About The Exploration Company
At The Exploration Company, we are building innovative aerospace technologies that advance the future of space transportation.
The Role
We’re looking for a hands-on Principal Engineer, Test Systems Software to lead the technical direction of our Test Bench Control System software platform.
You will combine deep software engineering expertise with architectural ownership and product-level thinking to ensure our platform reliably supports integrated engine hot-fire testing, while building an architecture that can extend to broader test and ground operations as the program matures.
You will own the software platform that sits between test engineers and the real-time control layer. The platform will enable operators to:
- Author, review, and deploy test sequences.
- Configure and deploy safety parameters onto PLC hardware.
- Visualize live test data.
- Interact with command interfaces.
- Maintain the traceability infrastructure required by test campaigns.
Key Responsibilities
In your capacity as a Principal Engineer, Test Systems Software, you will:
- Define and evolve the platform architecture spanning test sequence authoring, PLC configuration deployment, real-time data acquisition, and operator interfaces.
- Write production-grade code across the full stack while owning the technical roadmap and driving major architectural decisions.
- Translate test requirements and operational needs into feature specifications, managing scope and delivering incrementally toward operational capability.
- Build high-throughput data pipelines for real-time ingestion, processing, and visualization of high-rate sensor data.
- Design the full lifecycle for both operational sequences and configurable safety parameters.
- Define data acquisition standards, including device configuration management and calibration traceability.
- Architect for high reliability, observability, and operational robustness in environments where software faults can have significant hardware and safety consequences.
- Collaborate with Test Bench Engineers, Propulsion, and Systems Engineering to align software capabilities with campaign requirements.
- Lead a multidisciplinary team of five, setting engineering standards, guiding code reviews and design reviews, and balancing development velocity with the rigorous quality bar required for safety-critical infrastructure.
What We Would Love to See From You
- 5+ years of professional software engineering experience, with demonstrated architectural ownership and technical leadership.
- Strong backend expertise, such as Python, C#, or similar, with experience in real-time or near-real-time data processing pipelines.
- Experience with modern frontend technologies, including TypeScript, Vue/React, WebSockets, and operator interfaces or live data dashboards.
- Experience with containerization and orchestration, including Docker and Kubernetes, for deploying and operating distributed service architectures.
- Deep understanding of distributed systems, API design, and inter-process communication in low-latency environments.
- Experience designing software systems that integrate with PLCs or similar real-time controllers, with an understanding of the boundaries between deterministic control and higher-level application logic.
- Familiarity with test bench infrastructure, including instrumentation systems, sensor networks, command/response workflows, and procedural automation.
- Strong understanding of safety-critical software design, including deterministic execution, fail-safe defaults, configuration validation, and safe deployment practices in systems where errors can have hardware consequences.
- A product ownership mindset combined with strong analytical thinking, technical judgment, and attention to detail.
- Motivation to thrive in a fast-paced, mission-driven environment with high accountability for system readiness.
Bonus Qualifications
- Experience in aerospace, defense, or other safety-critical domains, particularly propulsion test operations or environmental test systems.
- Familiarity with Beckhoff TwinCAT or IEC 61131-3 programming.
- Knowledge of data acquisition hardware and software ecosystems, such as Beckhoff, Siemens, or Measurement Computing.
- Experience with hardware interface protocols and device communication, including serial, CAN, and Ethernet-based industrial protocols.
