Job Description
Senior Software Engineer (AI-Native Development)
At Benivo, we believe the next generation of strong software engineers will combine deep engineering judgment with the ability to orchestrate AI agents to design, implement, test, and ship software faster.
We are hiring a Senior Software Engineer (AI-Native Development) to help us build software significantly faster and better using tools such as Codex, Claude, GitHub Copilot, and similar tools.
This is not an AI/ML or research role. It is a hands-on software engineering role for someone who can use AI effectively across the full development lifecycle while remaining fully responsible for quality, design, maintainability, security, and production outcomes.
What you will do
- Build new product capabilities from requirements through release
- Work confidently inside a large, evolving codebase with technical debt and business-critical logic
- Set up and use multiple AI agents or agentic workflows to accelerate requirements analysis, implementation, testing, refactoring, unit testing, and documentation
- Review and strengthen AI-generated output rather than relying on it blindly
- Write maintainable, production-grade code and automated tests
- Make sound technical decisions across architecture, performance, security, and maintainability
- Help raise the bar for AI-native engineering practices across the organisation
What we value
Strong engineering fundamentals
Ability to produce significantly more engineering output by orchestrating AI tools effectively, not simply writing code faster manually
High ownership
Fast execution with quality
Sound judgment
Comfort operating in real production complexity
Business-result orientation
Experience building and shipping production software
Demonstrated ability to design effective prompts, agent workflows, and AI-assisted development processes using tools such as Codex, Claude, Copilot, Cursor, or similar systems
Experience structuring sophisticated engineering tasks so that AI agents can execute them effectively
Ability to evaluate, debug, and refine AI-generated outputs through prompt iteration and workflow design
Experience in both creating new systems and improving established ones
Strong understanding of APIs, databases, testing, debugging, and system design
Experience setting up and operating multiple AI agents or agentic workflows across requirements analysis, code generation, refactoring, code review, testing, refactoring, unit testing, and documentation
Strong ability to evaluate code quality, correctness, and security
Ability to work independently and take responsibility for outcomes
Preferred background
- Experience with C# / .NET, React, APIs, and automated testing
- Experience in SaaS product companies
- Experience with CI/CD and modern development workflows
- Experience with legacy code modernisation
- Experience in improving engineering productivity across a team
