Position Description :

FlexGen is building the future of sustainable energy infrastructure—where datacenters aren’t just power consumers, but smart, responsive participants in a more resilient grid. As part of our energy storage platform team, you’ll engineer control systems that make datacenters more efficient, reliable, and sustainable.

We're looking for a systems-minded engineer to develop real-time control applications that orchestrate power routing, thermal systems, and auxiliary infrastructure within our energy-integrated datacenter platform. This role is about high-performance control on Linux-based systems, where milliseconds matter and uptime is everything.

Datacenters are critical infrastructure—and they’re also some of the world’s largest energy users. At FlexGen, we're changing the equation. Our HybridOS platform helps facilities operate more sustainably and intelligently, using energy storage to reduce peak demand, support grid reliability, and conserve natural resources. If you thrive at the intersection of physical systems and software—and want to help shape the datacenter of the future—we want to hear from you.

Major Job Responsibilities :

• Develop real-time applications that control power routing, thermal management, and system-level coordination
• Design fault-tolerant software architectures for auxiliary system control with sub-second response times
• Integrate FlexGen's energy storage and HybridOS platform into new datacenter product lines
• Interface with HVAC systems, sensors, and power hardware to monitor and optimize infrastructure performance
• Support commissioning and test of new installations—on-site or remotely—with an eye on uptime and efficiency
• Collaborate with power systems and software teams to align control logic with energy market participation and operational goals
• Deliver solutions that help reduce energy and water consumption while improving overall system resilience

Position Requirements :

Proficiency in C++, Go, or similar systems-level languages
