Jua is building the most advanced Earth intelligence platform ever created: a universal physics simulator designed to turn the planet’s raw complexity into decisive trading upside. Today, our technology delivers the world’s most advanced weather models and analytics, giving energy companies and traders a significant edge: higher profits, smarter risk, faster execution.

With this universal simulator, we collapse barriers to understanding Earth’s systems, enabling the efficient and sustainable use of natural resources while improving standards of living and spurring economic growth.

To make this vision a reality, we have assembled a talented multidisciplinary team, and we are still growing. By joining us, you will help shape a culture of ambition, transparent communication, and rapid iteration, while taking on exciting challenges with creative freedom, fair pay, and generous stock options.

We’re redefining weather forecasting with machine learning, building a system that outperforms traditional models in speed, precision, and accuracy. Our team moves fast, leveraging a versatile tech stack and state‑of‑the‑art cloud infrastructure to maximize performance and efficiency.

We believe in using the right tools for the job. We are combining robust web technologies, advanced ML frameworks, and powerful numerical computing. With a focus on type‑safe programming and infrastructure‑as‑code, we ensure scalability without excess complexity.

As a Software Engineer, you’ll help shape our backend systems, pipelines, and cloud infrastructure. You’ll thrive in ambiguity, iterate fast, and turn ideas into working prototypes. If you have a hacker’s mindset, love building from scratch, and excel in lean, high‑impact environments, we’d love to hear from you.

• Core
  
  Languages:
  
  Python is our go‑to for backend development, data pipelines, and ML integration. Deep experience with modern Python is a must.
• Databases & Storage:
  We operate a large Click House cluster for analytics workloads and Postgre
  
  SQL for transactional data. Experience with distributed databases and data modeling is highly valued.
• Data Pipelines & Orchestration:
  We build reliable, scalable data pipelines using Dagster for orchestration and comprehensive observability.
• Cloud & Infrastructure:
  We use a mix of cloud (AWS) and bare metal infrastructure, with tools like Terraform for infrastructure‑as‑code.
• Other Tools:
  While Python is our primary language, we believe in using the right tool for the job. You’ll have the freedom to introduce new technologies when they make sense.

• Build scalable systems:
  Design, develop, and deploy backend pipelines, services, and cloud infrastructure with a focus on speed, scalability, and pragmatism. You’ll work across the stack—from database systems to occasional front‑end integrations and CI/CD pipelines—in a mixed multi‑cloud and bare metal environment.
• Help shape our architecture and roadmap:
  Play a key role in defining how we build and scale. As an early senior engineer, you’ll influence technical strategy, refine system architecture, and ensure long‑term maintainability while moving fast.
• Bring ML models to production:
  Work closely with ML engineers to deploy models that power real‑world decision‑making, ensuring performance, reliability, and usability for customers, including power traders.
• Identify and tackle technical challenges:
  Address performance bottlenecks, refactor critical systems, and strike the right balance between rapid iteration and long‑term stability.
• Prototype and iterate quickly:
  Move fast, test ideas, and refine approaches with short feedback cycles to drive continuous improvement.

• Bachelor’s degree (or higher) in Computer Science or a related field.
• 3+ years of experience in a Software Engineering role.
• Strong experience in deploying and supporting large‑scale production systems.
• Ability to make pragmatic, fast‑paced architectural decisions while managing technical debt effectively.
• Proactive…
