As part of a small, highly technical team, you’ll work closely with the founders, designers, and engineers to help execute the company’s mission.

The platform is multi-disciplinary, and the tech stack reflects that. The backend is built with Java, Python, and Go, while the frontend uses TypeScript and Next.js. They use Postgres, Timescale, and Redis for storage, and run their infrastructure on AWS, Azure, and Terraform, supporting both internal services and customer deployments.

Real-time data pipelines and edge computing are central to the platform, with Apache Flink and cloud IoT platforms playing a key role.

• Embed a culture & implementation of software engineering best practices, from design to testing & deployment
• Rapidly fix bugs and be a technical partner to the customers
• Own the code-base, develop deep domain expertise

Requirements:

• 7+ years of backend experience, with deep Java expertise
• Strong background in Apache Flink & Kafka
• Experience building & deploying APIs
• Solid grasp of OOP, data structures, and system design
• Experience with cloud-based infrastructure (AWS & Terraform; Azure is a plus)
• Deep understanding & knowledge of testing frameworks
• Ability to write efficient, secure, well-documented, and clean code
• Strong problem-solving and critical-thinking abilities

Nice to have:

• Experience with Golang
• Familiarity with Python
• Experience with industrial protocols (i.e. MQTT, EtherNet/IP etc)
