Drive data validation, error handling, and security best practices within backend services.
Plan and execute database migrations, optimizations, and schema changes as needed.
Actively test new AI-powered models in Cursor, providing actionable feedback via incident reports, bug traces, and screenshots.
Participate in 4-day intensive testing bursts, exploring how AI models impact real coding workflows.
Engage thoughtfully with the research team in a dedicated Slack channel to discuss findings and propose improvements.
Submit detailed post-burst surveys, delivering insights on model performance and developer experience.
Required Skills and Qualifications:
3+ years of professional experience as a backend developer, with strong expertise in Python.
Proficient in building and maintaining RESTful and GraphQL APIs.
Advanced understanding of backend data validation, error handling, and API security.
Hands-on experience with database migrations, performance tuning, and schema design.
Extensive use of AI tools for coding; familiarity with Cursor is highly desirable.
Outstanding written and verbal communication skills, with a knack for clear incident and bug reporting.
Proven ability to thrive in fast-paced, confidential, and collaborative remote environments.
Preferred Qualifications:
Visible contributions to open source (e.g., GitHub stars or contributions).
Experience designing or evaluating experimental tooling and developer workflows.
Demonstrated enthusiasm for AI advancements in software development.
About Micro1
Micro1 is building the essential infrastructure for the next generation of artificial intelligence, moving beyond the limitations of static datasets to create a dynamic ecosystem where models truly learn to think and act. At its core, the company understands that the path to frontier intelligence isn't paved with synthetic data alone; it requires the nuance, judgment, and contextual awareness that only expert human guidance can provide. By positioning itself at the intersection of human expertise and advanced reinforcement learning, Micro1 is tackling the hardest problem in AI today: teaching models not just to answer questions, but to reason through complexity and take meaningful actions in unpredictable, real-world environments.
This mission comes to life through Realm, Micro1's flagship training environment. Realm functions as a high-fidelity simulation ground where AI agents are immersed in scenarios that closely mirror the messiness of actual human workflows. Rather than relying on abstract benchmarks, Realm forces models to engage in agentic actions, multi-step decisions, digital navigation, coding, and problem-solving that require genuine comprehension. It is within these realistic sandboxes that world-class human data is generated, creating a continuous feedback loop where expert annotators observe, correct, and guide model behavior. This process does more than just fine-tune outputs; it fundamentally elevates a model's underlying reasoning architecture, ensuring that the intelligence developed in training holds up when deployed into the wild.
But training is only half the equation. Micro1 recognizes that the true test of an AI system lies in its production performance, which is where Cortex enters the picture. Cortex is a contextual evaluation platform designed to move beyond superficial accuracy metrics and provide a granular, real-time view of how agents behave in live settings. It doesn't just flag errors; it surfaces the underlying context behind failures, revealing why an agent struggled with a particular user intent or environmental variable. This insight is invaluable for engineering teams, as it transforms evaluation from a passive checkpoint into an active improvement tool. With Cortex, companies can catch degradation early, understand the nuances of edge cases, and feed those learnings directly back into Realm for retraining, creating a virtuous cycle of continuous advancement.
Ultimately, Micro1 is not merely a data lab or an evaluation tool it is a comprehensive intelligence engine that connects the entire lifecycle of model development. From the expert human feedback that sharpens raw capability, to the realistic RL environments that forge robust agentic behavior, to the contextual oversight that ensures reliability in production, Micro1 provides the integrated foundation that AI labs and enterprises desperately need. As the industry races toward truly autonomous systems, Micro1 stands as the critical bridge between laboratory breakthroughs and dependable, real-world impact, ensuring that frontier models do not just perform well on paper, but deliver genuine value in the complex, dynamic world they are meant to serve.
