Software Engineer II - Backend, CIAM

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.

As a Software Engineer II in the Customer Identity and Access Management (CIAM) team, you deliver well-scoped services and features inside an architecture our Senior and Staff engineers set, and grow real depth in the identity domain as we modernise the platform.

You will work with a modern tech stack including Golang on the backend, identity and access technologies such as OpenID Connect and Security Assertion Markup Language (SAML), Amazon Web Services (AWS) , Auth0 and Kafka for infrastructure, and datastores such as PostgreSQL.

Key Responsibilities:

• Design, build and maintain backend services in a large-scale software-as-a-service platform, including distributed systems and data stores.

• Take ownership of features from inception to delivery, collaborating with product, design and other engineers.

• Build and maintain authentication and user lifecycle flows - signup, login, multi-factor authentication and single sign-on and user orchestration - and grow real depth in the identity domain.

• Contribute to safe, incremental migration off legacy identity services using feature flags, backwards compatibility and staged rollout.

• Treat security as part of the craft: handle credentials and tokens carefully, and raise concerns early rather than working around them.

• Participate actively in code review, testing and the continuous improvement of our engineering practices.

• Make foundational capability easy for other engineering teams to consume, treating them as the customer of platform work.

• Demonstrate SafetyCulture's values - Think Customer, Open Honest Always, Better as a Team, Be Bold Bring Action.

Required Skills and Experience:

Technical skills:

• Solid capability in back-end programming languages and frameworks, with growing expertise in building scalable systems; prior experience with Golang is highly desirable.

• Practical experience owning and delivering software features end to end in a collaborative environment.

• Relational data modelling and PostgreSQL - sound schema design, safe migrations, and the ability to reason about indexing and query cost.

• Familiarity with cloud platforms such as AWS, including deploying, operating and debugging your own services in production.

• An understanding of distributed systems concepts - application programming interface design, retries, idempotency, timeouts and eventual consistency.

• Exposure to authentication, sessions or identity - login and signup flows, token handling, or standards such as single sign-on, OpenID Connect, OAuth 2.0 or SAML. Depth here is welcome but not required; appetite to go deep is.

• Experience in multi-tenant systems where organisation and membership boundaries have to hold under scale and change.

• A commitment to writing clean, maintainable, well-tested code, and to giving and receiving code review well.

Behavioural skills:

• Self-direction on well-scoped problems - takes a defined problem and drives it to done without daily direction.

• Good judgement about when to push on and when to ask; raises risks and blockers early rather than burning a week.

• Works effectively with product, design and engineers on other teams, and can explain a technical constraint to someone non-technical.

• Builds for others, not just for self - cares whether what they ship is easy for the next team to consume.

• Comfort working in a domain that is being actively re-architected around them, and with priorities that shift.

Artificial intelligence skills:

• Uses artificial intelligence coding assistants as a normal part of the working day, and can critically evaluate what they generate for correctness, quality and security.

• Identifies practical opportunities to apply automation or intelligence within feature development.

• Minimum expected: hands-on daily use with informed scepticism. Not expected at this level: defining tooling, guardrails or adoption patterns for other teams.

We're committed to building inclusive teams and cultivating a sense of belonging so our people can bring their whole authentic selves to work each day. We seek to make reasonable adjustments throughout our recruitment process to create an even playing field for all candidates. Thanks to the tireless efforts of the entire Mitti team we've built an incredible culture which has seen us recognised as a Best Place to Work in Australia , the US and the UK .
