Senior Fullstack Engineer
SafetyCulture · Sydney, Australia · 1mo ago
Why join us?
Mitti by SafetyCulture is a global tech company, just not the kind you're picturing. Our almost 1,000-person team builds tools that make work better for the three billion frontline workers who keep the world moving. We've got big tech scale, without the sign-off layers or corporate theatre. Every permanent team member gets equity, so when we grow, you do too. This next chapter is about scaling smart, powered by AI, a clear vision and real ownership.
Big tech impact, without the big tech ick.
The Role
This role exists to help build a new generation of industry-specific applications on top of the Mitti platform. You'll work in a small, fast-moving team with significant autonomy, building deeply tailored experiences for specific customer segments rather than extending a generic product flow.
Key Responsibilities
Design and build product features end-to-end across frontend, backend, and mobile, with a lean towards frontend and React Native
Make fast, pragmatic trade-off decisions about when to integrate with existing platform systems versus building independently
Navigate dependencies with platform teams — knowing when to contribute to shared infrastructure versus shipping what the team needs now
Partner closely with a principal engineer and cross-functional teammates to explore requirements, pressure-test technical approaches, and iterate quickly
Build AI-native features as the product matures, contributing to platform capabilities the broader engineering organisation can build on
Communicate trade-offs and constraints clearly so expectations stay grounded in engineering reality
Contribute to code review and help raise the technical bar through direct, collaborative engagement with peers
About You
Technical Skills
Strong frontend engineering capability with solid React experience; React Native experience is a strong advantage
Comfortable with backend development in TypeScript or Go — Go experience is a bonus, and the right person will pick it up with support
Experience building in product-focused, fast-iteration environments — ideally in a SaaS startup or scale-up
Able to build new applications while navigating and integrating with existing systems — comfortable working outside of greenfield environments
Actively uses agentic coding tools as a core part of how you work, not just occasionally
Product-minded: able to co-own direction with a product manager, make sensible scope calls, and understand the "why" behind what's being built
Behavioural Skills
Comfortable with ambiguity — picks up loosely defined requirements and drives towards a solution without waiting for a perfect brief
Assertive and direct: able to push back constructively, frame trade-offs clearly, and have honest conversations up and across the team
Fast and decisive: makes calls, ships, and course-corrects rather than over-engineering before moving
Collaborative without being passive — seeks to understand existing systems, debates trade-offs with peers, and lands on better outcomes together
Self-directed and hungry: identifies what needs doing and goes after it without close management
AI Skills
Uses agentic coding tools (such as Claude or similar) as a primary part of the development workflow
Able to prompt effectively, evaluate AI-generated code for quality and logical soundness, and apply human judgement where it matters
Curious about building AI-native product features and how AI is changing what's worth building
Success Looks Like
At 3 months: shipped meaningful features, made sound integration trade-offs, and built a strong working relationship with your principal engineer and team
Makes technical calls independently and confidently — escalates with options and trade-offs, not just problems
Keeps iteration cycles fast by unblocking independently and flagging real blockers early
At 6 months: features are in customers' hands, performing well, and you've contributed to how the team works — not just what it delivers
More than a job
Equity with high growth potential, and a competitive salary
Flexible working arrangements
Access to professional and personal training and development opportunities
Hackathons, Workshops, Lunch & Learns
In-house Culinary Crew serving up daily breakfast, lunch and snacks
Barista coffee machine, craft beer on tap, boutique wines and a range of non-alcoholic beverages
Wellbeing initiatives such as EAP services and generous parental leave policy
Quarterly celebrations and team events
On-site gym, table tennis, board games, books library, and pet-friendly offices
