Job DescriptionJob Description
We are seeking a Senior C# / .NET Developer to join a high-performing engineering team delivering complex, data-intensive software solutions. The role requires deep expertise in modern .NET development and a proven track record of building resilient distributed systems that operate at scale. This is a hands-on engineering position focused on technical delivery — designing, building, and maintaining backend services that are clean, reliable, and production-ready. The ideal candidate is pragmatic, quality-driven, and thrives in fast-paced environments where attention to detail and consistent execution make the difference.
Key Responsibilities
Design, develop, and maintain high-performance backend services and APIs using C# and modern .NET (.NET Core, .NET 5/6+) in a distributed systems environment
Build and evolve resilient, scalable microservices and event-driven architectures that handle large volumes of data reliably
Collaborate with cross-functional teams including architects, product managers, and QA engineers to define technical requirements and deliver solutions that meet business objectives
Ensure code quality through rigorous unit, integration, and performance testing, adhering to the team's Definition of Done and engineering standards
Participate actively in code reviews, architectural discussions, and technical decision-making, contributing to the continuous improvement of engineering practices
Identify, diagnose, and resolve performance bottlenecks, system failures, and technical debt in production and pre-production environments
Contribute to the design and implementation of data pipelines and processing workflows for large-scale datasets
Document technical designs, APIs, and system behaviors to ensure knowledge sharing and long-term maintainability
Requirements
Required Skills & Qualifications (Must-Have)
Undergraduate degree or higher in Computer Science, Engineering, Finance, or a related field
7+ years of hands-on software development experience with strong proficiency in C# and modern .NET frameworks (.NET Core, .NET 5, or .NET 6+)
Proven experience designing and building resilient distributed systems (microservices, event-driven architectures, message queues)
Demonstrated ability to work effectively with large volumes of data, including data processing pipelines and high-throughput systems
Commitment to writing high-quality, clean, maintainable, and well-tested code with a strong focus on readability and long-term supportability
Experience with RESTful API design and development, including integration with third-party services and internal platform components
Solid understanding of software engineering best practices: SOLID principles, design patterns, CI/CD pipelines, and version control (Git)
Deadline-driven, detail-oriented, and results-focused — consistently able to meet high quality standards while managing multiple concurrent tasks and priorities
Professional-level English proficiency (written and spoken) for client-facing communication and technical documentation
Soft Skills
Highly pragmatic and delivery-focused — driven by outcomes, not just technical elegance
Strong communicator capable of explaining complex technical concepts clearly to both engineering peers and non-technical stakeholders
Proactive in identifying risks, dependencies, and technical blockers, with a bias toward resolution
Collaborative team player who builds trust across distributed, cross-functional teams
Detail-oriented and organized, particularly around code quality, testing coverage, and technical documentation
Resilient and adaptable in fast-paced, complex delivery environments with evolving requirements
Preferred Qualifications / Nice-to-Have
Experience working in a Capital Markets or FinTech environment, with familiarity with financial data models or trading workflows
Background in Risk Systems and/or Pricing Model Integration
Passion for technology and large-scale software design, including interest in system architecture and engineering at scale
Hands-on experience with core Java and Spring Boot, or demonstrated willingness to learn and apply Java in a polyglot environment
Experience with Generative AI (Gen AI) tools, frameworks, or integrations within software products
Familiarity with cloud platforms (AWS, Azure, or GCP) and container orchestration (Docker, Kubernetes)
Exposure to nearshore or offshore delivery models with distributed international teams
