Job description

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. This next chapter is about scaling smart, powered by AI, a clear vision and real ownership.

Big tech impact, without the big tech ick.

• Innovate and implement well established practices for Platform Engineering.

• Design resilient and easy to use foundational infrastructure to support a growing customer base.

• Contribute to the strategy and design of engineering as a whole.

What you bring as an engineer

• Strong platform development background. You've built and shipped production systems, not just observed them with a proficiency in Go/Python and Terraform.

• Experience defining and implementing AWS managed solutions, utilising our strategic partnership to ship quicker.

• A track record of working across codebases and domains you didn't build - diagnosing issues, contributing improvements and establishing patterns others can follow.

• Comfort operating with all manner of customers, treating all members of staff as builders.

• Experience with architecture and system design, particularly in SaaS environments operating at scale.

• An attitude to do better and push others to do better .

What you bring as a senior engineer

• You lead through influence, not authority. You build consensus quickly, find the

fastest path forward through ambiguity and help teams make good decisions

without creating bottlenecks.

• You simplify complexity. Whether it's explaining a cross-domain failure mode to leadership or designing a pattern that replaces ad-hoc solutions across teams, you make things clearer and easier for others.

• You multiply the people around you - through coaching, pairing, code review and creating tools and documentation that raise the bar for everyone.

• You think in terms of the customer experience and the business, not just the system.

• You understand why reliability matters, not just how to achieve it.

• You adapt your approach to what's needed - sometimes that's deep technical problem-solving, sometimes it's aligning stakeholders, sometimes it's mentoring a mid-level engineer through a tough project.
