Responsibilities
- Own the technical delivery strategy, including work decomposition, sequencing, integration, and incremental end-to-end delivery.
- Shape and drive adoption of cross-cutting architecture patterns for resilience, event-driven integration, idempotency, and observability.
- Establish scalable engineering practices including test-driven development, contract testing, continuous integration, trunk-based development, and vertical slicing.
- Coach engineers and architects through pairing, design reviews, code reviews, and hands-on technical guidance.
- Apply domain-driven design across bounded contexts, aggregates, domain events, repositories, context mapping, and anti-corruption layers.
- Define testing strategy for event-driven microservices, covering unit, integration, contract, and end-to-end testing.
- Develop reusable service patterns, templates, and architectural guardrails that help teams become self-sufficient.
- Drive adoption of AI-assisted engineering across architecture, design, coding, testing, and delivery workflows.
Requirements
- Significant experience as a senior or principal engineer or technical lead delivering distributed systems in production.
- Deep hands-on experience with modern Java or Kotlin, Spring Boot, and microservices architectures.
- Experience shaping technical strategy and architecture direction across multiple teams.
- Strong experience with event-driven architecture, Kafka, event sourcing, eventual consistency, and integration patterns.
- Practical strategic and tactical application of domain-driven design.
- Experience designing resilience patterns for distributed systems, including circuit breakers, retries, timeouts, bulkheads, and graceful degradation.
- Proven ability to coach and influence engineers and architects toward pragmatic engineering excellence.
- Experience applying AI tools to accelerate development, testing, or delivery workflows.
- Experience with iterative delivery approaches such as vertical slicing, walking skeletons, and integration-first development.
- Familiarity with payments, financial services, or high-volume transactional domains is preferred.
- Exposure to Confluent Cloud, AWS, Kubernetes, GitLab CI, Dynatrace, or distributed tracing is preferred.
