Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

We are seeking a talented Industrial Software Engineer to help us in our mission by developing middleware that interfaces with Beckhoff PLC systems and enables robust, real-time communication with our test infrastructure. You'll design and maintain software that abstracts PLC communication and exposes clean APIs for our operator-facing interfaces and data analysis platforms.

Key responsibilities:

• Design, implement, and maintain a middleware layer that communicates with Beckhoff TwinCAT PLCs using ADS.NET
• Expose real-time telemetry and control interfaces through robust APIs (e.g., gRPC, WebSockets, or REST)
• Implement symbol mapping, subscription handling, reconnect logic, and a simulation mode to support testing workflows
• Collaborate with HMI, PLC, and test engineers to align on data models, safety-critical interactions, and performance requirements
• Contribute to the reliability and maintainability of our test infrastructure by ensuring fault tolerance, clear observability, and long-term maintainability

What we would love to see from you:

• Strong experience with Beckhoff TwinCAT 3 and communication via the ADS protocol
• Proficiency in C# / .NET, including API development and service architecture
• Familiarity with real-time or near-real-time systems and PLC-based software integration
• Experience designing typed APIs and data models for communication across systems
• Ability to work closely with HMI and PLC teams to create smooth, reliable interfaces
• Solid understanding of software design patterns and best practices
• Hands-on experience with agile software development methodologies
• Motivation to work in a fast-paced environment with demanding timelines
• High attention to detail with an ability to balance quality & speed
• Strong analytical and problem-solving skills
• Fluency in English

Desirable:

• Experience in API design with gRPC
• Exposure to containerization with Docker
• Familiarity with HIL/SIL setups, test automation, or control software in aerospace/automotive contexts
• Understanding of industrial networking (e.g., EtherCAT, OPC UA) or safety-critical software constraints

Why you should join us!

What makes us special here at The Exploration Company and why we think you will enjoy working here is:

• We're Agile - we make decisions fast whilst keeping our goals and systems in mind
• We're Open and Collaborative - we are transparent about risks and obstacles, so that we can cooperate to overcome them
• We have a lot of Fun - we refuel our energy knowing we are democratising space. It's a wonderful and rare opportunity, are YOU up for the challenge?
