We need passionate, determined, courageous, and principled software engineers like you to help us achieve this mission. If what you need next in your career is an opportunity to be empowered to make your own decisions, learn from your mistakes and execute what works, Apex FinTech Solutions, a PEAK6 Group company, is likely the place for you.

    This is a role for someone who flourishes in a fast-paced and collaborative environment Though our current project is written in Java and deployed to EKS, we routinely encounter and work in different languages, frameworks, and systems. We value engineers who are proficient in multiple languages because we know they can quickly learn the next one that comes up. We’ve recently written software in Java, Python and Go. 

    What you will do all day:

    • Think through hard problems and solve them at all layers of the enterprise 
    • Develop and maintain clean and consistent APIs for applications that are used internally and externally 
    • Write self-documenting and well-tested code with an emphasis on sustainable development practices. Work as a part of small, productive development team that puts an emphasis on code quality, peer reviews and strong engineering practices 
    • Help grow the team. As one of the first PEAK6 team members in Belfast, you will help recruit the right talent and establish a culture that developers love to work in. Your coaching and mentoring will prove important in growing the Belfast Office. 

    What you need to succeed: 

    • The permanent right to live and work in the U.K.

    • Four more years of professional experience working as a part of a multi-person development team, doing code reviews, testing, CI, trunk-based development, and/or other modern software practices. 
    • Demonstrated skills in software design. 
    • The ability to learn new and unfamiliar technologies quickly, as required. 
    • Adaptability: while you enjoy establishing process and standards, you understand the need to be flexible and enjoy trying new things. 
    • An intuitive understanding of distributed architectures – experience with reactive architectures is a big plus. 
    • A DevSecOps mindset and a driving desire to deliver value through software. 

    As part of our interview process, you will meet with members of both our Belfast and US offices. Everyone you meet, shares the same values: Open and Honest Communication, Teamwork and Collaboration, Involving Everyone, Leaders Who Serve and Personal Accountability.
