Driving Quality: QA Automation Engineer with Web, Mobile & API Expertise

HydroNeo is a fast-growing, international startup focusing on Smart Farming solutions for the global aquaculture industry. Our vision is to expand our Smart Farm Management System — already the market leader in Thailand — into the HydroNeo Aquaculture Super App, serving everything farmers and the industry need. We are backed by leading Thai and international investors, BOI-promoted, and have a dynamic team of 30+ in Bangkok.

​Are you ready to shape the future of aquaculture and make a real difference for shrimp and fish farmers worldwide? As our next QA Automation Engineer, you won’t just write code, you’ll help redefine an entire industry. This is not your typical 9-to-6 job. Here, your ideas matter, your voice is heard, and your code directly impacts real people and sustainable food production.

​We’re looking for a developer who’s hungry to grow, passionate about meaningful work, and excited to build something that truly matters. You’ll have the freedom to propose ideas, experiment, validate your solutions with data, and see your work come to life in the hands of our users.

​To kick things off and if you want, you have the chance to immerse yourself in our mission by working in our office in Bangkok for a few days before helping us to launch HydroNeo Indonesia in Surabaya, where your impact will span across borders and markets.

​If you want to build, learn, and make a difference far beyond the average dev job, we want to meet you!
