About SmartAir Bangladesh

Smart Air Bangladesh is a social business on a mission: making clean air accessible to everyone in Bangladesh through affordable technology, transparent data, and meaningful public engagement. They design and distribute high-quality, low-cost air purifiers and deploy air quality monitoring networks that put real data into the hands of communities, researchers, and policymakers. Founded as part of the global Smart Air network, the Dhaka team works lean, moves fast, and holds itself to the same standard it asks of the air: clear and honest.

About The Role

As part of a grant-funded project, Smart Air Bangladesh is expanding its air quality sensor network across Dhaka. The IoT Engineer plays a critical role in this expansion, holding primary responsibility for the technical installation and operational integrity of a hybrid air pollution monitoring network.

This involves leading physical installations at key project sites, managing mounting, power, and connectivity (WiFi and cellular SIM), configuring data transmission, verifying cloud connectivity to OpenAQ, and managing a scheduled maintenance programme including sensor cleaning and firmware updates. The role also includes remote data quality monitoring, identifying sensor drift against reference baselines, and providing technical certification for data provenance used as legal evidence.

KEY RESPONSIBILITIES

- Deploy and commission air quality sensors at assigned sites, ensuring each installation is fully operational, correctly oriented, and connected to the data network within agreed timelines

- Maintain a rigorous calibration schedule so that sensor accuracy is validated against reference instruments on a rolling basis and drift is corrected before it affects data quality

- Diagnose and resolve equipment faults including power issues, sensor failures, and connectivity drops during site visits, minimising data gaps and downtime

- Clean, validate, and flag anomalous data streams daily; deliver a weekly data-quality report that enables the team to act on findings with confidence

- Integrate sensor nodes via Wi-Fi and GSM protocols into cloud-based dashboards, ensuring seamless data flow and remote-monitoring capability

- Maintain accurate maintenance logs, calibration records, and site-condition notes so that every decision is traceable and audit-ready

- Proactively flag potential equipment failures before they result in data gaps and recommend preventive action to the Operations Manager

- Work in close partnership with the Sensor Technician to coordinate field interventions, schedule site visits, and ensure seamless physical and technical execution of the monitoring network

SKILLS AND QUALIFICATIONS

- Bachelor's degree in Computer Science and Engineering, Electrical and Electronic Engineering, Mechanical Engineering, Civil Engineering, Software Engineering, or a related field

- 2-3 years of hands-on experience in field instrumentation, environmental monitoring, or IoT hardware maintenance

- Working knowledge of electrochemical sensors and laser-based particulate sensors, including typical failure modes and calibration requirements

- Proficient in Excel and at least one scripting or data-analysis tool for data cleaning, validation, and visualisation

- Familiar with IoT connectivity protocols (Wi-Fi, GSM) and basic cloud data pipeline concepts

- Physically fit and willing to travel extensively throughout Dhaka via motorcycle or public transport

- Comfortable working in varied field conditions, including installing sensors on rooftops, balconies, and outdoor sites in all weather, in compliance with OHS protocols

- Detail-oriented with a structured approach to record-keeping; a task is not done until the log entry is complete

- Fluency in Bengali required; advanced English speaking and writing for technical reporting is required

COMPENSATION AND BENEFITS

Monthly Salary: BDT 50,000 - 55,000 (based on experience and qualifications)

- Mobile bill and office lunch facilities

- Provident fund

- Medical allowance

- Festival bonus: 2x per year

- Employee discount on Smart Air air purifiers and filters

- Paid annual leave
