Senior Software Engineer II, Backend

Who you are

You have 5+ years of backend engineering experience building production systems at scale — you've owned services from design through deployment and have navigated complex distributed systems issues with confidence. Your deep expertise in Java and Spring allows you to ship high-throughput APIs that handle millions of requests, and you have strong opinions on service architecture, dependency injection, and testing strategies. You thrive in collaborative environments, working closely with diverse teams of engineers, product managers, designers, and researchers, where everyone's input is valued. You understand the importance of user satisfaction and are driven to enhance the customer experience through your technical contributions. You are adaptable and appreciate the flexibility of a hybrid work model, allowing you to balance remote work with in-office collaboration. You are eager to help small and medium-sized businesses achieve their goals through the enhancements you bring to life in HubSpot's products.

Desirable

Experience with cloud platforms like AWS or Azure would be a plus, as would familiarity with containerization technologies such as Docker. Knowledge of database management systems, particularly PostgreSQL, is also beneficial. You are comfortable with agile methodologies and have a proactive approach to problem-solving, always looking for ways to improve processes and systems.

What you'll do

As a Senior Backend Engineer at HubSpot, you will write and ship impactful production code that directly contributes to user satisfaction and company growth. You will design, build, and evaluate new features and tools that drive revenue and help businesses grow better. Collaborating in a diverse, cross-functional team, you will work closely with product managers and researchers to ensure a seamless experience for users. You will gain a deep understanding of how HubSpot functions as a business and leverage that knowledge to enhance the products we offer. Your role will involve participating in code reviews, mentoring junior engineers, and contributing to the overall technical direction of the team. You will also be responsible for monitoring production systems, troubleshooting issues, and ensuring high availability and performance of the services you build.
