Original description from HN Who is Hiring
Mastra | Customer Engineer | REMOTE (AMER or EMEA time zones) | Full-time 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 We're hiring a customer engineer. Some companies would call this an FDE; we don't, because roughly half the job is shipping in the framework itself. The other half you're embedded with paying customers deploying agents to production: in their Slack channels and on calls, writing code in their repos, reviewing their PRs, working through architecture with their engineers. What you learn there comes back as bug fixes, features, and new primitives in Mastra. One of our current customer engineers is among the top bug-fixers in the entire codebase. You should be a full-stack TypeScript engineer who has built agents and who can explain technical decisions clearly to engineers who haven't seen your code. Remote. We have a lot of EU customers and response-time SLAs, so US Eastern/Central or EU hours work best. Process: a call with Shane (co-founder/CPO, leads customer engineering), a conversation with a customer engineer, a 2-3 hour take-home, then you present it to us and get feedback. Apply: { https://jobs.ashbyhq.com/Mastra/05172cb0-47ec-44f9-9fe8-07d4... } We get back to everyone.
