Ground Systems / Testing Infrastructure Intern

TL;DR

Ground Systems / Testing Infrastructure Intern (Python/Linux): Assist in developing and maintaining Software-in-the-Loop (SIL), Processor-in-the-Loop (PIL), and Hardware-in-the-Loop (HIL) test infrastructure with an accent on test orchestration, telemetry/command scripting, and integration with mission control software. Focus on building realistic “Test-As-You-Fly” environments and improving automation and tooling performance for spacecraft verification and operations.

Location: Tokyo, Japan (ispace HQ, Nihonbashi Honcho) — on-site at least 3 days/week; flexible WFH up to 2 days/week (not full remote)

Company

iSpace develops mission-driven space systems and supports spacecraft test and flight operations through ground systems and testing infrastructure.

What you will do

• Develop, maintain, and configure SIL/PIL/HIL test environments to support testing campaigns.
• Implement and expand Python tools for test setup, execution, and reporting.
• Write and test scripts for telemetry generation and command injection for closed-loop testing.
