I am writing to express my interest in the Calibration Engineer position. I have been working as a Calibration Engineer with BSRIA since July 2023, where I have gained extensive hands‑on experience calibrating a wide range of instrumentation, ensuring compliance with UKAS standards, and supporting clients across HVAC, environmental, and building performance sectors. During my time at BSRIA, I have carried out precise calibration of temperature, pressure, airflow, electrical, and humidity equipment, consistently meeting strict accuracy requirements and turnaround targets. I am confident working within ISO 17025 frameworks, producing clear calibration reports, and maintaining meticulous documentation to support audit readiness. My role has also involved troubleshooting equipment issues, advising clients on best practice, and contributing to continuous improvement initiatives within the laboratory. I take pride in delivering reliable, high‑quality calibration work and maintaining a strong focus on safety, consistency, and customer satisfaction. My experience in a fast‑paced, technical environment has strengthened my problem‑solving skills, attention to detail, and ability to work both independently and as part of a collaborative engineering team. I am enthusiastic about the opportunity to bring my calibration expertise, technical capability, and commitment to quality to your organisation. I would welcome the chance to discuss how my experience aligns with your requirements. Thank you for considering my application. Sincerely, Tanvir Hossain
