Job summary

VenueSumo Pty is seeking a senior hands-on engineering lead to design, build and ship features end to end across .NET, SQL Server, and modern web front ends. You will own the Azure infrastructure, lead architecture discussions with leadership, and mentor engineers as the platform scales across three continents.

You will modernise a mature codebase, implement infrastructure as code, and run CI/CD pipelines using Azure DevOps or GitHub Actions while ensuring security, observability and cost

Qualifications

• 8+ years in software engineering, including time as a lead or senior engineer setting technical direction for a team
• Strong full stack skills: C#/.NET and SQL Server (T-SQL), plus modern web front ends (JavaScript/TypeScript; React or similar)
• Proven hands-on experience designing, building and running production infrastructure on Microsoft Azure
• Infrastructure as code and CI/CD pipelines (Azure DevOps or GitHub Actions)
• Solid knowledge of Azure networking, identity and security (virtual networks, Microsoft Entra ID, Key Vault, managed identities), and monitoring with Azure Monitor and Application Insights
• Experience with performance tuning, scaling, high availability and disaster recovery for a production SaaS platform
• Experience designing APIs and integrations at scale, and modernising a mature codebase while it keeps serving customers
• Deep, current hands-on use of AI coding tools, paired with the judgement to know where AI helps and where careful thinking matters more

Responsibilities

• Design, build and ship features end to end: C#/.NET services and APIs, SQL Server, and modern web front ends
• Own your work from first prototype to production, including testing, release and support
• Work with Product to turn ideas into working prototypes in days, then harden them into production features
• Take on the hardest technical problems: performance, data integrity, reporting and complex business logic
• Fix customer-raised issues quickly and at the root cause, not just the symptom
• Own the Azure environment our platform runs on: compute, databases, storage, networking, CDN and identity
• Define infrastructure as code so every environment is repeatable and version controlled
• Build and run CI/CD pipelines (Azure DevOps or GitHub Actions) that let us ship small changes safely and often
• Make the platform observable, with monitoring, logging, alerting and incident response using Azure Monitor and Application Insights
• Lead on reliability, scalability, backup and disaster recovery, and on multi-region readiness as we grow across Australia, North America and the UK

Job description

About us

VenueSumo is the all-in-one POS, online ticketing and venue management platform for family entertainment centres, amusement parks and attractions. Venue operators run their whole business on us: bookings and ticketing, point of sale, waivers, memberships, CRM, payments, gift cards and more. We're an Australian-born SaaS scale-up growing fast across Australia, North America and the UK. We've just closed a growth equity round, and we're investing it in the team and the product. Our ambition is big: to make VenueSumo the leading AI-native operating system for leisure and attractions, where intelligent automation handles the busywork and operators spend their time on guests.

About the role

You'll be one of the most senior hands-on engineers at VenueSumo. You'll build features end to end across our .NET backend, SQL Server data layer and web front end, and you'll own the Microsoft Azure infrastructure they run on. As a technical lead, you'll set the bar for code quality, lead the technical design of major features and integrations, and mentor the engineers around you. You'll work closely with our Head of Engineering and CTO on architecture and on modernising the platform. You'll also make our cloud platform resilient, secure, observable and cost-efficient as we scale across three continents. Above all, we're looking for a systems thinker and an innovative problem solver. You'll use the best AI development tools every day, but AI is there to amplify great engineers, not to do the thinking for them. We want someone who understands problems deeply, sees how the pieces of a complex platform fit together, and designs solutions that last.

Key responsibilities

• Design, build and ship features end to end: C#/.NET services and APIs, SQL Server, and modern web front ends
• Own your work from first prototype to production, including testing, release and support
• Work with Product to turn ideas into working prototypes in days, then harden them into production features
• Take on the hardest technical problems: performance, data integrity, reporting and complex business logic
• Fix customer-raised issues quickly and at the root cause, not just the symptom
• Own the Azure environment our platform runs on: compute, databases, storage, networking, CDN and identity
• Define infrastructure as code so every environment is repeatable and version controlled
• Build and run CI/CD pipelines (Azure DevOps or GitHub Actions) that let us ship small changes safely and often
• Make the platform observable, with monitoring, logging, alerting and incident response using Azure Monitor and Application Insights
• Lead on reliability, scalability, backup and disaster recovery, and on multi-region readiness as we grow across Australia, North America and the UK

About you

• A systems architect's mindset. You think about how a whole platform fits together (data, services, integrations and infrastructure) and design for scale, resilience and change
• A track record as an innovative problem solver: you break down complex, ambiguous problems, weigh the trade-offs and find elegant solutions
• 8+ years in software engineering, including time as a lead or senior engineer setting technical direction for a team
• Strong full stack skills: C#/.NET and SQL Server (T-SQL), plus modern web front ends (JavaScript/TypeScript; React or similar)
• Proven hands-on experience designing, building and running production infrastructure on Microsoft Azure
• Infrastructure as code and CI/CD pipelines (Azure DevOps or GitHub Actions)
• Solid knowledge of Azure networking, identity and security (virtual networks, Microsoft Entra ID, Key Vault, managed identities), and monitoring with Azure Monitor and Application Insights
• Experience with performance tuning, scaling, high availability and disaster recovery for a production SaaS platform
• Experience designing APIs and integrations at scale, and modernising a mature codebase while it keeps serving customers
• Deep, current hands-on use of AI coding tools, paired with the judgement to know where AI helps and where careful thinking matters more

Benefits

• A senior, hands-on lead role in a freshly funded, fast-growing SaaS business
• Real influence over our architecture, our infrastructure and how we build the leading AI-native operating system for leisure and attractions
• A generous budget for the best AI tools. No waiting for approval to try what's new
• Competitive salary
• A Gold Coast office at Mermaid Beach, or remote from anywhere in Australia or New Zealand
• A small team of highly talented senior developers who ship fast and work close to the venues that use our software every day
