Job description

We are CORTO, a cutting-edge software company dedicated to revolutionising the legal industry. Our mission is to empower legal practitioners with AI-driven solutions that streamline their workflow, boost productivity, and provide more efficient client service.

Our team of AI experts and engineers collaborate to develop intelligent software tailored to the unique needs of lawyers, paralegals, and legal assistants. Our innovative AI solutions automate routine tasks, simplify document management, and enhance decision‑making, allowing legal professionals to focus on what they do best—providing expert legal counsel.

We’re rapidly scaling from 80 to 250+ employees, with a highly technical workforce where around 75% of the team are developers and engineers. Working alongside our Sydney‑based team of passionate high achievers, you’ll join a fast‑growing technology business where things rarely stay the same for long - and if you’re smart, caring, and ambitious, you’ll be in great company.

What you’ll do

You’ll be joining the Content Systems team, where we’re building the legal data backbone that powers our products across law firms and legal‑adjacent industries.

We’re looking for a Software Engineer to own the front end of the application, our in‑house application our content designers use to build and maintain the legal templates and forms across multiple countries. It’s a mature, business‑critical product with real users who rely on it every day, and there’s plenty to improve.

You’ll own UI features end to end, from understanding a request and designing the solution through to release, and you’ll shape how the application looks and behaves.

To make this happen you will

• Design, build and maintain front‑end features for LEAP Design, from UI design through to release
• Turn designs and user feedback into intuitive, accessible, polished interfaces
• Keep the UI fast and responsive with sound async and state management
• Structure UI code with clear patterns (MVVM, component‑based architecture) and reusable components
• Lead technical design, review code and set standards for testing and maintainability
• Identify and pay down technical debt in an established codebase

What you’ll bring

• 5+ years of professional software development, with a strong focus on front‑end or UI engineering
• Deep experience with at least one modern UI framework (Blazor, WPF, Win UI, .NET MAUI, WPF)
• Strong programming skills in ,NET C#
• Habit of writing the unit tests and clean, maintainable code
• Clear written and verbal communication
• Even better if you have WPF and XAML with MVVM: a strong bonus

You are the type of person who

• Thinks beyond the ticket. You dig into what users actually need and come up with the best solution, rather than just building what’s asked.
• Enjoys the design side of engineering, mapping out the approach before writing the code.
• Picks up new things quickly, whether that’s a complex product, a new domain like legal, or an unfamiliar framework.
• Takes pride in clean, well‑tested code and follows good engineering practice (design, code reviews, unit tests) without needing heavy process.
• Is comfortable working in an established codebase and gets satisfaction from making it faster and better.

CORTO is an inclusive, people‑first company committed to breaking down institutional barriers that keep people from reaching their potential. If you meet some, but not all the requirements above, we encourage you to still submit your application.

• Your work matters. We solve real world problems that improve and support local, everyday law firms. So they can do their best work for the people in the communities they serve.
• Make an impact. You won’t be another ‘cog in the wheel’ here. We give full trust and autonomy for you to be heard, to work on big & complex projects – and to make a real difference.
• Work with a group of authentic, passionate people who love what they do.
• Well‑funded and global. CORTO is part of ATI Global – one of the largest international LegalTech companies.
• Flexible and hybrid working. We engage, share, and collaborate on ideas and workflows.
• Career and learning opportunities - we move fast and need smart people to get us where we're going. We are a scaling business and looking for people who want to grow with us.
• Have fun with us. Celebrations. Socials. Sports teams. Access to sailing and yacht events.
• We value your well‑being with additional time off, gym membership and other perks.
• Fast‑paced tech environment, if we don't disrupt ourselves someone else will do it!
• Access to LEAP Home - a program unique to the ATI Group to support you in buying your primary residence.
