Senior Software Engineer | Enterprise | Full-Stack

About This Opportunity

We are representing a confidential AI technology company expanding their enterprise capabilities in London. Our client is transitioning from consumer-focused products to mission-critical enterprise platforms, and we need a Senior Full-Stack Software Engineer to architect revenue-critical systems that enable global organizations to securely deploy AI solutions at scale.

This role sits within the team responsible for the revenue engine—building the subscription architecture, identity management, and enterprise tooling that allows Fortune 500 companies to provision and manage advanced technology for tens of thousands of employees.

Your Responsibilities

• Design and ship complex, high-stakes features including enterprise licensing, automated seat provisioning, and subscription management systems where user experience must be instant and billing logic must be immutable
• Build administrative tools and dashboards that empower CIOs and IT Directors to manage enterprise deployments, translating complex backend constraints (RBAC, rate limits, SSO) into elegant UI workflows
• Work directly with Sales, Product, and Finance stakeholders to translate business objectives into scalable technical architectures that support annual recurring revenue growth
• Ensure system reliability for billing and financial systems, building for idempotency and resilience while maintaining high-velocity frontend experiences
• Traverse the full stack—designing React components for admin consoles and debugging distributed backend transactions as needed
• Leverage AI-powered development tools to accelerate velocity, using them for boilerplate code, test generation, and debugging to focus cognitive energy on architectural decisions

What We're Looking For

• Full-stack fluency with comfort moving between frontend (React) and backend (C#/.NET or similar) technologies
• Product-first mindset with deep care for customer journeys and understanding how features enable enterprise sales
• Interest in enterprise B2B SaaS domains including Identity (SAML/SSO/SCIM), monetization, compliance, and multi-seat subscription architectures
• High agency—you proactively identify inefficiencies and fix them without waiting for permission
• Understanding that billing and financial systems require special attention to auditability, data integrity, and fault tolerance
• Experience or strong curiosity about revenue-critical systems and how technical architecture impacts business outcomes
• Ability to communicate effectively with technical and non-technical stakeholders across sales, finance, and product teams
