About KULT FARM

KULT FARM makes a true and natural alternative to meat from mycelium solid state fermentation. As a venture-backed business, we are pioneering this approach.

Our mission is to foster the world’s transition to a sustainable food system- without asking consumers to compromise on taste, texture, or price.

Our planet cannot sustain our current food system; therefore, we believe in producing exceptional alternative products to remove the current strain on our environment and ensure food security for our future ever-growing population.

This is your opportunity to have an impact on our planet and experience a startup in its earliest days .

Tasks This role sits at the intersection of bioprocess engineering, indoor farming, and applied microbiology, and is critical to translating lab-scale fermentation into robust, scalable, and economically viable production systems.

We are looking for a responsible, organised individual with a practical approach to work on scaling our solid-state fermentation plant.

We are not looking for scientists.

Key responsibilities

Fermentation

Design and implement fermentation infrastructure, including incubation environments, airflow systems, humidity control, and thermal management.

Develop fermentation processes, including inoculation strategies, substrate conditioning and harvest protocols.

Monitor and control critical process parameters (moisture, temperature, airflow, O₂/CO₂, pH where relevant) to hit target yields, product specs and consistency

Indoor farming systems

Co‑design and operate our indoor farming infrastructure: trays,



racks, climate rooms, sensors, air handling, humidification and lighting (where applicable).

Collaborate with mechanical/electrical partners on layout, utilities and ergonomics for scalable farm modules (from pilot to pre‑industrial).

Ensure high uptime and robust operation of equipment through basic maintenance, troubleshooting and coordination with external technicians.

Process engineering

Integration into and process engineering on the full production chain.

Collaborate closely with R&D; to translate experimental protocols into scalable, repeatable processes.

Scale‑up and industrialisation

Translate pilot learnings into engineering inputs for larger‑scale facilities (mass balances, capacity calculations, throughput models).

Facility layout planning and equipment selection for pilot scale to industrial setup.

Requirements

Degree in Bioprocess / Chemical / Biochemical / Agricultural / Electrical Engineering, Biotechnology, Food or Environmental Engineering, or similar.

At least 2 years proven hands‑on experience in fermentation, controlled-environment agriculture, mushroom farming, vertical / indoor farming, or similar process industries.





Proven experience operating and troubleshooting pilot‑ or production‑scale systems (bioreactors, climate rooms, indoor farms, or analogous equipment).

Solid understanding of mass and energy balances, heat and mass transfer, and basic process control concepts.

Comfortable working physically in a pilot production plant environment (cleaning, handling trays, doing measurements) as part of the daily work.

Working proficiency in English; Spanish and/or German is a plus.

A track record of willingness to learn, adapt, get stuff done, and be proactive

Independence and strong sense of ownership for tasks

Benefits

You will work in a cross-disciplinary Production team with food technologists, biotechnologists, microbiologists, engineers at a cutting‑edge technology.

Trans‑disciplinarity at its peak: we believe invention only happens when you connect dots that are seemingly far apart.

A high‑impact, ambitious startup environment with the ability to learn and grow alongside the company The opportunity to work on groundbreaking technology and make a true impact on the environment and our food system A fun, versátil, and rewarding environment where you can have the ability to thrive as a person
