Job description

Senior Software Engineer - Backend & Infrastructure

Moon Intelligence | Hybrid/Remote | Full-time

About Us

Moon Intelligence is a technology company specialising in software and quantitative models for the sports betting and prediction markets industry.

We develop proprietary pricing models, market access infrastructure and trading technology that enables our clients to operate across a wide range of sports and exchanges.

Our team combines expertise in quantitative modelling, software engineering and sports markets to build reliable, high-performance systems.

The role

We're looking for a Senior Backend & Platform Engineer to take ownership of our AWS infrastructure while contributing directly to the development of our software platforms.

This is a hands-on engineering role combining cloud infrastructure and application development. You'll be responsible for ensuring our production environment is reliable, secure and scalable, while spending a significant proportion of your time writing production software.

Depending on your background, your development work will focus on either our core Java platform or our Python-based market access and trading technology.

You'll be part of a small engineering team with considerable autonomy and the opportunity to make a meaningful impact across our systems.

What you'll be working on

• Taking ownership of our AWS infrastructure, including reliability, security, performance and ongoing improvements.
• Developing and maintaining production software in Java/Spring Boot or Python.
• Managing containerised services, deployment pipelines and infrastructure as code.
• Improving monitoring, observability and incident response.
• Identifying and resolving infrastructure and application issues in production.
• Working closely with other engineers to improve the architecture, reliability and maintainability of our systems.

What we're looking for

• Strong commercial software engineering experience in either Java/Spring Boot or Python.
• Substantial hands-on AWS experience, including responsibility for production infrastructure.
• Experience working with containers and infrastructure as code.
• Good understanding of CI/CD, monitoring and observability.
• Solid knowledge of cloud networking, IAM and security.
• Strong debugging and problem-solving skills across infrastructure and application code.
• Ability to work autonomously, take ownership and collaborate effectively within a small engineering team.
• We don't expect candidates to be proficient in both Java and Python. Strong experience in either language, combined with solid infrastructure expertise, is what matters.

How we work

We're a small, technically focused team where engineers have meaningful ownership of the systems they build.

We make extensive use of modern AI-assisted development tools and value engineers who can use them effectively while maintaining high standards of engineering judgement, testing and code quality.

We operate a hybrid working model, with opportunities to collaborate in person at our London office, but we're also open to fully remote candidates with the right experience and approach.
