CORTO
Software Engineer
Posted: 30 April
Offer description

Overview

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 150+ employees, with a highly technical workforce where around 90% 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

This is a greenfield .NET and AI build. You'll join our Accounting Backend team to design and ship a new platform from the ground up for CORTO's next-generation billing and accounting products. Working closely with the Head of Backend Engineering, you'll make the early calls that shape the whole system: domain design, database modelling, fast-at-scale queries, and how we embed LLMs deep into the backend to generate, transform and enrich information in ways that genuinely hold up in production. A rare chance to own the foundations of a core product, with real technical autonomy.

What you'll bring

* 5+ years building production systems with ASP.NET Web API (C#/.NET)
* Deep experience with distributed systems, RESTful APIs and relational databases (4+ years)
* Ability to integrate LLMs into backend systems to enable automated information generation, transformation, and enrichment.
* Strong grasp of SOLID principles and clean architecture
* Hands-on experience with AWS (or equivalent cloud) in production
* Track record of performance tuning and designing for scale
* Experience mentoring engineers and lifting team technical standards
* Pragmatic - you know when to ship fast and when to slow down and get it right

You are the type of person who

* Takes ownership end-to-end - you don't stop at the API boundary
* Cares as much about reliability and observability as you do about shipping new features
* Enjoys teaching and is generous with your technical knowledge
* Asks why before you ask how
* Is curious about AI and how it can reshape the software we build

Why join CORTO

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.
