Bangkok Private Investigators is expanding. We’re looking for reliable freelance field operatives in Bangkok, Pattaya, Phuket, Chiang Mai and major Isaan cities (Khon Kaen, Udon Thani, Korat, etc.). If you’re already living in Thailand and searching for part-time work that pays per assignment, read on.

Why Work With Us?

• Flexible schedule – accept or decline cases around your other commitments.
• Project-based pay – competitive day rates plus expenses; a useful side income.
• Varied assignments – from discreet surveillance to address verification.
• No previous PI experience needed – the right attitude and reliability matter most.
• Local autonomy – work in the area you know best, using your own contacts and knowledge.

Typical Tasks

• Static and mobile surveillance on foot, motorbike or by car.
• Capturing time-stamped photos and video of subjects and locations (great for anyone seeking part-time photography work in Thailand).
• Confirming addresses, workplaces and accommodation.
• Discreetly interviewing neighbours, hotel staff or other sources.
• Gathering open-source intelligence (social media, public records, local chatter).

Who We’re Looking For

You must already be based in Thailand. Ideal candidates tick several of the boxes below:

• Fluent English; Thai language skills are a plus.
• Resident of—or able to reach quickly—Bangkok, Pattaya, Phuket, Chiang Mai or an Isaan hub.
• Comfortable spending hours in the field in heat, nightlife areas or rural backroads.
• Access to reliable transport (motorbike or car) with a valid Thai licence.
• Owns a capable camera or long-zoom smartphone; a drone is a bonus.
• Background in private investigation, security, journalism, photography or hospitality welcome but not essential.
• Discreet, observant, patient and punctual—our reputation depends on your professionalism.

Equipment & Resources

You don’t need a Hollywood spy kit. A modern phone, power bank and patience often do the job. Let us know if you also have:

• DSLR or mirrorless camera with zoom lens.
• Action cam or body-worn camera.
• Drone capable of 4K video.
• Night-vision or low-light capability.
• Local contacts (hotel staff, taxi drivers, bar owners, estate agents). Mention the type only; we’ll talk specifics privately.

Availability & Commitment

• Most gigs are part-time: an afternoon tail in Bangkok, a weekend hotel watch in Phuket, a one-day address check in Udon Thani.
• We work around your main job or studies, provided you respond quickly, arrive on time and deliver clear reports.

How to Apply

Complete our contact form and include:

1. Your full name, age and nationality.
2. Where you live in Thailand and how long you’ve been here.
3. Current employment status or main source of income.
4. Availability (days/evenings, weekdays/weekends).
5. Transport you own (bike, car) and any camera/drone gear.
6. Relevant skills—surveillance, photography, report writing, Thai language, etc.
7. Any PI or related experience (if applicable).

We’ll review and, if you look like a fit, arrange a brief call. Successful applicants start on small tasks and grow into more complex cases.
