Senior Java Software Engineer
Application Deadline: 31 May 2026
Department: Engineering
Employment Type: Full Time
Location: San Ramon, CA
Reporting To: Serge Kurenkov
Compensation: $140,000 - $170,000 / year
Description
We are seeking an experienced Senior Software Engineer with a strong understanding of software design patterns and the ability to apply them effectively across complex systems. In this role, you will lead key initiatives in cloud infrastructure, automation, and security-using solid engineering principles and well-chosen patterns to enhance reliability, scalability, and maintainability.
You will collaborate closely with product and engineering teams to refine the development lifecycle, strengthen deployment pipelines, and enhance the overall resilience and security of the platform.
This is a hybrid-remote position and is expected to be on-site in the New York office 2 days per week, with the remaining 3 days remote.
What You Will Do:
  • Design and Implement Core Systems: Build scalable, maintainable services and components, applying appropriate design patterns to ensure clear structure and long-term reliability.
  • Enhance Cloud Infrastructure: Develop and evolve AWS-based systems with strong architectural practices and high operational quality.
  • Automate Security and Quality: Integrate automated testing, security checks, and validation tools directly into the engineering pipeline.
  • Collaborate Across the SDLC: Work closely with product and engineering teams to shape designs, refine implementation plans, and ensure smooth delivery.
  • Mentor Engineers: Provide guidance on architecture, design decisions, and engineering best practices.
  • Drive Technical Evolution: Research and introduce new tools, frameworks, and approaches-including AI/ML or LLM-driven methods-that enhance overall engineering efficiency.

What You Will Bring to the Team:
  • 10+ years of professional software engineering expertise in Java, Spring, and applying design patterns (GoF, architectural, integration) to build clean, scalable systems.
  • Strong ability to evaluate, select, and apply design patterns to solve complex engineering problems with clarity and maintainability.
  • Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
  • Solid experience building and maintaining distributed, cloud-based systems, ideally on AWS.
  • Strong understanding of microservices architecture, service boundaries, API design, and system modularity.
  • Hands-on experience with CI/CD automation to support reliable software delivery (Jenkins, GitHub Actions, Bitbucket Pipelines).
  • Proficiency with containerization (Docker, Kubernetes) for running and scaling services.
  • Solid understanding of security fundamentals, including IAM, encryption, and secure service-to-service communication.
  • Demonstrated ability to mentor engineers, lead code reviews, and guide architectural decisions.
  • Experience with incident response, debugging distributed systems, and performing root-cause analysis.
  • Familiarity with PHP/Laravel, front-end technologies, and SQL/NoSQL databases is a plus.
  • Interest or hands-on experience applying AI/ML or LLM-driven techniques within engineering workflows. Professional certifications (AWS, Java, Architecture) are a strong plus.
