Job summary

Nexl in Sydney is seeking a Senior Software Engineer to help build our AI-driven CRM and growth intelligence platform. You will be technically rigorous and highly autonomous, with a high bar for what you ship and a strong point of view on architecture, security, and data modelling.

You’ll own end-to-end features across React/TypeScript and Ruby on Rails or Python, work with Claude Code and Cursor, and shape how an AI-first team ships fast while maintaining quality. Hybrid in Sydney hub.

Qualifications

• Deep expertise in full-stack software architecture, system design, data modelling, debugging, and security.
• Strong proficiency in React + TypeScript and strong proficiency in Ruby on Rails or Python.
• You use Claude Code, Cursor, or equivalent agentic tools as a primary development workflow, and can point to meaningfully higher output velocity as a result.
• Ability to critically assess AI-generated code for correctness, security, performance, and long-term maintainability. You know when to push back, refactor, or start over - and you do.
• Solid understanding of database design and optimisation (PostgreSQL, MongoDB) including indexing, query optimisation, and data modelling.
• Ability to take ownership, operate with minimal direction, and drive outcomes end-to-end, with a bias toward impact over activity.

Responsibilities

• Design and ship features end-to-end across React/TypeScript and Ruby on Rails or Python - from problem definition through architecture, implementation, testing, and release.
• Use Claude Code, Cursor, and similar agentic tools as a genuine development partner - structuring problems for AI execution, validating output, and building the shared AI workflows that make the whole squad faster, not just your own.
• Own system design, data modelling, security, and technical debt - the trade‑off calls that shape long-term platform health.
• Set and hold a high bar for code quality, including AI-generated code - reviewing for correctness, security, performance, and long-term maintainability, not just whether it runs.
• Own the reliability and scalability of what you ship - better observability, cleaner architecture, fewer production incidents over time.
• Work closely with your Tech Lead, Product Manager, and Design across every initiative - bringing technical depth and a clear point of view on what to build and how.
• Help the engineers around you raise their AI game - share what works (tools, prompting approaches, workflows) and make the whole team faster, not just yourself.
