Senior Software Engineer (React + .NET)
We are hiring a Senior Software Engineer to help rebuild a complex legacy financial application as a modern, modular platform. This is a greenfield engineering role focused on re-creating core functionality with feature parity first, while building a clean foundation for future enhancements. This role is best suited for a senior full stack engineer who is highly autonomous, comfortable working from specifications and collaborative requirement discussions rather than detailed feature tickets, and capable of understanding both user-facing workflows and backend business logic.
The team works in a facilitated, outcome driven model internally referred to as JADx, an extended version of Joint Application Development (JAD), where engineers engage directly in clarifying workflows, business intent, and expected outcomes before translating them into working software. This is an AI-enabled engineering environment, and we are looking for engineers who already use these tools effectively to author a meaningful portion of their code, accelerate iteration, and improve productivity while maintaining accountability for correctness, maintainability, and technical quality.
Key Responsibilities
- Design and deliver full stack functionality that advances the rebuild of the legacy platform with feature parity and modern architecture.
- Build responsive, maintainable frontend experiences in React and scalable backend services in .NET.
- Translate specifications, collaborative requirement sessions, business scenarios, and observed legacy behavior into working software with limited task-level direction.
- Participate actively in JADx, an extended version of Joint Application Development, to clarify workflows, identify edge cases, and align implementation to business outcomes.
- Analyze the legacy application to understand validations, dependencies, workflows, and hidden complexity that must be preserved in the rebuild.
- Contribute to a modular architecture that supports maintainability, quality, future extensibility, and effective deployment in cloud environments.
- Make sound implementation decisions independently and help reduce ambiguity for the broader team.
- Collaborate closely with engineering leadership, peers, and QA to deliver in a fast-iteration, outcome-focused environment.
- Use AI-assisted development tools as a core part of the engineering workflow for coding, prototyping, refactoring, and technical exploration.
- Maintain strong standards for code structure, readability, testability, maintainability, and operational readiness.
Required Qualifications
- Bachelor’s degree in Computer Science, Engineering, or a related field (Must have "Titulo" or in process of obtaining with 100% credits)
- Strong experience developing backend services and APIs with .NET / C#.
- Strong SQL skills, including schema understanding, querying, and effective use of relational databases such as SQL Server.
- Proven ability to deliver across frontend, backend, integration, and application runtime concerns.
- Experience working in modular or service-oriented architectures.
- Practical knowledge of cloud platforms such as Azure and/or AWS, including deploying applications, working with managed services, configuration, logging, and basic security considerations.
- Ability to work effectively from high-level requirements, collaborative workshops, and business outcomes without relying on highly detailed backlog tickets.
- Experience learning from or reverse-engineering existing systems to support new development.
- Strong written and verbal English communication skills.
- Strong ownership mindset and ability to operate independently in a senior team environment
