What is a cleantech startup?

A cleantech startup is a new or early-stage company focused on developing technologies, products, or services that help reduce environmental impact, improve energy efficiency, or promote sustainable resource use. These startups often work in sectors such as renewable energy, energy storage, water purification, waste management, and sustainable transportation. Their goal is to address environmental challenges while building commercially viable businesses. Cleantech startups are important drivers of innovation in the transition to a more sustainable and low-carbon economy.

What are the key skills and qualifications needed to thrive in a cleantech startup, and why are they important?

To thrive in a cleantech startup, you need a solid background in environmental science, engineering, or business, often supported by relevant degrees or experience in sustainability. Familiarity with clean energy technologies, data analytics tools, and project management systems is typically required. Creative problem-solving, adaptability, and strong teamwork skills help individuals excel in the fast-evolving startup environment. These competencies drive innovation, facilitate rapid growth, and help startups effectively tackle pressing environmental challenges.

What are some common challenges faced when working at a cleantech startup, and how can job seekers prepare for them?

Working at a cleantech startup often means adapting to a fast-paced, dynamic environment where priorities can shift quickly as the company scales and innovates. Common challenges include limited resources, the need to wear multiple hats, and navigating regulatory complexities unique to clean technology. To succeed, job seekers should be comfortable with ambiguity, proactive in problem-solving, and passionate about sustainability. Building cross-functional communication skills and staying current with industry trends can also help you thrive in this collaborative setting.

Job description

Position Description: This is an extraordinary opportunity to come in at the ground floor of a fast growing, ultra-high impact CleanTech startup. We at Blue Frontier are racing to solve arguably the biggest sustainability problem in the world using disruptive technology and business models. Air conditioning is the fastest growing use of electricity in the US and globally. If present trends continue, by 2050 air conditioning electricity consumption will be bigger than the combined electricity consumption of China and India today!Blue Frontiers AC system combines dew-point-style sensible cooling with liquid desiccant dehumidification to reduce electricity use by up to 90%. The desiccant is recharged and stored when electricity is the lowest cost or cleanest, and later used to deliver cooling when electricity is costly or derived from non-renewable sources. These features enable our system to solve an array of todays largest sustainability problems from the Duck Curve to peak load management, from humidity control to integration of intermittent renewable resources.
Working in the Product Development department and reporting to the VP of Product Development, the Mechanical Design Engineer will implement engineering design solutions and processes that will enhance the performance, cost, reliability, manufacturability, durability, and quality of our systems.
