About the Role
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 including sports competitions, federations, brands, and broadcasters. Our team operates on an “internal open source” model, valuing 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 suits someone who balances high-level system design with a pragmatic, product-first mindset. You will not only execute projects but also 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, suggesting technical and feature trade-offs to ensure solutions fit the brief and deliver on time without compromising quality.
- Engineering Excellence: Develop robust, low-latency solutions using AWS services.
- Collective Contribution: Participate in our “open source” internal culture by contributing to a shared ecosystem of services and tools, prioritizing the best collective outcome over component ownership, with an emphasis on scalability.
- Event Support: Provide go-live support for solutions focused on specific sporting events with fixed deadlines.
- Conscious AI: Leverage AI tools to accelerate development and enhance system logic while maintaining human oversight and accountability.
- Lean XP Practices: Work within an XP-influenced environment, utilizing Test-Driven Development (TDD) and continuous delivery to maintain speed and quality in high-stakes environments.

Requirements

Experience
Several years of relevant experience, ready to take on a Mid-level role. Applications from recent bootcamp graduates (e.g., Makers Academy, Le Wagon) are welcome.

Technical Skills
- Strong proficiency in Python is essential.
- Comfortable learning and moving between new languages as services evolve.
- Experienced user of agentic coding workflows, actively leveraging AI-assisted development tools such as Claude Skills, Model Context Protocol (MCP), and autonomous agents.
- Experience building and scaling event-driven architectures using AWS Serverless technologies (Lambda, EventBridge, DynamoDB).

About You
- Sports literate: You follow sports and understand the context of the data and markets we build for.

Nice to Haves
- Hands-on experience with Java.
- Knowledge of the sports business.
- Hands-on experience with Infrastructure as Code tools such as Terraform.
- Proficiency with SQL and NoSQL data modeling for high-volume, low-latency environments.
