About this job
Job Description
Coderio designs and delivers scalable digital solutions for global companies. We combine strong technical expertise with a product mindset to lead complex software initiatives end-to-end. We work with international clients, value autonomy and clear communication, and build long-term partnerships through technical excellence.
The Project
We are looking for a Senior Full-Stack Engineer to join a three-person team at a leading financial institution. The project replaces a legacy system of 16 workflows: a web portal where branch users submit requests, and a backend that sends them to other systems, receives responses, updates statuses and manages approvals. Delivery dates are aggressive, so we need someone who can contribute quickly after onboarding.
Responsibilities- Design and build backend services in C# / .NET, applying clean architecture and engineering best practices.
- Deliver features end to end: APIs, integrations with other systems, approval-workflow logic and the React web portal.
- Work in an Agile team with two-week sprints and the usual ceremonies.
- Answer teammates' technical questions and take part in code reviews.
- Write and maintain unit and regression tests.
- Document technical decisions and collaborate with business stakeholders and teams that own other systems.
- 5+ years of hands-on software development experience in C# / .NET (7+ preferred), building applications rather than only maintaining them.
- Applied knowledge of clean architecture: SOLID principles, separation of concerns (SRP), DRY and domain-driven design.
- Proven experience building an application from scratch.
- Working knowledge of React and CSS (no UI design specialization required).
- Experience writing unit and regression tests.
- Experience working in Agile / Scrum teams.
- Strong in-person communication, teamwork and the ability to adapt to a corporate environment.
- Ability to work in a hybrid model from the Miami Lakes, FL office.
- Professional level of English [confirm with the client].
- Experience in banking or financial services.
- Experience integrating systems through REST APIs and messaging.
- Experience with workflow and approval processes.
- Familiarity with UI templates such as Mantis.
- A genuine passion for programming and for tackling a challenging, high-volume project.
- Hybrid collaboration in a dynamic and fast-paced environment in the Miami / Fort Lauderdale area.
- Long-term contract engagement with high impact and autonomy.
- Strategic and high-visibility role within a modern engineering culture.
- Opportunity to influence technical strategy, especially regarding modern event-driven architectures and AI integrations.
- Collaborative international team with strong technical leadership.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
