what the rest of the market advertised.

hn-hiring

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra
Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.
What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.
You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.
Apply: { https://jobs.ashbyhq.com/Mastra/d5fe8d36-843a-4f9b-9d65-779e3b25174d } We get back to everyone.
