About this role

**Who we are** Atoms is building the machines that power the next era of progress. Over the last decade, software has transformed the digital world—but the physical world (food, mining, transport, and more) remains far less intelligent, efficient, and scalable. We’re changing that. Atoms builds **Physical AI**—real-world robots for industries that move civilization forward (starting with food, mining, and transport). Our systems are designed to understand, predict, and control the real world with precision, turning complex physical operations into something more reliable, scalable, and productive. This work requires deep integration across **hardware, software, AI, operations, manufacturing, and real estate**. We don’t just build machines in a lab—we deploy them into real environments, operate them, learn from them, and improve them until they work at scale. If you want to work on hard problems with real-world impact, join us. --- **What you’ll do** - Build end-to-end applications and APIs that power our autonomous vehicle platforms and systems. - Architect and implement real-time user interfaces for internal and external customers. - Build modern frontend and backend experiences that surface insights from high-dimensional data. - Debug complex issues across our engineering and data stack. - Partner with product, design, and engineering to take systems from concept to production. - Drive code reviews, testing, and documentation, and mentor engineers as you grow into technical leadership. --- **What we’re looking for** - 3+ years building full-stack systems, with proficiency in **TypeScript, Python, or a similar language**. - Deep understanding of **RESTful APIs, microservices, and distributed systems**. - Experience building **real-time systems** with stateful protocols (e.g., **WebSockets, gRPC streaming**). - Strong command of **relational and/or NoSQL databases** (e.g., **PostgreSQL, MongoDB, Redis**). - Excellent debugging and problem-solving instincts under production pressure. - Experience mentoring engineers or leading team projects is a plus. --- **Why join us** At Atoms, you’ll work on one of the defining challenges of our time—bringing automation into the physical world to drive real, lasting impact.
