We’re looking for a Senior Software Engineer to join our London-based engineering team. This is a strategic, hands-on role where you’ll combine technical expertise with operational thinking to help shape the future of our platform. You’ll lead the charge in simplifying our tech stack, championing industry-standard tools, and guiding the transition toward AI-assisted development.

In this role, you’ll take ownership of key responsibilities that help drive team and business success. Your day-to-day will include:

• Leading the design and delivery of robust, scalable solutions using industry-standard technologies.
• Driving the shift away from custom, hand-rolled systems toward proven tools like Kafka.
• Maintaining and improving existing Scala-based code while advocating for simplicity and efficiency.
• Collaborating with cross-functional teams to ensure solutions align with business goals.
• Mentoring and supporting junior engineers, shielding them from unnecessary complexity.
• Participating in architectural decisions and requirements engineering.
• Embracing AI-assisted development to accelerate delivery and improve productivity.
• Ensuring systems are performant, reliable, and easy to maintain.

We’re looking for someone with the skills, experience, and mindset to thrive in this role. Ideally, you’ll have:

• Strong experience in software engineering with Scala (essential for current stack).
• Familiarity with messaging systems like Kafka and a preference for industry-standard tools.
• Solid understanding of SQL databases and Linux for debugging and operations.
• Experience with software architecture, UML, and requirements engineering.
• Ability to navigate complex organisational dynamics and advocate for simple, robust solutions.
• Confidence to challenge over-engineering and stand firm on best practices.
• A forward-thinking approach to AI-assisted development and emerging technologies.

• Exposure to sports data or betting systems.
• Experience mentoring or leading small teams.

At TxODDS, you’ll be part of a well-established, technology-first company with ambitious growth plans and a global footprint. You’ll work alongside brilliant minds in a culture that’s fun, relaxed, and hardworking – where innovation and collaboration are at the heart of everything we do.
