Senior Full Stack Software Engineer

is the world's largest and most trusted online escrow service. Buyers and sellers rely on us to hold their funds while multi-million-dollar deals are completed. Domain names, vehicles,, even entire businesses... you name it, we help people buy and sell it.

Now we're looking for a Senior Full Stack Software Engineer to join us in Sydney.

If you join a mega-cap technology company as the 10,000th hire you will struggle to figure out the impact you're making. If you join a startup, you might get to work on the latest fad, but you'll likely have few mentors to learn from, and your time will be spent working on toy problems that never change the world. Freelancer Group (that is part of), isn't like that - we're a just-right-sized business. We're small enough you'll get to really know the people you work with, but big enough you don't have to worry that the next order of whiteboard markers will empty the company bank account.

Working for us isn't your typical cog-in-the-machine type of job. We work on dynamic and interesting real world problems every day: this isn't a boring career in corporate, every step bound by rules and heavy process. Here you'll get to work on a highly diverse, global set of internet-scale challenges making a meaningful difference. Plus you get to rapidly build your own skills: the nature of the work requires cross-functional knowledge.

Working with us you'll not only build (and test, and deploy) features that scale, but you'll have a direct impact on tens of millions of users worldwide. You'll architect web applications, write optimised SQL for massive data sets, structure extensible data and application logic, and design high-quality APIs. And you'll do all that using a mix of open-source tools and best-in-class commercial software.

Our tech stack includes Python-based Flask (and some Golang) microservices, front-end code, and traditional SQL RDBMS systems. Everything runs in Amazon Web Services. You can choose your own OS for your company laptop - most of our devs use Ubuntu Linux, but it's all good

In order to succeed in this role you will have:

• The ability to write code in a few web development languages, such as Python, Golang, PHP, or Ruby
• Experience with relational databases and SQL, preferably MySQL
• A background or interest in web engineering at scale
• The ability to work in an agile team environment, continuously shipping to customers
• Linux experience
• Experience building SaaS products
• Cloud computing experience, preferably AWS
• Strong written and verbal communication skills
• A strong sense of ownership and the ability to self-manage work
• Strong troubleshooting skills and creative problem-solving ability
• Experience with designing and implementing complex software systems
• Experience with mentoring/training junior engineers

To thrive you'll also bring:

• Experience with SOA, microservice and containerised architectures
• Familiarity with development of public-facing APIs
• Experience with a current-day Javascript framework, such as Angular, React, or Vue
• Experience with TypeScript
• A strong understanding of computer networking concepts and practices
• A sound understanding of OWASP and modern web security practices
• A passion for open-source tooling and libraries

We'd consider it a bonus if you also brought:

• Strong academic achievements
• MS or PhD degrees
• A Github/Gitlab page with contributions to open source software
• Experience leading an engineering team

What we offer in return:

• A meritocratic culture with the ability to take ownership and fast track your career growth. We promote from within
• Weekly Town Halls with the all-important CEO Q&A session (you really can ask him anything, and people do)
• Catered Friday lunches - We finish each week with a catered lunch. Every week comes from a different local restaurant.
• Fully stocked kitchens - yes, we do have beer taps (and the bar has a killer view)
• Hack-a-thons - Each quarter, teams compete company-wide hacking out solutions to their own selection of customer problems and win prizes. The 2-day event is filled with games, events, shows, food and more.
• Fun events. Once, we built a soccer stadium in the office with two tonnes of turf...
• Our office at Grosvenor Place - Home of Freelancer (and Escrow) HQ, this iconic building has harbour views and offers weekly (complimentary) classes/activities/events

But wait, there's more:

• Working with Freelancer Group, our parent company, you get to change lives every day - everything we do as part of our jobs contributes to improving the lives of our users on a global scale
• Plenty of opportunities for growth - you get to work with different tech stacks, on different problems all the time. You won't get bored, and you will get plenty of chances to learn how things work
