At Finastra, we’re a global leader in financial services software, dedicated to expanding access to financial services and shaping what’s next for the industry. Our technology powers mission‑critical solutions across Lending, Payments and Universal Banking, supporting over 7,000 customers, including 80% of the world’s top 50 banks, in more than 110 countries.
The Senior Software Engineer designs, builds, and evolves production systems across Finastra’s lending platform—a cloud-native, Azure-hosted ecosystem serving lending origination, underwriting, compliance, and servicing workflows. This is a system-ownership role: you are responsible for the quality, scalability, and operational readiness of the software you deliver, not just the code you write.
AI-assisted development is the standard way of working on this team. You will be expected to use AI tooling daily to accelerate delivery while maintaining the engineering rigor required of enterprise financial software.
Responsibilities & Deliverables
- Design and implement production-grade services and UI features across the lending platform
- Own technical decisions that balance delivery speed with long-term system health and maintainability
- Build and maintain RESTful APIs, background services, and event-driven integrations.
- Write clean, secure, and testable code; participate in code reviews enforcing SOLID principles, async/await correctness, and EF Core best practices
- Collaborate closely with product management, UX design, and quality engineering from concept through delivery
- Contribute to architectural discussions, design reviews, and technical documentation including ADRs
- Mentor other engineers and raise the technical bar through code review and knowledge sharing
- Other duties and projects as assigned
Technical Environment
- Back-end: C#/.NET (ASP.NET Core, Entity Framework Core), .NET 10/.NET4.8, RESTful API design, WCF
- Front-end: Angular, TypeScript, Angular Material, MVC
- Cloud & Infrastructure: Azure (App Service, App Insights, Redis, Azure SQL, Docker, Azure AD), Kubernetes
- Data: SQL Server, LINQ, EF Core
- DevOps & Tooling: CI/CD pipelines, PowerShell, Git
Required Experience
- 5–7+ years of professional software development experience including both architecture and implementation
- Strong proficiency in C#/.NET and Angular for full-stack development
- Hands-on experience designing and consuming RESTful APIs and distributed, event-driven systems
- Deep understanding of secure coding practices, automated testing strategies, and CI/CD pipelines
- Experience with Entity Framework Core including query optimization, change tracking, and migration management
- Working knowledge of Azure cloud services
- Experience in code review as both author and reviewer, with a focus on quality, security, and maintainability
- Financial services or regulated-industry experience preferred
AI Fluency Expectations
This role requires daily, hands-on use of AI-assisted engineering. You are expected to:
- Use GitHub Copilot (IDE and CLI) as a default part of your development workflow
- Author and maintain structured context files (PRDs, design docs) that guide AI agents toward accurate output
- Orchestrate AI agents to generate code, scaffold tests, review pull requests, and identify defects
- Decompose complex work into planning and execution steps that AI can accelerate
- Exercise strong engineering judgment over all AI-generated output—AI is treated as a junior collaborator whose work you guide, review, and refine
Why This Role
- AI-native development is the standard, not an experiment—you will help define how modern software is built at enterprise scale
- Real architectural influence on a complex, production platform with legacy bridges, multi-service Azure infrastructure, and third-party integrations
- Engineers are trusted with system ownership, not just ticket execution
- Your work directly supports lending operations that serve real customers and carry real regulatory weight
