Member of the technical staff (Software Engineer)

Jua

OVERVIEW Physical AI, a real model of the world, is the next trillion dollar opportunity and a foundational pillar for energy, robotics and superintelligence. At Jua we are building it now. Our models already run on four continents and help power the energy buildout needed to support ever larger intelligence. We are assembling a world-class team of researchers and entrepreneurial minds to turn this model into reality at global scale. If you want the opportunity of your life, come build physical AI with us. WHAT WE’RE LOOKING FOR We’re redefining earth simulation 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. OUR TECH STACK * 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 ClickHouse cluster for analytics workloads and PostgreSQL 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. RESPONSIBILITIES AND TASKS * 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 to 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. NEED-TO-HAVE * 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 in identifying problems, performance bottlenecks, and areas for improvement. * Nice-to-have: Exposure to Data Engineering or related experience. AT THE END OF YOUR FIRST 30 DAYS, YOU WILL HAVE * Gained deep product immersion: Understood the “what” and “why” of the product, contributed to discussions, formed opinions and comfortably expressed them, and actively participated in team retros. * Deployed scoped components: Delivered isolated, limited-scope features, addressed feedback, and deployed quickly with minimal supervision, making confident decisions along the way. * Contributed your valuable insights to system architecture and design discussions, effectively collaborating with the rest of the engineering team to set architectural goals. * Engaged with Jua’s principles and values: Collaborated across teams and built independent working relationships. ABOUT YOU * You work in alignment with our operating principles. These principles guide how we make decisions, collaborate, and build at Jua. You embody them in your work, continuously evolving as we evolve, and integrating them into everything you do. * You take initiative and drive action. You proactively identify challenges and opportunities, taking ownership without waiting for direction. You thrive in an environment where autonomy and action lead to impactful results. Rather than waiting for permission, you step forward, solve problems, and drive meaningful change. * You are adaptable and resourceful. You’re comfortable navigating ambiguity, making data-informed decisions, and iterating as you go. Limited resources don’t slow you down—they inspire creative problem-solving. Whether working with evolving technologies or shifting priorities, you find a way forward and deliver exceptional outcomes. * You thrive in a fast-paced team. We work extremely hard to be the fastest in our field, speed and excellence are non-negotiable. You’ll be surrounded by overperformers in every discipline, and we expect the same from you. If you don’t consider yourself among the best in your field, Jua likely isn’t the right fit. * Our feedback culture is radically transparent and truth-seeking. This can be intense if you’re more used to comfort than candor, but for those who thrive on challenge, it’s an environment where you’ll grow fast and do the best work of your career. Please note: We prioritise your answers to the application questions over your CV, so we encourage you to complete them as thoughtfully and thoroughly as possible. At Jua, we foster a performance culture and value people who embody our beliefs of service and adventure. We prioritize agility, operating at the highest clock speed to adapt quickly to change. We innovate on behalf of our users and leverage data supremacy to maintain our competitive edge. Through clear communication and fact-based decision-making, we ensure alignment in our pursuit of excellence. With these principles, we aim to create a customer-focused, value-centric organization that sets new standards in the industry. We value the unique perspectives that each individual brings to the table and believe that embracing diverse backgrounds and experiences enriches our collective journey towards growth and success.
