Role Summary

We’re looking for a rare kind of engineer.

Someone with over 20 years of software engineering experience who is still writing code every day. Someone who embraces AI as an engineering partner, not just a productivity tool. Someone who can architect complex systems, build production software, mentor teams, and continuously redefine what’s possible with modern software development.

This is not a management role. This is a hands-on technical leadership role for an exceptional software engineer who leads through technical excellence, curiosity, and execution.

If you are passionate about AI-native engineering, modern development practices, mobile innovation, and solving complex business problems through software, we’d love to hear from you.

Responsibilities

  • Design and build enterprise-grade software solutions from concept through to production.

  • Define architecture across cloud, backend, web, AI and mobile platforms.

  • Develop production-quality software using AI-assisted engineering workflows.

  • Build intelligent applications powered by Large Language Models (LLMs), AI agents and modern AI platforms.

  • Design and develop native mobile applications (iOS and Android) and cross-platform solutions using Flutter or similar frameworks.

  • Partner with clients and engineering teams to solve complex technical challenges.

  • Mentor senior engineers and influence engineering standards through hands-on technical leadership.

  • Evaluate and introduce emerging technologies that improve engineering capability and business outcomes.

  • Continue coding, prototyping and experimenting with new technologies as part of your daily work.

Qualification Experience

  • Bachelor's degree in Computer Science, Information Systems or related field preferred

  • 20+ years of professional software engineering experience.

  • Proven experience designing and delivering complex software systems at enterprise scale.

  • Strong architecture capabilities with the ability to translate strategy into working software.

  • Expert-level coding skills and a passion for remaining hands-on.

  • Extensive experience building cloud-native applications using Azure, AWS and/or Google Cloud.

  • Deep knowledge of modern software architecture, APIs, distributed systems, DevSecOps, CI/CD and secure software engineering.

  • Experience developing native mobile applications using Swift and/or Kotlin.

  • Experience with cross-platform mobile development using Flutter or comparable technologies.

  • Strong consulting and stakeholder engagement skills.

  • Experience working within Agile / SAFe / hybrid delivery models, aligned to strong governance and reporting expectations

  • Proven ability to manage and balance technical quality, delivery pace, and operational stability

  • Experience collaborating closely with:

  • Product Owners and Business stakeholders

  • Architecture, Security, and Platform teams

  • UX / Experience Design and QA functions

  • Strong exposure to DevSecOps, CI/CD pipelines, and production release governance

  • Experience operating in multi-vendor or partner environments, with accountability for engineering outcomes.

AI-Native Engineering Experience

You should already be comfortable building software using modern AI development practices and be familiar with technologies such as:

  • Cursor

  • Claude Code

  • GitHub Copilot

  • OpenAI Codex

  • Windsurf

  • Gemini Code Assist

  • Lovable

  • new

  • Firebase Studio

  • Other emerging AI engineering platforms

  • AI agents and agentic workflows

  • Retrieval-Augmented Generation (RAG)

  • Model Context Protocol (MCP)

  • Function calling and tool integration

  • Prompt engineering

  • Vector databases

  • AI application evaluation and governance

The Person We’re Looking is someone that:

  • Loves writing great software.

  • Learns new technologies before they become mainstream.

  • Is energised by solving difficult technical problems.

  • Thinks strategically but delivers practically.

  • Challenges conventional thinking with evidence and working solutions.

  • Mentors others through collaboration rather than authority.

  • Has a strong sense of ownership and accountability.

  • Is excited about shaping the future of software engineering through AI.

Desirable Experience

  • Multi-agent AI systems

  • Edge AI

  • On-device AI

  • React Native or .NET MAUI

  • Developer Experience (DevEx)

  • Open-source contributions

  • Conference speaking or technical writing
