SWISSto12 is one of the world’s fastest-growing aerospace companies, evolving from its pioneering use of 3D printing technologies for high-performance Radio Frequency (RF) products and applications to recently announcing the manufacture of entire geostationary telecom satellites, called HummingSat, that define a new category in space. HummingSat is the world’s first commercial telecom GEO SmallSat developed in collaboration with the European Space Agency (ESA). Its uniquely compact size combined with highly capable telecom payloads allows telecommunications operators to deploy a cost-efficient, compact, and agile asset without sacrificing performance or security. HummingSat has been selected by Intelsat to build the I-45 satellite, by Inmarsat to build three I-8 satellites, and recently by Astrum Mobile to build the NEASTAR-1 satellite. SWISSto12 is also a leading provider of Radio-Frequency (RF) products and sub-systems for satellite communication and remote sensing applications. The company’s patented 3D printing technologies and associated product designs are unique to deliver lightweight, compact, highly performing, and competitive RF products.Responsibilities Lead the design and implementation of full-stack applications across several programs, covering backend services, frontend applications, and database architecture Contribute to system architecture decisions, including modularization, service decomposition, integration patterns, and technology trade-offs Participate in the full SDLC: requirements analysis, solution design, implementation, peer reviews, testing, deployment, production support, and continuous improvement Implement and promote engineering best practices for testing, logging, documentation, code review, traceability, and maintainability Define and improve CI/CD pipelines, automated build/test/deploy workflows, release readiness, and deployment quality gates Build product-quality user interfaces for engineering workflows, including simulator-facing and command/telemetry-oriented interfaces where applicable Develop and evolve ground operations tools, supporting mission readiness, command preparation, telemetry monitoring, anomaly investigation, and operator workflows Work closely with spacecraft, payload, AIT, and ground segment stakeholders to translate operational concepts into reliable, maintainable, and traceable software capabilities Mentor other engineers through design reviews, code reviews, technical coaching, and collaborative problem solving Identify technical debt, propose pragmatic improvements, and help shape engineering standards for long-term sustainability Partner with infrastructure and DevOps teams to improve environments, deployment automation, observability, reliability, and operational support Ensure software is built with security by design, including authentication/authorization, secure secret handling, input validation, least privilege principles, and secure API practices Requirements Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related technical discipline 7+ years of professional software development experience, including experience building, deploying, and maintaining production applications Strong backend development experience in Python, including building web services and APIs with Flask or similar frameworks Strong frontend experience with Angular/TypeScript-based web application development.
