Senior Software Engineer in Leeds

The Sports Super Tribe is comprised of 5 self-sufficient tribes, encompassing over 60 squads of Engineers, QA, and associated roles across Porto, Dublin and Leeds. Together, we are dedicated to delivering fast, distinctive, dynamic, and trusted sports betting experiences, each tribe driven by a clear vision to develop best-in-class customer experiences.

As part of this role, you’ll be working with the Reward and Free to Play tribe with the goal to deliver fast, innovative and trusted experiences that enhance player enjoyment, provide valuable rewards and engage our customers by elevating sports betting.

You’ll be working in a team that understands the play and reward technology and knows how to deliver great products that drive the most engaging customer experiences. Providing operational support for the SBG Free to Play apps (web, mobile, and native) and the Sports Generosity systems for all UKI region brands: Sky Betting and Gaming, Paddy Power, Betfair, and Betfair International / Brazil.

As a Senior Software Engineer for front-end, you will work in empowered, multidisciplinary teams, autonomously tackling complex challenges that provide the very best experiences and products for a growing community of millions of players. You will own and become subject matter experts in areas of product and technology stack and will be the go-to person for those areas. You’ll have an active involvement in technical decision-making forums and architecture reviews. You work efficiently and routinely deliver the right things with limited guidance. Your work focuses on complex, ambiguous problem areas in existing or new software initiatives. You take the long-term view. You consider where each system is at in its life cycle and where appropriate, proactively fix architecture deficiencies and make existing systems simpler. You’re passionate about code quality, security, and scalability to ensure our systems meet end-user needs and business objectives, balancing technical ideals with commercial realities. You’ll champion non-functional requirements (monitoring, alerting, logging) for optimal system performance and user experience and drive continuous integration and delivery. You can take the lead on large projects that require the work of your team. You know how to divide a software project into parallel work that can be performed by you and other software engineers and then reassembled successfully into a cohesive launch. You enjoy coaching and developing other Software Engineers' technical skills.

How you’ll do it:

• Solid experience building and designing highly scalable, fault-tolerant and always-available systems.
• Solid understanding of design patterns and architectural principles.
• Building Web apps using React (JavaScript/ReactJS/Typescript).
• Building mobile apps using Swift, Kotlin, and React Native.
• Good grasp on relational, and non-relational databases, messaging queues and concurrency.
• Architectural & Engineering Leadership: Owning system architecture, providing design guidance, and driving best practices across security, quality, and operational excellence.
• Exemplary Code & Quality: Delivering simple, high-quality code that sets standards and motivates the team.
• Complex Problem Resolution: Resolving root causes of endemic problems, removing bottlenecks, and building consensus across discordant views.
• Team Empowerment & Mentorship: Developing colleagues, improving technical skills, and ensuring team strength that is self-sustaining.
• Customer-Centric Operations: Providing excellent customer support and ensuring system performance meets user needs.

Tech Stack:

Our product’s frontend is developed using React, PHP, Node.js, and JavaScript. Strong experience with these technologies is preferred. As a senior engineer, you’ll be expected to contribute to architectural decisions, mentor others, and lead by example — while also working with Java in parts of the stack where integration is required. You’ll collaborate with cross-functional teams and engage with a broader technology ecosystem that includes Java, TypeScript, AWS, Kafka, Spring, MySQL, and Kubernetes, so familiarity with backend and infrastructure concepts is a plus. We also develop and maintain mobile applications (iOS and Android) using technologies like Swift, Kotlin, and React Native. Any experience or interest in mobile development would be highly valuable, as it helps us collaborate more effectively across teams and deliver a consistent product experience.

What’s on offer:

• £/€1,000 learning fund.
• Twice-yearly bonus (with part of it guaranteed!).
• Unlimited Holiday.
• Pension contribution scheme.
• Private healthcare.
• Hybrid Working - Access to thousands of Udemy courses.
• Invest via the Company Sharesave Scheme.
