Software Engineer

Software Engineer About the job At Capture Energy, we’re transforming our automation architecture and are looking for a Software Engineer – Operational Technology & Cloud Integration to build core services on our Capture Controller while ensuring seamless data flow to our cloud infrastructure. You’ll create lean, maintainable applications and clean interfaces between our operational technology and cloud systems. We primarily develop in Go, but we’re equally interested in strong Python engineers with BESS or energy experience who are willing to transition to Go. The right domain expertise, learning ability and hunger matter more than years on a resume. In this role, you’ll be a critical integration point between our automation systems and cloud platform, working closely with both our Senior TwinCAT Engineer and Cloud team to evolve our architecture. You Will • Develop applications running on the Capture Controller to handle energy optimization, state management and control logic • Communicate with TwinCAT via ADS (Automation Device Specification) to coordinate PLC operations and sensor data • Design and implement data schemas and APIs for reliable, bidirectional data exchange between the controller and cloud services • Architect a clean separation between real-time PLC functions and business logic in the controller application • Work closely with both the TwinCAT engineer on the OT side and the Cloud team on the IT side to define data contracts and integration points • Build robust error handling, logging and monitoring for production control systems We Expect You To • Have solid production experience in Go or Python. You’ve shipped code that matters and understand what can go wrong in production • Have strong systems-level thinking across state management, concurrency, real-time data handling and distributed systems • Have hands-on experience with energy systems, BESS or battery management. This is critical and the hard part to teach • Have experience with industr
