About Ossus Biorenewables
Ossus Biorenewables is India’s leading green hydrogen company, pioneering sustainable energy solutions through advanced bioreactor technology. With operational hydrogen plants across India, we’re accelerating the shift toward a cleaner, circular, and more energy-efficient world.
Role Summary
We’re looking for a Mechanical Design Engineer who can bring ideas to life — from concept to CAD to real-world systems. You’ll design, model, and prototype key mechanical components that drive our bioreactor-based hydrogen production systems.
If you’re passionate about designing sustainable technologies and want to see your work make a real-world impact, this role is for you.
What You’ll Do
- Develop detailed 3D models, assemblies, and technical drawings for process and reactor systems.
- Take ownership of designs from paper to computer to fabrication.
- Apply strong fundamentals in mechanics, dynamics, and load analysis to ensure robust and reliable performance.
- Collaborate with R&D, manufacturing, and operations teams to convert innovative designs into functional systems.
- Support simulations and structural validations where required.
- Optimize designs for manufacturability, efficiency, and scalability.
What We’re Looking For
2–4 years of experience in 3D modeling, assembly, and drafting.Hands-on proficiency in SolidWorks or Fusion 360.Solid understanding of mechanical engineering principles — statics, dynamics, and structural loads.Proven experience taking a design from concept to physical build.Good to Have :
Exposure to fluid dynamics, simulations (CFD / FEA), and manufacturing technologies.Experience in energy systems, bioreactors, and industrial equipment design is a plus.Why You’ll Love Working With Us
Direct impact : Work closely with the core founding team shaping India’s green hydrogen revolution.Flexible work hours – we focus on outcomes, not clock-ins.Competitive compensation aligned with your experience and expertise.Purpose-driven culture – every design you create contributes to a sustainable, cleaner planet.Growth & learning – exposure to R&D, prototyping, and real-world clean energy systems.
