What are we looking for?
We are looking for a
BESS Engineer O&M,
who plays a critical role in ensuring the reliability, availability, and long-term performance of the company's Battery Energy Storage Systems (BESS) and Solar PV assets across LATAM. This position provides specialized technical support to field O&M teams, develops and standardizes maintenance processes, and drives continuous improvement initiatives oriented toward asset integrity, safety, risk mitigation, and generation and storage performance maximization.

What challenges will you face?

• Provide expert-level technical support to O&M teams in BESS and PV plants, balancing technical, safety, and financial aspects to ensure optimal asset performance.
• Lead and support failure investigations and Root Cause Analyses (RCA) for critical events in BESS systems (PCS, batteries, BMS) and PV plants (inverters, trackers).
• Develop, improve, and standardize maintenance procedures, engineering guidelines, and technical documentation for BESS and PV equipment.
• Enhance preventive and predictive maintenance plans, incorporating condition-based, reliability-centered, and risk-based strategies.
• nterface with OEMs (battery manufacturers, PCS suppliers, inverter OEMs, tracker providers, transformer OEMs, etc.) to resolve technical issues, review warranties, and implement corrective actions.
• Analyze performance data and plant diagnostics (alarms, trends, availability, state-of-charge behavior, degradation patterns, PR losses, etc.) and propose improvement actions.
• Support the implementation of digital and analytical models for failure detection, battery health assessment, thermal behavior, and PV performance deviation identification.
• Coordinate engineering evaluations and risk assessments related to asset condition, equipment failures, operational hazards, and lifecycle planning. Contribute to technical training and knowledge transfer for O&M field teams and service providers.
• Collaborate with Construction, Asset Management, HSE, and Digital Office teams to ensure engineering alignment throughout the asset lifecycle.
• Participate in the development and implementation of company standards for BESS commissioning, PV acceptance testing, safety protocols, and asset care.

What specific knowledge do you need?

• At least 4–7 years of experience in asset maintenance, reliability engineering, or technical operations in Solar PV, BESS, electrical substations, or power systems (MANDATORY)
• Bachelor's degree in Electrical, Electronics, Mechatronics, or related Engineering.
• Postgraduate studies in Power Systems, Renewables, Reliability Engineering, or Energy Storage are a plus
• Root Cause Analysis methodologies (RCA, 5 Whys, FMEA)
• Knowledge of standards (IEC, IEEE, ISO 55000)
• Strong understanding of maintenance engineering principles for inverter-based and energy storage technologies.

What does Atlas offer you?

• Belong to a multicultural, inclusive, and diverse environment. We are in the USA, Mexico, Brazil, Chile, Uruguay, Colombia, and Spain.
• Twenty work days of vacation (which you can take in advance without completing the year) and additional rest days for the end-of-the-year holidays.
• Other economic benefits include performance bonuses and food vouchers.
• We promote sports with our "In Motion" benefit.
• We promote Health and Life with our health and life insurance with high-level coverage.
