Job Description We are looking for a Senior Software Engineer who loves to be deep in the code. You're the kind of engineer who takes pride in writing clean, thoughtful Java, obsesses over system design, and doesn't shy away from working on production issues. You'll work on building and managing microservices end-to-end - from design and implementation through deployment, monitoring, and troubleshooting in live environments. This is a hands-on, heads-down role where your technical instincts will directly shape the reliability and performance of BILL's financial platform. We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters. Qualified candidates will receive consideration for employment regardless of their race, color, ethnicity, religion, sex (including pregnancy), sexual orientation, gender identity and expression, marital status, national origin, ancestry, genetic factors, age, disability, protected veteran status, military or uniformed service member status, or any other status or characteristic protected by applicable laws, regulations, and ordinances. If you need assistance and/or a reasonable accommodation due to a disability during the application or recruiting process, please send a request to HR@insightglobal.com.
