Security Software Engineer: Anti-Abuse/Trust & Safety

beehiiv is where the world's best newsletters, podcasts, and digital products are built, grown, and distributed.
The platform combines email, podcast hosting, websites, community, and digital products — connected to a single audience and a single set of tools to publish, grow, and monetize.
As we approach $50M in annualized revenue and continue to grow 100% YoY, our rapidly growing product suite and incredibly strong brand positions us for the next stage of hypergrowth.

As a Security Software Engineer specializing in Anti-Abuse, you will play a critical role in protecting our platform and users from malicious and fraudulent activity. You will work in a small, focused team, collaborating directly with our existing Trust & Safety Software Engineering Team to design, build, and maintain our anti-abuse systems. This is a hands-on technical role for someone with a passion for both software engineering and digital security.

Please note that compensation is dependent on experience.

Ideally, you'll have:

Soft Skills and General Experience

• Problem-solving and analytical skills: The ability to break down complex issues into manageable parts and identify the root cause of problems.
• Abstract thinking: The capacity to think creatively and conceptually, especially when dealing with threats that are not yet well-defined.
• Desire to solve hard problems: A persistent and resilient attitude toward challenges, seeking out difficult tasks rather than avoiding them.
• A "hacker" mindset: The curiosity to understand how systems can be exploited and the ability to think like a malicious actor.
• Solid understanding of fundamental computer networking concepts, including subnetting, DNS, and HTTP/S protocols.
• Experience with security tools and technologies, such as WAF rules (e.g., Cloudflare), RECAPTCHA, and other anti-abuse systems.
• Excellent communication: The skill to clearly explain complex technical issues to both technical and non-technical audiences.
• Collaboration: The ability to work effectively in a small team, sharing knowledge and providing constructive feedback during code reviews.
• Adaptability: The flexibility to switch between different projects and technologies as needed in a fast-paced environment.
• Proactive approach: A forward-looking mindset to anticipate future threats and build preventative systems.
• Threat Feed/Intelligence familiarity
• Experience with enterprise fraud/security/kyc tools

Software Engineering

• 5–8+ years of professional software engineering experience
• Experience with Ruby on Rails or similar MVC backend frameworks
• Experience with modern test frameworks (e.g., Playwright, Cypress, Jest, Selenium, Rspec)
• Solid understanding of full-stack web architectures and how systems behave in production
• Strong technical judgment and a track record of owning systems over time
• A quality-first mindset paired with pragmatism and delivery focus
  

What you'll be responsible for:

Develop and implement security and anti-abuse features in our core product.

• Collaborate closely with our existing Trust & Safety Software Engineering Team on projects, strategy, and problem-solving.
• Participate in and lead code reviews for security-related features, ensuring code quality and best practices.
• Support the creation and improvement of machine learning models by assisting with the collation and preparation of training data.
• Work with cross-functional teams to ensure new features are launched with robust anti-abuse and security measures.
• Respond to and investigate security incidents and abuse reports.
• Stay up-to-date with the latest security threats and anti-abuse techniques.
• Implement third-party integrations or products into our production systems.
  

Why this role might be for you:

• Join a fast-growing start-up and a new team
• High impact and high visibility
• You're autonomous and excited about owning projects
• Excited about new challenges and executing creative solutions 

Why this role might not be for you:

• Not a traditional 9-to-5 position
