Job Description

Job Title: Software Engineer, Financial Platform

Job Type: Full-Time

Location: Remote

The Role:

We are looking for a Software Engineer to help design and build next-generation financial technology systems. This role sits at the intersection of product development, infrastructure, and applied engineering, focusing on creating reliable, scalable applications that deliver thoughtful user experiences.

What You'll Do

Write, ship, and maintain production code daily across fullstack applications using Node.js, React.js, Next.js, and PostgreSQL.
Build scalable backend services and RESTful APIs on AWS infrastructure.
Implement responsive, maintainable frontend interfaces you should be equally comfortable debugging a React render issue and tuning a Postgres query.
Collaborate with cross-functional teams to turn product requirements into shipped features.
Uphold high standards for system reliability, security, and data integrity in financial systems.
Actively contribute to CI/CD pipelines, code reviews, and engineering best practices.
Communicate clearly in code, documentation, and team discussions.

What We're Looking For

5+ years of professional software development experience, with active hands-on coding in the last 12 months across both frontend and backend.
Strong, recent backend development experience with Node.js (please share what you have shipped in the last year).
Recent, advanced frontend experience with React.js and Next.js — including hooks, state management, and modern Next.js features (App Router, SSR/ISR).
Solid working knowledge of PostgreSQL: schema design, query optimization, indexing, and data modeling.
Hands-on experience with AWS services such as EC2, S3, Lambda, RDS, and CloudWatch.
Demonstrated experience designing and integrating REST APIs in production.
Proficiency with Git, CI/CD workflows, and agile development.
Clear written and verbal communication.

Nice to have

Experience with Python.
Experience building or maintaining financial or fintech systems.
Familiarity with Docker, Kubernetes, GraphQL, Redis, and caching strategies.
Experience with microservices and modern testing frameworks (Jest, PyTest, Cypress).

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.
