Job summary

Ottimate is seeking a capable software engineer to join as its third engineer, offering meaningful ownership and rapid growth. You will work on a mature financial platform, solving problems from product features to performance, security, and reliability while using AI-assisted development tools responsibly.

Key responsibilities include building backend features with Python/Django, reviewing AI-generated code for correctness, and ensuring data integrity and privacy across invoices and payments.

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.
