Full Stack Engineer

ABOUT US

Sing King is on a mission to delight millions of singers around the world through our portfolio of games and singing experiences across multiple platforms.

Our successful flagship YouTube channel welcomes over 14 million subscribers and 30 million unique viewers each month, and along with our latest Mobile Game release we are continuing to build innovative and exciting products that spread joy to singers wherever and whenever they sing.

We are a team of music lovers, game enthusiasts and entrepreneurial spirits. We are passionate about our vibrant and growing community of global singing fans. This is a unique opportunity to play a key role in the growth of an ambitious, nimble and fast-growing entertainment business. Join us!

ABOUT THE ROLE

As our full-time Full Stack Engineer, you will help transform processes and develop fast, reliable web-based tools and apps that deliver impact. This role is a great fit if you enjoy taking ownership of areas that don’t yet have clear answers, and turning problems into scalable, forward-thinking solutions. You connect points of commonality across the business and wrap them into combined or complimentary solutions.

This role sits within the Data & Tools function, responsible for building the systems that allow Sing King’s data, content, and products to operate reliably and scale intelligently.

At the heart of Sing King is our CMS. It’s responsible for orders, data validation, third-party reporting, distribution, and more. Under your guidance, you’ll evolve us from our existing combination of backend and frontend systems into a new bespoke solution incorporating an API currently being developed in Python (FastAPI with PostgreSQL) and a web-app frontend in React.js or similar.

WHAT YOU’LL DO

Lead the CMS architecture, the heart of the creation and distribution of our assets and data. In collaboration with the Senior Leadership you’ll define, scope, and plan improvements, new features, anticipating business needs before they happen.
Maintain and develop our internal REST API that centralises business logic for the CMS, tools, asset management, data validation, and publishing of Karaoke content.
Transform the CMS frontend to deliver a fast, intuitive experience, built around how people actually work.
Design and build automation workflows that remove manual toil from content production, such as thumbnail generation, media transcoding, uploading, scheduling, playlist generation, web-scraping and more.
Prototype and develop simple light web-apps and services that empower internal teams or service our fans, whether that’s Discord/Slack bots, or simple ways for the public to request songs and submit user-generated content.
Collaborate with Data experts to turn models and research into internal tools and help solve data quality challenges through fuzzy matching, LLM-assisted enrichment, or other solutions.

WHAT YOU’LL BRING

Organisation - Ability to manage multiple technical priorities with excellent time and project management.
Agile approach - Can develop scrappy Proof of Concepts to pitch new ideas and generate buy-in, as well as making swift pivots if business priorities change.
Attention to detail - Can deliver accurate results that are key to decision-making and maintaining high quality deliveries with our music industry partners.
Creativity to solving problems - Able to translate complex business requirements into novel and practical designs, that make sure every need is taken care of.
Security conscious mindset - Solid understanding of software engineering fundamentals, data privacy, and secure coding practices.

DESIRED SKILLS

Strong programming skills – Proficient in languages such as Python, Node.js, and JavaScript, with a solid understanding of core engineering principles.
Version control & deployment practices – Strong experience with Git/GitHub and CI/CD workflows, with a focus on clean, reliable releases.
Cloud & backend systems – Experience working with cloud platforms (e.g. Google Cloud Platform) and backend systems, including deploying and maintaining production-ready web applications.

BONUS POINTS

Passion for karaoke, rhythm games, or community-led mobile games
Experience with no-code, low-code platforms such as Retool.
Experience with popular web scraping methods.
Experience with PostgreSQL and BigQuery
