We’re looking for an experienced Contract Tech Lead to take ownership of a critical Pricing & Billing capability, bringing complex pricing, tariffs and billing logic in-house from third-party providers.
You’ll be the technical authority and hands-on leader, guiding a team to design and build robust, scalable services on .NET and Azure, with opportunities to apply AI (Codex) where it adds real value.
This is a high-impact role with visibility, autonomy, and the chance to shape the technical direction of a core business platform.
Key Responsibilities
- Technical leadership across the Pricing & Billing domain, acting as the go-to SME
- Drive key architecture and design decisions to ensure scalable, maintainable solutions
- Lead and mentor engineers, setting standards and building a high-performing delivery culture
- Own quality across the build: code reviews, QA approach, testing strategy and release readiness
- Design and deliver complex pricing and tariff models, billing workflows, and integrations
- Manage the transition from third-party solutions to in-house capability, reducing dependency and increasing control
- Collaborate closely with product, engineering leadership and stakeholders to align delivery with business goals
- Identify where AI can enhance pricing and billing outcomes (e.g., optimisation, anomaly detection, decision support)
Person Requirements
- Proven experience as a Tech Lead / Senior Engineer leading teams and making architecture-level decisions
- Strong .NET expertise (C#) building backend services and APIs
- Solid Azure experience (e.g., App Services/Functions, messaging, storage, monitoring and security patterns)
- Experience delivering complex pricing, tariffs, rating and billing systems (or similarly rules-heavy financial/transactional domains)
- Demonstrable ability to set engineering best practices: clean architecture, testing, CI/CD, observability
- Confident stakeholder management skills and the ability to translate business needs into technical delivery
- Comfortable working with (and migrating away from) third-party platforms and vendors
