Job description

We are looking for a Backend Engineer to build and maintain the services and APIs that power our sports intelligence products for internal teams and external clients. You will work across backend services, data platforms, model-serving layers, and high-traffic systems, with a strong focus on reliability, scalability, and clean API design. This role is suited to an engineer who enjoys owning services in production, thinking about system behaviour at scale, and contributing to architecture and technical decisions.

Key Requirement:

• Build and maintain scalable backend services and APIs supporting sports intelligence products.
• Design and own service and API contracts consumed by internal engineering teams, external clients, and partners.
• Manage API versioning, backward compatibility, documentation, and breaking changes.
• Build services that reliably serve data products and model outputs across real-time and high-traffic use cases.
• Integrate backend services with data platforms, warehouses, and model-serving layers.
• Write clean, maintainable, well-tested code aligned with engineering best practices.

Scalability & Production Readiness :

• Design backend systems with performance, scalability, and reliability in mind, particularly for read-heavy workloads.
• Implement appropriate caching strategies to improve system performance.
• Ensure services are production-ready with appropriate monitoring, logging, alerting, and operational documentation.
• Support troubleshooting and resolution of production issues.
• Ensure smooth operational handover to teams responsible for running the services.

Engineering Collaboration :

• Contribute to architecture discussions and technical decisions across the team.
• Participate actively in code reviews and maintain high standards for code quality.
• Work from product and technical specifications while identifying gaps and asking the right questions when requirements are incomplete.
• Collaborate with data, ML, product, and other engineering teams to deliver reliable end-to-end solutions.

Development Practices :

• Follow established CI/CD and testing practices to ensure safe and reliable releases.
• Contribute to improving engineering workflows, development standards, and operational practices.
• Stay updated with relevant backend, cloud, and infrastructure technologies.

Background and Experience:

Required

• 5+ years of experience building and shipping backend services in production.
• Strong proficiency in Python.
• Strong SQL skills and working knowledge of relational databases.
• Experience designing and developing REST APIs, including API versioning and backward compatibility.
• Good understanding of caching, performance optimisation, and scalability in read-heavy systems.
• Experience with cloud infrastructure and containerised application deployment.
• Familiarity with CI/CD practices, automated testing, and observability tools.
• Strong understanding of production software engineering practices.
• Ability to work independently from technical specifications and proactively clarify ambiguous requirements.
• Bachelor's degree in Computer Science, Engineering, Information Technology, or a related field.

Good to Have

• Experience working with real-time or event-driven systems.
• Exposure to streaming technologies.
• Experience building APIs consumed by external clients or partners.
• Experience with data-intensive applications, analytics platforms, or data products.
• Exposure to model-serving or ML-powered applications.
• Interest in sports and familiarity with sports data.

The Edge:

You build backend systems that don't just work; they stay reliable when the game is on and millions of fans are watching.

What We Offer:

• Global Exposure: Work with marquee sports properties across 40+ sports worldwide.
• Innovative Culture: A "fan-first" environment that values curiosity, quality, and fun.
• Flexibility: Monday to Friday schedule with flexible timings.
