Senior Java Engineer – We have been exclusively engaged by a leading B2B SaaS technology business to find a Senior Java Engineer with a “product engineering” mindset to join its growing team. Operating at the intersection of insurance and technology, the company is transforming its platforms into fully SaaS-based solutions, scaling internationally and shaping the future of Insurtech products.

Backed by the stability of a global parent organisation but operating with the freedom of a scale-up, the company offers the best of both worlds: long-term security and the agility to innovate.

The Role

The Senior Java Engineer will play a central role in designing, building, and scaling products that deliver tangible business value. Working closely with Product and the business, you will be leading technical initiatives, and mentoring colleagues, while also helping to shape the organisation’s engineering culture.

This is an opportunity for an engineer who sees software development as a means to solve meaningful problems, not just to write code. The role requires someone who enjoys solving complex challenges, influencing architectural decisions and building scalable, resilient systems.

Key Responsibilities

• Designing and developing production-ready features and services in Java (Spring Boot) and cloud-native environments.
• Contributing to system design and architecture, ensuring simple and pragmatic solutions to complex problems.
• Working collaboratively with Product Managers and teammates to balance the delivery of new features with long-term technical improvements.
• Owning code from idea through deployment and operation, including AWS design, security, and observability.
• Mentoring colleagues, conducting code reviews, and supporting a culture of learning and improvement.

Candidate Profile

• Significant experience in modern Java development (Spring Boot, Kotlin, or similar).
• Strong track record in designing and evolving scalable, Cloud-based systems.
• Practical experience with iterative development, automated testing, and CI/CD.
• A pragmatic and collaborative approach, with the ability to balance short-term needs and long-term goals.
• Excellent communication skills, with a passion for teamwork, knowledge sharing, and continuous learning.
