At Spaceium, you’ll drive innovation by designing and building the software that powers our spacecraft. As a Software Engineer, you’ll develop critical systems for flight software, data processing, control algorithms, and automation tools. Your work will involve coding, testing, and deploying robust solutions for space environments. Collaboration across disciplines is key, and you’ll need a deep understanding of software development principles, aerospace standards, and a passion for pushing the boundaries of technology. Responsibilities: Design and develop software systems for spacecraft, including flight software, control systems, and data acquisition pipelines. Write clean, maintainable, and efficient code using programming languages such as Python, C++, or Rust. Develop and maintain real-time systems for spacecraft operations, ensuring high reliability and fault tolerance. Perform rigorous software testing, including simulation, integration, and validation, to ensure functionality in challenging space environments. Collaborate with hardware and systems teams to integrate software with avionics, sensors, and actuators. Implement industry-standard communication protocols such as RS422, I2C, CAN, and Ethernet in software applications. Adhere to industry-standard aerospace protocols and implement design methodologies for space applications. 1st software engineer reporting directly to CTO. Basic Qualifications: Bachelor’s degree in Computer Science, Software Engineering, or a related field. 2+ years of experience in software development or a similar role. 1+ years of experience using development tools such as Git, CI/CD pipelines, or testing frameworks. We’re working on stuff that’s never been done before, so experience isn’t a big deal. It’s nice if you have it, but it’s not a must. If you’re excited to learn, ready to put in the work, and want to shake things up in the space industry, go ahead and apply! Whether you’re fresh out of school or have years under your belt, we’d love to hear from you. Preferred skills and experience: Passion for spaceflight and high-reliability software systems, with familiarity in aerospace software practices. Self-starter with experience delivering software under tight time and resource constraints. Creative problem solver with strong first-principles thinking, capable of assessing risk and making decisions with limited data. Experience in a nimble, technical engineering role, with a scrappy, entrepreneurial approach to meeting tight time or budget constraints. Proficiency in software development tools, version control systems, and best practices for high-reliability applications. Strong understanding of communication protocols, data pipelines, and real-time system performance. Excellent verbal and written communication skills, collaborative team player, and detail-oriented with a focus on quality. Additional Requirement: Extended hours and weekend work may be required to support critical project and mission milestones. Compensation: Pay range: $90k-$110k USD per year Equity range: 0.1% - 1%
