Senior Software Engineer II - 2026

We are looking for a Senior Software Engineer with strong Java experience (6+ years) to design, build, and own high-quality, scalable backend services in a high-volume, event-driven environment. This role sits in the integration layer of a large-scale platform migrating from legacy systems to a modern, reactive, cloud-native stack. You will own features end-to-end, from design through deployment and production support, and help raise the technical bar for the team.

Responsibilities:

• Design, develop, test, and maintain backend services and APIs using Java.
• Write clean, maintainable, and well-documented code following best practices and coding standards.
• Own high-level and low-level design (HLD/LLD) for assigned modules/services.
• Design and build event-driven services and integrations (e. g., Kafka), including idempotency, message ordering, and resilient handling of unreliable upstream and downstream systems.
• Design and build clean API and error contracts that decouple consumers from the systems behind them.
• Coach and Support Junior Engineers while fostering high code quality and engineering excellence.
• Collaborate closely with product managers, QA engineers, and other developers to deliver features on time.
• Implement unit, integration, and (where relevant) performance tests to ensure software quality.
• Troubleshoot and debug production issues, performing root cause analysis and implementing long-term fixes.
• Participate in code reviews, providing and receiving constructive feedback.
• Contribute to continuous improvement of development processes, tooling, and automation (CI/CD).
• Ensure security, scalability, and reliability are considered throughout the development lifecycle.
• Stay current with Java and related ecosystem technologies and bring new ideas to the team.

Requirements:

• Bachelor's degree in computer science, engineering, or equivalent practical experience.
• Strong programming skills in Java (Java 11+) with a solid understanding of OOP, concurrency, and multithreading.
• Experience building server-side applications using a Java framework (e. g., Spring/Spring Boot).
• Good understanding of RESTful API design and implementation.
• Experience with relational databases (PostgreSQL) and SQL, including query optimization and schema design.
• Experience with reactive, non-blocking programming (e. g., Spring WebFlux / Project Reactor); or a strong grasp of non-blocking I/O and backpressure with the ability to ramp quickly.
• Experience designing and operating event-driven systems using messaging/streaming (e. g., Kafka), including delivery guarantees, idempotency, and schema evolution.
• Experience integrating heterogeneous systems: resilient service-to-service and third-party integrations, with clean API and error-contract design.
• Ability to reason from first principles about unfamiliar systems and tradeoffs, not just recall tools and syntax.
• Familiarity with version control systems (e. g., Git) and collaborative development workflows.
• Solid understanding of software engineering fundamentals: data structures, algorithms, and design patterns.
• Experience with automated testing (unit/integration) and testing frameworks (e. g., JUnit).
• Strong problem-solving skills and ability to debug complex issues.
• Good communication skills and ability to work effectively in a team environment.
• Experience with DevOps tools such as Dynatrace or Splunk.

Preferred Qualifications:

• Experience with cloud platforms (e. g., AWS, Azure, GCP) and cloud-native architectures.
• Experience with DAGs, AWS S3 and Lambda.
• Hands-on experience with containerization and orchestration (Docker, Kubernetes).
• Deeper experience with the Kafka ecosystem: schema registry, AVRO, event schema governance, and stream processing (e. g., Kafka Streams).
• Familiarity with microservices, architecture, and distributed systems.
• Experience with build and CI/CD tools (e. g., Harness, GitHub Actions).
• Knowledge of NoSQL databases (e. g., MongoDB, Redis, Cassandra).
• Experience with performance optimization and application monitoring.
• Experience with Airflow, Python, Harness, and/or other technologies.
• Experience with Jira/Confluence.
• Familiarity with GraphQL and API federation.

Soft Skills:

• Well-equipped to take a leadership role to ensure quality delivery to commitments.
• Ability to break down complex problems into actionable tasks.
• Openness to feedback and willingness to mentor and be mentored.
• Proactive, collaborative, and comfortable working in an agile environment.
• Continuous learning mindset and a passion for staying up-to-date with the latest technologies and trends.
