Sobre

Overview We’re a US-based fintech vendor building digital statement and document-delivery platforms for banks and credit unions. We’re big on digital delivery and workflow optimization at scale. Our stack is modern C#/.NET Core, and we lean hard on AI to move fast without getting sloppy. Front end work is part of the role — we’re modernizing the UI and are currently evaluating Angular vs React. We’re hiring a senior C#/.NET Core engineer for a full-time, long-term role. This is production work on systems that handle high-volume document generation and digital delivery. We need someone who writes clean, reliable code, can think through edge cases, and communicates clearly in a remote setup. Because our platform supports institutions handling sensitive customer data, we take security seriously. Work will be done using anonymized/synthetic data. What you’ll work on * Build and improve backend services and web apps in C#/.NET Core (MVC + Web APIs). * Help modernize and evolve our digital delivery web UI (Angular or React). * Enhance workflows that generate, process, and deliver customer documents digitally. * Improve reliability across pipelines: validation, logging, error handling, monitoring, and edge cases. * Performance tuning for high-volume, structured data and document runs. * Help keep internal documentation clear and usable as we go. Tech stack (high level) * C# / .NET Core / ASP.NET MVC / Web APIs * JavaScript / TypeScript (front end modernization; Angular vs React evaluation in progress) * SQL-based data stores * AWS infrastructure and monitoring * AI-assisted development workflow (used daily) Tools we use: Git, Azure DevOps, Jira, Confluence, CI/CD, AWS monitoring (CloudWatch/NewRelic). What we’re looking for Must-haves: * Strong production experience with C# and .NET Core. * Solid ASP.NET MVC / Web API background. * Comfortable working across backend and front end (Angular or React experience is a plus). * Practical engineering habits: thoughtful logging, validation, testing, and performance awareness. * Clear communicator in a remote setting. * Dependable delivery and follow-through. Nice-to-haves (not required): * Python for internal tools/automation * Experience with fintech/banking, digital delivery, or document processing * Workflow orchestration / batch or high-volume processing experience * UI modernization experience in Angular and/or React Engagement details * Full-time (40 hrs/week), long-term * Remote / async-friendly with overlap for key discussions * Start: ASAP * We ask for focus during agreed working hours (no competing fintech clients during active engagement). If downtime ever occurs on our side, we handle it explicitly and fairly. How to apply Please include: * A short summary of relevant .NET Core / MVC work you’ve done. * 1–2 examples of similar systems you’ve built/maintained (backend services, workflows, high-volume platforms, etc.). * An example of front-end work you’ve done and which framework(s) you used. * Your time zone and typical working hours. * Any experience related to digital delivery, documents, or workflow automation. If it looks like a fit, we’ll do a quick call and then a short paid trial period to confirm mutual fit before going fully long-term.
