Senior Software Engineer

We're looking for a Senior Software Engineer to join our Trusted Enterprise Platform team 1 the group that keeps Multiverse secure, scalable, and architecturally sound as we grow.

You'll build and maintain the foundational services every product team depends on: authentication, single sign-on, safe release tooling, notification delivery, and the systems that turn regulatory obligations like GDPR into working, reliable code. Your work won't always be visible to end users, but it's what lets our engineers ship with confidence and our customers trust us with their data.

This is a backend-leaning full-stack role for someone who finds genuine satisfaction in building platform capabilities that multiply the effectiveness of the teams around them.

In your first two months, you'll get to know our platform deeply 1 understanding our auth and identity systems end to end and shipping a meaningful contribution to one of our core services.

By months three and four, you'll take ownership of a workstream 1 whether that's improving SSO integration, building safer release infrastructure, or advancing our preference and consent centre 1 and start influencing architectural decisions.

By six months, you'll be a trusted owner of one or more platform domains: shaping the roadmap, supporting your teammates, and visibly reducing friction and risk for product teams across the organisation.

What you're looking for

• You have solid backend experience 1 strong data modelling, clean API design, and an eye for well-drawn system boundaries. You've worked in cloud environments and are comfortable with containerised infrastructure. You write code that others can read, maintain, and build on.
• You don't need to have built an identity provider from scratch, but you should be able to reason about authentication and authorisation flows, understand their security trade-offs, and have worked with concepts like OAuth or SSO in a B2B context. We'll help you go deeper on the specifics of our stack.
• We work primarily in TypeScript and you'll need to be productive in it from day one 1 experience with Elixir is a plus. Familiarity with event-driven systems or a history of pulling shared services out of a monolith are both things that would set you apart.
• We care about depth and impact, not years on a CV. At this level, we're looking for someone who:
  • writes code that serves as a clear example for the rest of the team
  • takes genuine ownership 1 not just launching features, but ensuring systems stay healthy over time
  • engages with stakeholders directly and helps other engineers move faster
  • mentors teammates through thoughtful code reviews and good documentation
• We're an AI-forward team. We use tools like Claude, Cursor, and Gemini daily to write, review, and debug code 1 and we genuinely enjoy sharing what's working. We're not prescriptive about which tools you use, but we do care that you're curious about how AI is changing the way software gets built, and open to experimenting as new things emerge.
