Product Software Engineer
We are looking for a Product Software Engineer to join our Technology Solutions division.
The Technology Solutions squad builds solutions that unlock value for clients across the sports industry. We work mainly on a project basis, delivering custom-built applications, APIs, and AI tools for clients across sports competitions, federations, brands, and broadcasters.
Our team operates on an "internal open source" model; we value collective stewardship of our codebase rather than individual silos. You will be a key driver in understanding the "why" behind our systems and the customers they serve.
This role is for someone who balances high-level system design with a pragmatic, product-first mindset. You will not just execute on projects; you will help shape them while coaching and mentoring those around you.
What You'll Do
- Solution Stewardship: Partner with PMs and stakeholders to build custom solutions. You are expected to suggest technical and feature trade-offs to ensure our solutions fit the brief and deliver in the time available without compromising quality.
- Engineering Excellence: Develop robust, low-latency solutions using AWS services.
- Collective Contribution: Participate in our "open source" internal culture. You will contribute to a shared ecosystem of services and tools, prioritizing the best collective outcome over component "ownership", and emphasizing scalability.
- Event Support: Our solutions are often focused on specific sporting events, meaning fixed deadlines and go-live support requirements that you will help to provide.
- Conscious AI: Leverage AI tools to accelerate development and enhance system logic, whilst maintaining human oversight and accountability.
- Lean XP Practices: Work within an XP-influenced environment, utilizing TDD and continuous delivery to maintain speed and quality in a high-stakes environment.
