Full job description

About the role: You'll be working on the backend of systems that move money; payment processing engines, merchant integration services, and the microservices that orchestrate transactions across multiple payment rails. This means designing APIs that handle edge cases gracefully, building services that fail safely when things go wrong, and ensuring our platform can scale as transaction volumes grow.
We're looking for someone who is comfortable in the full lifecycle; from whiteboarding a technical approach with stakeholders, to writing clean Java code that other developers will maintain, to debugging production issues when required. The ideal candidate is someone who has built distributed systems before and understands the trade-offs between consistency and availability. We're looking for someone who spots problems in the design phase, and who cares about getting it right.

About the Company: MiFinity is a dynamic, licensed, and regulated fintech leader offering cost-effective, end-to-end payment solutions for businesses, merchants, and consumers. With over 20 years of experience in online payments, we have built a highly secure technology platform and a growing global network of financial and banking partners. Our core service, the MiFinity eWallet, enables seamless money transfers worldwide through our extensive bank network and local payment options. As we continue to expand across multiple global verticals, we foster a collaborative, inclusive work environment while maintaining a start-up culture that values flexibility, autonomy, and innovation across all of our offices in Dublin, Malta, and Belfast.

Benefits:

Private Healthcare and Dental care post probation
Continuous Development Program sponsoring further education through courses and workshops.
Free parking (first come first serve basis)
Remote work allowance post probation beginning at 3 weeks in year 1 and increasing with tenure
Additional special leave days such as extra day for birthday/moving home, extra days for marriage, graduation, citizenship ceremony
Study and Exam Leave to further support career and educational growth.
Generous company pension scheme with employer matching

Responsibilities:

Develop new in-house products
Translate application storyboards and use cases into feasible functional applications
Design, build, and maintain efficient, reusable, and reliable Java code
Write clean code supported with unit testing modules
Ensure the best possible performance, quality, scalability and responsiveness of the applications
Document features and share knowledge within the team
Collaborate with other team members and stakeholders
Help maintain code quality, organization, and automatization including undertaking peer code reviews
Perform integrations with 3rd party applications

Qualifications:

Minimum 3+ years of JAVA enterprise software experience
Bachelor’s or Master’s degree in Computer Science or related field
Self-Motivated Individual with excellent interpersonal and communication skills having the ability to work in a team and on own initiative
Experience with JAVA Spring Boot, Caching methodologies and Database Design would be considered as a great plus
Experience in working within a microservice architectural approach
Ability to write clean code with an eye for performance and scalability
Strong analytical and problem solving skills
Familiar with various software design principles and architectural patterns behind a scalable application
Creating database schemas that represent and support business processes
Desirable to have experience with RabbitMQ & Docker
Focused on driving standards in AI assisted development
Experience in financial software development will be considered an asset.
