The Junior Boiler Engineer supports the design, operation, inspection and maintenance of Heat Recovery Steam Generators (HRSG) and associated pressure parts. Under mentorship, you will help ensure safe, reliable steam generation by assisting with thermal assessments, pressure‐part integrity checks, and routine engineering tasks.
Design & Technical Support
Assist in preparing basic HRSG piping and pressure‐part layouts, isometrics and datasheets.
Support senior engineers in calculations (heat balance, pressure drop, flow rates) for steam cycle components.
Inspection & Integrity Monitoring
Aid in scheduling and performing visual inspections, thickness measurements, and NDE-prep (ultrasonic, dye‐penetrant) on HRSG tubes, drums, headers, and piping.
Record and log inspection data; flag deviations for senior review.
Maintenance & Troubleshooting Assistance
Help plan and coordinate minor maintenance tasks on economizers, superheaters, reheaters, and expansion joints.
Participate in root-cause investigations for leaks, corrosion or tube failures, gathering data and documenting findings.
Documentation & Compliance
Maintain up-to-date equipment files, mechanical integrity records, and vendor certificates for pressure parts.
Support Management of Change (MoC) processes for any design or material modifications.
Vendor & Spare Parts Coordination
Assist in preparing RFQs and reviewing datasheets for spare tubes, gaskets, fasteners and pressure-rated valves.
Track delivery status and quality of replacement parts.
Safety & Quality Assurance
Adhere to all HSE protocols (LOTO, confined space, high-temperature work) during inspections and maintenance.
Support QA/QC checklists and ensure compliance with ASME Section I & VIII requirements.
Learn to monitor stack temperatures, economizer ∆T, and steam superheat to optimize heat recovery.
Focus on maintaining tube thickness, header condition, and weld integrity to prevent high-pressure leaks.
Ensure precise recording of thickness readings, alignment checks, and pressure test results.
Help establish schedules for tube cleaning, deslagging, and boiler blowdown to maintain cycle efficiency.
Embed safe work practices in all engineering tasks and uphold boiler code requirements (ASME, TEMA).
Education: Bachelor’s Degree in Mechanical or Thermal Engineering
Experience: 0–2 years; internships or co-op rotations in boiler or steam systems preferred
Certifications: Boiler operator familiarization (optional), basic NDE awareness (beneficial)
Fundamental understanding of heat-recovery steam generators and pressure-part design
Basic proficiency with engineering tools (FEA basics, CAD, HYSYS or similar)
Strong attention to detail in data collection and documentation
Good communication and teamwork skills in a multidisciplinary maintenance environment
Eagerness to learn industry codes and inspection techniques
On-site role in boiler house or HRSG areas; exposure to high heat, steam, and elevated platforms
Shift work and participation in outages/shutdowns may be required
Mandatory use of PPE and strict adherence to plant safety procedures
