Software Engineer (.NET and Angular)

About the Role

SwiftB2B is building an AI operating system for global supply chains. We are looking for engineers who own features end-to-end and treat reviewing AI-written code as the real work.

Key Responsibilities

• Own features end to end: the Angular screen, the .NET service, the data model, the API contract, and the runbook.
• Work with Claude Code and similar AI coding tools daily. Generate fast, review hard, and maintain a written review standard.
• Publish and agree API contracts before building.
• Design and prove event contracts on Kafka, demonstrating delivery guarantees by replay.
• Build identity and access on Keycloak and OpenID Connect, reviewed before build.
• Take ownership of at least one primary database (SQL Server, PostgreSQL, or MongoDB) and maintain working depth in the other two.
• Ship through a secure CI/CD pipeline with automated tests, demonstrating accessibility and performance.
• Build agents that perform real work in the product (exception triage, document handling, customer-facing drafts) with a written boundary and a tested human gate.
• Hand over features cleanly, ensuring another engineer can modify them without needing further questions.

Requirements & Tech Stack

• Real production experience across the stack: C# and .NET on the back end, Angular and TypeScript on the front end. Angular 17 or later preferred.
• Strong relational data modelling on at least one of SQL Server or PostgreSQL. MongoDB experience is a plus.
• Designed REST APIs consumed by other teams, understanding the cost of ignoring idempotency, versioning, and backward compatibility.
• Experience with event-driven systems; Kafka preferred, any service bus is fine.
• Hands-on with OAuth2 and OIDC. Keycloak is a plus.
• Serious use of AI coding tools with "war stories" about working with their produced code.
• Experience building agents with an SDK (Claude Agent SDK, Semantic Kernel, LangGraph) is a strong plus.
• Automated testing as a habit, not a phase. Playwright or similar for the front end.
• Secure pipeline experience on Azure DevOps or GitHub Actions.
• Azure experience. AZ-204 is a nice to have.

Qualifications

• A background in supply chain, logistics, or B2B enterprise software is an advantage.
• A degree in Computer Science or a related field, or equivalent practical experience.

If you have shipped features that others maintained without you, and you have strong views on reviewing AI-generated code, we encourage you to apply.
