If you're passionate about cutting-edge technology and want to make a significant impact in the sports betting industry, we want to hear from you!"
When it comes to being successful at Sportserve, there's more to it than just being really good at the technical stuff.
It's also your ability to be an awesome problem solver.
And here's the thing, we totally get that we can't all be experts in everything, right?
So, it's all about having that thirst for knowledge and being passionate about learning.
You'll also need amazing attention to detail, so if something seems off, you won't rest until you've figured out what's going on.
We see ourselves as a cool group of people who love coming up with new ideas and making things happen.
As long as you have a true passion for creating awesome stuff, you'll fit right in.
What you'll be getting up to:  We are looking for someone to work closely with our product owners to help shape and build the future of our tools and products.
You'd spend your time developing and improving existing projects, for example:    - Building new websites and pages based on provided technical and functional specifications.
- Implementing different strategies for existing products and tools based on requirements.
We'd also do a ton of work together like:      - Architecting and developing new features.
- Prototyping and evaluating potential implementations.
You would spend a lot of time programming, brainstorming on hard problems, and prototyping different ideas.
You wouldn't be just churning through tickets in the backlog — you'd be helping to design entirely new products, figuring out what exactly we're even building and why.
While being a somewhat big company, we're split into small teams which means that even though we each have our areas of expertise, we all wear many hats.
We're looking for a programmer, but you'd also help out with things like:     - Managing Git VCS issues and fixing bugs.
- Writing and improving the documentation for the products and tools we make.
- Helping customer support answer customer questions.
- Troubleshooting problems during live communication with other teams If you've ever maintained a large project, working with us carries a lot of the same responsibilities.
Here are a few recent projects you might have worked on if you were already part of the team:    - Building next version of our products from scratch with latest technologies.
- Building a performance testing architecture and laying the groundwork that will be used company-wide.
- Refactoring the actual production application to simplify and speed up performance without any down-time.
Key Responsibilities: Develop websites based on technical and functional specifications provided by the client;  Continued maintenance, development, and bug fixes for the existing web sites;  Utilise source control tools such as Gitlab for maintaining code versioning and releases;  Test the website on different browsers and identify any technical problems;  Work with the team to manage, optimise and customise multiple web applications;  Attend daily meetings to report on assigned tasks' progress and attend fortnightly meetings for project planning and other meetings from time to time;  Complete tasks & deliver projects on-time and to the highest standards;  Contribute ideas for making the application better and easier to use.
Comfortable working on-call.
