Our hope is for this person to quickly become a technical leader in energy modeling and building science.


  • Software development to support energy-related software improvements, including:
    • Enhancement and maintenance of the Ekotrope energy simulation engine.  For example, improving the accuracy of heat pump and air conditioner hourly performance models.

    • Contributions to EnergyPlus, DOE2, CBECC or other public energy simulation models.
    • Active development on other proprietary energy modeling software tools.
  • Significant software development experience.
    • Java fluency is preferred (our stack is mostly Java), but other object oriented programming can suffice.
  • Strong verbal and written communication skills, both technical and interpersonal
  • Passion for growth and learning
  • At least a Bachelor’s degree in an engineering discipline, with coursework in thermodynamics
  • Remote candidates are welcome, Boston candidates will be preferred.

About Us

Ekotrope is a customer-centric software company that believes our success is predicated on our customers’ success. We run the most widely used Home Energy Rating Software which is used on about 1 in 4 of new homes built in the US each year.  Our clients for this product are home energy raters who work with home builders to help design more energy efficient homes and then inspect and certify those homes.  We also help utilities run their energy efficiency programs more effectively.  To date, most of our work has been focused on low-rise single and multi-family homes but we are now expanding to provide solutions for existing homes and larger multi-family buildings.

Our software development team consists of 11 full time engineers.  We employ a modified Scrum framework.  We have weekly team planning, demo, and retrospective meetings and daily Scrums.  We have short development cycles and a tight customer feedback loop.  We promote transparency, respect, self-improvement, and fulfillment.

Ekotrope offers a full benefits package, including comprehensive health insurance and a 401K program.  We are currently all working from home but will be looking for a new office in Boston, likely the Downtown Crossing area (blocks from all of the subway/T lines, commuter rail and buses).

This Company is an equal opportunity employer, and selects individuals best matched for the job based upon job-related qualifications regardless of race, religion, color, creed, sex, sexual orientation, age, ancestry, national origin, gender identity, genetic information, disability, pregnancy, veteran or military status or any other status or characteristic protected by law.
