Job Description :

We are looking for a Principal Java Backend Engineer or Staff Java Backend Engineer to lead the design and delivery of scalable, integration-heavy backend systems. This role requires a hands-on technical leader who can unblock teams, influence stakeholders, and collaborate directly with client engineering teams to drive solutions.

You will operate at a Principal Engineer level, balancing architecture leadership with hands-on development.

Requirements :

We are looking for a highly experienced Principal Backend Engineer to join our Domain Services portfolio. This is a high-impact role within an established, integration-heavy enterprise environment.

The successful candidate will step into a complex delivery landscape and help strengthen technical direction, improve engineering standards, and drive better ways of working through technical credibility and influence.

This is not a greenfield role; it requires someone comfortable navigating ambiguity, improving existing systems, and leading change without formal authority.

Technical Leadership :

- Lead architecture and design of domain services and integration-heavy systems.

- Act as a technical escalation point to unblock teams and resolve complex challenges.

- Drive best practices in microservices, event-driven architecture, and API design.

- Ensure systems are scalable, resilient, and cloud-native.

- Improve engineering standards, quality practices, and technical direction across teams.

Hands-On Engineering :

- Develop backend services using Java (11+) and Spring Boot.

- Build and maintain event-driven systems using Kafka.

- Design and implement REST APIs (GraphQL experience is a plus).

- Work with MongoDB for high-volume, distributed workloads.

- Contribute directly to code, reviews, and production issue resolution.

Architecture & Integration :

- Design secure, integration-focused workflows across systems.

- Apply domain-driven design principles.

- Improve performance, scalability, and observability.

- Work within integration-heavy enterprise systems.

Cloud & Engineering Practices :

- Experience working with Microsoft Azure (preferred).

- CI/CD and DevOps-aware engineering mindset.

- Strong testing discipline (JUnit, Mockito).

- Gradle or modern build systems.

Leadership & Stakeholder Collaboration :

- Influence architectural decisions across teams.

- Partner with client stakeholders to unblock delivery challenges.

- Provide mentorship and technical guidance to engineers.

- Drive improvement through credibility rather than authority.

- Comfortable working in established, multi-team enterprise environments.

Required Experience :

- 13+ years in backend engineering.

- Deep expertise in Java and distributed systems.

- Strong experience with event-driven architectures (Kafka).

- Experience improving legacy systems and integration-heavy platforms.

- Proven ability to influence technical direction across teams.

Nice to Have :

- Micronaut framework experience.

- Retail or enterprise-scale domain exposure.

- Multi-cloud exposure (Azure/AWS).

Benefits :

We Offer :

- Competitive salary.

- Annual bonus, subject to company performance.

- Access to Udemy online training and opportunities to learn and grow within the role.
