About Us

Weavr is the easiest way for businesses to embed relevant financial services into software at the point of need. Weavr recently secured its Electronic Money Institution (EMI) licence to support European customers and continues to invest in premium localised payments capabilities to better serve existing and future B2B SaaS partners.

Founded by serial entrepreneurs who are leaders in payments and fintech, we're a team of can‑do builders at the frontier of the embedded‑finance industry. Our team is characterised by smart, kind, and high‑performing experts who value respect, openness, and trust. Weavr is small enough for every individual to make an impact, yet operates at the level of a more mature organisation.

Engineering at Weavr

We are looking for a Senior Java Developer to join our software development team to help us develop further our embedded banking and payments platform.

As a Senior Java Developer you will help deliver innovative technologies that make integrating banking and payments services as simple, flexible and accessible as any other API.

As a team, we aim to be agile and deliver solutions for our customers in a fast and efficient manner. Our platform is already being used by customers, and as part of our development team you will work on the many enhancements we have planned. With your expertise and experience in engineering solutions for complex problems, you will help shape the future platform and continuously raise the bar for embedded banking and payments.

We're pragmatic engineers who value shipping over perfection. We encourage experimentation, learn from failures, and run regular hackathons. Engineers have autonomy to make technical decisions whilst we maintain quality through collaboration and automation.

About You

The section below describes our "ideal candidate." However, our hiring process places a strong emphasis on aptitude and passion. If you haven't used every specific tool or haven't met all the skill and experience criteria listed, please don't let that discourage you from applying.

However, it's important to note that you bring extensive java engineering experience working with design patterns and frameworks such as Spring/Micronaut.

• 5+ years of experience in a similar role.
• Strong communication skills including technical documentation, code reviews, and cross‑functional collaboration.
• Great at communicating ideas and working in a team.
• A Java guru, with extensive knowledge and experience of associated technologies such as the Spring framework.
• Advanced knowledge of software design patterns.
• Experience with microservice based architectures, and related tools and technologies such as Micronaut (or Spring Boot), REST (both implementing and consuming), and Kafka (or similar message broker technologies such as RabbitMQ).
• Keen on best engineering practices.
• Experience with TDD, CI/CD pipelines, and modern engineering practices.
• Proven ability to design scalable, maintainable solutions following SOLID principles.

Desirable:

• Experience with AI‑assisted development tools (GitHub Copilot, ChatGPT, or similar) for code generation, debugging, and refactoring.
• Experience in payments, fintech, or regulated industries.
• Knowledge of Micronaut framework.
• Experience with reactive programming (Project Reactor, RxJava).
• Familiarity with MongoDB, Redis, jOOQ, Flyway.
• Experience with Docker and Kubernetes or container orchestration.
• Understanding of security best practices in financial services.
