# Customer Engineer

**Mastra** · Remote

Apply: https://jobs.ashbyhq.com/mastra/05172cb0-47ec-44f9-9fe8-07d4896d10ad

## About Mastra

Mastra is the easiest way to build a production AI application, built by the team that brought you Gatsby. We provide a complete set of AI primitives: workflows for complex operations, agents for autonomous decisions, RAG for knowledge integration, and evals for quality & accuracy. Mastra is open-source, modular, and built in Typescript for product developers. You can deploy Mastra on any cloud, and it gives you a straightforward syntax to solve the hardest problems building with AI: human-in-the-loop workflows, agent memory and tool selection, and output quality.

## About the role

Mastra is hiring a **Customer Engineer** who operates at the intersection of production reality and core platform design.

This role blends forward deployment and core engineering. You will work directly with teams deploying agents in production and translate what you learn into improvements in the [Mastra framework](https://github.com/mastra-ai/mastra) itself.

#### What You’ll Own

**With **[Customers](https://mastra.ai/customers)** **

- Collaborate directly with customer teams building real agent systems

- Design and implement agents alongside their engineers

- Improve reliability, eval strategies, monitoring, and scaling approaches

- Help teams move from prototype to durable systems

- Train and upskill customers to become Mastra experts

- Share patterns and best practices across accountsWhen agents break or systems stall, you help make them stronger and more repeatable.

**In the Core Framework**

- Turn recurring customer challenges into OSS improvements

- Fix reliability and performance issues

- Ship new primitives and refine existing ones

- Raise the quality bar across the codebase

- Contribute to roadmap direction through firsthand production insightYou’ll convert real-world friction into durable primitives.

#### Who This Is For

This role is for engineers who:

- Have built and operated AI systems in production

- Can move from implementation details to system-level thinking

- See patterns where others see one-off issues

- Care deeply about developer ergonomics

- Prefer ownership over narrow scopeYou should be comfortable moving between hands-on customer collaboration and foundational platform design.

#### Why This Role Is Different

Most companies separate customer-facing engineering from core product engineering. We don’t. The best platform improvements come directly from real-world usage. This role exists to compress that loop. If you want to work on real systems and influence the primitives that define how agent infrastructure is built, this is that role.

#### Hiring Process

1) Intro call with our recruiter

2) Hiring Manager Interview. Call with Shane Thomas, our co-founder and CPO, who leads customer engineering.

3) Peer Interview. Conversation with one of our customer engineers you'd be working alongside.

4) Take-home project `+ project review with our customer engineering team.

#### About Mastra

Mastra is the open-source TypeScript framework for building AI agents. Built by the team behind Gatsby, backed by [Y Combinator](https://www.ycombinator.com) and [Spark Capital](https://www.sparkcapital.com), with $35M raised total. We went from 0 to [27k+ stars](https://github.com/mastra-ai/mastra) and [1M+ weekly npm downloads](https://npmtrends.com/@mastra/core) in under 18 months.

Small team, shipping fast, fully remote. Most of us work across North American and European time zones.
