Senior Software Engineer - Trusted Enterprise Platform

Senior Software Engineer

We are hiring a Senior Software Engineer to join our Trusted Enterprise Platform team and build the systems that keep Multiverse secure, compliant, and architecturally sound as we scale.

You will build and maintain the foundational services that every product team depends on but few users ever see: authentication and single sign-on, safe release infrastructure, notification delivery, universal preference management, and the technical surface area where regulatory obligations like GDPR become working code. Your work will be the reason other engineers can ship with confidence and customers can trust us with their data.

We are looking for a full-stack engineer who leans towards the backend and finds satisfaction in providing leverage. You are the kind of person who enjoys building a platform capability leveraged by ten teams, but serving thousands. You care about getting the abstractions right, because you know that a poorly designed auth flow or a leaky preference centre creates problems that compound across the entire organisation.

The Challenge: Your First 6 Months

• Months 1 to 2: Learn the platform landscape, understand our auth and identity systems end to end, and ship your first meaningful contribution to one of the core services.

• Months 3 to 4: Take ownership of a workstream, whether that is improving SSO integration, building out safe release infrastructure, or advancing the preference centre. Start influencing architectural decisions.

• Months 5 to 6: You are a trusted owner of one or more platform domains. You are shaping the roadmap, mentoring teammates, and your work is visibly reducing friction and risk for product teams across the organisation.

Your Impact

• Technical Excellence: You will produce clean, extensible code that serves as a best-practice example for the squad, possessing a strong understanding of non-functional requirements like security and scalability.

• System Ownership: You won't just launch bugs-free code; you will ensure proactive monitoring is in place, defining new technical metrics to guarantee the health of Multiverse's systems.

• Strategic Execution: You will advocate for incremental delivery, taking a fail-fast approach to complex problems and helping the squad manage technical debt effectively.

• Mentorship & Uplift: You will actively mentor more junior members, conducting thoughtful code reviews and producing documentation that helps others ramp up quickly.

• Cross-Functional Influence: You will engage stakeholders directly to understand their problems, building strong relationships to achieve business objectives across several squads.

How We Work With AI

At Multiverse, AI is our engine, not an add-on. We want every engineer to use AI tooling as a core part of how they work, not as an experiment or a side interest. That means using AI-assisted development tools (Claude, Cursor, Gemini, etc.) daily to write, review, and debug code faster. It means reaching for an LLM before reaching for Stack Overflow. It means being willing to prototype internal automations that save the team hours, not just yourself.

You should be genuinely curious about how AI is reshaping software development, comfortable adopting new tools as they emerge, and excited about the idea that infrastructure and platform work will look meaningfully different in two years than it does today.

Operating Principles in Action

• Solve for Customer Value: You prioritize the balance between high security and user friction. You design identity flows that protect our customers without slowing them down.

• Drivers, Not Passengers: You don't wait for a legal "requirement" to fix a privacy flaw. You lead the solution, ensuring compliance is an architectural feature, not an afterthought.

• Be Decisive, Even in Ambiguity: You are comfortable launching "imperfect" platform tools to get internal feedback early, course-correcting quickly based on how other engineers use your APIs.

• AI to Deliver Outcomes: You treat AI as our engine. You look for opportunities to integrate LLMs or AI-augmented tooling into our developer workflows to accelerate our platform's maturity.

What We Are Looking For

Technical Foundation

• Backend Center of Gravity: 5+ years of experience with a focus on data models, APIs, and system boundaries.

• Cloud-Native Instincts: Deep comfort with AWS, containerization (Docker/Kubernetes/ECS), and Infrastructure-as-Code.

• Clean Code: A track record of writing modular, tested, and readable code in TypeScript, or Elixir.

Technical Leadership & Mindset

• Product Mindset for Platforms: You treat internal engineers as your users, caring deeply about developer ergonomics and API documentation.

• Identity Experts: Hands-on experience building or significantly contributing to auth and identity systems in a B2B org (SSO, SAML, OAuth).

• Release Architects: You understand the difference between deployment and release and have managed enterprise release cycles at scale.

What Would Set You Apart

• Experience with event-driven architectures (Kafka, RabbitMQ, SQS).

• A history of extracting shared services from monolithic codebases.

Benefits

• Time off - 27 days holiday, plus 5 additional days off: 1 life event day, 2 volunteer days, 2 company-wide wellbeing days (M-Powered Weekend) and 8 bank holidays per year

• Health & Wellness - private medical Insurance with Bupa, a medical cashback scheme, life insurance, gym membership & wellness resources through Wellhub and access to Spill - all in one mental health support

• Hybrid work offering - for most roles we collaborate in the office three days per week with the exception of Coaches and Instructors who collaborate in the office once a month

• Work-from-anywhere scheme - you'll have the opportunity to work from anywhere, up to 10 days per year

• Space to connect: Beyond the desk, we make time for weekly catch-ups, seasonal celebrations, and have a kitchen that's always stocked!
