Sobre el cargo

• We are looking for a Senior .NET Backend Engineer to help build a modern, distributed platform for tax preparation software. You will work across backend services, business rules, asynchronous workflows, and financial data integrity while helping rebuild the core system with modern .NET and AWS. This role requires strong ownership. You will investigate ambiguous requirements, understand tax and business rules, define technical solutions, evaluate trade-offs, and drive implementation with limited supervision. You will also support production incidents during tax season and use AI-assisted engineering tools responsibly, validating their output before delivery.

Qué harás

• Clarify business problems with Product and stakeholders, investigate legacy behavior, and define clear acceptance criteria.
• Design and build backend services, including website and calculation APIs that communicate through asynchronous workflows.
• Develop reliable distributed processing with concurrent workers, duplicate and out-of-order messages, retries, dead-letter queues, and exactly-once effects on tax and financial data.
• Create technical plans that explain risks and trade-offs, secure approval, and drive implementation through production.
• Use Claude Code as part of daily engineering work, reviewing and validating generated solutions for correctness, security, and maintainability.
• Troubleshoot production incidents and help maintain service reliability during tax season.

Qué pide la empresa

• Senior backend engineer with 8+ years of software development experience, including 4+ recent years with modern C#/.NET.
• C1 English level or higher.
• Strong practical knowledge of async/await, dependency injection, concurrency, background workers, and .NET troubleshooting.
• Advanced Entity Framework Core and Dapper experience, including tracking, DbContext lifetime, and transactions.
• Hands-on experience with distributed systems, messaging or queues such as AWS SQS, idempotency, retries, consistency, and failure handling.
• Experience with CQRS, Redis, AWS and relational databases, preferably PostgreSQL.
• Proven ability to own technical decisions and deliver projects end to end.
• Hands-on experience with Claude Code or similar AI coding agents, including context management, subagents, token usage, and output validation.
