• Implement idempotent transaction logic, robust error handling, and reconciliation mechanisms critical

• to financial operations.

• Develop secure RESTful and SOAP APIs with multi-layer authentication, authorization, and audit trail

• capabilities.

• Optimize database queries, stored procedures, and schema designs for high-throughput financial

• transaction processing.

Engineering Quality & Standards

• Write clean, well-documented, testable code that meets enterprise security and compliance standards.

• Conduct and participate in thorough code reviews to detect logic errors, edge cases, and security issues and vulnerabilities before deployment.

• Ensure all delivered systems undergo rigorous testing (unit, integration, UAT) with documented test evidence.

• Maintain detailed technical documentation including design specs, data flow diagrams, and deployment guides.

Collaboration & Delivery

• Work closely with business analysts, operations teams, and compliance to translate requirements into

• precise technical solutions.

• Manage software project delivery within agreed timelines, proactively flagging risks.

• Support production incidents with urgency, perform root cause analysis, and implement lasting fixes.

• Continuously evaluate existing systems for performance gaps and drive optimization initiatives. 

Experience & Qualifications:

Education

• Bachelor’s degree in computer science, Software Engineering, Electrical/Electronic Engineering, or

• a closely related field.

• A master’s degree or relevant professional certification is an advantage.

Experience

• Minimum of 5 years of hands-on software development experience, with at least 3 years in a bank, fintech, or payment processing environment.

• Demonstrable experience building and deploying payment or funds transfer systems (NIP, RTGS, SWIFT, card processing, or similar).

• Proven track record of delivering financial software independently, with strong ownership from design through production.

• Experience working with regulatory systems (e.g., CBN reporting, AML, FIRS) is a significant advantage.

           

Technical Skills & Competencies

• C# / .NET (ASP.NET Core, .NET Framework) — primary development language; must be highly

• proficient.

• SQL Server — advanced T-SQL, stored procedures, indexing strategies, and schema design for

• financial data.

• HTML5, CSS3, JavaScript / TypeScript — front-end development for internal and customer-facing

• web applications.

• RESTful API design and implementation, including versioning, security, and documentation

• (Swagger/OpenAPI).

• Git-based version control, CI/CD pipelines, and structured release management.

General Competencies:

  

Strongly Advantageous

• ISO 20022 (pacs.008/002/028), NIBSS NIP/PAPSS, React/Angular/Blazor, NoSQL (MongoDB, Redis), messaging (RabbitMQ, Azure Service Bus), reporting (Power BI/SSRS), and cloud (Docker, Kubernetes, Azure/AWS).

Key Competencies

• Detail-oriented; strong analytical and problem-solving skills; self-driven with end-to-end ownership; clear communicator; proactive risk awareness; continuous learner.

Mobile (Advantageous)

• Cross-platform apps (.NET MAUI, Xamarin, Flutter, React Native), mobile UX, secure storage, APIs, push notifications, biometrics, and app store deployment.
