Job description


Software Engineer – Platform
Are you looking for more in life than just building another web app? Does upending cyber security resonate with you? We're a rapidly expanding cybersecurity company revolutionizing vulnerability management for organizations of all sizes. For our customers, vulnerability management has always been a game of catch-up, with limited asset coverage and manual processes. Nucleus' primary mission is to create a fast, scalable platform that not only addresses these challenges but also makes vulnerability management simple, fun, and effortless. Currently, we're looking for a passionate Mid-Career Software Engineer to join our growing team of engineers.

What You Will Do: 
  • Own the end-to-end lifecycle of data driven analytic features—from prototyping and experimentation to production deployment and customer delivery
  • Build, and evolve our security analytics platform to enable scalable data ingestion and post ingestion processing
  • Collaborate with engineering, product, and data teams to translate ambiguous requirements into robust technical solutions
  • Diagnose, triage, and resolve production issues quickly, ensuring reliability and continuous improvement of deployed systems
The following skills and experience are key to succeeding in this role
  • Background in data analytics, data science, and/or data warehousing
  • Familiar in SQL, including performance optimization and complex query design.
  • Proficiency in PHP or similar language for data processing
  • Experience working in a test-driven environment and writing unit and integration tests
  • Proven ability in technical troubleshooting
  • Capable of working independently as well as collaboratively with teams across different time zones
Preferred Qualifications: 
  • Experience working with vulnerability scanning technologies on any part of the tech stack (e.g., SCA, SAST, DAST, IAST, VM Scanning, Container, etc.) 
  • Experience with column store databases and columnar data, especially using SingleStore/MEMSQL
  • Experience integrating AI/LLM-driven features with data platform
  • Familiarity with Agile/Scrum methodologies in a professional setting.
  • Experience maintaining applications on Linux platforms in cloud environments.
  • Experience with modern versions of PHP, and the Zend and Laminas Frameworks
  • Experience with modern versions of React, Vite and Tanstack libraries
  • Improve key components of the application to enable data scalability.

Why You Should Be Excited 
  • Nucleus is a truly unique solution that’s defining a market AND making an actual impact.  
  • We’re biased, but you will get to work with one of the best teams in security. We have a lot to get done and we work extremely hard, but we have fun in the process.  
  • Outstanding benefits - flexible PTO, 401k company contribution (not a match, a contribution), 100% company-paid healthcare, fully remote… just to start 

 
Additional Information 
At Nucleus we are committed to achieving excellence in our field by combining diversity, collaboration, teamwork, and pride in our work. All qualified applicants will receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or disability.
