Senior Software and Algorithm Engineer

Role Description

As a member of the OpenBlue AI team, the Senior Algorithm Engineer leads development and maintenance of the numerical algorithms that underpin the CUPO solution. You will:

• Improve existing algorithms to cover new equipment types and configurations or enhance optimization performance.
• Work closely with site and modeling teams to understand reported issues, identify fixes, and resolve bugs in the algorithm code.
• Contribute to development of other autonomous buildings capabilities, including optimization of airside equipment.

We prefer to have this individual reside in Eastern time zone, but this is a remote opportunity.

Qualifications

• Bachelor's degree in mechanical, electrical, chemical, or other engineering field.
• Familiarity with system-of-equations solvers for interconnected HVAC plant equipment.
• Proficiency in MATLAB for numerical algorithm development and debugging.
• Experience with Python and scientific computing libraries (NumPy, SciPy) for data processing and algorithm implementation.
• Familiarity with optimal-control strategies (e.g., dynamic programming, model-predictive control, reinforcement learning).

Requirements

• Eight years of experience in applied engineering.
• Excellent verbal and written communication skills.
• Experience with Python and data-science packages (Pandas, Scikit-Learn, etc.).
• Experience reading and writing C# code.
• Experience modeling HVAC equipment (chillers, cooling towers, AHUs, etc.).
• Familiarity with mass and energy balances and thermodynamics.
• Familiarity with numerical optimization (e.g., mixed-integer linear/nonlinear programming).
• Proficiency in optimal-control strategies (e.g., dynamic programming, model-predictive control, reinforcement learning).
• Experience writing and debugging numerical simulations.
• Experience with JIRA.

Benefits

• Competitive salary.
• Paid vacation/holidays/sick time.
• Comprehensive benefits package including 401K, medical, dental, and vision care.
• On-the-job/cross-training opportunities.
• Encouraging and collaborative team environment.
• Dedication to safety through our Zero Harm policy.
