Software Engineer, Full Stack Developer, Backend Developer

About UsAt Immutable, our mission is to drive the next evolution of gaming. One of the hardest part of gaming is finding the players it deserves. Thousands of games launch every month, most never reach the audience they've already earned. That's the problem Immutable exists to solve, and it's why we built Audience, our growth platform for game studios. We're growing faster than we ever have, and we're hiring the talent who'll take it further.

Founded in 2018 and headquartered in Sydney, Australia.

A bit about the role

Immutable is looking for a hands-on product engineer to build Audience, the Mar Tech platform that decides whether a game succeeds. This role sits at the intersection of engineering, product, and data and you'll own outcomes, not just tasks. The work spans multiple initiatives including attribution and measurement (built from scratch, so studios can see which marketing actually drives players), engagement (a lifecycle and messaging engine built for games), AI growth (an AI CMO that audits a studio's marketing and recommends the next best action) and more.

You’ll Be Empowered To (responsibilities)

• Own features end to end, from the customer problem through to shipping into a live product used by paying game studios
• Build attribution and measurement such as, click tracking, identity capture, install attribution, and conversion postbacks that work natively
• Shape Engage, our lifecycle and messaging engine across campaigns, journeys, segmentation, deliverability, and A/B testing
• Help build our AI CMO, and the orchestration layer that lets it beat a generic model by encoding real marketing expertise
• Work AI-native by default, using Cursor, Claude Code, and our own coding agents in the pull-request loop
• Work directly with Product, Design, Data, and our founders, and talk to the studios using what you build

• 4+ years of engineering experience in a product-driven environment
• Energised in an ambiguous environment
• Strong hands-on experience with Type Script (both frontend and backend) and Golang is a must have
• Empathy-driven communication and the ability to work across varied stakeholders
• Experience mentoring and sharing best practices with junior engineers
• Passion for user-first product development and operational excellence
• Start-up or Entrepreneurial experience is a plus
• Keen interest in Gaming and a willingness to learn fast

• Have built product at a marketing, growth, attribution, customer-data, or customer-engagement company, and terms like segments, attribution, user acquisition, CDP, CEP, lifecycle, and deliverability are second nature
• Have taken a product from 0 to 1, defining the first version and cutting scope yourself, and you think customer-problem-first
• Build with AI agents day to day, and have real opinions about where they help, where they don't, and when not to trust them
• Building and shipping AI or LLM-powered product features

• Type Script, Go, Next.js and React, a Big Query-based customer data platform, AWS and GCP, Kubernetes, and AI tooling including Cursor and Claude Code.
• We track our work in Linear.

Small teams that own their outcomes. Fast iteration on CI/CD rather than big-bang releases. AI does the mechanical work so you can focus on judgement, taste and the customer.

The strongest candidates often bring an unexpected background, and we'd rather hear from you than have you rule yourself out. We build for a global community of players, and we want a team that reflects it.

• We commit to paying globally competitive base salaries and contributions to a long-term fund
• Sharing our products' success through Employee Stock Options ESO
• Our flexible working model blends the best of both…
