A Sustainability Startup job involves working for a new or growing company focused on environmental, social, and economic sustainability. These roles can vary widely, from developing eco-friendly products to creating sustainable business strategies. Employees may work on projects related to renewable energy, circular economy solutions, or carbon footprint reduction. Since startups are fast-paced, employees often wear multiple hats and contribute to different areas of the business. The goal is to drive innovation that supports a more sustainable future while ensuring the company’s growth and success.

To thrive in a sustainability startup, you need a strong understanding of environmental science, business development, and project management, typically supported by a relevant degree or startup experience. Familiarity with sustainability frameworks (such as B Corp or LEED certification), data analytics tools, and carbon accounting software is highly valued. Creative problem-solving, adaptability, and effective communication are essential soft skills for driving innovative solutions and building stakeholder relationships. These skills are critical for navigating the fast-paced, impact-driven environment of sustainability startups and achieving meaningful results.

What are some common challenges faced when working at a sustainability startup?

Working at a sustainability startup often involves operating in a fast-changing environment where priorities and strategies can shift quickly. Team members may need to wear multiple hats, balancing core responsibilities with areas such as fundraising, marketing, and stakeholder engagement. Additionally, establishing measurable impact and scaling environmentally focused solutions can present unique challenges that require both creativity and resilience. However, these dynamics offer valuable opportunities for professional growth and meaningful collaboration with passionate individuals who are committed to driving positive change.

How do I start a career in sustainability startup?

  • Support project development and client relationships: Support scope, schedule, fee development, negotiation, staffing, and service expansion opportunities with existing clients.
  • Collaborate across KJ: Partner with multidisciplinary teams and travel to client sites, project locations, and KJ offices as needed.

What Makes This Role Different
  • Technical influence: Shape solutions for complex industrial water and wastewater challenges where strong process design decisions improve efficiency, reliability, and long-term client outcomes.
  • Full lifecycle impact: Influence projects from early planning and alternatives analysis through design, construction, commissioning, and startup, creating continuity between strategy and execution.
  • Practice growth: Support client relationships, strengthen KJ's industrial water and wastewater capabilities, and contribute to sustainable, high-impact project delivery.

What You Bring
  • Technical leadership and process knowledge: Ability to guide process design decisions, advise project teams, and apply industrial water and wastewater treatment knowledge to complex technical challenges.
  • Project delivery perspective: Understanding of how technical decisions support successful delivery across planning, design, construction, commissioning, and startup.
  • Client and team communication: Ability to collaborate clearly with clients, multidisciplinary teams, and internal stakeholders.
  • Analytical approach: Ability to evaluate options, interpret testing results, and recommend solutions that balance performance, cost, schedule, constructability, and sustainability.

Qualifications
  • Education: Bachelor's or Master's degree in Chemical, Environmental, Mechanical, Civil, or a related engineering field.
  • Experience: 10 years of engineering experience in investigation, planning, design, construction, and commissioning, including relevant consulting experience.
  • Project management: Experience supporting or leading scope, schedule, and budget oversight for engineering projects.
  • Market sector experience: Experience applying process design solutions across sectors such as mining and metals, pulp and paper, food and beverage, data centers, pharmaceuticals, chemicals, or similar industrial environments.
  • Licensure: Professional Engineer (PE) license in Colorado required.
  • Travel: Ability to travel to client and project sites as needed for client visits, meetings, project coordination, and collaboration with other KJ offices.
  • Additional preferred qualifications: Familiarity with computer-aided drafting and design tools such as AutoCAD, BlueBeam, Revit, or similar platforms.

Kennedy Jenks supports a healthy work-life balance and utilizes a hybrid model of home and office work, with a minimum of two days per week in the office. This approach empowers our people to thrive, collaborate, and do their best work.
Salary range for this position is anticipated to be $140,000 to $200,000, and may vary based upon education, experience, qualifications, licensure/certifications, and geographic location.
