Opportunities in Lithuania

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, where food is made, minerals are mined, goods are moved, and industries are run, remains far less intelligent, far less efficient, and far more constrained. We’re changing that. Atoms builds Physical AI— real-world robots for the 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, more scalable, and more productive. This work requires more than robotics. It 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. We are roboticists, engineers, operators, and builders. We believe the next great technology companies will not only transform information, but the physical systems that shape everyday life. If you want to work on hard problems with real-world impact, join us.   What you’ll do As a Backend Engineer, you’ll design, implement, and optimize systems that power mission-critical applications. Your role will adapt to your strengths and interests, with opportunities to focus on: Infrastructure: Build and maintain scalable, secure, and high-performance systems to ensure operational reliability. Platform: Develop robust APIs and developer tools to improve team efficiency and scalability. Core Responsibilities Architect and implement scalable backend systems and APIs. Ensure high system performance, reliability, and security. Collaborate with product managers, and other engineers to deliver end-to-end solutions. Participate in code reviews, testing, and documentation to maintain high-quality standards. Mentor junior engineers or take on leadership roles, depending on your seniority.   What we’re looking for  We value diversity of experience and are looking for individuals passionate about solving complex problems. Basic Qualifications: Proficiency in backend programming languages like Java or Go. Familiarity with relational and/or NoSQL databases (e.g., PostgreSQL, MongoDB, Redis). Experience with cloud platforms like AWS, Google Cloud, or Azure. Understanding of RESTful APIs, microservices, and distributed systems. Strong debugging and problem-solving skills. Preferred Qualifications (for Senior Levels) Experience with containerization technologies like Docker and Kubernetes. Knowledge of CI/CD pipelines and DevOps practices. Exposure to large-scale data processing or event-driven architectures. Leadership experience in team projects or mentoring roles.   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. We exist to uncover valuable unknown truths and turn them into progress, which means constantly pushing beyond what’s known and building what doesn’t yet exist. The work is ambitious and often challenging, but it’s grounded in a shared sense of purpose and a team committed to seeing it through together. Our work only matters if it serves others, and we know that meaningful progress depends on the trust of the people we serve and the strength of our team—so we invest in both, creating an environment where you can do your best work and grow.   What else you need to know This role is based in our Vilnius   office.
