Model ML is an AI-native workspace initially designed for investment banking, private equity, consultancies, and asset managers. You will work alongside two well-known founders who successfully sold their last two YC-backed companies. Model ML, has already raised double figures from Y Combinator and top-tier venture firms. With strong product-market fit and live production deployments at some of the world's largest and most prestigious institutions, Model ML's team is working around the clock across offices in New York, London, and Hong Kong to become the leading AI application platform for enterprise.

Soon, all your digital information will be stored in one place. Everything you do, whether that be sending emails, building presentations, having meetings, pulling data, or doing research, will all be underpinned by an AI model that belongs to you. Using Model ML, you'll simply talk to your laptop or phone to get things done.

We are seeking a highly skilled Full-Stack Engineer with at least 5 years of professional experience to join our growing team. The ideal candidate has a strong background in building modern web applications, is fluent in React/Next.js, experienced with backend development (Python preferred), and has hands-on exposure to infrastructure and DevOps practices.

Key Responsibilities

• Design, develop, and maintain frontend applications using React and Next.js.
• Build, test, and deploy backend services and APIs (Python/Django/FastAPI preferred, but other languages/frameworks welcome).
• Collaborate with founders, growth team, designers, and other engineers to deliver high-impact features.
• Ensure scalability, performance, and security across the stack.
• Implement CI/CD pipelines, automated testing, and monitoring solutions.
• Contribute to infrastructure planning, deployment, and optimization in cloud environments (AWS, GCP, or Azure).
• Mentor junior developers and promote engineering best practices.

Required Qualifications

• 5+ years of professional software engineering experience.
• Proven experience with React and Next.js in production environments.
• Strong backend development skills (Python preferred)
• Solid understanding of relational and/or NoSQL databases.
• Experience with Git and collaborative development workflows.
• Knowledge of cloud infrastructure, containerization (Docker, Kubernetes), and CI/CD pipelines.
• Strong problem-solving skills and a passion for building great products.
• Experience implementing background workers and task queues (Celery, RQ, etc.).
• Proficiency with Redis for caching, pub/sub, or job queues.

What We Offer:

• You will be reporting directly to the founders, who have two successful venture-backed exits under their belt.
• Competitive salary + equity
• Supportive and innovative work environment.
• Opportunity to help shape and build a generational company

What you can expect:

• It won't be easy; in fact, it will be very hard.
• BUT, it will be a lot of fun.
• You need to be comfortable with being uncomfortable; timelines will change, priorities will most likely shift.

To conclude, we're building a team of like-minded, incredibly smart, tenacious individuals with relentless work ethic and focus, all driving towards our very clear revolutionary mission. If you match this description, buy into that mission and you're at a career stage where you're ready to make your defining statement to the world, please apply.
