About the role:

India is building a green hydrogen industry that, in most respects, does not have a rulebook yet. Someone has to write it while the plants are already being built. That is this job.

Hygenco is a pure-play green hydrogen company, building, owning, and operating some of Indias first commercial-scale green hydrogen plants. We recently closed a $105 million Series B round from IFC, Siemens, and Fullerton, alongside continued backing from existing investor Neev II Fund. You will own the engineering judgement behind every plant along that path, working alongside the team that develops our core process technology and the team that builds our plants physically, but accountable for something distinct from both: making sure each specific plant is engineered correctly, safely, and built to last.

The role:

As Head of Plant Engineering, you hold Design Authority for every plant we build, the final call that a plants engineering is correct and safe, for its entire life, not just through construction. You will lead a multidisciplinary team across six engineering disciplines, chair the design effort on every project from concept to commissioning, and help build the technical standards your own engineering will run on for years to come.

What you will own:

- Design Authority across every plant we build, holding for the plants entire life, not just through construction.

- A multidisciplinary engineering team spanning process, piping and civil, mechanical, controls and instrumentation, electrical, and process safety, one integrated design effort per project, that you personally lead from concept to final sign-off.

- Technical qualification of every outside engineering firm we work with, building a pool of trusted partners so this is not repeated from scratch each time.

- Our technical standards and equipment catalogue, built from the ground up, a direct outcome of the real plants you are already building, not a side project.

- The engineering platform that turns a verified design into working drawings and documentation, fast.

- The safety case for every plant: process hazard studies built into every design from day one, and your own sign-off before any gas is introduced.

Why this role, and why now:

Most senior engineering roles ask you to operate inside a rulebook someone else already wrote. This one asks you to write it, while real plants, real capital, and real safety cases are already in motion. In your first year, you will qualify the engineering partners we work with, adopt and interpret international and Indian codes for situations we do not yet have our own standard for, and turn what those first live projects prove out into the standards the next ten plants will run on.

What we are looking for:

- Deep, hands-on engineering judgement, not a job title.

- Fifteen to twenty years in process, chemical, or mechanical engineering, with real independent design-authority or owners-engineer experience, not only design production inside an EPC or engineering-services firm.

- Genuine comfort with process safety (HAZOP, LOPA, SIL), and with making a binding engineering call when the standard you would like to point to does not exist yet.

- A track record of holding an engineering line under real commercial or schedule pressure, with enough fluency in cost and schedule consequence to be taken seriously by the people who feel that pressure hardest.

- A background in industrial gases is a strong plus, but we are just as open to refining, petrochemicals, fertilisers, hydrogen or ammonia EPC, or any comparably hazardous, safety-critical process industry.

- Comfortable directing technical teams and evaluating modern engineering tools on their own merits.
