Who we are

At Supermodular AI, we believe AI is revolutionizing the way people and organizations work—making teams more efficient and focused on what truly drives success. We partner with IT organizations to develop tailored AI Agents that seamlessly integrate into enterprise workflows, automate complex tasks and accelerate business outcomes.

Our approach is not about adding more tools but about embedding AI into the systems IT professionals already use, ensuring automation and intelligence align with their unique challenges. From DevOps and cloud migration to cybersecurity and business continuity, our Agents address the most critical pain points by learning from the organization and evolving with its needs.

Though we are a young company, our team has a proven track record in building high-impact AI solutions and scaling engineering teams. With our first clients already benefiting from our technology, we are on a fast-growth trajectory to redefine how IT harnesses AI.

Join us if you’re excited to work in a high-paced, impact-driven environment where AI is not just a tool but a game-changer for real companies. If you thrive on solving complex problems and want to shape the future of intelligent automation, Supermodular AI is the place for you!

Your role

As a Senior Frontend Engineer at Supermodular AI, you’ll take ownership of designing and building user-facing applications that make our AI agents intuitive, reliable, and impactful for enterprise customers. You’ll be responsible for crafting clean, performant, and scalable frontends—primarily with React and Next.js—that integrate seamlessly with our backend systems.

In this role, you’ll collaborate closely with our design and product teams to translate complex workflows into simple, elegant user experiences. You’ll work alongside our engineering leads to make architectural decisions for the frontend stack, while also occasionally contributing to backend services when needed. Just as importantly, you’ll guide and coordinate the work of junior engineers, fostering best practices and ensuring high-quality delivery across the team.

This is a position for someone who not only loves building polished interfaces, but who also enjoys solving end-to-end technical challenges and shaping the frontend architecture that will scale with our growth.

• Ownership of technical scope, making decisions and driving implementation proactively.

• Experience with backend integration, including REST and GraphQL APIs, and the ability to contribute to backend code when necessary.

• Familiarity with cloud-native environments and CI/CD workflows to ensure smooth deployments and scalability.

• Understanding of performance, security, and reliability in frontend applications.

• Experience mentoring and collaborating with junior engineers, ensuring best practices in code quality, testing, and architecture.
