Entry-level software engineer role on Starlink developing real-time, embedded, and networking software across satellites, ground systems, and consumer devices. Responsibilities include design, coding, testing, prototyping, architecture reviews, and cross-discipline collaboration to deploy reliable software at scale.

Seeking Emerging Modern C++ Developers to create maintainable code for math and physics challenges. Ideal for recent graduates with relevant skills in C++ and additional programming languages.

Develop complex software programs and conduct analysis on systems. Create project plans and specifications while determining product requirements and enhancements.

The Software Tools Engineer will install, operate, and administer ClearCase and ClearQuest tools, develop requirements repositories, use JIRA, and have general scripting knowledge.

Contribute to the software platform for battery energy storage systems, focusing on data engineering, simulation, optimization workflows, and energy market integration.

Develop, maintain, and test complex software systems for the GBSD/Sentinel program. Implement requirements in object-oriented languages, perform design reviews, test software components, resolve defects, and contribute to system-level hardware/software tradeoffs and requirements analysis.

Design, build, test, and maintain software supporting mission-critical systems. Work may include front-end, back-end, testing, integration, APIs, data access layers, automated tests, and documentation. Collaborate with engineers, grow technical skills, and adapt to project needs.

Mark43 is inviting applicants for their engineering team, without a specific role. They'll reach out if a match is found.

The Junior Software Engineer develops and maintains complex software systems, tests components, resolves issues, and collaborates with a team.

Develops and maintains diverse software systems, reviews and tests components, resolves software issues, and analyzes user requirements.

The Software Engineer develops, maintains, and enhances software systems, reviews software components, resolves issues, and inputs to design requirements as part of a team or individually.

Reproduce and debug customer-reported issues, perform root-cause analysis, and validate fixes across customer platforms. Build diagnostic scripts and tools (Python, C#, C++) and AI-driven utilities. Validate NVIDIA products on diverse virtualization and hardware configurations, collaborating with engineers, program managers, and customers to ensure compatibility and reliability.

Begin in customer-facing support to learn codebase, debug software and hardware, deploy and maintain customer environments, and communicate with technical and non-technical stakeholders. Grow into engineering roles building services, APIs, databases, containerized apps, and mobile features while participating in on-call support and customer site travel.

As a Junior Software Engineer, you'll design, develop, and troubleshoot software solutions while gaining experience in an agile team environment.
