We understand that everyone's unique – and that diversity of thought, experience and background is what makes a good team, great. By bringing people with different points of view together, we can represent everyone and truly reflect the communities we serve. This way, there's scope for you to make a huge difference – on us as a company, and on our clients and business partners around the world.

Job responsibilities:

• Use domain modeling techniques to allow us to build best in class business products.

• Ensure our systems are reliable and easy to operate.
• Keep us up to date by continuously updating our technologies and patterns.
• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contributes learnings and reusable patterns to improve broader team effectiveness.
• Applies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation.

Required qualifications, capabilities and skills:

• Formal training or certification on problem-solving concepts and proficient applied experience
• A desire to teach others and share knowledge. We aren’t looking for hero developers, more for team players.
• Adjusts quickly to changing priorities and conditions. Copes effectively with complexity and change. Learns and unlearns technologies and patterns quickly. Comfortable in uncharted waters.
• Can see the long term. Won’t sacrifice the future for the present. Chooses technologies and approaches based on the end goals.
• High standards. Expects personal performance and team performance to be nothing short of the best.
• Does not cut corners ethically. Earns and maintains trust.

• Hands-on experience using enterprise-authorized AI-assisted software development tools within the work environment (e.g., for coding, test creation, troubleshooting, or documentation) with demonstrated ability to critically evaluate, validate, and refine AI-generated outputs for correctness, performance, and security.
• Understanding of responsible AI use in engineering workflows, including data sensitivity considerations, secure handling of inputs/outputs, and adherence to resiliency and security expectations; ability to guide peers on safe and effective usage within team practices.

Technologies:

• We primarily use Jvm based languages (Java/Kotlin) but we also have parts of the platform that use other languages as needed.

• We are entirely cloud native and want to build a truly multi-cloud solution.
• We look at each problem independently and pick the right technology to solve it.
• We aren’t afraid to try new things but we always remember that we are looking to build something to last, and we focus on solving real world problems for real life customers.
