  • Direct implementation of real-time and embedded control solutions; select and guide the use of PLC, FPGA, and other real-time platforms while balancing performance, reliability, safety, and cost trade-offs.
  • Work with system integrators, electrical engineering, cabinet builders, and technicians to specify, design, review, test, install, and commission control cabinet hardware and field devices.
  • Work with the software team to architect and deliver integrated SCADA, HMI, and data systems for alarms, logging, historian, analytics, data reduction, and dashboards, ensuring scalability and high performance.
  • Orchestrate system integration across complex subsystems and teams; define observability, logging, and diagnostic strategies; lead root-cause investigations and post-mortem studies of active systems; and contribute lessons learned to continuous availability improvement.
  • Shape system-level requirements, documentation, and validation approaches, including design specifications, interfaces, and test strategies for reliability, safety, and long-term maintainability.
  • Coach and mentor senior and junior engineers, identify capability gaps, grow technical capabilities in key skill areas, and champion best practices for software engineering, testing, quality, and ways of working within the controls team and beyond.
Desired Qualifications
  • Deep experience with PLC programming in ST (IEC 61131-3), Beckhoff PLCs and TwinCAT system design and architecture, and multi-PLC distributed control.
  • SCADA, especially Ignition, and/or experience designing and deploying SCADA systems and applying cross-site HMI standards for large-scale, complex systems.
  • Experience with embedded or real-time systems, including FPGAs, RTOS, microcontrollers, and robotics, as well as platform selection and long-term maintainability strategies.
  • LabVIEW architect-level certification (CLA), focused on FPGA and embedded targets.
  • Experience with complex scientific equipment or large-scale facilities, including diagnostics, vacuum systems, motion platforms, and safety interlocks.
  • Experience with image processing and machine vision, motion control and robotics, high-precision stepper/piezo systems, and encoders.

About the company

Focused Energy pursues commercial fusion power using laser-driven inertial confinement fusion (ICF). Laser pulses compress tiny fuel pellets to the extreme conditions needed for fusion, with the aim of producing carbon-free electricity in a controllable, earthbound setting. The company combines expertise in high-energy lasers, plasma physics, materials science, and power-plant engineering to design lasers, optimize fuel, and build integrated prototypes with scientific and industrial partners to scale toward power generation. Their goal is to achieve commercial readiness in the coming decades and provide safe, abundant carbon-free electricity as part of the global energy mix.

What believers are saying

  • RWE’s Biblis site gives Focused Energy existing power-plant infrastructure and utility expertise.
  • University of Rochester’s $6.9 million LLE collaboration directly attacks laser-plasma instability problems.
  • SPRIND, EIC Fund, and RWE backstop execution through 2026 and beyond.

What critics are saying

  • NIF’s 2026 pace still implies Focused Energy must jump from 400 annual shots to 10 per second.
  • Laser-plasma instabilities and pellet manufacturing remain unsolved blockers for commercial fusion.
  • Failure at Biblis or Lighthouse would strand hundreds of millions and kill the company.

What makes Focused unique

  • Focused Energy won Germany’s 2026 Biblis national laser-fusion hub designation.
  • Its $240 million Series A closed May 2026, the industry’s largest fully secured round.
  • Amplitude partnership funds two high-repetition lasers for its San Francisco development facility.

German nuclear plant repurposed for laser fusion electricity production after Focused Energy raises $260M

A German company developing laser fusion technology has secured significant funding and acquired a decommissioned nuclear power plant to advance its work. Focused Energy, which specialises in a variant called inertial confinement fusion, has completed a Series A funding round worth DKK 1.7 billion. The company plans to use the shuttered German nuclear power plant as a facility for producing electricity from laser fusion. Fusion power holds enormous potential as an energy source but remains an unsolved challenge for humanity. Focused Energy is among several companies working to make fusion power commercially viable. The acquisition of the former nuclear facility provides the company with infrastructure to develop and test its fusion technology.

German startups eye US move for funding access and higher valuations

Many European startups consider relocating to the United States following successful early-stage funding from regional investors. The motivations extend beyond market access to include a broader investor base, easier access to venture capital financing, higher valuations and the Nasdaq technology exchange as a potential exit channel. However, one crucial factor often drives the decision: investors frequently require a US legal structure. This requirement can be decisive in determining whether startups make the transatlantic move. The article is a guest contribution by Henning Bloss, Jörn Hirschmann and Ansgar Simon, examining the complexities and considerations involved in relocating a startup to America. For European founders, understanding these requirements and opportunities is essential when planning international expansion and future funding rounds.
