Role Overview
We are looking for a deeply hands-on Senior Java Engineer who can provide technical leadership while continuing to design, build and ship production code.

The environment consists of distributed, cloud-native systems, with Java as the primary language and Python used across parts of the wider platform.
You will collaborate closely with Product Owners, DevOps engineers and other development teams, helping shape technical solutions across multiple services and translating product requirements into scalable backend architecture.
Key Responsibilities:

- Contribute to Python services and codebases when required
- Work across approximately three to four interconnected microservices
- Make and influence technical and architectural decisions
- Break down complex requirements and guide their technical implementation
- Review code and establish strong engineering standards
- Mentor engineers and provide technical guidance without formal line-management responsibility
- Collaborate with Product Owners to evaluate requirements, trade-offs and delivery approaches
- Build and operate cloud-native services, primarily on AWS
- Deploy and run containerised applications using Kubernetes and Docker
- Work with DevOps engineers on CI/CD, deployment, scalability and reliability
- Use data, analytics and operational insights to support technical decisions
- Contribute to testing, documentation and continuous improvement throughout the SDLC
- Support the adoption of AI-assisted engineering tools and solutions where appropriate
Requirements:
- At least 5 years of professional backend engineering experience
- Strong,
recent and hands-on commercial experience with Java

- Good knowledge of SQL and relational databases
- Practical experience with CI/CD pipelines and modern software-delivery practices
- Experience influencing architecture or leading technical decisions
- Ability to review code and mentor other engineers
- Strong understanding of testing, maintainability and production code quality
- Comfortable working across several services and technical priorities simultaneously
- Strong communication skills and the ability to work with both technical and product stakeholders
- Professional working proficiency in English (C1+)
Nice to have:
- Experience with Azure alongside AWS
- Experience building or integrating AI-enabled products
- Knowledge of analytics, data-processing or event-driven systems
- Experience working in an international, distributed engineering environment
- Previous experience supporting several engineering teams or product areas
What's on Offer:
