Job Overview:
We are seeking an experienced and highly skilled Senior Software Engineer to design, build, and support scalable Multifamily application platforms and cloud-native services. This role focuses on hands‑on engineering across Java‑based microservices, event‑driven distributed systems, APIs, MongoDB, AMQ, Kubernetes, AWS, CI/CD automation, and production‑grade backend capabilities that are secure, resilient, observable, and aligned with business needs.

• Design, develop, test, deploy, and support backend application capabilities, including Java-based microservices, REST APIs, event‑driven distributed services, and AMQ‑based messaging integrations.
• Apply strong hands‑on engineering skills to build scalable, secure, resilient, observable, and maintainable backend services using modern software design patterns and cloud‑native practices.
• Collaborate closely with Product Owners, architects, business stakeholders, and cross‑functional technology teams to clarify requirements, align on technical approaches, manage dependencies, and deliver business outcomes.
• Build and enhance backend services using Java, Spring Boot, REST APIs, microservices architecture, MongoDB, AMQ messaging, Kubernetes, AWS, CI/CD pipelines, and automated testing frameworks.
• Create proofs of concept, demos, and prototypes to evaluate emerging technologies and validate new ideas.
• Follow and strengthen software engineering standards, including clean code, scalable design, code reviews, automated testing, deployment discipline, application security, observability, and operational readiness.
• Ensure backend solutions are delivered with appropriate compliance, auditability, security, resiliency, accessibility, data quality, performance, and production support considerations.
• Support production operations by participating in incident triage, root‑cause analysis, application monitoring, logging, alerting, recovery practices, and continuous improvement of backend service reliability.
• Contribute as a senior individual developer by independently solving complex technical problems, improving existing codebases, reducing technical debt, and helping establish reusable backend engineering patterns.
• Promote a culture of ownership, collaboration, continuous improvement, and engineering excellence by sharing knowledge, documenting solutions, and supporting effective delivery within the team.

• 8+ years of related software engineering experience with strong hands‑on backend development expertise in enterprise application environments.
• Demonstrated experience delivering complex backend technology initiatives across microservices, APIs, AMQ‑based messaging, integration services, data platforms, cloud‑native deployments, and platform modernization.
• Required hands‑on experience with Java, Spring Boot, REST APIs, microservices architecture, MongoDB, AMQ or similar messaging platforms, CI/CD pipelines, automated testing frameworks, and SQL or relational databases.
• Very seasoned experience in AWS and event‑driven distributed systems is required, and Kubernetes experience is a must.
• Strong background in backend software engineering, API design, data modeling, MongoDB schema design, event‑driven architecture, asynchronous messaging, and enterprise integration patterns.
• Experience applying software engineering standards, including clean architecture, scalable design, secure coding practices, automated testing, peer reviews, deployment discipline, compliance standards, and production readiness.
• Proven ability to evaluate…
