The Opportunity
We are seeking a highly skilled and motivated Senior Backend Engineer to join our Workforce Team. In this role, you will be a key driver of the Workforce Suite—our mission-critical software ecosystem that includes the Data Navigator, Mission Controller, and Field Operator App. You won't just be writing code; you will be designing the robust, scalable systems that allow our autonomous robots to communicate, report, and operate in the world’s most challenging industrial environments. This is a high-impact role where your expertise in modern backend architecture will directly influence how humans and robots collaborate at scale.
The Market & Our Technology
ANYbotics is transforming industrial inspection with ANYmal, the world’s most advanced autonomous four-legged robot. Our technology is deployed globally across energy, chemicals, and mining sectors to increase safety and efficiency. To support these deployments, we build a sophisticated cloud and edge-based infrastructure. Our backend stack is centered around Node.js and TypeScript, utilizing NestJS, PostgreSQL, and MQTT to handle real-time robot telemetry and complex data orchestration. We move fast, prioritize clean architecture, and solve problems that exist at the intersection of the physical and digital worlds.
