Key Responsibilities
* Lead technically the most complex industrial refrigeration projects (NH3 focus) through design, build coordination and commissioning; ensure first‑time‑right start‑up and acceptance.
* Act as Technical Authority across the portfolio: provide design reviews, risk assessments, and approvals/waivers for critical decisions and changes.
* Support project engineers and project managers with practical field know‑how: equipment selection, P&IDs, sizing, piping concepts, defrost strategy, oil management, safety functions, and controls concepts.
* Provide operational escalation support (post‑commissioning): assist operations/service teams in diagnosing and resolving complex plant issues; drive structured root‑cause analysis (RCA).
* Mentor and coach younger colleagues through reviews, on‑the‑job training, and short technical sessions; build capability across the team.
* Represent Johnson Controls in technical discussions with customers, contractors, and vendors; support FAT/SAT and supplier clarifications.
Required Qualifications
* Extensive hands‑on experience in industrial refrigeration with a strong focus on NH3; ideally 20+ years (depth and relevance matter most).
* Proven ability to deliver independently: design decisions, commissioning/start‑up troubleshooting, and complex fault finding in operating plants.
* Strong ability to read and challenge P&IDs and technical documentation; practical understanding of system behavior and failure modes.
* No formal degree required; vocational/technician background or engineering education are both acceptable—proven experience is key.
* Experience with natural refrigerants, especially ammonia, is a strong plus.
* Language: fluent in English or German; the other language is a plus.
