Full Stack Engineer

Abnormal AI is revolutionizing cybersecurity by leveraging AI-native technologies to combat modern cyber threats. We’re building a team of top-tier engineers who are excited to use Generative AI tools like Cursor, GitHub Copilot, and Claude to redefine how software is built—faster, smarter, and more efficient.

We are seeking a highly skilled Software Engineer II to help shape the future of AI-powered application development. If you’re passionate about cutting-edge technology, scalable systems, and solving real-world challenges, this is your opportunity.

Abnormal AI is looking for a Senior Full Stack Engineer to join the Behavioral Security Products team. Our company is built around the idea of first understanding the person we are trying to protect using baselines of historic behaviour and ML models to determine what normal looks like for every employee of a company. Our team builds the features that take those insights and show our customers what is happening with their employees and their systems, as well as the tools and workflows for dealing with some of the most critical attacks companies can face: account takeovers.

The role will involve building out features to enable customers to more quickly diagnose potentially suspicious behaviour, to make it easier to catalogue that behaviour as an attack or as benign, and more controls to optimise how the system will behave according to their needs. It will require qualities such as:

• Strong communication skills and proven ability to work autonomously and asynchronously with remote collaborators and stakeholders
• Well rounded and can switch contexts between building frontend UI components and backend APIs
• Looking to grow as an engineer as part of a strong team, learning from established engineers, product managers, and designers
• Know what it takes to be successful working with remote collaborators and stakeholders, and are experienced with remote management
• Detail driven and care about code quality, testing, and performance
• Growth-oriented, looking to increase impact, responsibility, and ownership over time
• You bring up ambiguities and and clarify decisions with leadership instead of improvising solutions on the go

• Work on production systems to stabilise and improve existing features
• Collaborate with engineers, Product Managers, and Designers to define, build, test, launch, and support new product features
• Responsible for both development and testing of software
• Collaborate with Customer Support and Sales Engineering organisation on production issues and sales solutions
• Provide code reviews for other engineers to catch bugs & problems before they make it into production
• Demonstrate good judgement in selecting methods and techniques for obtaining solutions

• 5+ years of full stack web development experience in Python, Django, JavaScript, HTML5, React (or similar Frontend UI frameworks such as Vue, Angular), CSS
• 3+ years of production support experience for enterprise-class customers
• At least 1 year of system design experience
• Proven experience owning testing as well as development of all software solutions
• Proven experience working with agile development methodologies (both scrum and kanban)
• Proven experience working effectively with cross-functional teams across multiple time zones with with remote stakeholders
• Familiarity with AI development tools such as Cursor, GitHub Copilot, or Claude.
• BS degree in Computer Science or related engineering field

• Experience with Airflow, Celery, AWS and/or Azure, Postgres
• Experience with API platform development
• Experience with Go

Once you apply, you’ll be invited to our AI-powered Development Challenge, where you’ll gain hands-on experience with AI-powered tools like Cursor and Copilot to build real-world application features. This challenge is a take-home assignment, requiring 2-4 hours of work to be completed within one week - apply when you’re ready!
