Qualifications

• Professional software engineering experience at an early-to-mid-career level.
• Strong working knowledge of Python
• Experience designing, querying, and debugging applications backed by relational databases
• Familiarity with APIs, automated testing, Git, and collaborative software-development practices
• Experience using AI-assisted coding tools in real development work
• The ability to evaluate and validate generated code rather than accepting it automatically
• Strong debugging skills, including in an unfamiliar codebase, and the habit of asking what a bug did to customer data, then helping correct it
• An understanding of common application concerns such as authorization, concurrency, retries, idempotency, and failure handling
• Clear written and verbal communication
• A careful approach to systems that handle sensitive business and financial data
• Comfort working on a small team with broad ownership and changing priorities
• Curiosity, humility, and a willingness to ask questions, receive feedback, and learn new systems

Responsibilities

• Build, test, and maintain backend product features, primarily using Python, Django, and relational databases
• Use AI coding tools to investigate problems, implement changes, write tests, and improve documentation
• Critically review AI-generated code for correctness, security, performance, and maintainability
• Turn customer feedback into reproducible technical problems, fix the root cause, check whether customer data was affected, and update it
• Translate ambiguous customer feedback into reproducible technical problems and practical product improvements
• Own work from initial investigation through implementation, testing, QA, deployment verification, and follow-up
• Build and maintain APIs, asynchronous jobs, integrations, internal tools, and data-processing workflows
• Write clear, maintainable code with appropriate automated test coverage
• Participate in code reviews and technical discussions with the rest of the engineering team
• Improve system reliability, observability, documentation, and development processes
• Protect financial correctness, tenant isolation, data integrity, auditability, and customer privacy
• Gradually take ownership of larger features and technical decisions as you grow in the role
