Senior Software Engineer

Why This Job is Featured on The SaaS Jobs

This Senior Software Engineer role stands out in SaaS because it sits at the intersection of product delivery and platform stewardship: cloud infrastructure, deployment automation, and security embedded into the software lifecycle. For subscription software, those capabilities directly influence reliability and trust, and the remit suggests work across distributed services rather than a single application area. The emphasis on applying design patterns across complex systems signals a platform that has matured beyond early prototypes and is now being intentionally shaped for maintainability.

From a long-term SaaS career perspective, the scope builds durable leverage: architecting microservices boundaries, hardening CI/CD, and operationalizing security checks are competencies that translate across most modern SaaS stacks. Exposure to incident response and root-cause analysis also develops the production mindset expected of senior engineers in always-on environments. The mention of evaluating new approaches, including LLM-driven methods, adds a forward-looking dimension without making the role purely experimental.

This position suits an engineer who prefers systems thinking over feature-only delivery, and who enjoys guiding technical direction through reviews and mentoring. It will likely appeal to someone comfortable balancing hands-on coding with cross-functional alignment across product and engineering, in a hybrid working model.

Job 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.

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:

8+ years of professional software engineering experience, with deep 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.
