Your role in the team
- Your mission is to design and maintain a scalable, asynchronous backend that powers OKAPI:Orbits' end-to-end solutions across mission design, Space Situational Awareness (SSA), Space Traffic Management (STM), Flight Dynamics (FD), and Space Traffic Coordination (STC), supporting satellite operators throughout their entire mission lifecycle.
- You'll work primarily on external customer projects with a Python-based tech stack, while also contributing to our products built on Java Spring Boot.
- You design and implement robust microservices that process and distribute large volumes of orbital and telemetry data to deliver reliable APIs and automation processes.
- You'll work on the systems that enable satellite operators and space agencies to analyze, coordinate, and protect their missions in an increasingly crowded space environment.
- Design, develop, and maintain asynchronous, microservice-based backend systems, primarily in Python for external customer projects and concurrently in Java Spring Boot for our products.
- Implement and optimize data processing and distribution pipelines that handle large volumes of orbital, telemetry, and mission data.
- Design and maintain message-based communication structures between microservices (e.g., via RabbitMQ or comparable message brokers).
- Collaborate closely with space engineers and scientists to translate mission-related requirements into scalable, robust software solutions.
- Share responsibility for the backend architecture across both tech stacks, with a focus on performance, fault tolerance, and maintainability.
- Plan and document implementation steps, from system architecture through deployment in a cloud-native environment.
- Ensure code quality, automated testing, and adherence to security and development standards.
- Advance CI/CD pipelines, observability, and automation to support stable, continuous releases.
- Analyze and resolve complex issues in distributed systems with a focus on efficiency and reliability.
- Work within small, interdisciplinary teams, contributing your backend expertise to cross-functional projects.
