Software Engineer (Java)

DESCRIPTION Would you like to leave your mark in the booming cloud-native & fin-tech industry? Would you like to show your ideas and bring them to life?    Ohpen is seeking a .NET Developer who goes beyond writing code and takes ownership of system architecture, technical direction, and long-term design decisions.  This role is ideal for someone who enjoys shaping complex systems and working closely with product and business stakeholders to build scalable, maintainable solutions.  BRIEFING As a .NET engineer, you will play a key role in defining technical specifications, setting engineering standards, and delivering robust, testable, and well-documented solutions.    You will be expected to contribute your expertise, challenge assumptions while continuing to deepen your own technical and domain knowledge. ABOUT YOU * 3+ years of professional experience with .NET / C# in production environments * Understanding of software architecture principles (e.g., SOLID, DDD, Clean Architecture, microservices vs. monoliths) * Hands-on experience with:  * ASP.NET / ASP.NET Core * RESTful/SOAPAPIs and integration patterns * Integration with 3rd party system * SQL and/or NoSQL databases * Even driven architecture * Strong communication skills and the ability to explain complex technical concepts to both technical and non-technical audiences WHY US? We’re building a real-time, cloud-native core banking platform for two major markets. No legacy systems. Just real customers, real code, and real impact. You’ll work in small, strong teams of engineers who care about their craft.  You will be working on a product, which is part of a whole suite of products offered to our customers. Our team develops and maintains 15 year old product built on .Net, PostgresSQL, Docker and deployed on AWS cloud.

DESCRIPTION Do you think like an engineer first and a “language specialist” second?    Are you the kind of person who loves to experiment, challenge tools (including AI), and find better ways to build software – even if it means learning something completely new?  If you enjoy going the extra mile, playing with ideas and turning them into robust solutions, we’d love to talk to you. BRIEFING You’ll join our Mid‑office team, where complex mortgage and credit decisions are turned into services and APIs that drive real‑world outcomes for our customers.  Your role would be to understand how the pieces fit together: how services interact, how data flows through our platform, and how design choices affect reliability and customer experience.  You’ll be designing and improving components in a cloud native core banking environment and help us keep systems understandable and maintainable over time.  AI will be one of your tools: you’ll use it to explore options, generate code snippets or tests, and speed up routine work, but you’ll always stay in the driver’s seat, by deciding when AI’s suggestions need to be challenged or refined.  This role is for someone who enjoys analyzing problems, forming a clear vision of the solution, and then using both their own skills and AI‑powered tools to bring that vision to life. You’ll collaborate closely with other engineers and product colleagues, discuss trade‑offs, and help us move from “incremental evolution” to genuine “revolution” in how we design and operate our Mid‑office services. ABOUT YOU * You understand code and system architecture beyond syntax: you can reason about how components are structured, how they communicate, and how changesimpactthewhole system. * You are open‑minded and curious, and youdon’thesitate to learn something new when it helps you build a better solution. * You are comfortable using AI as a collaborative tool – crafting precise prompts, explaining clearly what you need, and evaluating AI‑generated output against your own standards. * You enjoy discussing ideas, challenging assumptions (including those made by AI) ! If this role resonates with you, and you enjoy trying new things, you’re welcome (but not required) to send us a short video where you show or tell whatever best captures how you think about code, systems and using AI as your teammate.
