Sydney, New South Wales, Australia The Onset Full time

Join to apply for the Backend Engineer role at The Onset

Overview

At some places, engineering feels like ticking boxes. Here, it feels like impact. This is your chance to join a team expanding its product and engineering footprint into Sydney, where new incubation squads are being built to focus on 0→1 product innovation in marketing and loyalty. Think startup speed inside a scale-up: small, autonomous, customer-obsessed teams with the mandate to rapidly test, build, and scale new products that will shape how venues connect with, retain, and grow their guest communities. This is your chance to work on modern tech that powers real-world experiences millions of people enjoy every year. Think ticketing, payments, memberships, POS – but re-imagined for entertainment, attractions, and fun.

What You'll Be Working With

C# .NET 6+, SQL Server, AWS (Lambda, API Gateway, DynamoDB, S3, SQS)

Plus the freedom to explore new and emerging tech that can make life better for both customers and engineers.

Why You'll Love It
  • You'll be trusted to design, build, and own solutions that directly help customers create unforgettable guest experiences.
  • You won't be boxed in, experimentation and curiosity are encouraged, with space to try new things and learn from them.
  • You'll grow alongside a smart, down-to-earth team who raise the bar and keep it real.
  • Hybrid rhythm: 2-3 days in a central Sydney office, 2-3 days from home - balance included.
  • Growth baked in: personal L&D budget, opportunities to stretch into new challenges, and a team that actually wants you to thrive.
The Vibe

The team is 180+ humans across 30+ countries, united by a shared obsession with building technology that helps others create joy. Values aren't laminated posters here – they're lived every day. From "make it happen" to "go together," it's about doing great work while enjoying the ride.

The Perks
  • Extra "Recharge Days" every year (the whole company switches off together)
  • 16 weeks paid parental leave for primary carers
  • Wellbeing support through coaching, webinars, and resources
  • A "Vibe Tribe" that drives socials, fundraising, and all-round good times
Responsibilities


• Design, build, and own solutions that directly help customers create unforgettable guest experiences.
• Collaborate with incubation squads focused on 0→1 product innovation in marketing and loyalty.
• Contribute to a modern tech stack powering experiences in entertainment, venues, and related spaces.
• Embrace experimentation and learn from outcomes to continuously improve product quality and impact.

Qualifications


• Experience with C# and .NET 6+; SQL Server; and AWS services (Lambda, API Gateway, DynamoDB, S3, SQS) is preferred.
• Ability to work in a hybrid setup with Sydney-based teams.
• Strong problem-solving and collaboration skills, with customer-obsessed thinking.
