Software & Simulation Test Design Engineer

We are seeking a Software & Simulation Test Design Engineer to architect and lead the development of a unified test software framework and simulation that ensures consistency, scalability, and reliability across global engineering teams. This role is central to establishing standardized testing practices, simulation environments, and automation infrastructure that enable high-confidence validation of mission-critical systems.

You will define test software across the organization—creating a cohesive ecosystem that spans simulation, hardware-in-the-loop (HIL), integration, and system-level testing—while enabling teams in different regions to operate efficiently within a shared framework.

Test Framework Architecture: Design and evolve a modular, global test framework supporting unit, integration, system, and simulation-based testing. Define reusable abstractions, APIs, and libraries for consistent implementation, including fault injection scenarios such as sensor dropouts, thruster misfires, and communication delays.

Simulation & Test Infrastructure: Architect scalable simulation environments and virtual testbeds with seamless HIL/SIL integration, covering orbital mechanics, space environments (vacuum, radiation, thermal), and spacecraft dynamics including attitude control and propulsion.

Global Standardization & Governance Establish: common testing strategies, naming conventions, data formats, and reporting standards across regions. Define quality metrics, coverage standards, and quality gates; lead architecture and test design reviews to enforce best practices.

Automation & CI/CD: Build and standardize automated test pipelines within CI/CD workflows, ensuring tests are reliable, reproducible, and scalable across distributed environments.

Performance & Mission Scenario Testing: Ensure test systems support large-scale simulations, high data throughput, and long-duration runs — including thousands of simulated missions across launch windows, environmental variations, and anomaly scenarios. Optimize for speed, determinism, and debuggability.

Cross-Functional Leadership: Collaborate with global engineering teams to drive adoption of the test framework. Contribute to resource estimation, schedule planning, and risk identification. Embody ispace values — Diversity, Integrity, Respect, Collaboration, and Accountability — and stay current on emerging tools and methodologies.
