Description de poste

We are looking for a Senior Backend Developer to join a growing engineering team focused exclusively on building a new, enterprise-grade product. This is a product-only role (no client delivery or consulting work), where you’ll play a key part in translating architectural vision into robust, production-ready backend services. If you have the below requirements, please apply today!

  • Implement backend services under architectural guidance, contributing to foundational platform components
  • Build scalable, cloud-native services following established patterns, standards, and best practices
  • Develop calculation-heavy, deterministic business logic with a strong emphasis on correctness and repeatability
  • Design and optimize data pipelines and processing workflows
  • Maintain a high bar for code quality, testing, performance, and reliability
  • Collaborate closely with the Principal Architect on technical design decisions and implementation strategies
  • Write and maintain comprehensive unit and integration tests to support auditability and long-term maintainability

Key Challenges You’ll Tackle

  • Developing financial-grade, audit-sensitive systems
  • Handling complex data processing and transformation pipelines
  • Building performance-critical, deterministic logic
  • Creating foundational backend services that scale to enterprise-level customers
  • Required Skills & Experience

    Backend Development

  • 3–8+ years of experience in backend software development
  • Strong proficiency in .NET / C# (required)
  • Experience with strongly-typed, compiled languages
  • Frameworks & APIs

  • ASP.NET Core
  • Entity Framework Core
  • Background workers and async processing pipelines
  • RESTful API design and implementation
  • Databases

  • Strong experience with relational databases such as SQL Server / Azure SQL or PostgreSQL
  • Solid understanding of query optimization, indexing, and performance tuning
  • Cloud & Engineering Practices

  • Cloud-native development experience (Azure strongly preferred)
  • Experience building and supporting data pipelines
  • Strong testing discipline (unit, integration)
  • Performance profiling and optimization experience
  • Nice to Have

  • Message queues and asynchronous messaging
  • Docker and containerized workloads
  • CI / CD pipelines
  • Event-driven architectures
