Ship AI agents that reason, remember, and act in TypeScript. Mastra provides memory, tools, MCP, and observability to go from prototype to production. Backed by Y Combinator.
About the role
Build the features that make this possible: tools for understanding traces, evaluating agent behavior, and turning results into improvements. Run experiments on Mastra’s primitives, investigate where they perform well and where they fall short, and use those findings to improve their configuration and behavior. You’ll help turn that work into capabilities developers can use in their own applications. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Shipped agents and agentic applications into production
- Tuned and tweaked them to improve accuracy
- You need to be able to benchmark your results against existing datasets, or intelligently creating
More about this role
We’re looking for an AI engineer. You’ll work on features that help developers understand their agents’ behavior, evaluate their performance, and improve them over time.
This is a hands-on engineering role. You’ll move between experiments, benchmarks, and product code, taking what you learn from evaluating agents and using it to shape the framework.
We’re starting to build more and more agentic features into Mastra: Trace intelligence, and we’re working on various Agent Learning features to automatically self-improve agents (Autoevals + Suggestions, Rollouts).
In addition, we’ve been increasingly running Mastra primitives like memory on industry-standard benchmarks and using the results to fine-tune configuration.
