Principal Power System Engineer

Short company description

At AECOM, we believe infrastructure creates opportunity for everyone – uplifting communities, improving access and sustaining our planet.
We’re committed to managing our business with the upmost responsibility and to always strive for better — be that reducing emissions, creating social value or diversifying our senior leadership and workforce.

We understand both the urgency of the challenges facing our society and our responsibility to act in an impactful and enduring way. We’re leading the change towards a more sustainable and equitable future, partnering with those who want to make a positive difference in the world.

We’re listening to clients and the communities we serve in order to improve lives and livelihoods, and to create sustainable legacies for generations to come.

Thinking without limits is what keeps us at the vanguard. Ideas have no borders, and this ethos is embedded in our culture. The full scope of our global expertise is available to anyone who needs it, wherever they are based.

We’re trusted advisors — planners, designers, engineers, consultants and program and construction managers — delivering professional services spanning cities, transportation, buildings, water, new energy, and the environment. Working throughout the project lifecycle, we’re one team driven by a common purpose to deliver a better world.

Our History

AECOM launched when a handful of employees from design and engineering companies shared a dream of creating an industry-leading firm dedicated to delivering a better world.

We became an independent company formed by the merger of five entities. While our official founding was in 1990, many of our predecessor firms had distinguished histories dating back more than 120 years.

Since then, more than 50 companies have joined us and, in 2007, we became a publicly traded company on the New York Stock Exchange.

Requirements

Mandatory Qualifications:

- Education: Bachelor’s degree in Electrical Engineering;
- Experience: Minimum 5 years of experience in power system design, analysis, or construction within transmission and distribution networks;
- Technical Expertise: Demonstrated hands-on experience with PSCAD and PowerFactory for grid modeling, dynamic simulations, and renewable interconnection studies;
- Skills: Strong analytical and problem-solving abilities, effective communication, teamwork, and a solid understanding of electrical and grid principles relevant to transmission substations and power networks.

Nice to Have:

- Prior experience with advanced power system studies related to grid connection (e.g., using ETAP, PSSE, SKM and others);
- Experience preparing technical study reports for renewable energy grid connection projects, transient stability studies;
- Knowledge of protection coordination;
- Background in technical consulting or acting as a subject-matter expert;
- Familiarity with International Standards (IEC, IEEE, ANSI, British and Australian Standards).

Responsibilities

The Principal Power System Engineer is responsible for leading the design, analysis, and optimization of complex transmission and distribution networks, as well as renewable energy plants. This role ensures the safety, reliability, and efficiency of the power grid through advanced engineering studies, innovative technical solutions, and compliance with international standards. Expertise in PSCAD and DIgSILENT PowerFactory is essential for performing in-depth grid simulations, renewable integration studies, and network modelling.

Key Responsibilities:

System Design and Engineering:
- Design HV/MV power system infrastructure, including substations, transformers studies and reports (harmonics, power quality studies, thermal ratings and loss evaluation) and renewable energy grid connections;
- Perform studies: load flow, short-circuit, arc-flash, and stability analysis;
- Ensure designs meet technical, client, and regulatory standards.

Insulation Coordination Studies:
- Develop a detailed model of the substation using PSCAD/Digsilent/ ETAP software;
- Perform studies: transformer energization, transient overvoltage, switching overvoltage, fast font overvoltage;
- Ensure designs meet technical, client, and regulatory standards;
- Provide recommendations so that the substation design meets the requirements for Insulation Coordination.

Grid Compliance Studies for renewables:
- Develop a detailed model of the plant using PSCAD/Powerfactory software;
- Perform steady state studies: load flow, short circuit, reactive power capability, network losses, power quality etc;
- Perform steady dynamic (RMS) and transient (EMT) studies to check the power plant’s response: voltage and frequency stability, fault ride through, change in voltage angle, sub synchronous oscillations etc.;
- Check to see if the plant’s designs meet technical and regulatory standards.

Project Management:
- Plan and coordinate T&D project activities and schedules;
- Collaborate with teams, contractors, and Aecom clients;
- Prepare reports, estimates, and resource plans for the team.

Compliance and Standards:
- Ensure alignment with IEC, IEEE, NERC, and regional codes;
- Follow industry best practices and promote safety and quality.

Documentation and Reporting:
- Prepare technical documents, drawings, calculation sheets and study reports;
- Present findings and recommendations to client meetings and Aecom Lead offices.
