Lead Developer [PHP/Python]

Parklink Limited seeks a skilled, motivated candidate to fill the position of remote Lead Technician fluent in Python and PHP, who loves the challenges of high-availabilty SaaS and working with hardware.

About us

Parklink Development Limited provides RFID duplication devices to locksmiths and security professionals.

Our flagship product is ‘Rebadge’. It’s a patented machine that duplicates RFID badges for customers. Before Rebadge, it was impossible to duplicate consumer RFID badges. Since the launch of Rebadge, literally hundreds of thousands of people have been able to make copies of their badges, and the number increases every day.

Each machine is an embedded linux system running Python + Qt, and tethered online.
Supporting the machines is a RESTful API (CakePHP).
There is also a full back-office system for client management, machine management, billing, etc.

We’ve got over 2,000 machines online (Check out our coverage map here:

We’ve recently expanded into Australian and US markets. With this growth comes new challenges, and this is where your expertise comes in.

The team currently consists of three staff - the founding partners operating in the roles of CTO and COO, and a technical support role. The succesful candidate would be the fourth member on the team. The company structure is based in Hong Kong, but the partners are EU based.

We are a highly optimised / lean company. The successful candidate will have the ability to work autonomously on a constantly evolving product and rapidly expanding client base. You will work on a real product that is used by thousands of people daily. 

Working for us means you’ll be able to flex your development muscles, and you’ll have a real impact on a real product that exists in the real-world, used by thousands of people every day. It’s an exciting possibility.

We are not another boring SaaS company. We create, manufacture and deploy real hardware on a global scale, with back and front end code managing it all. You’ll have a chance to get your hands onto hardware, software, development and deployment. If you’re driven, curious, and a hacker at heart, this position is for you. 

We will provide you with all the training and tools you need, an annual travel budget, and a dynamic, fair and respectful work environment. 

Reciprocatively, we are seeking to work with someone that is honest, skilled, self-motivated, and reliable.
