Constellation Space Software Engineering Intern – Winter

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 Constellation OS 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
.

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 Constellation OS platform.

Depending on the project and the intern’s skills, work may involve:

• Backend software services
• Machine learning
• Networking-related technologies

The role provides an opportunity to apply university-level computer science and engineering knowledge to practical technology development.

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.

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.

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.

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.

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…
