Core Responsibilities
Backend engineering and ownership
- Own design, build and run of the .NET services and BFF behind different core services related to booking, payments and loyalty.
- Hold the integration contracts, including failure handling, idempotency and retry behaviour on transactions.
- Use agentic coding tools as the default working mode for implementation, refactoring, test generation and codebase exploration.
- Set the team's rules for AI-assisted work: what tools are used for, what they are not used for, and what must be human-verified before merge.
- Keep context artifacts current (repo conventions, agent instructions, prompts and scripts) so the whole backend team gets the same lift, not just you.
- Review backend PRs, human- and AI-authored, with particular attention to hallucinated APIs, deprecated calls, silent complexity on hot paths and tests that assert nothing.
- Support 1-2 other backend engineers by building and reviewing alongside them, and act as the technical counterpart to the Technical Director, product and QA.
- Take part in RCA on production failures and turn findings into fixes, logging and guardrails.
- Backend: C# / .NET 8+
- ASP.NET Core
- REST APIs / BFF pattern
- Redis
- AI coding: Claude Code
- OpenAI Codex
- GitHub Copilot
- MCP servers
- agent instruction files
- Platform: Azure
- Docker
- GitHub Actions
- ArgoCD
- New Relic
- Integrations: Checkout.com (payments, 3DS)
- Strapi CMS
- 7+ years building backend services in C# / .NET, including 2+ years owning a production system, and still writing production code daily.
- Demonstrable daily use of agentic coding tools (Claude Code, Codex, Copilot or equivalent) on production code, with concrete examples of what changed in their delivery: scope, cycle time, test coverage, refactors they would not otherwise have attempted.
- Strong code review practice, including a clear personal method for catching AI-generated defects.
- Experience integrating third-party transactional APIs (payments, PSPs, booking or ticketing engines) where partial failure has commercial consequences.
- Worked in fast-paced delivery with short cycles, feature flags and frequent releases.
- Set or documented AI-assisted development standards for a team (review policy, agent instructions, prompt or context libraries).
- High-volume transactional or booking platforms; multi-market or multi-currency systems.
- Azure, distributed tracing and production debugging with New Relic or similar.
- Comfortable working across a React and Flutter client surface, and with CMS-driven content.
