Senior Engineer

About this role

Responsibilities

• Define, evolve and defend domain boundaries, aggregates and bounded contexts using domain-driven design, and make sure the model reflects how the business actually works.
• Design, build and operate event-driven flows in production, from event modelling and schema design to monitoring, failure handling and recovery.
• Introduce and maintain consumer-driven contract testing in CI so that teams can change their services with confidence that shared interfaces still hold.
• Investigate architectural alternatives, make decisions, and document and justify them (for example through ADRs), on your own initiative rather than waiting for a specification.
• Form and communicate a view on where your domain's architecture should go over the next year or two, and bring colleagues along with you.
• Pick up new technologies and patterns when the problem calls for it and take them all the way into production.

Requirements

• Recent, hands-on experience applying domain-driven design in production systems, including owning decisions on boundaries and aggregates.
• Experience building and running event-driven architecture in production, not just consuming events built by others.
• A modern approach to testing, including practical experience with contract testing (e.g. Pact or similar) as part of a CI pipeline.
• A track record of making and owning architectural decisions independently, including in situations where requirements were unclear.
• Evidence that you learn new technology on your own and apply it in real work, without needing formal training or central guidance.
• Comfort taking ownership
