Constellation Space is seeking a Software Engineering Intern to join its Engineering team in Seattle, Washington, and contribute to the development of the company’s ConstellationOS platform.
The full-time, on-site internship offers students the opportunity to work on a real engineering project from initial design through deployed code. Interns may contribute to areas including backend services, simulation, machine learning and developer tools.
Two internship terms are available: a Winter 2026 internship beginning in November 2026 and a Spring 2027 internship beginning in Spring 2027.
The position offers compensation of $6,000–$7,000 per month, together with a $3,000 relocation stipend.
About the Constellation Space Internship
The Software Engineering Internship is designed for students who want practical experience building software for a space technology environment.
Rather than working solely on small supporting tasks, interns will own a scoped project and take responsibility for developing and deploying their work. This provides exposure to the full engineering lifecycle, including design, implementation, testing, code review, documentation and presentation.
Interns will work alongside the Constellation Space engineering team and contribute directly to the ConstellationOS platform.
Areas of Work
Depending on the project and the intern’s skills, work may involve:
- Backend software services
- Simulation environments
- Machine learning
- Developer tools
- Data pipelines
- Systems engineering
- Networking-related technologies
- Platform development
The role provides an opportunity to apply university-level computer science and engineering knowledge to practical technology development.
Key Responsibilities
The Software Engineering Intern will be expected to:
- Build and ship a scoped feature or engineering tool.
- Write tested and reviewable production-quality code.
- Document technical work and implementation decisions.
- Support data pipelines or simulation environments where required.
- Collaborate with the engineering team throughout development.
- Present completed work to the team at the end of the internship term.
The role therefore combines hands-on software development with collaboration, documentation and technical communication.
Eligibility Requirements
Applicants must currently be pursuing a Bachelor’s or Master’s degree in Computer Science, Engineering or a related field.
Candidates should also demonstrate strong programming ability in Python, Go, C++ or a comparable programming language.
Experience or coursework in the following areas is advantageous:
- Computer systems
- Networking
- Machine learning
- Software engineering
- Simulation
- Data processing
The position is particularly suitable for students who have developed practical programming experience through academic projects, research or previous technical work.
U.S. Person and ITAR Requirement
A key eligibility requirement is that applicants must be a U.S. person, as the position is subject to ITAR (International Traffic in Arms Regulations) requirements.
Applicants who do not meet the applicable U.S. person requirement should verify their eligibility before applying.
Location and Work Arrangement
The internship is full-time and on-site in Seattle, Washington.
Interns must be able to work on-site in Seattle for the entire internship term.
Two terms are available:
Winter Internship: Starts November 2026
Spring Internship: Starts in Spring 2027
Candidates should ensure that their academic schedule allows them to complete the selected internship term on-site.
Salary and Benefits
The internship offers:
Monthly compensation: $6,000–$7,000
Relocation support: $3,000 stipend
Employment type: Full-time
Work arrangement: On-site
Location: Seattle, Washington
The opportunity provides students with both financial compensation and practical experience working on real software projects in a space technology environment.
Why Apply?
The Constellation Space internship offers students an opportunity to move beyond classroom-based programming and contribute to software that supports a real technology platform.
Interns can gain experience across the complete software development lifecycle, including system design, coding, testing, code review, deployment and technical presentation.
The opportunity may be particularly valuable for students interested in software engineering, aerospace technology, space systems, machine learning, simulation, backend development and developer infrastructure.
How to Strengthen an Application
Candidates can strengthen their applications by demonstrating practical programming ability through academic, personal or research projects.
Relevant projects involving Python, Go, C++, machine learning, systems, networking, simulation or backend development should be highlighted. Applicants should also demonstrate their ability to write maintainable code, collaborate with other developers and take ownership of technical projects.
Candidates should clearly indicate their availability for the full internship term and confirm that they satisfy the U.S. person requirement before applying.
