The Role

Rokt’s engineering teams are expanding rapidly. Currently approximately 120 engineers in our Sydney office, and a small team in New York, and we have ambitious plans to grow the team in both regions this year.

Our Sydney team is looking for talented Senior Software Engineers, with a proven track record in developing world class cloud based systems. There are multiple opportunities in Backend, Frontend and Fullstack roles, to join any one of our 17 scrum teams and make an immediate impact. We encourage engineers to move between teams, and even between regions, to facilitate their personal development goals and energise their career.

The Tech

Rokt is building a globally distributed microservices based platform, hosted on AWS. Our tech stack comprises a multitude of different technologies, chosen by each team to solve their specific problem.

We have invested heavily in an event based architecture, utilising message queuing technologies, pub/sub models, and event streaming to construct a highly available, high volume, distributed system. We have services in 5 AWS regions, with the core systems residing in Oregon USA.

On the backend we employ Python, C#, Golang, Java and NodeJS, to name a few. The frontend is crafted with React and Angular frameworks, using Typescript and raw JavaScript. A variety of relational and nosql databases such as Postgresql, DynamoDB and Redshift facilitate our persistence layer and data warehousing needs.

All teams craft their infrastructure as code using CloudFormation, and run their services on Kubernetes. Each team owns their build/test/deploy pipelines and system monitoring & alerting. Our philosophy is you build it, you own it.

About You

You are a self-starter with a genuine passion for software engineering. You strive for quality in everything you do, whilst remaining pragmatic and value driven.

You have a track record of overcoming challenges through innovative yet practical ideas and regularly discover, learn and experiment with new technologies. You demonstrate ownership and consistently drive to tangible outcomes.

You leave your ego at the door, and constantly seek opportunities to learn from or mentor your colleagues. You take ownership of your failures and recognise the growth opportunities they present.

You are a respected individual who works well with your team and management alike.
